Abstract:
ABSTRACT Introduction: Maxillary deficiency, also called transverse deficiency of the maxilla, may be associated with posterior crossbite, as well as with other functional changes, particularly respiratory. In adult patients, because of bone maturation and the midpalatal suture fusion, rapid maxillary expansion has to be combined with a previous surgical procedure to release the areas of resistance of the maxilla. This procedure is known as surgically-assisted rapid maxillary expansion (SARME). Objective: This study discusses the indications, characteristics and effects of SARME, and presents a clinical case of transverse and sagittal skeletal maxillary discrepancy treated using SARME and orthodontic camouflage.

Objective Documentation of the application of maxillary distraction osteogenesis using rigid external distraction (RED) with skeletal anchorage combined with predistraction alveolar bone grafting (ABG) in cleft maxilla. Design Case report. Patient A patient with numerous congenital missing teeth and severe maxillary deficiency related to complete bilateral cleft lip and palate with large alveolar bone defect. Intervention The patient received preoperative orthodontic treatment, predistraction ABG, and maxillary distraction osteogenesis using RED with skeletal anchorage. Results Predistraction ABG completely united the cleft maxilla. The united maxilla was successfully advanced by the RED system with skeletal anchorage, despite unsound dentition with numerous congenital missing teeth. Conclusion The present study demonstrates that the combination of predistraction ABG and RED system with skeletal anchorage is effective for the treatment of severe maxillary deficiency related to complete bilateral cleft lip and palate with large bone defect and numerous congenital missing teeth.

Abstract:
Background: The transversal maxillary deficiency represents one of the most frequent skeletal discrepancies of the craniofacial region. The analysis of morphological characteristics of the maxilla can be detrimental for a correct diagnosis and treatment plan. Methods: This paper shows a user-friendly digital workflow involving mirroring, superimposition, and the deviation analysis of 3D models of the maxilla in order to identify the presence of symmetry/asymmetry of the palatal vault. Such information can be helpful to clinicians in order to design an appropriate orthodontic appliance for the treatment of transversal maxillary deficiency. We also describe a case report of a seven-year-old female affected by mild transversal maxillary deficiency associated with anterior openbite. The appliance is designed after a comprehensive evaluation of the morphology of the maxilla performed by using the presented diagnostic digital workflow. Additionally, the orthodontic treatment is assisted by photobiomodulation sessions that expedite the achievement of clinical outcomes.

Abstract:
ABSTRACT Transverse deficiencies should be a priority in orthodontic treatment, and should be corrected as soon as diagnosed, to restore the correct transverse relationship between maxilla and mandible and, consequently, normal maxillary growth. Corrections may be performed at the skeletal level, by opening the midpalatal suture, or by dentoalveolar expansion. The choice of a treatment alternative depends on certain factors, such as age, sex, degree of maxillary hypoplasia and maturation of the midpalatal suture. Thus, the present study discusses different treatment approaches to correct maxillary hypoplasia in patients with advanced skeletal maturation.

Abstract:
Objectives: The aim of this study was to investigate the dimensions and morphological variations of sella turcica and to test whether a relationship exists between sella turcica and transverse maxillary deficiency. Materials and Methods: The cephalometric radiographs of patients older than 17.99 years, which have been taken before the orthodontic treatment, and patient records were analyzed to investigate sella turcica dimensional and morphological analysis. Linear measurements of sella are as follows sella length, sella width, sellar area, sella height anterior, posterior, and median. The sella turcica morphological shape analysis was performed into six groups (normal sella turcica, oblique anterior wall, sella turcica bridge, double contour of floor, irregularities of the posterior part of the dorsum sella, and pyramidal shape of the dorsum sella). The width of the maxillary arch is measured by the digital caliper. Male participants with a maxillary width of less than 30.8 mm and a maxillary width of less than 31.1 mm in female patients in the first molar region were determined as a transverse maxillary deficiency. The mean dimensions of sella turcica and the relationship between cases with transverse maxillary deficiency and non-skeletal anomaly were compared using independent samples t-tests. The transverse maxillary deficiency and the sellar morphology relationship were compared using Chi-square test. Post hoc multiple comparisons and analyzes were performed at 95% confidence interval by Bonferroni correction. Results: The sella length measurements yielded higher values among the patients with transverse maxillary deficiency (P < 0.05). The normal sella morphology had quantitative superiority in patients without skeletal anomaly in comparison with transverse maxillary deficiency cases (P < 0.05). It was observed that the sella turcica bridge had a statistically superiority in patients with transverse maxillary deficiency (P < 0.05). Conclusion: The increased sellar measurement and sella turcica bridging, may provide knowledge about possible transverse maxillary deficiency.

Abstract:
Maxillary deficiency in the transverse dimension is a common problem in children. The conventional management of such malocclusion is with conventional rapid maxillary expansion. The beneficial effects of such an orthodontic therapy are explained in detail in the literature. But there are also negative effects of conventional rapid maxillary expansion. Thus, the improvements in the methods of expansion has led to discovery of miniscrew assisted rapid palatal expansion. The miniscrew assisted rapid palatal expansion are supported by mini implants and thus enable better skeletal expansion of maxilla. This article will discuss the favourable effects, negative effects, and clinical uses of conventional and miniscrew assisted rapid palatal expansion.

Abstract:
Transverse maxillary deficiency may be associated with sagittal or vertical problems of the maxilla or mandible. It may contribute to unilateral or bilateral posterior crossbite, anterior dental crowding, and unesthetic black buccal corridors on smiling. An adequate transverse dimension is important for stable and proper functional occlusion. Surgically, assisted rapid palatal expansion has been the treatment of choice to resolve posterior crossbite in skeletally mature patients. The following case report presents an adult Class III skeletal patient with an anterior open bite and bilateral posterior crossbite which was treated by surgically assisted rapid maxillary expansion with satisfactory outcomes.

Abstract:
Maxillary constriction is a common skeletal craniofacial abnormality, and transverse maxillary deficiency affects 30% of patients receiving orthodontic and surgical treatment. The aim of the study was to analyse craniofacial skeletal changes in adults with maxillary constriction after transpalatal distraction. The study group consisted of 36 patients (16 women) aged 17 to 42 years (M = 27.1; SD = 7.8) with a known complete skeletal crossbite and who underwent transpalatal distraction procedure. The measurements were obtained on diagnostic models, and cephalometric PA radiograms were obtained at time points, i.e., before treatment (T1) and after the completion of active distraction (T2). The analysis of diagnostic models involving the arch width measurement at different levels demonstrated a significant increase in L1, L2, L3, L4, L5, and L6 dimensions after transpalatal distraction. The largest width increase (9.5 mm) was observed for the L3 dimension (the intercanine distance). The analysis of frontal cephalograms displayed a significant increase in W1, W2, and W3 dimensions after transpalatal distraction. The largest width increase (4.9 mm) was observed for the W1 dimension at the level of the alveolar process of the maxilla. Transpalatal distraction is an effective treatment for transverse maxillary deficiency after the end of bone growth. The expansion observed on diagnostic models is close to a parallel segment shift mechanism, with a mild tendency towards a larger opening anteriorly. The maxillary segment rotation pattern analysed based on the frontal cephalograms is close to a hand fan unfolding with the rotation point at the frontonasal suture.

Abstract:
ABSTRACT The maxilla is made up of spongy bone and has one of the least dense bones in oral cavity. Periodontal disease-stimulated teeth loss causes accentuated bone deficiency, both in height and in width by significant resorption of the alveolar bone. Bone remodeling in the region is further complicated by postextraction bone resorption, pneumatization of maxillary sinus, and poor quality of residual alveolar bone. Indirect sinus augmentation is an effective solution for this problem. This case report presents the rehabilitation of maxillary premolar by using indirect sinus lift with implant placement where the bone height and bone width was compromised.

Abstract:
Introduction. Numerous devices have been introduced for correction of Class III malocclusion and maxillary deficiency. Aim. To assess the dentoskeletal effects of miniplates combined with Class III traction in treating Cl III malocclusion and maxillary deficiency in growing patients. Methods. This case describes the treatment of a maxillary-deficient 11-year-old boy by using miniplates. The patient's parents rejected the use of extraoral appliances and major surgical correction; therefore the treatment was done by using Class III elastics connected from two mandibular miniplates to an upper removable appliance. Two miniplates were inserted in the anterior part of the mandible in the canine areas under local anaesthesia. The treatment lasted for 10 months after which favourable correction of the malocclusion was observed. Results. The SNA and ANB angles increased by 5.1° and 4.4°, respectively. Lower 1 to mandibular plane decreased by 3.4°. Conclusions. This case demonstrates that miniplates can be a suitable method to extraoral appliances and major surgery in maxillary deficiency cases.

Abstract:
Introduction: Assessment of maxillary transverse discrepancy requires an accurate tool in order to implement the appropriate treatment plan. Aim: To evaluate the accuracy of Pont’s Index in confirming a transverse maxillary deficiency by comparing its results with the corresponding results yielded by the University of Pennsylvania CBCT analysis. Material and methods: The study was performed on dental casts and CBCT’s of 60 randomly selected patients by adopting a cluster sampling method. The results of Pont’s Index and University of Pennsylvania CBCT analysis were analyzed through McNemar’s test using Excel Data Analysis, and the accuracy indicators for Pont’s Index were computed using MedCalc Ltd. Results: Mc Nemar’s test revealed a p-value of 0.85. The accuracy indicators of Pont’s Index were: sensitivity: 69%; specificity: 16.6%; positive predictive value: 65%; negative predictive value: 18.75%; positive likelihood ratio: 0.83; negative likelihood ratio: 1.86; and accuracy: 53.28%. Conclusion: Due to the fact that CBCT is not used on a daily basis and Pont’s Index has a relatively high sensitivity (69%) making it suitable to detect patients with a narrow maxilla, assessment of the maxillary deficiency on CBCT can be recommended for cases were the midpalatal suture maturation should be evaluated.

Class III malocclusion is one of the most difficult problems to treat. It has a multifactorial etiology involving both genetic and environmental causes. The dental and skeletal effects of maxillary protraction with a facemask are well documented in several studies. Although incorporation of expansion appliance along with facemask therapy can improve correcting both sagittal and transverse discrepancy of maxilla. The following case shows early treatment of a 9 year old boy with maxillary deficiency using an expansion screw along with facemask. Facemask therapy was followed by fixed orthodontic treatment to settle the occlusion.

Abstract:
ABSTRACT Objectives To assess the effectiveness of bone-anchored maxillary protraction (BAMP) in patients with unilateral cleft lip and palate (UCLP) and whether it was enhanced when preceded by maxillary expansion. Materials and Methods The sample consisted of 28 growing children (9–13 years old) with UCLP and Class III malocclusion. They were divided into two equal groups. In group I, patients were treated with BAMP not preceded by maxillary expansion. In group II, patients were treated with BAMP preceded by maxillary expansion. To assess treatment changes in three dimensions, Cone-beam computed tomography images were taken 1 week after surgical placement of the miniplates (T1) and after 9 months of treatment (T2). Results BAMP produced forward movement of the maxilla in both groups (3.17 mm) and (3.37 mm) respectively, without significant differences between the two groups except for clockwise rotation of the palatal plane in group I (1.60). Conclusions BAMP is an effective treatment modality for correcting midface deficiency in patients with UCLP whether or not maxillary expansion was carried out.

The aim is to evaluate the effects of slow maxillary expansion on maxillary and mandibular arch, using a slow maxillary expander (SME-Leaf Expander) banded on primary second molar. Ninety patients with transverse maxillary deficiency and posterior crossbite were selected. Sixty-nine patients (33 males/36 females; 7.6 ± 1.7 years old) who underwent SME and 21 patients (10 males/11 females; 7.4 ± 1.2 years old) who were treated with rapid maxillary expander (RME). Digital models obtained pre- and post-treatment at appliance removal (9 to 11 months) were processed by means of a 3D scanner (Trios 3, 3Shape D250 laser, Copenhagen, Denmark). Interdental width in both maxilla and mandible were measured with 3 SHAPE Ortho Analyzer. Four Maxillary and four mandibular interdental width were traced and evaluated. The adequate Student’s t-test (dependent or independent) was used to compare intra and intergroups interdental width differences (p < 0.05). The efficacy of the SME was confirmed both on maxillary and mandibular arch. All the maxillary and mandibular interdental widths increased significantly (p < 0.001). The comparison with the RME group showed significant statistical differences between the two treatments with a greater increase in primary first and second intermolar and canine width for the test group (p < 0.001). SME with Leaf Expander produced statistically significant effects for the correction of transverse maxillary deficiencies with a significant indirect effect on the mandibular arch.

Abstract:
The etiology of transverse maxillary deficiency is considered multifactorial, and has a deleterious effect on the bone development of the maxilla and nasal cavities, causing maxillary atresia and posterior crossbite. The objective of this systematic review was to compare in the scientific literature the effectiveness of the maxillary disjunction treated using dental distractor versus bone distractor. A systematic literature review was performed using the Science Direct, Embase, Cochrane Collaboration Library, and PubMed / MEDLINE databases. The search strategy provided a total of 119 studies. After screening by reading the titles and abstracts, seven articles met all the criteria and were included in this systematic review. Studies have shown that the choice of type of orthodontic-orthopedic appliance is directly related to the prior individualized planning of each patient. With regard to patients who are in the development phase, the recommendation is the use of dental maxillary expanders, such as the Hyrax appliance. In addition, it is not recommended to perform rapid maxillary expansion in adult patients, due to the expansion resistance that occurs in the palatine sutures. The treatment of patients with closed median palatine suture must be done by surgically assisted maxillary expansion.

Abstract:
The orthodontic treatment of class III malocclusion with a maxillary deficiency is often treated with maxillary protraction with or without expansion. Skeletal and dental changes have been documented which have combined for the protraction of the maxilla and the correction of the class III malocclusion. Concerning the ideal time to treat a developing class III malocclusion, studies have reported that, although early treatment may be the most effective, face mask therapy can provide a viable option for older children as well. But what about young adults? Can the skeletal and dental changes seen in expansion/facemask therapy in children and adolescents be demonstrated in this age group as well, possibly eliminating the need for orthodontic dental camouflage treatment or orthognathic surgery? A case report is presented of an adult class III malocclusion with a Class III skeletal pattern and maxillary retrusion. Treatment was with nonextraction, comprehensive edgewise mechanics with slow maxillary expansion with a bonded expander and protraction facemask.

ABSTRACT Aim The purpose of this case report is to present the orthodontic, surgical and restorative treatments in the case of an operated cleft lip and palate and severe maxillary deficiency in a 14-year-old female patient. Background Only orthodontic treatment could be inefficient for cleft lip and palate patients characterized with maxillary hypoplasia. Orthodontic and surgical treatment shows sufficient results, especially with severe skeletal deficiency. Case report A cleft lip and palate patient required complex multidisciplinary treatment to preserve health and restore esthetics. Dental leveling and alignment of the maxillary and mandibular teeth were provided before the surgery. Maxillary advancement and clockwise rotation of the maxillary-mandibular complex was applied by a Le Fort 1 osteotomy with two internal distraction devices.

Abstract:
ABSTRACT Objective To evaluate pharyngeal airway and maxillary sinus volumes following symmetric rapid maxillary expansion (RME) and asymmetric rapid maxillary expansion (ARME) treatment using cone-beam computed tomography (CBCT). Materials and Methods The study consisted of 60 patients presenting to the orthodontics clinic with an indication that they required symmetric or asymmetric rapid maxillary expansion treatment. Individuals were included if they were aged 12–15 years and had symmetric (RME group; 14 girls, 16 boys) or asymmetric (ARME group; 16 girls, 14 boys) maxillary deficiency. Maxillary sinus volume (mm3) and pharyngeal airway volume (upper, lower, and total; mm3) were evaluated using CBCT records. The parameters were compared before treatment (T1) and after 3 months in retention (T2). Results All measurements at T2 were increased significantly compared with T1 in the RME group (P &lt; .05). In the ARME group, changes in the lower pharyngeal airway and the nonaffected maxillary sinus volumes (non-affected side of maxillary sinus volumes) were not significant; however, the other measurements increased significantly from T1 to T2 (P &lt; .05). Intergroup comparisons revealed that total pharyngeal airway volume and total maxillary sinus volume changes were significantly greater in the RME group. Conclusions Pharyngeal airway and maxillary sinus volumes increased with both RME and ARME treatment. Both were found to be effective for treating transverse maxillary deficiency.

Abstract:
Maxillary expansion treatments have been used for more than a century to correct maxillary transverse deficiency. Three expansion treatment modalities are used today: rapid maxillary expansion (RME), slow maxillary expansion (SME) and surgically assisted maxillary expansion. Since each treatment modality has advantages and disadvantages, controversy regarding the use of each exists. Rapid Maxillary expansion or palatal expansion as it is sometimes called, occupies unique niche in dentofacial therapy. Rapid Maxillary expansion is a skeletal type of expansion that involves the separation of the mid-palatal suture and movement of the maxillary shelves away from each other.

Abstract:
Objective: Maxillary distraction osteogenesis with the rigid external distraction (RED) system has been used to treat cleft lip and palate (CLP) patients with severe maxillary hypoplasia. We introduce maxillary distraction osteogenesis for CLP patients with skeletal anchorage adapted on a stereolithographic model. Patients: Six maxillary deficiency CLP patients treated according to our CLP treatment protocol had undergone maxillary distraction osteogenesis. Method: In all patients, computed tomography (CT) images were recorded preoperatively, and the data were transferred to a workstation. Three-dimensional skeletal structures were reconstructed with CT data sets, and a stereolithographic model was produced. On the stereolithographic model, miniplates were adapted to the surface of maxilla beside aperture piriforms. The operation performed involved a high Le Fort I osteotomy with pterygomaxillary disjunction. Miniplates were fixed to the maxillary segment with three or four screws and used for anchorage of the RED system. Retraction of the maxillary segment was initiated after 1 week. Results: The accuracy of the stereolithographic models was enough to adapt the miniplates so that there was no need to readjust the plates during surgery. Postoperative cephalometric analysis showed that the direction of the retraction was almost parallel to the palatal plane, and dental compensation did not occur. Conclusions: We performed maxillary distraction osteogenesis with skeletal anchorage adapted on the stereolithographic models. Excellent esthetic outcome and skeletal advancement were achieved without dentoalveolar compensations.

Abstract:
Abstract Objectives To investigate the prevalence of posterior tongue tie in orthodontic patients using numerical and clinical assessment methods in order to identify an association between posterior tongue tie and transverse maxillary deficiency. Materials and methods Seventy-nine participants from an orthodontic clinic were divided into two groups. The first group of 44 patients exhibited a skeletally narrow maxilla and required maxillary skeletal expansion (MSE group) and 35 patients without a transverse discrepancy comprised a control group. Posterior tongue tie was examined by the Kotlow tongue tie classification, tongue range of motion ratio (TRMR) and via a clinical assessment. The prevalence of posterior tongue tie was compared between the two groups. Results There was no significant difference in the level of the Kotlow classification grade between the two groups (p > 0.05) and the overall majority was diagnosed as normal. However, a higher proportion of posterior tongue tie was found in the MSE group than in the control group by clinical assessment (MSE group, 72.7%; control group, 42.9%; p = 0.005). The proportion of TRMR grade 2 was also higher in the MSE group than in the control group (p = 0.001). Of the subjects diagnosed with posterior tongue tie by clinical findings, approximately 94% showed TRMR grades 2 or 3. Conclusions A clinical assessment of posterior tongue tie was found to be simple and accurate, whereas a numerical assessment alone provided diagnostic difficulty. Considering the high prevalence of observed posterior tongue tie in the MSE group, there was a significant association between posterior tongue tie and transverse maxillary deficiency.

Abstract:
Class III skeletal malocclusion may present several etiologies, among which maxillary deficiency is the most frequent. Bone discrepancy may have an unfavorable impact on esthetics, which is frequently aggravated by the presence of accentuated facial asymmetries. This type of malocclusion is usually treated with association of Orthodontics and orthognathic surgery for correction of occlusion and facial esthetics. This report presents the treatment of a patient aged 15 years and 1 month with Class III skeletal malocclusion, having narrow maxilla, posterior open bite on the left side, anterior crossbite and unilateral posterior crossbite, accentuated negative dentoalveolar discrepancy in the maxillary arch, and maxillary and mandibular midline shift. Clinical examination also revealed maxillary hypoplasia, increased lower one third of the face, concave bone and facial profiles and facial asymmetry with mandibular deviation to the left side. The treatment was performed in three phases: presurgical orthodontic preparation, orthognathic surgery and orthodontic finishing. In reviewing the patient's final records, the major goals set at the beginning of treatment were successfully achieved, providing the patient with adequate masticatory function and pleasant facial esthetics.

Abstract:
The difficulty of management of a transverse maxillary hypoplasia is to choose the right treatment and the appropriate tools. When transverse maxillary insufficient is associated to sagittal and/or vertical discrepancies in adults, the gold standard treatment is a surgical procedure combined with orthodontic treatment. The surgical procedure can be done in 1 or 2 stages. If the patient chooses a lingual orthodontic technique, the tools for expansion and the stabilization of expansion are not simple to use. The aim of this article is to report the case of a 25-year-old male patient, referred to our cabinet for skeletal Class-III malocclusion associated with laterognathism and transverse maxillary deficiency. The patient underwent one-stage surgery. He choose to be treated by a lingual orthodontic technique, we used the FKS® disjunction device.

Abstract:
Over the last 15 years, cleft lip and palate (CLP) patients with maxillary deficiency in the care of the Bergen CLP Team have received interceptive orthopedic treatment to correct anterior and posterior crossbites during the deciduous and mixed dentition periods. The present study comprises 72 subjects of various cleft types with anterior crossbite, treated to an acceptable positive overjet by maxillary protraction using a facial mask (Delaire). Lateral cephalograms were taken immediately before and after the active treatment periods. Individuals exhibiting a favorable (fair) skeletal response to the protraction were compared with those who revealed little, (poor) skeletal response. Two cephalometric variables were chosen for the evaluation of the sagittal skeletal treatment changes: (1) the sagittal maxillomandibular change (change of angle ss-n-sm [ANB]); and (2) the forward movement of the maxilla (change of distance NSP-maxp), where maxp (maxillary point) represents the anterior contour of maxilla and NSP is the perpendicular to the naslon-sella-line (NSL) through sella. A numerical change greater than or equal to the value 1.5 (degrees or mm, respectively) was classified as fair versus poor response revealing a change less than 1.5. Fair-response (favorable response) of sagittal maxillomandibular change was found in 63 % of the cases (mean increase of angle ANB was 3.3 degrees), more often when protraction started early. The length of maxilla was increased, the skeletal maxilla was moved forward 1.8 mm, the upper dentition advanced 3.6 mm, the occlusal line was clockwise rotated, and the anterior face height was increased. Similarly, fair-response of forward movement of maxilla was found in 44% of the cases (mean increase of distance NSP-maxp was 2.4 mm), more often when protraction was started early and after long treatment duration. The maxillary prognathism increased 1.8 degrees, the angle ANB increased 3 degrees, the length of maxilla increased 1.5 mm, and the upper dentition was advanced 3.7 mm. The anterior face height increased with counterclockwise rotation of the nasal line, whereas the occlusal line was clockwise rotated. A paired fair-response of both skeletal maxillomandibular change and skeletal forward movement of maxilla was found in 35% of the cases. During protraction the mean increase of maxillary prognathism was 2.1 degrees, the maxilla moved forward 3.1 mm, the maxillary dentition advanced 4.3 mm, the maxillary length increased 1.9 mm, the ANB angle increased 3.7 degrees, and the lower anterior facial height increased 3.4 mm.

Abstract:
Abstract Introduction Anteroposterior maxillary deficiency can be associated with a decrease of upper airway volume. Maxillary advancement can improve the upper airway space. Aim To correlate cephalometric (2D) and volumetric (3D) measurements of the upper airway in class III patients treated by maxillary advancement. Material and method This retrospective transversal study was performed in ten adult patients submitted to maxillary advancement for correction of class III deformity secondary to maxillary anteroposterior deficiency. The Cone beam tomography files included in the medical records were used: (T1) pre-operative and (T2) 6 to 8 months postoperative. The DICOM files were imported and reconstructed for volumetric and cephalometric evaluation of the upper airway, as divided into nasopharynx, oropharynx and hypopharynx (Arnett & Gunson FAB Surgery). Result Age ranged from 26 to 55 years with a mean of 36.3±9.2 years. There were no statistically significant differences for cephalometric and volumetric parameters of the three pharyngeal regions between T1 and T2 periods. This was due to the small amount of maxillary advancement necessary to correct the maxillary deformity in the studied patients (4.7±1.89mm). The correlation between area and volume was not statistically significant only for preoperative measurements of the nasopharynx (r=0.30, p=0.40). It was significant for the other regions and evaluation periods (p<0.05). Conclusion Small maxillary advancements do not result in significant increases in airway dimensions.

Objective The aim of this study was to evaluate skeletal and dentoalveolar changes before and after skeletal anchorage-assisted rapid palatal expansion in young adults by cone beam computed tomography. Materials and Methods This pilot study included ten patients with a mean age of 21.5 years with maxillary transverse deficiency treated with the skeletal expander. Three dimensional evaluation of the changes before and after expansion was evaluated with Cone Beam CT. Statistical analysis was performed using paired t-test. Results Skeletal expander produced an increase in maxillary transverse dimension at the skeletal, alveolar, and dental level. The maximum expansion was at the level of dentition, and the least amount of expansion was at the level of the frontonasal suture. There was also evidence of sutural divergence and buccal tipping. Conclusion The maxillary skeletal expander is an effective method for correction of maxillary transverse deficiency without surgery in adults.

ABSTRACT Objective: To assess the volumetric changes that occur in the nasomaxillary complex of mouth-breathing patients with transverse maxillary deficiency subjected to rapid maxillary expansion (RME). Methods: This was a controlled, prospective intervention study involving 38 mouth-breathing patients presenting with transverse maxillary deficiency, regardless of malocclusion type or race. Twenty-three of them comprised the experimental group, which was composed of 11 (47.8%) boys, and 12 (52.2%) girls, with a mean age of 9.6 years, ranging from 6.4 to 14.2 years and standard deviation of 2.3 years; and 15 of them comprised the control group, composed of 9 (60%) boys and 6 (40%) girls with an mean age of 10.5 years, ranging from 8.0 to 13.6 years, and standard deviation of 1.9 years. All patients were scanned (CT) according to a standard protocol: Initial CT (T1), and CT three months thereafter (T2), and the patients in the experimental group were treated with RME using a Hyrax expander for the correction of maxillary deficiency during the T1-T2 interval. The CT scans were manipulated using Dolphin® Imaging version 11.7 software for total and partial volumetric assessment of the nasomaxillary complex. Results: The results revealed that in the experimental group there was a significant increase in the size of the structures of interest compared to the control group, both in general aspect and in specific regions. Conclusions: Rapid maxillary expansion (RME) provided a significant expansion in all the structures of the nasomaxillary complex (nasal cavity, oropharynx, right and left maxillary sinuses).

Abstract:
AbstractProgressive premaxillary retrusion is a common sequela of the facial aging process. In most cases, this manifests with central maxillary recession. Central maxillary insufficiency is also commonly encountered within certain ethnic communities, or in cleft lip nasal deformity, and may represent a challenge for the plastic and reconstructive surgeon attempting correction in the setting of facial contouring, rhinoplasty, or reconstruction following oncologic resection or trauma. Aesthetically, premaxillary retrusion may be coincident with an acute nasolabial angle and ptotic nasal tip. Minor deformities may be addressed with use of either alloplastic implants, autogenous tissue, lipotransfer, or injectable filler. Larger composite defects may require reconstruction with implementation of free tissue transfer. Herein, we describe techniques that aim to augment, or reconstruct, the premaxillary region in the context of nasal deformity, osseous resorption, or composite maxillofacial defects.

Abstract:
Since 1977 cleft lip and palate (CLP) patients with maxillary deficiency have received an interceptive orthopedic treatment consisting of (a) transverse expansion, (b) protraction, and (c) fixed retention. Ideally the treatment should be completed early enough to permit spontaneous eruption of the maxillary permanent incisors into normal occlusion without orthodontic intervention. The early transverse expansion considerably increases space so that unerupted malpositioned incisors spread out spontaneously, creating optimal conditions for eruption and root formation. Dental diagnosis in the cleft areas is made easier. Posterior crossbites in 112 CLP patients were expanded with a modified quad-helix appliance cemented with four bands in the deciduous or mixed dentition. Intercanine widening was about 3 mm per month regardless of cleft type. Several authors have claimed that transverse expansion of the upper jaw will increase sagittal overjet. Other authors have not found such an effect. The sagittal effect on the maxilla was studied in 68 CLP patients who had received transverse expansion. Analysis of the lateral cephalograms revealed no significant sagittal dentofacial maxillary treatment effects involving forward movement of maxilla, but a downward clockwise rotation of the mandible was found.

Abstract:
The purpose of this study was to report a case with complete unilateral cleft lip and palate (CLP) treated with bone anchored maxillary protraction (BAMP) in miniplates followed up until the end of facial growth. A 7-year-old girl with complete left side CLP started the orthodontic treatment in a rehabilitation center. She presented a Class III skeletal pattern due to maxillary deficiency, a GOSLON 4 sagittal interarch relationship, a negative overjet of 1.5mm and agenesis of left upper lateral incisor. In the mixed dentition, the patient was submitted to rapid maxillary expansion followed by the secondary alveolar bone grafting procedure. At 12y 3m two miniplates were installed in the maxilla and two in the mandible with BAMP therapy. The patient was instructed to use full time Class III elastics with force of 250g/side together with a bite lifting plate in the upper arch. BAMP therapy duration was 19 months leading to a positive overjet and GOSLON 1 sagittal interarch relationship. The cephalometric analysis demonstrated a mild maxilla advancement. Class III elastics started to be used only at night as an active retention concomitantly with Phase II orthodontic treatment. Compensatory corrective orthodontic treatment established adequate occlusion between the dental arches with significant improvement of facial aesthetics after the intervention. Le Fort 1 surgery with maxillary advancement was not necessary.

Abstract:
The abnormal growth of the craniofacial bone leads to skeletal and dental defects, which result in the presence of malocclusions. Not all causes of malocclusion have been explained. In the development of skeletal abnormalities, attention is paid to general deficiencies, including of vitamin D3 (VD3), which causes rickets. Its chronic deficiency may contribute to skeletal malocclusion. The aim of the study was to assess the impact of VD3 deficiency on the development of malocclusions. The examination consisted of a medical interview, oral examination, an alginate impression and radiological imaging, orthodontic assessment, and taking a venous blood sample for VD3 level testing. In about 42.1% of patients, the presence of a skeletal defect was found, and in 46.5% of patients, dentoalveolar malocclusion. The most common defect was transverse constriction of the maxilla with a narrow upper arch (30.7%). The concentration of vitamin 25 (OH) D in the study group was on average 23.6 ± 10.5 (ng/mL). VD3 deficiency was found in 86 subjects (75.4%). Our research showed that VD3 deficiency could be one of an important factor influencing maxillary development. Patients had a greater risk of a narrowed upper arch (OR = 4.94), crowding (OR = 4.94) and crossbite (OR = 6.16). Thus, there was a link between the deficiency of this hormone and the underdevelopment of the maxilla.

Abstract:
The orthodontic treatment of Class III malocclusion with a maxillary deficiency is often treated with maxillary protraction either with or without maxillary expansion. The routine procedure for rapid maxillary expansion includes banding on first premolars/first deciduous molars and the permanent first molars. However in some patients who are esthetically very conscious, banding of the first premolar would not be a good esthetic option. So for such circumstances we have designed a modified hyrax splint, which does not need the first premolars to be banded.
