Journal articles on the topic 'Partial edentia'

Objective: To determine the changes that occur in periodontal tissues, prosthetic bed and oral mucosa before and after orthopedic treatment when using metal-free ceramic prostheses. Methods: During the study, general clinical, laboratory, biochemical, functional, instrumental and statistical methods were used. The object of the study was 185 patients with partial edentia aged 25-60 years were selected, 95 of whom were men and 90 were women, and the control group consisted of 20 healthy people. Results: The wear of non-removable prostheses during wearing is manifested in the following pathological changes in the condition of the prostheses and the tissues of the prosthetic bed. Stamped and stamped welded prostheses with and without ZDP TT have a number of technological shortcomings, which are manifested during wearing. Conclusions: Dentures lead to a change in the acid-base balance of oral fluid, complete cast dentures without a protective and decorative coating have the least effect on it ((pH 7.2±0.03, from 12 months after denture insertion to the end of the study), metal-ceramic dentures have a small effect (pH 7.39±0.02 from 12 months after denture insertion to the end of the study).

Aim: To Improve the treatment of patients with partial edentia and chronic generalized periodontitis by including dental implantation to the complex of therapeutic measures. Materials and methods: There have been presented the results of 240 patients with varying severity degrees of generalized periodontitis who underwent surgery on periodontal tissues with dental implantation. The research was conducted at the OCH of Ivano-Frankivsk 2007–2017.To improve the efficiency for dental implants and periodontal surgical intervention is necessary to determine the quality of bone remodeling, identifying markers of bone tissue metabolism. Results: It was established that in 40,81 % patients the results of research showed markers of bone remodeling indicating a high rate of bone formation (25,12±2,23 ng / ml) and a slight increase in rate of resorption marker, which results in low rates of bone resorption (8,54±1,23 nmol/L). These patients were not prescribed with osteotropic drugs. 50,83 % of patients with osteopenia were noticed to manifest the formation of bone possible raise of bone resorption (10.82±1.34n/mole), which was the indication for antiresorptive medication prescription. In 8,36 % of patients with osteoporosis was observed inhibition of bone formation processes (18,05±2,08 ng / ml) and increased resorption indices (15,34±1,87 nmol/L). Medications that stimulate osteogenesis and prevent bone resorption were prescribed. Conclusions: When planning dental implants and periodontal surgical intervention it is necessary to identify markers of bone remodeling to assess the structural and functional state of bone tissue and prescribe osteotrophic drugs that promote positive postoperative period.

Background. Implant dentistry is becoming one of the most popular rehabilitation strategies for patients with partial or complete secondary edentia, which dictates the need to develop innovative osteoplastic materials and surgical bone reconstructive techniques. Objective. Conduct an objective assessment of the effectiveness of various types of sinus lift using instrumental and laboratory criteria Material and methods. The results of surgical treatment of 50 patients (19 men (38%) and 31 women (62%)) aged 29—72 years with dentition defects and atrophy of the alveolar process of the upper jaw were analyzed. 30 patients (group 1) underwent closed sinus lift surgery using the author’s technique with simultaneous implantation, 20 (group 2) underwent open sinus lift surgery. Control examinations were carried out in both groups before surgery, 3, 6 and 12 months after dental implantation. We assessed: the incidence of complications, primary and secondary stability, the percentage of dental implant rejections, and the electrokinetic mobility of buccal epithelial cells. Results. In patients of group 1, no intraoperative complications were registered; the sutures were removed on the 7th day; no delayed complications were identified. In group 2, bleeding from the alveolar arterioles was observed in 4 patients during the operation, and perforation of the Schneiderian membrane was observed in 2 patients. In the early postoperative period, non-critical vascular phenomena (edema and hematomas) were observed. Sutures were removed on days 10—14. The primary stability indicators of the torque test were 31.1 n/m and 9.4 n/m, periosteometry –2.15 and –1.42, in groups 1 and 2, respectively. Indicators of secondary stability at 12 months of follow-up were 51.9n/m and 46.3n/m, –8.76 and –6.95, respectively. Conclusion. The developed method of closed sinus lift, performed in conditions of severe bone tissue atrophy, reduces the invasiveness of bone augmentation, helps reduce the number of intra- and postoperative complications and accelerates the rehabilitation process of patients with secondary adentia.

The leading etiologic factor in the development of peri-implantitis is microorganisms, which, due to the development of the infectious process, cause resorption of bone tissue directly adjacent to the implant, followed by its disintegration and removal. The aim of this study was to develop reliable and informative algorithms for diagnosing the development of peri-implantitis, which will maximally include safe and affordable methods. Objects and methods. Patients aged 20 to 48 years were examined, with a partial secondary edentia. All patients were randomly divided into two groups, comparable by demographic, nosological indicators. The first group consisted of 248 patients with osseointegrated implants, the second group consisted of 26 individuals which based on examination of the clinical picture and the results of X-ray, verified the diagnosis of peri-implantitis. A phased examination was conducted. To determine antibodies to Helicobacter pylori in the saliva, the diagnostic immunochromatographic membrane test method of the test cassette was used in patients of both groups in accordance with the method proposed by the authors. The second stage was the cytological examination of the contents from the bone cavity after removal of the implant and the third stage was the release of Helicobacter pylori DNA in the saliva. Results and discussion. A detailed result of analysis of patient’s examination made it possible to establish the following. Parameters of antibodies to HP in the saliva during the immunochromatographic test revealed the presence of antibodies to HP in 37 (15%) patients of the first group with osseointegrated implants and in 26 (100%) patients of the second group with peri-implantitis. The microbiological composition in the cytological study with peri-implantitis is presented: mixed and coccal flora in 4 patients (10%), fungi in 3 patients (11%), Helicobacter pylori in 24 patients (93%), lymphoid elements, erythrocytes and leukocytes in 26 patients (100%). A comparative evaluation of the results of the polymerase chain reaction in patients of the two groups showed that a positive result (the presence of Helicobacter pylori DNA) in the first group was detected in 20 patients — 23% of the observations. In the second group, a positive PCR test was determined in 26 patients, which was 100% of the observations. Each of the laboratory methods for detecting HP has its advantages and disadvantages, as well as its sensitivity and specificity. Numerous comparative studies have shown that the results obtained using different methods are not always identical. In this case, the result should be considered positive or negative when the indicators of all applied methods of research coincide. Conclusion. The obtained results are the basis for the conclusion about the presence of a definite relationship of the pathological inflammatory process in the bone tissue of the jaw directly adjacent to the dental implant and the character of Helicobacter pylori carriage in the observed patients.

Objective: the objective of this study was to evaluate the influence of partial or total edentulism on the quality of life of elderly patients. Material and Methods: the sample consisted of 120 individuals, divided into edentulous patients with bi-maxillary complete dentures (CD) (n = 60) or partially edentulous individuals with maxillary CD and mandibular removable partial denture (RPD) (n = 60). Patients' quality of life was assessed using the OHIP-EDENT-19 questionnaire and the data were analyzed using the SPSS software. Results: patients using RPD presented higher quality of life compared to users of double CD, according to the values presented in OHIP-EDENT. Statistically significant differences were found when comparing the groups between complaints related to chewing (difficulty chewing, discomfort when eating, avoiding eating, interruption of meals), psychological discomfort and incapacity (unable to eat), social incapacity (unsatisfactory life), and painful mouth and discomfort (unsuitable prostheses, sore mouth). Conclusion: the type of prosthesis used may influence self-reported quality of life.

Introduction. Currently, the direction of minimally invasive surgical interventions in surgical dentistry is relevant to reduce the time of postoperative rehabilitation. Detachment of the mucoperiosteal flap during dental implantation leads, depending on the extent of the defect, to a hematoma, which increases the risk of complications (suture dehiscence, wound infection). Because of this, treatment tactics have been developed that allow dental implantation to be performed using surgical navigation templates using a flapless technique. However, despite the obvious effectiveness and efficiency of the method, there are few experimental studies to substantiate the flapless technique of dental implantation.Purpose: clinical substantiation of the effectiveness of the use of flapless navigation techniques for dental implantation Materials and methods: the clinical study included 40 patients with secondary partial edentia. The patients were divided into two groups: the main and control groups. A life history was collected, as well as a history of the development of the present disease. The patients underwent dental implantation surgery in the area of the lateral groups of teeth. In the main group, dental implantation was carried out using a navigation template with a complete protocol and the use of a “flapless” technique; in the control group, dental implantation was carried out with a full-thickness incision and detachment of the mucoperiosteal flap. The evaluation criteria were clinical parameters of healing in the early postoperative period, the height of the soft tissues around the dental implant in the late postoperative period (CBCT, probing), as well as the presence of complications (mucositis, peri-implantitis). The data was entered into a table for further statistical analysis.Results. In the control group, the average height of the formed gingival cuff was 1,55±0,43 mm, 95% CI (1,34–1,75), with primary healing the average height was 1,64±0,44 mm, 95% CI (1,31–1,98), with secondary healing the average height is 1,46±0,43 mm, 95% CI (1,17–1,75). In the main group, the average height of the formed gingival cuff was 2,42±0,45 mm, 95% CI (2,21–2,62), with primary healing the average height was 2,40±0,45 mm, 95% CI (2,17–2,63), with secondary healing mean height 2,50±0,53 mm, 95% CI (1,19–3,81). In the control group, the average loss of marginal bone tissue was 1,27±0,47 mm, 95% CI (1,05–1,49), with primary healing the average loss was 0,96±0,29 mm, 95% CI (0,73–1,18), with secondary healing the average loss is 1,53±0,44 mm, 95% CI (1,23–1,82). In the main group, the average loss of marginal bone tissue was 0,50±0,31 mm, 95% CI (0,35–0,65), with primary healing the average loss was 0,48±0,33 mm, 95% CI (0,31–0,65), with secondary healing the average loss is 0,63±0,12 mm, 95% CI (0,35–0,92). Comparison of the main and control groups in terms of the height of the formed gingival cuff showed a statistically significant difference (p<0,001). This indicator differs significantly between groups with primary (p=0,0004) and secondary wound tension (p=0,004). In the early period, in the control group of 20 patients, 8 (40%) had mucositis, 2 (10%) had peri-implantitis, in the main group 3 (15%) had mucositis. In the late period, in the control group, 7 (35%) had mucositis, 1 (5%) had peri-implantitis, in the main group, 2 (10%) had mucositis. A comparison of the main and control groups in terms of the presence of pain, as well as the presence of complications in the early and late periods, showed a significant difference. In the control group, 60% of patients felt pain, and in the main group, 15% (p=0,009). The presence of complications in the early period was observed in 50% in the control group and in 15% in the main group (p=0,042). In the late period, the proportion of complications decreased and amounted to 40% in the control group and 10% in the main group (p = 0,03). The groups differ in the proportion of primary and secondary healing, so in the main group 85% of patients had primary healing, and in the control group patients with secondary healing of 55% predominated (p = 0.02). Comparison of the study and control groups in terms of loss of marginal bone tissue showed a statistically significant difference (p<0,001).Conclusion. The use of a flapless navigation technique can reduce the likelihood of complications in the early and late postoperative periods, while predictably controlling the height of the gingival cuff.

&nbsp; &nbsp; <em>Today, a pressing problem for the population is the loss of a significant number of teeth, which most often occurs as a result of dental diseases such as caries and its complications, periodontitis, and injuries to the maxillofacial region. The increasing destruction of the dental system leads to tooth loss. In this case, the main function of the masticatory apparatus is impaired, as well as the speech function and aesthetic standards. Defects in the dental arches can lead to occlusion disorders with further development of temporomandibular joint disease. Many patients, especially young people, refuse removable dentures due to unsatisfactory fixation and stabilization of the structure, painful sensations when chewing, as well as due to the impact on the psychoemotional state [5]. For several decades, orthopedic structures with support on implants, which are implanted into the alveolar bone, have been popular among patients with partial or complete absence of teeth. This can be explained by the fact that this design creates the most accurate restoration of functions than other types of prosthetics[6].</em> &nbsp;

The main postulate of periodontal treatment is the elimination of factors injuring periodontal disease, creating conditions for the normalization of its properties. Structures with additional supports on the intraosseous implants are optimal for orthopaedic treatment. The possibilities and conditions for surgical intervention on periodontal tissues and implantation in patients with varying severity of chronic GP were generally poorly understood.The aim of the study – to improve the treatment of patients with partial edentia and chronic generalized periodontitis by including dental implantation to the complex of therapeutic measures.Materials and Methods. There are presented the results of 360 patients with varying severity degrees of generalized periodontitis who underwent surgery on periodontal tissues with dental implantation.Results and Discussion. Our research showed that implantation in patients with mild generalized periodontitis can achieve consistently good results regardless the method of treatment. Simultaneous surgery on periodontal tissues and the dental implantation shortens treatment duration in 1.5–2 times without compromising its quality. It is shown that in patients with moderate and severe degrees of generalized periodontitis it is appropriate to perform periodontal surgery separately followed by dental implantation to prevent postoperative complications and implant loss. When planning for dental implants and periodontal surgical intervention it is necessary to determine the quality of bone remodeling to assess the structural and functional state of bone tissue and differentiated destination osteotropic drugs that promote positive postoperative period.Conclusions. Therefore, in order to increase the effectiveness of dental implantation and surgical periodontal intervention, bone remodelling markers should be determined to assess the structural and functional status of bone tissue and for the differentiated use of osteotropic drugs, which will contribute to the positive development of the postoperative period. Simultaneous surgical intervention on periodontal tissues and dental implantation in 1.5–2 times reduces the duration of treatment without reducing its quality. In patients with moderate to severe degrees, it is expedient to carry out surgical interventions with subsequent dental implantation in order to prevent postoperative complications and loss of implants.

Introduction: Implant supported prosthetic rehabilitation could re-establish the comfort and bring a confident smile to patients, allowing them to eat properly and to lead a social life free of traumas and complexes. Aim: To verify which type of implant-supported rehabilitation- overdenture or fixed denture effectively restores the comfort of the lower arch of partial edentulous patients. Materials and Methods: A cross-sectional clinical study was performed in patients with completely edentulous lower arch treated with either overdenture (2 implants) or fixed denture (5-6 implants), obtained from a sample from Southern Brazil. The study sample was composed of 37 volunteers who met the inclusion and exclusion criteria. Half of them were rehabilitated with overdenture (O- ring and bar) and the other half with fixed denture (Branemark protocol). A clinical evaluation was performed to obtain the Index of Plaque (PI) and bleeding on probing indexes (BI). Three questionnaires were applied to quantify the patient’s level of satisfaction with their prosthetic treatment (OHIP-EDENT and masticatory ability questionnaires) up to one year after installation of the prosthesis. Results were analysed by the Mann-Whitney test (α=0.05). Results: All treatments were considered satisfactory regarding masticatory ability. However, fixed dentures had a statistically higher level of satisfaction compared to overdenture. There were significant differences in the mean PI and BI index between the groups. Conclusion: Both rehabilitation treatments increased the satisfaction and improved the oral health and masticatory ability of edentulous patients. However, although patients rehabilitated with fixed dentures presented higher level of satisfaction, they also showed higher plaque and bleeding on probing indexes.

Objective: The aim of this study was to evaluate factors affecting oral health related quality of life (OHRQoL) of patients using removable dental prosthesis.&#x0D; Methods: The present study employed a cross sectional analytical design. A total of 200 patients participated and interviewed using a cross sectional analytical design. In the first section of the questionnaire patients were asked about demographic data whereas the second part of the questionnaire assessed medical history, oral habits, smoking status, oral hygiene habits and frequency of dental visit. The questionnaire also collected information regarding patient’s removable prosthesis. Questionnaire of OHIP-DENT (Oral Health Impact Profile) was also employed to measure oral health quality of life (OHRQoL) on the domains of functional limitation (FL), physical pain (P1), psychological discomfort (P2), physical disability (D1), psychological disability (D2), social disability (D3) and handicap (H). Relationships between the demographic, socio-economic and education variables and others OHIP-EDENT scores were explored by comparing mean scores by applying ANOVA&#x0D; Results: The study participants comprised of 107 males (53.5%) and 93 females (46.5%). Regarding oral care, participants reporting to visit their dentist within one year were 40.0%. The highest score was recorded for the functional limitation (FL) domain (15.62±6.6), followed by social disability (D3) (15.23±5.06) and physical pain (P1) (14.28±4.8). The respective scores for physical (D1) and psychological disability (D2) and handicap (H) were 10.47±4.84, 11.32±5.38 and 12.45±4.50 respectively.&#x0D; Conclusions: Removable partial denture patients showed minimum problems with mastication, social compromise and functional discomfort. The oral health quality of life of removable denture patients is significantly influenced by patient education level, socio-economic status, medical conditions, smoking and tobacco use habits.&#x0D; doi: https://doi.org/10.12669/pjms.36.2.1257&#x0D; How to cite this:Al-Deeb M, Abduljabbar T, Vohra F, Zafar MS, Hussain M.
