Periodontal indices including plaque index (PI), bleeding on probing (BOP), and probing depth (PD) were clinically recorded around natural teeth and implants at baseline and after a period of 1 month and 3 months. \u0000Results After 3-month evaluation in the test group the differences of plaque and bleeding indices remained statistically significantly lower compared to baseline at both teeth and implants. Contrariwise, no statistically significant differences of PI and BOP were observed in the control group. The intergroup comparison at 3 months yielded statistically significantly lower values for all periodontal parameters around teeth when the probiotic was used. Conversely, no statistically significant differences in periodontal parameters were observed between test and control groups at 3 months around implants. \u0000Conclusions Probiotic intake was effective in reducing PI, BOP, and PD scores around natural teeth and dental implants affected by peri-mucositis, in particular around natural teeth at 3 months.","PeriodicalId":42724,"journal":{"name":"Journal of Osseointegration","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2021-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82001266","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}

Most of studies presented repair procedures via a lateral approach, which can induce additional complications. Therefore, in the present study the procedure was performed via crestal approach. \u0000Case report This study included three patients who showed a low residual alveolar bone height in the maxillary posterior edentulous region and in whom the placement of implants with sinus floor elevation was planned via a transalveolar approach. Perforation of the sinus membrane occurred during the procedure, and so collagen dressing material was inserted through the drilling hole to cover the perforated membrane. Xenogeneic bone was grafted under the elevated sinus membrane, and implants were placed simultaneously. The final prostheses were delivered at 6 to 8 months after the surgery. There were no complications in any of the patients. \u0000Results All implants showed successful stability, and no specific clinical or radiographic complication was observed during follow-ups lasting 2 to 3 years. \u0000Conclusion A crestal approach can be a reliable option when repairing a sinus membrane that is perforated during transalveolar sinus floor elevation.","PeriodicalId":42724,"journal":{"name":"Journal of Osseointegration","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2021-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81227045","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}

This report analyzes the efficacy of these barriers, when they are inserted in a surgical slot, vestibular to the defect, using the new Bone into Bone (BiB) technique. \u0000Methods A group of 20 patients were treated with the BiB technique, and 32 implants were placed. Bone samples were collected with trephine burs 8 months after surgery and submitted to histological and histomorphometric analysis. The linear horizontal and vertical changes between pre-operative and post-operative radiographs were measured on the CT Scan. \u0000Results A mean width gain of 2.36 ± 0. 0.69 mm and a mean height gain of 3.13 ± 0.90 mm was recorded. The biomaterial was almost completely resorbed, and it accounted for 7.39% ± 7.70 of the samples. \u0000Conclusion Comparing the current results with those of other investigations, the BiB technique is an efficient alternative to other regenerative approaches, as it provides several advantages, both in terms of reduced morbidity and ease of the procedure. More reports are needed to evaluate the stability of the regenerated bone and to directly compare this technique to other, more commonly used, regenerative procedures.","PeriodicalId":42724,"journal":{"name":"Journal of Osseointegration","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2021-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85365186","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}

Today, autogenous grafts are still the gold standard. The aim of this study was to evaluate the bone stability of horizontal bone grafts taken from the iliac crest. \u0000Materials and metods Twenty patients receiving horizontal bone grafts were included in this retrospective cohort study.

It was observed that the average bone thickness increased from 2.38 mm to 7.22 mm. \u0000Conclusions The result of the present study highlight that thicker block grafts, which were applied due to the expected resorption rate, result in a higher resorption rate after recovery.

The impact of implant thread design and diameter on the biomechanical performance of all-on-four concept is not yet fully understood. The purpose of this study was to investigate the biomechanical behavior of all-on-four concept with different combinations of thread designs and diameters through a three dimensional Finite Element Analysis. \u0000Materials and methods Six three-dimensional finite element models of edentulous mandible were developed. The models included the combinations of 3.5 and 4.3 mm diameter implants with active and passive thread designs. Vertical, oblique and horizontal loads were applied anterior to the end of the cantilever. Von Mises, maximum principal and minimum principal stresses were analysed. \u0000Results The results indicated a tendency towards stress reduction in Von Mises stress values of dental implants with the increase in diameter for both mesial and distal implants. In narrow implants active thread design resulted in lower Von Mises stress values than passive thread design. Active thread design demonstrated higher bone stress when compared to passive thread design. The analysis also revealed the importance of mesial implant for diminishing stresses on the distal implant and their surrounding bone under horizontal and oblique loading. \u0000Conclusion The comparison of the models suggest that use of wide implant is advantageous in the all-on-four concept. There is a biomechanical advantage in using narrow implants with active thread design in horizontally inadequate bone. The thread design was more significant in terms of increasing bone stress than implant diameter. The mesial implant influences the biomechanical behavior of the whole design, contributing to a more favorable stress distribution under horizontal and oblique loading conditions.","PeriodicalId":42724,"journal":{"name":"Journal of Osseointegration","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2021-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89429962","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}
