Materials and Methods: This randomized clinical trial included 14 patients who were seeking implant rehabilitation of partially edentulous atrophic ridge the in the esthetic zone. The patients were randomly and equally divided into two groups; immediate implants were placed simultaneously with each autogenous bone ring from chin group I (control group) and, with allogenic bone ring group II (study group). The evaluation was done immediately (T0), postoperatively at 1 month (T1), at 3 months (T3), and after 6 months (T6) to assess implant stability, soft tissue healing, relative buccal bone volume, and bone gain and bone loss around the dental implant. Results: The fourteen patients were randomly divided into two groups; 3 females and 4 males in group I and 2 females and 5 males in group II. Their ages ranged between18 to 45 years old with the mean age of both groups 31 years, standard deviation was 31.0+- 10.65 for group I and 31.0+-11.69 for group II. No statistically significant differences were found between both groups in implant stability, soft tissue healing, bone density, relative buccal bone volume, and buccal bone gain but the bone loss was higher in group I than group II with a statistically significant difference between them (1.61mm 2 versus 1.21 mm 2 ). Conclusions : The bone ring approach either allogenic or autogenous reduces treatment time for restoring function and aesthetics even in the severely atrophied alveolar bone.","PeriodicalId":308616,"journal":{"name":"Mansoura Journal of Dentistry","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129500083","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Materials and Methods: Fifty molar teeth were randomly assigned to one of five groups (n=10/group): Enamel (EN), Cementum (CE), Cention forte (CF), Tetric-N flow (TF), and Resin modified glass ionomer (RM) groups. Specimens were prepared for a standard MOD cavity with margins located 2 mm below the CEJ for CF, RM, TF, and CE groups, while the EN group had margins located 1 mm above the CEJ. DME was used to elevate the margins to 1 mm above the CEJ. For the CE group, the ceramic onlay was placed without DME. Standardized IPS e.max ZirCAD ceramic onlays were fabricated with CAD/CAM and bonded on all specimens with G-cem Capsule. All teeth were subjected to 10,000 cycles of thermocycling (5°C/55°C). The fracture resistance of each group was measured using a universal testing machine. Data was statistically analyzed using a one-way ANOVA test. Results: Fracture strength values were subjected to one-way ANOVA revealed statistically non-significant differences among experimental groups (p=0.08).

Materials and Methods: Six healthy completely edentulous patients were selected for this study. Each patient received a conventional complete denture then four implants were installed in the canine and premolar areas bilaterally. The implants were delayed loaded by mandibular overdenture using locator attachments, patients were classified into Group I: anterior two implants loaded by the overdenture; Group II: posterior two implants loaded by the overdenture; and Group III: four implants loaded with the overdenture, The bite force and the chewing efficiency were evaluated immediately 3 and 6 months after insertion. The exchange of loading between patients was done after each evaluation session. Results: There was a statistically significant difference in bite force and chewing efficiency between conventional complete dentures and implant-assisted overdentures regardless of the number and distribution of the implants after different observation times. The four implant-assisted overdentures showed a statistically significant difference in bite force and chewing efficiency compared with the other groups after all periods of overdenture insertion. Conclusions: Regardless of the implant number and location, implant-retained mandibular overdenture significantly increased the bite force and masticatory efficiency compared with the conventional complete denture. The four implants assisted mandibular overdenture significantly increased the bite force and masticatory efficiency compared with only two implants in the canine or premolar areas.","PeriodicalId":308616,"journal":{"name":"Mansoura Journal of Dentistry","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132940016","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Materials and Methods: This clinical cross-over study included 10 partially edentulous patients with the only remaining mandibular six anterior teeth. Every patient received two mandibular implants at the 1 st premolar region. Two mandibular implants' retained partial overdentures were constructed with two different support concepts, two different designs, opposing a maxillary single denture. One of the dentures was done with a design based mainly on soft tissue support but the other denture was done with a dual tooth-tissue support design. The effects of each RPD design were studied after 1, and 5 years. The following clinical parameters were evaluated: the plaque index (PI), the bleeding index (BI), and the probing depth (PD). The peri-implant bone level changes, and alveolar bone level changes of the canine and residual ridge bone level were assessed on digital radiographs using the Corel-Draw program. The SPSS program was used for statistical analysis. Results: After 1 and 5 years of follow-up for each supporting concept of RPD, no implant failures were noted. No significant differences in soft tissue clinical parameters BI, PI, and PIP were found between the 2 designs with regard to the canine and implant, or peri-implant bone resorption. On the other hand, there was a significant difference after 1 year regarding alveolar bone loss of the canine (P=.002) and residual ridge bone loss (P=.0001) and after 5 years for the canine alveolar bone where (P= .015). Regarding residual ridge bone loss, there was a distal descending pattern of bone resorption in the dual support design. The bone loss was increased with the dual support design (P=.0001). Conclusions: within the limits of this study, single soft tissue support for mesial implant retained removable partial overdenture was recommended versus dual tooth support. Single soft tissue support preserves the remaining structures.","PeriodicalId":308616,"journal":{"name":"Mansoura Journal of Dentistry","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133464551","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
