Shahraki, Mohammad Reza Hakimaneh, L. Mahesh","doi":"10.5005/JP-JOURNALS-10012-1076","DOIUrl":"https://doi.org/10.5005/JP-JOURNALS-10012-1076","url":null,"abstract":"Purpose: The aim of this study was to compare the clinical and radiographical outcomes of two loading protocols of mandibular overdentures supported by two unsplinted implants. Materials and methods: Twenty completely edentulous patients were included in the study. Patients were categorized in two groups each containing 10 patients. In group A, patients received at least two implants in symphysis areas inserted after a minimal flap reflection, and 2 months after implant placement, a mandibular complete denture was connected to the implants using ball attachments. In second group, prosthesis was loaded immediately after placing the implants in symphysis areas without any flap reflection. Patients were examined at 1, 12, 24 and 48 weeks after loading. At postoperative visits, occlusion was checked and the need for any prosthesis maintenance was recorded. Mobility of the implants, radiolucency around the implant and amount of crestal bone loss was checked and measured for both groups during the checkup sessions. Also any prosthetic problems were recorded. Results: After 12 months of loading, in both group no implant failure was reported and the survival rate was 100% in immediate and delay loading groups. Average of bone resorption in control group at the end of study was 0.84 ± 0.05 mm and in the test group was 0.84 ± 0.03 mm. In all patients after every 6 months the plastic O-rings were changed due to frictional wearing. In test group, in three patients the mandibular denture fractured, while, in control group it happened in two patients. In the test group, two patients experienced unbearable pain, while, in the control group seven patients experienced unbearable pain and they needed analgesics. None of the patients in test group experienced edema, swelling and discomfort after surgery due to flapless surgery, while in the control group four patients experienced edema and swelling after surgery. Conclusion: The results of this study suggest that immediate loading of two implants supporting mandibular overdenture has outcomes comparable with conventional loading protocols. This clinical approach offers good stability and comfort while keeping high implant success rate.","PeriodicalId":303737,"journal":{"name":"International Journal of Oral Implantology and Clinical Research","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128061983","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}

Currently, clinical excellence involves placing implants in diameter and size appropriate. In order to achieve this goal, it is often necessary to reconstruct the alveolar process of the patient. One of the techniques used for this purpose today is distraction osteogenesis, which has proven to be an effective and predictable technique. The objective of this article is to present a clinical case of partial reconstruction of the alveolar bone, using mini-implants to anchor the bone block that will be moved. This variation of the conventional technique minimizes the risks inherent in using conventional distractors.","PeriodicalId":303737,"journal":{"name":"International Journal of Oral Implantology and Clinical Research","volume":"246 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122871080","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}

A current area of hot debate is the significance of the implant abutment interface and its influence on crestal bone level in relation to the first thread. In recent years, the microgap which exists at the connection between the implant body and the restorative abutment has been implicated. Recently, it has been suggested that the presence and position of the microgap may not be the principal cause of bone resorption phenomenon, but instead that it is due to the relative diameters of the abutment and the implant platform. It appears desirable to incorporate features into implant design which reduce microleakage or limit its effects. A tapered implant abutment creates a microseal and the hermetic seal produced eliminates the microgap preventing the passage of bacteria. Hence platform switching may limit or confine the effect.","PeriodicalId":303737,"journal":{"name":"International Journal of Oral Implantology and Clinical Research","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129584717","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}

Preoperative prediction of the antral membrane thickness would be of practical importance and serves as an additional information for surgical planning. The purpose of this study was to analyze a possible correlation and comparison between gingival phenotype and the residual ridge height on the dentulous and the edentulous side to the thickness of the healthy sinus mucosa. Materials and methods: Twenty-five consecutive patients were included in the study; preoperative cone beam computed tomography (CBCT) scanning was performed to radiographically evaluate the gingival phenotype (GP), the height of the residual ridge (RRH) at the edentulous side and the dentulous side and thickness of the schneiderian membrane (SMT). The smallest RRH, highest SM and gingival thickness values were recorded. These values were classified as follows: RRH 3.5 mm; SM 1 mm; and GP 2 mm. Results: On the edentulous side, Strong correlations of GP with SM (r = 0.833, p < 0.001) and moderate between RRH with SM (r = 0.620, p = 0.001) and RRH with GP (r = 0.596, p = 0.001) were noted. On the dentulous side, strong correlations of GP with SM (r = 0.832, p < 0.001) and moderate between RRH with SM (r = 0.643, p = 0.001) and RRH with GP (r = 0.601, p = 0.001) were noted. Conclusion: Within the limitations of the study, the gingival phenotype (GP) presents to be a reliable measure to predict the thickness of the SM and suggested that the GP, SM, RRH may be important factors for sinus perforation.","PeriodicalId":303737,"journal":{"name":"International Journal of Oral Implantology and Clinical Research","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114659152","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}

All the implants were placed immediately after extraction. The minimum follow-up period was 6 months with PT readings taken at 4th, 5th and 6th months (stage I) and after restoration at 7th, 8th and 9th months.Results: Negative values are generally considered good. This means the implant is well osseointegrated and can be loaded. The PT values for the maxillary tooth were lower than those for the mandibular tooth. A stable mandibular implant presents PT value readings between �2 and +2. A stable maxillary implant presents PT value reading between �4 and �2.Conclusion: PT enables us to assess osseointegration noninvasively and objectively in any situation. PT helps us to optimize our decision whether or not an implant is ready for functional loading.","PeriodicalId":303737,"journal":{"name":"International Journal of Oral Implantology and Clinical Research","volume":"43 3-4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120909443","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}
