Seven implant sites were present per maxillary cast, corresponding to healed (right and left first premolars, left second premolar and first molar) and extraction sites (right canine and central incisors). The casts were assigned into three groups: freehand (FH), conventional closed-sleeve guide (CG) and surgical guide (SG) groups. Each group comprised 10 casts and 70 implant sites (30 extraction sites and 40 healed sites). Digital planning was used to design 3D printed conventional and surgical guide templates. The primary study outcome was implant deviation.Results: At extraction sites, the largest difference between groups occurred in angular deviation, where the SG group (3.80 ± 1.67 degrees) exhibited ~1.6 times smaller deviation relative to the FH group (6.02 ± 3.44 degrees; P = 0.004). The CG group (0.69 ± 0.40 mm) exhibited smaller coronal horizontal deviation compared to the SG group (1.08 ± 0.54 mm; P = 0.005). For healed sites, the largest difference occurred for angular deviation, where the SG group (2.31 ± 1.30 degrees) exhibited 1.9 times smaller deviation relative to the CG group (4.42 ± 1.51 degrees; P < 0.001), and 1.7 times smaller deviation relative to the FH group (3.84 ± 2.14 degrees). Significant differences were found for all parameters except depth and coronal horizontal deviation. For the guided groups, there were fewer significant differences between healed and immediate sites compared to the FH group.Conclusion: The novel sleeveless surgical guide showed similar accuracy to the conventional closed-sleeve guide.","PeriodicalId":73463,"journal":{"name":"International journal of oral implantology (Berlin, Germany)","volume":"16 2","pages":"117-132"},"PeriodicalIF":0.0,"publicationDate":"2023-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9438396","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}

The digital models were then imported into image analysis software, where an examiner (LM) performed a 3D surface defect map analysis characterising the buccolingual profile of the peri-implant tissues in respect to the adjacent teeth. Ten linear divergence points that were 0.5 mm apart in a corono-apical direction were identified at the midfacial aspect of the implants. Based on these points, the implants were grouped into three different buccolingual profiles.Results: The method for creating the 3D surface defect map of isolated implant sites was outlined. Eight implants displayed pattern 1 (coronal profile of peri-implant tissues more lingual/palatal than their apical portion), six implants exhibited pattern 2 (opposite of pattern 1) and six sites showed pattern 3 (relatively uniform and \"flat\").Conclusions: A novel method for assessing the buccolingual profile/position of peri-implant tissues using a single intraoral digital impression was proposed. The 3D surface defect map visualises the volumetric differences in the region of interest compared to the adjacent sites, allowing for objective quantification and reporting of profile/ridge deficiencies of isolated sites.","PeriodicalId":73463,"journal":{"name":"International journal of oral implantology (Berlin, Germany)","volume":"16 2","pages":"105-113"},"PeriodicalIF":0.0,"publicationDate":"2023-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9808189","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}

The research outcomes were complications, implant failure and peri-implant marginal bone loss.Results: The study population was composed of 35 patients with 103 extra-short implants placed after the failure of different reconstructive approaches. The mean follow-up duration was 41.3 ± 21.4 months post-loading. Two implants failed, leading to a failure rate of 1.94% (95% confidence interval 0.24%-6.84%) and an implant survival rate of 98.06%. The mean amount of marginal bone loss at 5 years post-loading was 0.32 ± 0.32 mm. It was significantly lower in extra-short implants placed in regenerative sites that had previously received a loaded long implant (P = 0.004). Failure of guided bone regeneration before placement of short implants tended to lead to the highest annual rate of marginal bone loss (P = 0.089). The overall rate of biological and prosthetic complications was 6.79% (95% confidence interval 1.94%-11.70%) and 3.88% (95% confidence interval 1.07%-9.65%), respectively. The success rate was 86.4% (95% confidence interval 65.10%-97.10%) after 5 years of loading.Conclusions: Within the limitations of this study, extra-short implants seem to be a good clinical option to manage reconstructive surgical failures, reducing surgical invasiveness and rehabilitation time.","PeriodicalId":73463,"journal":{"name":"International journal of oral implantology (Berlin, Germany)","volume":"16 1","pages":"31-38"},"PeriodicalIF":0.0,"publicationDate":"2023-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10824837","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}

{"title":"Papilla reconstruction using a vertical interproximal tunnel approach.","authors":"Muhammad H A Saleh, Istvan A Urban, Abdusalam Alrmali, Andrea Ravidà","doi":"","DOIUrl":"","url":null,"abstract":"Introduction: Papilla reformation is one of the most difficult and elusive surgical techniques for clinicians. Although it involves similar tenets to those applied for soft tissue grafting at recession defects, crafting a small tissue in restricted space remains unpredictable. Numerous grafting techniques have been developed to correct interproximal and buccal recession, but so far, only a limited number of techniques have been prescribed for interproximal remediation.Case presentation: This report describes in detail a modern technique (the vertical interproximal tunnel approach) for reforming the interproximal papilla and treating interproximal recession. It also documents three challenging cases of papilla loss. The first case presented Class II papilla loss and a recession type 3 gingival defect adjacent to a dental implant, managed using the vertical interproximal tunnel approach through a short vertical incision. A 6-mm increase in attachment level and almost complete papilla fill were observed in this case with this surgical technique for papilla reconstruction. The second and third cases presented Class II papilla loss between two adjacent teeth, managed using the vertical interproximal tunnel approach through a semilunar incision and achieving full papilla reconstruction.Conclusion: Both described incision designs for the vertical interproximal tunnel approach require technical meticulousness. When executed carefully and using the most beneficial pattern of blood supply, predictable reconstruction of the interproximal papilla can be achieved. It also helps alleviate concerns associated with inadequate flap thickness, blood supply and flap retraction.","PeriodicalId":73463,"journal":{"name":"International journal of oral implantology (Berlin, Germany)","volume":"16 1","pages":"55-64"},"PeriodicalIF":0.0,"publicationDate":"2023-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10824832","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}
