CBCT imaging with less radiation and high spatial resolution can provide a comprehensive evaluation of endo-perio lesions. A total of 71 teeth with endo-perio lesions were assessed using CBCT. Periodontal bone defects were studied for bone loss pattern (horizontal/vertical) along with bone loss levels on mesial and distal sides in association with furcation involvement. The periapical lesions were studied for their prevalence and extent based on CBCT PAI Score. Horizontal and vertical bone loss were detected in 54 teeth (76.1%) and 17 teeth (23.95%), respectively. Mean crestal bone loss levels on mesial and distal aspects were 4.80 ± 3.21 mm and 5.74 ± 3.91 mm, respectively. The mean height, width, and depth of furcation defects were 3.19 ± 2.99 mm, 1.94 ± 0.98 mm, and 4.44 ± 1.92 mm, respectively. Periapical lesions were recorded in 55 teeth (77.5%). A CBCT PAI score of 5 was scored in 35 teeth with a mean lesion diameter of 11.3 ± 2.83 mm, while 16 teeth had healthy periapical tissues (scores of 0 and 1). CBCT is a valuable diagnostic tool that can help assess endo-perio lesions by providing morphometric measurements of periodontal bone defects and the extent of associated periapical lesions.","PeriodicalId":54948,"journal":{"name":"International Journal of Periodontics & Restorative Dentistry","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2023-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9957468","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed approach combined immediate implant placement with buccal tissue enhancement by applying a crosslinked collagen matrix hydrated with crosslinked hyaluronic acid (xHyA). All 10 cases presented with a retained but narrow buccal socket wall, so immediate implant placement with the \"tunneled sandwich\" technique was performed after tooth extraction. The tunneled sandwich technique helped create a subperiosteal pouch for insertion of the collagen matrix buccal to the alveolar bone crest. The implants healed transmucosally by receiving either a gingiva former or an immediate temporary restoration. Ten sites in 10 patients demonstrated stable, noninflamed peri-implant conditions and suitable ridge volume at the implant neck and achieved high pink esthetic scores 6 months after implant loading. The tunneled sandwich technique is a suitable method to preserve buccal volume, which biologically and esthetically contributes to favorable long-term results.","PeriodicalId":54948,"journal":{"name":"International Journal of Periodontics & Restorative Dentistry","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2023-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9596389","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 34 patients with 156 implants were selected for this study: 18 patients underwent tooth extraction on the day of implant placement (Group D), and 16 patients were already edentulous (Group E). A periapical radiograph was taken at a mean follow-up of 9 years (range: 5 to 14 years). Success and survival rates and the prevalence of peri-implantitis were calculated. Statistical analysis was used to assess comparisons between groups. After a mean follow-up of 9 years, the cumulative survival rate was 97.4% and the success rate was 77.4%. The difference between the initial and final radiographs resulted in a mean marginal bone loss (MBL) of 1.3 ± 1.06 mm (range: 0.1 to 5.3 mm). No differences were seen between Groups D and E. Peri-implantitis affected 15 implants (9.6%) in 9 patients (26.5%).

This case report describes an alternative modified two-stage presplitting technique. The patient was referred for an implant-supported rehabilitation of their edentulous mandible. CBCT scans showed a mean available bone width of about 3 mm. At the first stage, four linear corticotomies were performed using a piezoelectric surgical device. At the second surgical stage 4 weeks later, bone expansion was performed, and four implants were placed in the interforaminal area. The healing process was uneventful. No fractures of the buccal wall and no neurologic lesions were observed. Postoperative CBCT scans showed a mean bone width gain of about 3.7 mm. Implants were uncovered 6 months after the second surgery, and 1 month later, a fixed provisional screw-retained prosthesis was delivered. This approach could be used as a reconstructive technique that avoids using grafts and reduces treatment times, possible complications, postsurgical morbidity, and costs by exploiting the patient's native bone as much as possible. Considering the limitations of a case report, randomized controlled clinical trials are needed to confirm the results and validate this technique.","PeriodicalId":54948,"journal":{"name":"International Journal of Periodontics & Restorative Dentistry","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9655622","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study assessed the validity of Cone Beam Computed Tomography (CBCT) and transgingival probing.Methods: Patients presenting with APE were assessed. Transgingival probing was performed to clinically assess the distance between the cementoenamel junction (CEJ) and the crest of the bone at the mid-point of upper anterior teeth. CBCT was used to assess this distance at the same point. Upon reflection of a full mucoperiosteal flap the actual distance was measured.Results: Similar actual and CBCT measurements of the distance between the CEJ and bone crest at upper right 3, upper left 2 and upper left 3 (P>0.05) were recorded. However, in upper right 2, upper right 1 and upper left 1 the distance was significantly greater on CBCT (P<0.05). No significant difference was detected between transgingival probing and the actual distance at all teeth assessed.Conclusions: Careful transgingival probing provides an accurate measure of the distance between the CEJ and crest of the Bone. CBCT gives an accurate estimate, However, it might not be justified for each patient in the presence of safer methods.","PeriodicalId":54948,"journal":{"name":"International Journal of Periodontics & Restorative Dentistry","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9680361","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The external oblique ridge is the most-used donor site for bone plate harvesting, followed by the mandibular symphysis. The lateral sinus wall and the palate have also been described as alternative donor sites. This preliminary case series reports a bone shell technique that used the coronal segment of the knife-edge ridge as a bone shell in five consecutive edentulous patients (20 sites) with severe mandibular horizontal ridge atrophy and adequate ridge height. The follow-up period was 1 to 4 years. The average horizontal bone gains at 1 mm and 5 mm below the newly formed ridge crest were 3.6 ± 0.76 mm and 3.4 ± 0.92 mm, respectively. Ridge volume was sufficiently restored in all patients to enable implant placement in a staged approach. In 2 of the 20 sites, additional hard tissue grafts were required at implant placement. The advantages of utilizing the relocated crestal ridge segment are as follows: The donor and recipient sites are the same, no major anatomical structures are compromised, periosteal releasing incisions and flap advancement are not required for primary wound closure, and the risk of wound dehiscence is minimized due to reduced muscle tension.","PeriodicalId":54948,"journal":{"name":"International Journal of Periodontics & Restorative Dentistry","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9662076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fourteen consecutive patients, requiring replacement of a single hopeless maxillary or mandibular tooth, meeting the clinical and radiographic indication criteria for immediate implant placement, were treated. All cases followed the same digitally-guided procedure of extraction and immediate implant placement. Immediate temporization with full contoured screw-retained provisionals was performed using an integrated digital workflow. After implant placement and dual-zone bone and soft tissue augmentation, connecting geometries and emergence profiles were finalized. The average implant insertion torque was 53.2 ± 14.9 Ncm and ranged between 35 and 80 Ncm, allowing immediate provisional restoration in all cases. Final restorations were delivered three months after implant placement. An implant survival rate of 100% was observed at the 1-year recall after loading. The results of this case series suggest that immediate placement of novel tapered implants and immediate provisionalization using an integrated digital workflow can result in predictable functional and esthetic results for the immediate transition of failing single teeth in the esthetic area.","PeriodicalId":54948,"journal":{"name":"International Journal of Periodontics & Restorative Dentistry","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9655620","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
