Abstract:

Satisfactory restoration in a patient with a partially edentulous situation can be challenging especially when unilateral or bilateral posterior segment of teeth is missing. Successful restoration can be done with various conventional and contemporary treatment options. One such treatment modality is attachment-retained cast partial dentures. This paper describes a case report of a patient with maxillary bilateral distal extension edentulous span restored with a cast partial denture having an extracoronal castable precision attachment (RHEIN 83 OT CAP attachments system).

Abstract:

ABSTRACT Aim To investigate the importance of attachment types on the retention loss of extracoronal attachment-retained removable partial dentures depending on the usage period. Materials and methods In order to observe the retention loss of 5 different attachments (OT Strategy, OT Strategy-metal protected, Vario-stud-snap and Vario-soft 3 and ERA-RV) over time, attachment-retained partial dentures representing Kennedy II mod. I case were placed in a custom-made, retention test machine. For each minute, eight separating and joining movements were performed and retention values (Newton) of the attachments were recorded by computer. The retention tests implemented in 540,1080 and 2160 cycles. The data were evaluated statistically according to the two-way ANOVA and Tukey parametrical tests. Results The slide type attachment providing the best retention force was observed to be the most worn out by this process (p < 0.01) while the ball type attachments, which typically have the lesser retention force, showed less retention loss (p < 0.01). Conclusion It can be concluded that the retention attributes of the attachment-retained dentures were affected by the specific type of precision attachment as well as the usage period. Clinical significance Precision attachments with ball-type plastic matrices may be recommended for the clinical use due to their retention stability over time.

Abstract:

Among the numerous techniques of oral rehabilitation, precision attachments are considered as a good treatment option in removable (RPD) as well as fixed partial dentures (FPD). Precision attachments enhance patient’s self-confidence and selfimage as they help in facilitating aesthetic, functional and retentive replacement of teeth that are missing in the oral cavity. They can improve the aesthetics by eliminating the clasp assembly in cast partial dentures (CPD). This particular case report explains the treatment sequence and approach for the utilisation of attachments in a Kennedy Class 2 situation. A successful removable partial denture includes a precise diagnosis with meticulous treatment planning. However, re-establishment of partially edentulous arch is particularly challenging in distal extension situations classified as Kennedy’s class 1 or 2 conditions.1 In such clinical cases, where a fixed prosthesis cannot be fabricated, a prosthodontist often suggests an implant retained prosthesis that is not routinely possible because of the insufficient available bone width and height.2 Thus to ensure functional and aesthetic substitution of lost teeth, an attachment secured RPD can be considered as a good treatment option in such cases. Attachments are constructed in a ready to place form (pre-fabricated) known as precision attachments. Another one is semi precision attachment where the segments have to be constructed by dentists or dental technicians because it requires casting for incorporating into fixed unit of restoration.3 Hence precision attachments are considered as possible alternatives when patients demand for a fixed restoration in distal extension cases. Various extra coronal attachments are available and used in distal extension cases. Preci-Sagix is considered as an ideal extra coronal attachment for removable partial dentures and also in over denture cases. It is accessible in two sizes, 1.7 mm mini or 2.2 mm standard and is selected according to the permitted space. The male component is available in three varieties, a plastic castable pattern (any hard alloy), cast to no prax (only non-precious alloy) and a threaded male and base ring (2.2 mm size only).4 These attachments produce vertical, horizontal and rotational movements during its function which supports the prosthesis by transferring harmful forces from the abutments to the supporting structures by its passive movement, which helps in the rehabilitation of distal extension cases.5 This case report explains restoration of partially edentulous arch by incorporating a Preci Sagix attachment in mandibular cast partial denture retained by a six-unit FPD and a maxillary conventional cast partial denture.

Abstract:

Successful restoration can be done with plenty of contemporary and conventional treatment planning. Attachment retained partial dentures are one such kind of treatment modality in prosthodontics. Studies have also demonstrated that precision-attachment partials last longer, wear less, need fewer adjustments, look better, work better, less destructive, protect abutment teeth, and are easier to clean. In this case report patients functional and aesthetic expectations were met by using a combination of Porcelain fused to metal (PFM) restorations and semi-precision attachments.

Abstract:

In the case of losing many teeth and the residual teeth have short clinical crown, design of the denture may hybriddenture. Hybrid denture is a removable partial denture with metal frame which have retention in the form ofprecision attachment. In short clinical crown, placement of crowns and the use of traction can be a problem,because there is no or lack of retention. In the manufacture of hybrid denture with precision attachment retention,using abutment with short clinical crowns is contraindicated. But in some literatures mentioned that the rest of theclinical crown height of not less than 2 mm can still be used as an abutment, but the abutments must be modified,such as making a longer preparation towards cervical edge. In several studies and literature, it is mentioned that toimprove the retention of the crown, the axial wall of abutment must be 4-6°. This article is aimed to report the clinical success of using the hybrid denture on abutment teeth which have short clinical crowns in a patient woman

Abstract:

Retention for a denture on a ramus frame implant is usually less satisfactory. The friction between the frame and denture is not reliable. Locking-type attachments require manual dexterity, which could be a problem for many patients. This article presents a technique of cementing the stud-type attachments to the ramus frame to convert the retention mechanism from one that uses the friction between the acrylic resin and ramus frame to a conventional resilient precision attachment. The retention can also be adjusted by changing the nylon inserts.

Abstract:

BACKGROUND: Utilization of attachments in a removable partial denture is highly essential not only as a line of treatment but also as it has a remarkable impact on the denture’s durability during the function. The attachment should act as a stress breaking system preserving the abutment teeth. AIM: This consideration aimed to verify the convention of polyether ether ketone (PEEK) material as an attachment. MATERIAL AND METHODS: Four groups of different materials for both attachments and partial denture framework were fabricated and tested using strain gauges to compare between them according to the strains originated around both the abutment teeth and edentulous area. RESULTS: PEEK material is one of the esthetic materials used for fabrication of the framework of the RPD. On using it as a precision attachement is shows favorable stress distribution decreasing the strains around the abutment teeth and the alveolar ridge especially distal to the abutment teeth that was significantly reduced in comparison with the other treatment options. CONCLUSION: Utilization of PEEK material as both an attachment and framework decline the strains performed around the abutment teeth and over the edentulous ridge.

Abstract:

Use of attachment in providing retention to removable prosthesis is an old treatment modality with better success. It highly improves the comfort, aesthetic, function, and patient satisfaction, especially in the patients with long span edentulism where implants and fixed partial denture (FPD) are not indicated and cast partial dentures are barely satisfactory. Proper diagnosis and treatment planning is necessary for selection of appropriate attachment type. A comprehensive evaluation, multi-disciplinary approach and sequential treatment planning is needed for long-term successful outcome. This case report describes the use of an extra coronal semi-precision attachment to enhance retention of removable prosthesis.

Abstract:

Teeth loss is a traumatic experience. It disturbs the total integrity of the masticatory system. Its successful rehabilitation should address a range of biomechanical problems, tolerances, and perceptions. Precision attachment-supported over Dentures with two teeth retained in canine region is a predictable treatment option in edentulous mandible rather than conventional complete denture as it offers increased retention, stability, comfort, bone preservation, maintenance of proproception and patient compliance. This study was carried out to determine patient satisfaction with precision attachment-supported overdentures and conventional overdenture and its impact on the treatment outcome. Material & Methods: Twenty(20) edentulous patients were randomly divided into two groups to receive precision attachment -supported overdentures and conventional overdenture in mandibular arch. Questionnaires were given to the patient after treatment at 6 and 12months interval. Data collected were statistically analyzed. Results: Results obtained from this study show that patients with precision attachment -supported overdentures were more satisfied with the treatment outcome, and there was a significant difference in patient satisfaction between the two groups.

Abstract:

This paper aims to compare, in vitro, the biomechanical properties of an overdenture retained by two bar-retained implants and an overdenture retained by two bar-retained implants with ball attachments. An edentulous mandible model was prepared for the study based on the FRASACO mold with two implants. In the first system, the “rider” type (PRECI-HORIX, CEKA) retention structure and the complete mandibular denture with the matrix were made. In the second system, the “rider” type retention suprastructure was also used. In the distal part, (CEKA) clips were placed symmetrically, and a complete mandibular denture, together with the matrix on the bar, and the clip patrices were made. A numerical model was developed for each system where all elements were positioned and related to geometric relations, as in reality. The FEA analysis (finite element analysis) was carried out for seven types of loads: with vertical forces of 20, 50, and 100 N and oblique forces of 20 and 50 N acting on individual teeth of the denture, namely central incisor, canine, and first molar. Displacements, stresses, and deformations within the systems were investigated. Maximum denture displacement in the first system was 0.7 mm. Maximum bar stress amounted to 27.528 MPa, and implant stress to 23.16 MPa. Maximum denture displacement in the second system was 0.6 mm. Maximum bar stress amounted to 578.6 MPa, that of clips was 136.99 MPa, and that of implants was 51.418 MPa. Clips cause smaller displacement of the overdenture when it is loaded but generate higher stress within the precision elements and implants compared to a denture retained only by a bar. Regardless of the shape of the precision element, small deformations occur that mainly affect the mucosa and the matrix.

Abstract:

Background: Losing posterior teeth for a long time would occasionally lead to the sharpening of alveolar process. The removable partial denture usually have problems when used during mastication, because of the pressure on the mucosa under the alveolar ridge. Purpose: The purpose of this case report was to manage patients with sharp mandibular alveolar process by wearing hybrid prosthesis with extra coronal precision attachment retention and soft liner on the surface base beneath the removable partial denture. Case: A 76 years old woman visited the Prosthodontic Clinic Faculty of Dentistry Airlangga University. The patient had a long span bridge on the upper jaw and a free end acrylic removable partial denture on the lower jaw. She was having problems with mastication. The patient did not wear her lower denture because of the discomfort with it during mastication. Hence, she would like to replace it with a new removable partial denture. Case management: The patient was treated by wearing a hybrid prosthesis with extra coronal precision attachment on the lower jaw. Soft liner was applied on the surface of the removable partial denture. Hybrid prosthesis is a complex denture consisting of removable partial denture and fixed bridge. Conclusion: It concluded that after restoration, the patient had no problems with sharp alveolar process with her new denture, and she was able to masticate well.Latar belakang: Kehilangan geligi posterior dapat menimbulkan processus alveolaris tajam. Gigi tiruan sebagian lepasan mempunyai masalah selama pengunyahan karena adanya tekanan di mukosa di bawah alveolar ridge. Tujuan: Tujuan laporan kasus ini adalah untuk menjelaskan cara menangani pasien yang mempunyai prosesus alveolaris yang tajam di rahang bawah dengan dibuatkan protesis hybrid dengan daya tahan extra coronal precision attachment dan soft liner di permukaan bawah basis gigi tiruan sebagian lepasan. Kasus: Pasien wanita berumur 76 tahun datang di klinik Prostodosia Fakultas Kedokteran Gigi Universitas Airlangga. Pasien memakai gigi tiruan lekat rentang panjang di rahang atas dan gigi tiruan sebagian lepasan akrilik free end di rahang bawah, pasien mengalami masalah waktu mengunyah. Pasien tidak memakai gigitiruan lepasan rahang bawahnya karena tidak nyaman dipakai, dan pasien menginginkan pembuatan gigi tiruan lepasan rahang bawah yang baru. Tatalaksana kasus: Pada pasien ini dilakukan pembuatan Hybrid Prosthesis dengan daya tahan berupa extra coronal attachment di rahang bawah dan penggunaan bahan pelapis lunak yang diaplikasikan pada basis gigi tiruan lepasan nya. Hybrid prosthesis adalah gigi tiruan himpunan yang terdiri dari gigi tiruan lepasan dan gigi tiruan lekat. Kesimpulan: Hasil perawatan menunjukkan setelah mengganti gigi tiruan dengan gigi tiruan sebagian lepasan yang baru, pasien tidak mempunyai masalah dengan gigi tiruan yang baru akibat processus alveolaris yang tajam dan pasien dapat mengunyah dengan baik.

Abstract:

Various precision attachment systems are available for tooth supported overdenture treatment modality. The objective of all the systems is to provide retention and support for the overdenture. Retention of a mandibular denture can be achieved by natural tooth-retained with bar and stud attachment in anterior region. A simple and cost effective treatment for a more complex implant overdenture is the concept of conventional tooth-retained overdentures. The present clinical report describes a patient treated with customized hader bar with coffee straw in mandibular tooth-borne overdenture.

Abstract:

Oral rehabilitation of partially edentulous arches requires careful treatment planning before any prosthodontic intervention. The connection of the metal framework of fixed (fixed dental prosthesis (FPD)) and removable partial denture using adhesive attachments is a good alternative prosthetic option when solely fixed prosthesis (FPD or implant) cannot be used due to anatomical limitation. Attachments are the tiny interlocking devices that act as a hybrid link to join removable prosthesis to the abutment and direct the masticatory forces along the long axis of the abutment. This joint acts as a non-rigid stress breaker, which helps in distributing the occlusal load. Precision and semiprecision attachment have always been bordered by an aura of mystery due to technique sensitive procedure and lack of knowledge. The following case describes a combined contemporary and conventional approach and treatment sequence with the use of attachments for the rehabilitation of partially edentulous arches.

Abstract:

PURPOSE: The aim of this study was to evaluate biting force of patients with unilateral mandibular distal extension area treated with two different designs of the removable partial denture (RPD), conventional RPD, and new design of extracoronal castable precision attachment (OT Unilateral attachment). MATERIALS AND METHODS: This study was conducted on 16 patients with unilateral mandibular distal extension area with the second premolar is the last abutment teeth. The patients were divided into two equal groups, Group I received conventional RPD, which provides cross arch stabilization and a double Aker clasp was fabricated. Group II received new design of extracoronal castable precision attachment (OT Unilateral attachment). Evaluation of biting force by loadstar sensor, patients of both groups were evaluated at the time of prosthesis insertion, 3, 6, and 1 year later. Statistical analysis performing one-way analysis of variance followed by Tukey’s post hoc test to compare between all follow-up periods within each group, comparison between two groups regarding each follow-up period was performed by independent t-test. RESULTS: Both treatments yielded better after-treatment summary when compared with the baseline; however, better results were obtained and showed a statistically significant increase in Group II (OT unilateral design), especially after 3, 6 months, and 1 year later. CONCLUSION: From the results of this study, it was concluded that: It is preferable to use the new design of extracoronal castable precision attachment (OT unilateral) being simpler, more comfortable to the patients and give high masticatory efficiency in the form of biting force than conventional RPD.

Abstract:

The main aim of prosthetic dentistry is restoring the form, function, comfort and appearance of the patient by the placement of a prosthesis replacing the missing teeth and contiguous tissues.1 Various prosthetic options for partially edentulous patients include an interim removable partial denture (RPD) to a cast partial denture, a fixed dental prosthesis (FDP), and a more implant-retained prosthesis. However, FDP and implant-retained prosthesis are not always feasible, particularly in patients with excessive residual ridge resorption and jaw defects due to trauma and / or surgical ablation. In such a situation, a dentist may resort to another option of fixed-RPD prosthesis, to restore the defective hard and soft tissues to achieve natural aesthetics, phonetics, comfort, and better hygiene. This hybrid prosthesis fulfils the objectives of the rehabilitation such as support, stability, and retention characteristics similar to a fixed prosthesis and aesthetics and hygiene maintenance of a removable prosthesis.2,3,4,5 Any prosthesis designed or fabricated should be based on the prosthetic principles of support, stability, retention, and preservation of remaining structures.1 From the patient's perspective, retention is one of the important factors for its acceptability. These retentive options range from simple bar and clip attachments to more sophisticated spark erosion overdentures.6,7 Spark erosion prosthesis is technique sensitive, bulky, and requires expensive equipment.6,7 On the other hand, precision attachments provide better vertical support and stimulation to the underlying tissue through intermittent vertical massage.8 Treatment with a hybrid denture is an affordable choice to fulfil the patient's aesthetic demands along with providing a good prognosis for the prosthesis and preservation of the remaining dentition. This article presents two case reports of prosthodontic rehabilitation of a patient with mandibular defects using an attachment-retained fixed-removable hybrid prosthesis.

Abstract:

Purpose: To compare the effect of two treatment options in mandibular Kennedy class I cases regarding oral health related quality of life (OHRQoL) and the biting force, removable partial dentures retained by either precision attachment (PA-RPD) or clasps (C-RPD)Materials and methods: The study included 32 partially edentulous patients which 16 patients received PA-RPD (OT Cap Attachment) and 16 patients received C-RPD. All the patients in both groups were asked to fill the OHRQoL questionnaire after 1 week (baseline), 3 months, 6 months and 12 months after prosthesis insertion. Biting force was measured using the i-load Star Sensor one week, 3 months, 6 months and 1 year after partial denture insertion for all patients in both groups. Statistical analysis comprised Mann Whitney U test, Friedman’s test, Dunn’s test and Chi-square test.Results: The results of OHRQoL revealed that at the baseline, 3 months and 6 months the PA-RPD showed statistically significant lower mean total OHIP-14 score than the C-RPD. However, after 12 Monthes , there was no statistically significant difference between total OHIP-14 scores in the two groups. Concerning the biting force there was no statistically significant difference between the two groups.Conclusion: Within the limitations of this study it was concluded that the OHRQoL of both the PA-RPD and the C-RPD was comparable after 12 months. Similarly the biting force was the same for both treatment options.

ABSTRACT Residual ridge deformity after tooth loss is an expected outcome. The treatment of a patient with a history of trauma with loss of teeth and ridge defect is a significant challenge. This article presents a case of Seibert's class III ridge defect in the maxillary anterior region, which was treated with a fixed-removable system, the Andrew's bridge, for economical and time constraints. It requires a castable bar and sleeve attachment, which provides precision and retention while seating. It is primarily indicated where abutments are capable of supporting a fixed partial denture, but residual ridge shows severe loss. How to cite this article Ram SM, Nigam AA, Nadgere JB, Shah NP.

Abstract:

Extracoronal precision attachment provides an available solution for complicated periodontal conditions in patients with dentistry defect. The mandibular Kennedy I dentition defect refers to the dentition defect at bilateral free-end molars. The bilateral nearby teeth are used as the abutment of extracoronal precision attachment to offer supporting forces. However, it is difficult to choose the quantities of abutments for patients with various periodontal conditions. The aim of this study is to suggest quantities of abutments based on stress distributions under various periodontal conditions for patients with mandibular Kennedy I dentition defect. Models were constructed from computed tomography, and they were assembled and analyzed in ANSYS. Seven models were used in our study based on different periodontal conditions and quantities of abutments (three models in healthy periodontal condition using single, double and triple abutment(s) restorations, two models with one absorbed abutment using double and triple abutments restorations and two models with two absorbed abutments using double and triple abutments restorations). The degree of absorbed abutments was 1/3. The mandible and other structures were considered as an orthotropic material and isotropic materials, respectively. Loads and boundary conditions corresponded to the realistic occlusion. Poor periodontal conditions enlarge the stress on abutments and surrounding structures. In addition, the increase in quantity of abutments causes the decrease and distribution of stress to differ. Different periodontal conditions require different quantities of abutments for recommendation in rehabilitation. The double abutments restoration is suitable for patients without absorbed abutment. The triple abutments restoration should be considered for patients with only one absorbed abutment. If more than two absorbed abutments exist, the extracoronal attachment denture restoration is not recommended for patients.

Abstract:

<p class="abstract">Oral rehabilitation of bilateral mandibular edentulous posterior segments becomes even more difficult if patient had severe deep bite in natural dentition. This case report demonstrates the intelligent way of managing severe deep-bite by adapting multi-disciplinary approach. Involved steps are: Mandibular subapical osteotomy of mandibular anterior segment to lower down the fragment; secondly, the maxillary anteriors were done with crown lengthening followed by decreased incisal display and thirdly by restoring vertical dimension of occlusion by replacement of missing posterior teeth. The addition of surgical intervention (anterior mandibular osteotomy) in the present case has found to be effective and quick adjunctive in achieving functional improvement in occlusion by reducing anterior teeth overlap (deep bite), by decreasing incisal guidance steepness and esthetic display of anterior teeth. Bilateral edentulous situation was managed by precision attachment retained cast partial denture. A satisfactory functional and esthetic result was obtained.</p>

Abstract:

Significant reconstruction of damaged teeth requires a great deal of new and traditional treatment methods, and the design of attachment retained removable partial dentures is one such therapeutic approach in prosthodontics. Customized semi-precision fittings with partial dentures provide strength and enhanced aesthetics in situations with limited space. The objective of the study was to determine the knowledge and understanding of precision attachments amongst dental students. A descriptive survey was conducted among undergraduate and postgraduate dental students using a structured questionnaire. The questionnaire gathered information on the respondent's knowledge regarding the use of precision attachments among dental practitioners in dentistry. Out of the 100 students,60% of them believed that based on the geometric configuration and design of the attachment precision attachments can be classified as the key lock, 20% believed that they were classified as latch type attachments and the rest 20% believed that they were classified as ball and socket attachment. Out of the 100 students who took the survey, 80% believed that the advantages of using precision attachments were all except increasing the stress to abutment and 20% believed that the advantages were all except decreasing torsional forces. All the students who had taken part in the survey had moderate knowledge about the use of precision attachments in dentistry. More intensive educational and awareness initiatives should be undertaken to increase the awareness levels about precision attachments among dental students.

Abstract:

Abstract Passively retained precision attachment partial dentures have been used successfully on natural tooth abutments since the 1920s. However, the dental profession has not advocated their use with implant abutments. When used in the passive manner that has proven successful on natural tooth abutments, precision attachment cases on implant abutments can be an excellent treatment option. This type of case has been used successfully for more than 17 years and offers tremendous advantages over the conventional overdenture approach to removal restorations on implant abutments.

Abstract:

ABSTRACTThe majority of maxillary defects can be rehabilitated with conventional simple obturator prosthesis. However, inadequate retention, stability and support may be associated with the use of an obturator. Precision attachments have been used to retain obturators for some time. The use of precision attachments in a dentate maxillectomy patient can yield significant functional improvement while maintaining the obturator’s aesthetic advantages. This clinical report describes the prosthetic rehabilitation of two maxillary defects with an obturator retained using extracoronal resilient precision attachments. (Eur J Dent 2012;6:212-217)

Abstract:

ABSTRACT This case series describes prosthodontic management of seven cleft-lip-and-palate patients with different cleft deformities, gender and age. Patients were rehabilitated using conventional prosthesis. Five patients in whose maxillary arch was orthodontically expanded were treated with a combination of fixed and removable partial dentures with precision attachments. Two patients, who did not maxillary collapse were treated with metal-ceramic fixed-partial-dentures. All patients were followed up to two years. When there are limitations for secondary bone- grafting and implants, conventional approaches provide good physiologic, functional and esthetic outcomes with care taken to prevent maxillary relapse in treating these patients.

Abstract:

Aim: To compare new design implant-supported removable partial dentures retained with anterior fixed prosthesis with a conventional locater and bar attached implant overdenture prostheses retained by two or four implants via photoelastic stress analysis. Materials and Methods: Seven edentulous mandibuler acryclic models prepared and divided into two main groups; two to four implant models, subgroup separation as stated; for two implant models overdenture with locator attachment, crown design retained removable prosthesis with clasp retention, bridge design retained removable prosthesis with clasp retention, bridge design retained removable prosthesis with precision attachment retention; and for four implant models prosthesis with bar attachment overdenture, fixed bridge design retained removable prosthesis with clasp retention, fixed retained removable prosthesis with precision attachment retention. A 300 N load was applied to the first premolars. Photoelastic stress analysis method that is a specific method concerning stress visualization, and does not require statistical analysis, was used. The stress distributions were seen in optically using a poloriscope. Results: In the models with two implant-retained removable partial dentures, the stress distribution was found to be lower than that with the four implant-retained removable partial dentures. Nonsplinted implants caused high stress around the distal implant on the loading side. Conclusion: The stress loads were transmitted to other implants by splinting. Implant-supported removable partial dentures with an anterior fixed prosthetic design show lower stress distributions compared with bar retained prosthesis. These dentures appear to be advantageous in terms of stress transmission.

Abstract:

Abstract Objectives This retrospective clinical study investigates the frequency of biological and technical complications in patients rehabilitated by natural root-retained overdentures (RODs) with cast post-and-cores (root caps) wearing precision attachments and analyses factors influencing complication rates (e.g. oral hygiene routines). Materials and methods Patients formerly treated with RODs were invited for a cost-free clinical visit to evaluate their intraoral status. Furthermore, they were interviewed and patient records were screened for complications occurring since denture delivery. Statistical models include descriptive analyses, Fisher’s exact test, odds ratios, and a multivariate regression model. Results A total of 114 patients wearing 128 RODs with a total of 280 abutment teeth were evaluated (mean service time: 7.9 years). Technical complications occurred in 68.8% of the RODs, with matrix loosening being the most frequent complication (50.1%). Biological complications occurred in 53.9% of all RODs, with the presence of denture stomatitis being the most common biological complication (38.3%). The presence of denture stomatitis was significantly higher in the maxilla relative to the mandible (p = 0.0029), in subjects cleaning their dentures less than twice a day (p < 0.001), in subjects regularly using CHX-containing products (p = 0.036) and in subjects with a plaque index > 40% (p < 0.001). Conclusions Root cap-retained overdentures with precision attachments are a viable treatment option in partially dentate subjects, even over long-term periods. However, high complication rates should be expected. Clinical relevance Establishing good oral hygiene is a decisive factor in preventing complications in RODs. Furthermore, CHX-containing products may not be recommended for routine domestic use.
