ATTACHMENT VERSUS CLASP RETAINED REMOVABLE PARTIAL DENTURES –A RANDOMIZED CONTROLLED CLINICAL TRIAL
(EDJ, 2019-04) Elawady, Dina Mohamed Ahmed; Ibrahim, Wafaa Ibrahim
Purpose: to compare two retainer designs for free end removable partial dentures (RPDs) by measuring the patient satisfaction, abutment tooth survival, bone height loss and pocket depth. Materials and Methods: Group 1: Fourteen patients receiving attachment-retained RPDs while group 2: Fourteen patients receiving clasp-retained RPDs. The assessment included patient satisfaction, survival of the terminal abutments, bone height loss and pocket depth. All patients were evaluated clinically and radiographically at the time of RPD insertion, twelve months and 24 months thereafter. Mann Whitney U test for independent samples was used for comparison of % change of patient satisfaction. Wilcoxon signed rank test for paired (matched) samples was used within group comparison of patient satisfaction before and after treatment. Survival analysis was done using Kaplan Meier statistics. For bone height, independent t-test was used and student’s t- test was used for pocket depth comparison. Results: There was a significant difference before and after treatment scores in Oral Health Impact Profile-14(OHIP-14), Orofacial Esthetic Scale (OES) and Chewing Function Questionnaire (CFQ) questionnaires in the clasp retained RPD group with P value = (0.001, 0.001 and 0.003) re- spectively. Regarding the attachment retained RPD group, there was a significant difference before and after treatment scores with P value = 0.001 for the three questionnaires. Within group compari- son it was found that there was a significant difference in OHIP-14 (P= 0.002) and OES (P<0.001) while there was no significant difference in CFQ between both groups (P=0.191). There was no statistically significant difference between both groups in terminal abutment survival (P=0.149) and percent change of the mean probing pocket depth from baseline to 24 months (P=0.05). However, regarding the effect of time on bone height change percentage for each group, a significant differ- ence was found between groups at baseline-twenty-four month’s interval (P-value < 0.05). Conclusion: Within the limitations of the present study, all patients have shown improvement in OHRQoL, esthetics and chewing function after treatment with RPDs with better results in the attachment retained RPD. However, regarding the terminal abutment survival, mean probing pocket depth and bone height change, clinically significant better results were revealed in clasp-retained RPD compared to attachment-retained RPDs
Botulinum toxin and occlusal splints for the management of sleep bruxism in individuals with implant overdentures: a randomized controlled trial
(Elsevier, 07/10/2021) Ali, Samer Mostafa; Alqutaibi, Ahmed Yaseen; Abo alrejal, Afaf; Elawady, Dina Mohamed Ahmed
Background The available treatment options fail to provide definitive or curative management for bruxer patients rehabilitated with implant overdentures (OD). The data regarding Botulinum toxin (BTX) injection as a management strategy for bruxism remains unclear. This randomized, single-blinded, control-group, pretest-posttest prospective trial evaluated the occlusal guard and Botox injections (BTX) effectiveness in managing sleep bruxism (SB) in subjects whose one of the edentulous arches had been restored with the implant-supported OD. Methods Forty-two patients diagnosed with definite bruxism were selected, all of which had implant-retained ODs opposing natural dentition. The participants were allocated randomly to three equal groups. Participants in group I (control group) were instructed to remove the OD at night; group II was managed with conventional occlusal stents. Those in group III were given BTX injections. New ODs were constructed for all groups, and all ball attachments were replaced with a new nylon cap. A baseline assessment (one month of OD insertion) of patient satisfaction and sleep quality was conducted, and then again at 3, 6, 9, and 12 months of treatment. Subjective sleep quality was evaluated using Pittsburgh Sleep Quality Index (PSQI). Patients’ satisfaction was evaluated using Temporomandibular disorders/numeric scales (TMD/NS). Prosthodontic (mechanical) complications were recorded during the follow-up period Results Group III showed a statistically significant improvement in patient satisfaction and sleep quality compared to the other two groups at 3, 6, 9, and 12 months follow-up period (P =0 .001, 0.0001, 0.0013, and 0.0001 respectively). Regarding prosthodontic (mechanical) complications, the highest number of events was revealed in the control group. Conclusions BTX and occlusal appliances effectively improve patient satisfaction and sleep quality of Bruxer patients rehabilitated with single arch implant overdentures.
IMMEDIATE VERSUS DELAYED IMPLANT PLACEMENT IN DIABETIC PATIENTS REHABILITATED WITH MANDIBULAR OVERDENTURES – A SPLIT MOUTH STUDY
(EDJ, 2018-10) Elawady, Dina Mohamed Ahmed; Osman, Reham B.
Purpose: This comparative controlled trial (CCT) evaluates the survival rate of implants placed into fresh extraction sockets and compare it with implants placed in healed sites in type 2 diabetic, completely edentulous subjects rehabilitated with mandibular implant overdentures (MIODs) fol- lowing a delayed loading protocol and opposed with conventional complete dentures. Materials and Methods: Fourteen implants were placed in seven well-controlled diabetic subjects as determined by Glycosylated hemoglobin (HbA1c) values before implant placement (baseline) and throughout the follow-up period. Each patient received two implants; one implant in healed canine site and the other was immediately inserted following the extraction of an existing periodontally hopeless canine. The implants were uncovered approximately 3 months after place- ment and restored with bar-retained overdenture. The patients were scheduled for regular follow-up appointments and for data collection. Kaplan-Meier analysis was used to calculate implant survival from time of prosthesis placement through 24-month follow-up period. Results: No implant failed in the delayed placement group within the 2 years study period, whereas in the immediate group two implants failed in two patients following the prosthetic loading at one-year follow-up period resulting in 71.2% implant survival rate. HbA1c levels ranging from 7.4 to 8.0 percent were identified in two patients with implant failures. There was no statistically significant difference in survival rate between immediate and delayed implants in type 2 Diabetic subjects rehabilitated with MIOD s (P=0.141). Conclusions: Within the limitations of this study, insufficient evidence exists to recommend immediate implant placement in type 2 diabetic subjects rehabilitated with MIODs.
Palatal vault configuration and its influence on intraoral scan time and accuracy in completely edentulous arches: a prospective clinical study
(The Korean Academy of prosthodontics, 2024-08) Elawady, Dina Mohamed Ahmed; Ibrahim, Wafaa Ibrahim; Ghanem, Radwa Gamal; Osman, Reham Bassuni
PURPOSE. The aim of this prospective clinical study was to compare the influence of palatal vault forms on accuracy and speed of intraoral (IO) scans in completely edentulous cases. MATERIALS AND METHODS. Based on the palatal vault form, participants were divided into three equal groups (n = 10 each); Class I: moderate; Class II: deep; Class III: flat palatal vault. A reference model was created for each patient using polyvinylsiloxane impression material. The poured models were digitized using an extraoral scanner. The resultant data were imported as a solid CAD file into 3D analysis software (GOM Inspect 2018; Gom GmbH, Braunschweig, Germany) and aligned using the software’s coordinate system to determine its X, Y, and Z axes. Five digital impressions (DIs) of maxilla were captured for each patient using an intraoral scanner (TRIOS; 3Shape A/S, Copenhagen, Denmark) and the resultant Standard Tessellation Language (STL) scan files served as test models. Trueness was evaluated by calculating arithmetic mean deviation (AMD) of the vault area between reference and test files while precision was evaluated by calculating AMD between captured scans to measure repeatability of scan acquisition. The scan time taken for each participant was also recorded. RESULTS. There was no significant difference in trueness and precision among the groups (P =.806 and.950, respectively). Average scan time for Class I and III palatal vaults was 1 min 13 seconds and 1 min 37 seconds, respectively, while class II deep palatal vaults showed the highest scan time of 5 mins. CONCLUSION. Palatal vault form in edentulous cases has an influence on scan time. However, it does not have a substantial impact on the accuracy of the acquired scans.
