The aim of this retrospective study was to evaluate ridge expansion after osseodensification.Materials and methods: Patients treated with implant placement through osseodensification were evaluated. The alveolar ridge width was measured at the level of the crest and 10 mm apical to the crest before and after osseodensification. Insertion torque and implant stability quotient (ISQ) values were recorded at implant placements. Expansion values were grouped into the following 3 groups according to the initial alveolar ridge width: group 1: 3 to 4 mm (n = 9), group 2: 5 to 6 mm (n = 12), and group 3: 7 to 8 mm (n = 7).Results: Twenty-one patients who received 28 implants were included. Twenty-six implants were integrated, resulting in a survival rate of 92.8%. There was a significant difference in the mean expansion value at the coronal aspect of the ridge between group 1, group 2, and group 3 (2.83 ± 0.66 mm, 1.5 ± 0.97 mm, 1.14 ± 0.89 mm, P < 0.05). The mean torque and ISQ values were 61.2 ± 13.9 Ncm and 77 ± 3.74.Conclusion: Osseodensification can alter ridge dimensions and allow for ridge expansion. Greater expansion can be expected at the crest in narrow ridges with adequate trabecular bone volume.","PeriodicalId":13309,"journal":{"name":"Implant Dentistry","volume":"28 4","pages":"349-355"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1097/ID.0000000000000898","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"37395291","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 aim of this study is to evaluate submandibular fossa anatomy in the posterior mandible using cone-beam computed tomography (CBCT) scans.\u0000\u0000\u0000STUDY DESIGN\u0000One hundred thirty-two preimplant CBCT examinations were used. Several morphometric measurements were performed in the submandibular fossa. Moreover, each patient was classified according to the Kennedy classification. Statistical analysis was used to test the relationship among measurements, sex, side, and each tooth.\u0000\u0000\u0000RESULTS\u0000A total of 2412 measurements were performed from all patients. The deepest concavity at the submandibular fossa in all Kennedy Class groups was in the 1st and 2nd molars. The concavity depth was statistically higher in class I group for 1st and 2nd molars than the other Kennedy Class groups. Class IV group showed less depth than the other groups.

Clinical and radiographic measurements were recorded in 10 years and analyzed statistically using t test.Results: A total of 26 patients (20 females and 6 males) with 30 implants were available for the 10-year follow-up.

Eight weeks after the ovariectomy, upper right molar was extracted and an implant was placed at 4 weeks post-extraction. The RAL group was administered with 1 mg/kg/d of raloxifene via gavage while the OVX group and the control group received saline only. Three rats in each group were sacrificed at 1, 4, 7, 14, and 28 days and histologic sections were evaluated by hematoxylin and eosin staining and micro-computerized tomography was taken.Results: The RAL group showed faster bone formation around the implant than the OVX group. At 4 weeks after implantation, newly formed bone close to implant threads was mature with considerable quantity of bone marrow in the RAL group.Conclusion: Raloxifene showed increased bone formation around implant.
