This study aimed to correlate and compare pixel values of healed maxillary sinus grafts and adjacent native bone (NB).Material and methods: This study was conducted on CBCT scan patients referred for maxillary sinus floor augmentation with biphasic calcium phosphate (n = 31). Graft height and width measurements were performed. In addition, mean pixel values were calculated in 3 different regions: NB, sinus graft close to NB (CNB), and sinus graft far from NB (FNB). Micro-CT and histological analyses of bone specimens of a representative case were also performed.Results: Significant correlations were found between CNB and graft height (r = 0.41; P < 0.021); and FNB and graft width (r = 0.519, P < 0.003). In addition, pixel values from both graft groups (CNB and FNB) differed significantly (P < 0.001). Finally, histological sections revealed smaller areas with newly formed bone in the FNB area.Conclusions: Within the limitations of this study, the present findings suggest that pixel values of sinus grafted areas are directly correlated with the extension of the grafted area.","PeriodicalId":13309,"journal":{"name":"Implant Dentistry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1097/ID.0000000000000823","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"36575306","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}

The gaps around implants were grafted with deproteinized bovine bone mineral. According to the size of the alveoli, the implants were connected with titanium healing abutments (traditional group) or customized healing abutments (CA group). Radiographic and intraoral examinations were performed before surgery, postoperatively, and at the 6-month recall.Results: Buccal (P = 0.717) and lingual (P = 0.087) vertical bone loss was comparable between groups. More significant incomplete defect fill was found at the distal aspect of the CA group (P = 0.000). The buccal bone thickness alterations were similar between the 2 groups (P = 0.902 at the implant platform). The mid-facial soft-tissue level was well maintained in both groups.Conclusions: Within the limitations of this study, for immediate implants placed into posterior sockets, customized healing abutments can facilitate closure of large sockets. Despite more pronounced incomplete defect fill, healing abutments consisting of polyether ether ketone and resin did not render an increased risk for periimplant bone loss or soft-tissue recession during the early healing period.","PeriodicalId":13309,"journal":{"name":"Implant Dentistry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1097/ID.0000000000000809","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40554768","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}

The same probe was also used to detach the Schneiderian membrane from the bony floor of 21 human subjects undergoing tSFE.Results: The force needed to cause membrane perforation in the cadaver sample was on average 3.46 ± 1.04 N. The maximum force applied in vivo to a sinus membrane without perforation was 2.01 ± 0.67 N on average. Regression analysis showed that smoking (P < 0.001), as well as 3.0 mm osteotomy (P < 0.001), was significantly correlated to increased forces during membrane detachment.Conclusions: The maximum force needed to detach the membrane was found to be, on average, lower than the membrane breaking load in cadavers. Furthermore, because of smoking and a 3.0-mm osteotomy diameter demonstrating a high association with increased forces during membrane detachment, they may be considered as risk factors of membrane perforation.","PeriodicalId":13309,"journal":{"name":"Implant Dentistry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1097/ID.0000000000000817","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"36437878","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}

BMCs were noted and classified according to Naitoh. Demographic data were also collected and analyzed.Results: Twenty-eight patients were noted to have bifid mandibular canal, with an average age of 39 years (± 19.5), with no strong sex predilection. Patients (1.31%) were noted to have bifid canals. A greater percentage of patients were shown to have bilateral bifid canals (42.9%) versus either unilateral side (25% left, 32.1% right), but is statistically insignificant. Prevalence was greatest in types 1 and 3 (35.9% and 51.3%, respectively, P = 0.000011).

X-ray, cone-beam computerized tomography imaging, implant stability quotient (ISQ) values, histological observation, quantitative analysis of bone histomorphometry, and hematoxylin-eosin (HE) and Masson staining were evaluated.Results: In this study, at 4 weeks after the surgery, the mean ISQ value in the HBO group was higher than that in the blank group, and the difference had statistical significance (P < 0.05). At week 4 and 8, the mean values of bone ingrowth fraction (BIC%) and the percentage of bone area (BA%) in the HBO group were both higher than those of the blank group. Decalcified paraffin sections were stained with HE and Masson staining showed that the bone tissue around the implant in the HBO group has more osteoblasts than control group, and many irregular marrow cavities and Haversian bone plates were observed in the new bone tissue.Conclusion: This study showed that after implantation, early osteogenesis was better in the HBO group than in the blank group.
