Variables associated with sinus membrane (SM), sinus dimensions, ostium, septa, sinus neighborhood, alveolar bone height and ridge width, posterior superior alveolar artery, and adjacent roots were evaluated.Results: No (58.2%) or flat (19.3%) thickening morphology was detected at most of the SMs. Membrane thickening and mucosal-like morphology was more prevalent for male patients (P = 0.005). The mean sinus width was relatively low (3.64 ± 3.33 mm) at the 5-mm level and showed an expected increase toward upper levels. Most of the sinus spaces were dimensionally average (39.5%) or wide (44.7%), and no effect of gender was observed in terms of sinus dimensions (P > 0.05).Conclusion: Multiple teeth loss plays a role in creating an imaginary sinus anatomy constituted of a relatively narrow space compared with single-tooth loss cases, from 3.6-mm mean coronal width to 11.3 mm in the apical portion.","PeriodicalId":13309,"journal":{"name":"Implant Dentistry","volume":"28 3","pages":"226-236"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1097/ID.0000000000000862","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"37274249","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At the same time, 44% of articles note that implant diameter can be considered a more effective design parameter than implant length to reduce stress concentrations and to avoid an overload of periimplant bone. Regardless of implant dimension, in all studies, the highest stress concentrations are found in the cortical section around the upper part of the implant.Conclusions: Unaffected of bone quality, implant diameter is found to play a key role to minimize periimplant stress concentrations. Concerning stress reduction implant length gains increasing relevance with decreasing bone density.

The alkaline phosphatase activity, calcification, and mineralization were gradually increased in the MG-63 cells treated with PRF. Furthermore, the mRNA levels of biomarker gene in the MG-63 cells treated with PRF were significantly higher than those of control.

This can increase quantity and density of periimplant bone. This review represents a summary and a critical appraisal of the studies regarding osseodensification in the literature.Materials and methods: Three databases were searched: PubMed (MEDLINE), Cochrane Library, and Latin American and Caribbean center on health sciences information (LILACS). Studies were screened by title/abstract according to predetermined eligibility criteria. Full texts of 7 eligible articles were read among which 2 were excluded and 5 articles were included and underwent qualitative synthesis.Discussion: Studies advocating osseodensification are sparse and mainly animal studies of low evidence level. High risk of bias and low correlation between used animal models and human bone were detected in most of the studies.Conclusion: Although osseodensification seems to be a very promising technique, the findings are inconclusive and should be cautiously interpreted. Well-designed animal and human studies of longer follow-up periods are required before implementing such technique in regular daily practice.","PeriodicalId":13309,"journal":{"name":"Implant Dentistry","volume":"28 3","pages":"306-312"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1097/ID.0000000000000884","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"36994225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
