However, EMS with conventional techniques may result in esthetic concerns, such as gingival recession, papilla loss, and soft tissue scarring, especially in patients with high esthetic demands. This manu-script describes a dual-layer flap preparation approach that utilizes an external coronally advanced flap (CAF) and an internal trapdoor periosteal flap (TPF) for EMS in the esthetic zone. The external CAF is a split-full-split-thickness flap that allows the gingival margin to be coronally advanced over the cementoenamel junction or prosthetic margin to mitigate any potential gingival recession due to flap retraction or to treat existing gingival recession. The internal TPF is the periosteal elevation of the partial-thickness tissue that remained after the elevation of the external CAF. The internal TPF employs vertical release(s) to obtain adequate access for periapical surgery. Sites treated with this approach healed with no complications, minimal patient discomfort, no facial recession or loss of papilla, and minimal soft tissue scarring. Therefore, the dual-layer flap preparation approach is suggested as a viable flap design for EMS in the esthetic zone.","PeriodicalId":94231,"journal":{"name":"The International journal of periodontics & restorative dentistry","volume":"0 0","pages":"554-565"},"PeriodicalIF":1.1,"publicationDate":"2026-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144015535","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 study compared the trueness and repeatability of twelve digital impression systems (DIS), including nine intraoral scanners (IOS) and three stereophotogrammetric (SPG) systems, for a fully edentulous maxilla restored with eight multi-unit abutments (MUAs). Accuracy was assessed using a coordinate measuring machine-derived reference model and a clinically driven 'worst-MUA' approach, considering the suprastructure as a single functional unit. Trueness and repeatability were evaluated along vertical (Z), horizontal (XY), three-dimensional, and angular dimensions across five repeated acquisitions per system. Significant variability in both trueness and repeatability was observed among DIS. Median trueness deviations ranged from 0.009-0.042 mm (Z), 0.027-0.117 mm (XY), 0.026-0.107 mm (3D), and 0.140°-0.427° (angular). Median repeatability deviations ranged from 0.0014-0.0230 mm (Z), 0.0015-0.0380 mm (XY), 0.0016-0.0372 mm (3D), and 0.0217°-0.1558° (angular). Principal component analysis identified three performance clusters: high-performing systems (Itero Lumina, Imetric 4D, Shining 3D scan, Primescan2), intermediate systems (Shining 3D photogrammetry, Medit i900, Primescan, Panda Eletra, Medit i700, Nobel Fast Map), and low-performing scanners (Trios5, Trios6). Errors were more pronounced at terminal arch positions, on MUAs #1 and #8. These findings highlight the system-dependent nature of digital impression accuracy and demonstrate that several next-generation intraoral scanners achieved accuracy levels comparable to those of photogrammetric systems under the standardized in vitro conditions of this study.","PeriodicalId":94231,"journal":{"name":"The International journal of periodontics & restorative dentistry","volume":"0 0","pages":"1-29"},"PeriodicalIF":1.1,"publicationDate":"2026-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148893235","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}

Calibrated evaluators assessed KMW and MT, standardized intraoral photographs, and intraoral scans (IOS) obtained from adult patients with non-molar implant-supported prostheses. Diagnostic accuracy was determined using sensitivity, specificity, predictive values, diagnostic odds ratios (DOR), and receiver operating characteristic (ROC) curve analysis. Inter- and intra-observer agreement were assessed using Fleiss' kappa, weighted kappa, and intraclass correlation coefficients (ICC). Based on sample size calculation, a total of 60 patients with 60 non-molar implant-supported prostheses were included. Twenty calibrated evaluators with different professional backgrounds assessed 140 digital images, with 20 images repeated. This resulted in 2800 KMW and 2800 MT evaluations. Overall, a limited ability to distinguish inadequate from adequate KMW and thin from thick MT was shown when assessing digital images. Photographs tended to be associated with slightly higher sensitivity and specificity than IOS, with overall sensitivity ranging from 31.3% to 56.9% and specificity from 45.6% to 63.7% across modalities. ROC analysis confirmed poor discriminatory capacity for both imaging modalities, with area under the curve values ranging from 0.427 to 0.633. Inter-observer agreement was generally fair, whereas intra-observer reproducibility remained poor across evaluator groups and imaging modalities. In conclusion, visual assessment of peri-implant KMW and MT based on digital imaging demonstrated limited diagnostic accuracy and reproducibility compared with direct clinical measurements.","PeriodicalId":94231,"journal":{"name":"The International journal of periodontics & restorative dentistry","volume":"0 0","pages":"1-35"},"PeriodicalIF":1.1,"publicationDate":"2026-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148893243","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 case report describes its expanded use for ridge augmentation at the time of extraction when immediate implant placement is not indicated. The esthetic buccal flap was used for ridge augmentation in three patients with significant maxillary anterior hard tissue defects. At the time of implant placement, which was delayed five to six months, soft tissue augmentation was performed to enhance esthetic outcomes. After provisionalization, final restorations were delivered, and esthetics were assessed using the modified Pink Esthetic Score (mPES). All three cases obtained mPES scores of 9 or 10, which indicates excellent soft tissue contour, symmetry, and integration. Within the limitations of this case report, these results indicate that the esthetic buccal flap is a minimally invasive, soft tissue preserving technique that can be adapted to treat complex alveolar ridge defects. In combination with newer biomaterials and the use of a delayed implant procedure, this strategy provides predictable results for regenerative as well as esthetic success in difficult anterior cases.","PeriodicalId":94231,"journal":{"name":"The International journal of periodontics & restorative dentistry","volume":"0 0","pages":"1-23"},"PeriodicalIF":1.1,"publicationDate":"2026-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148893206","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}

Composite resins excel in minor or localized cases-such as class III and IV cavities, minor contour modifications, or closure of small diastemas-owing to their straightforward application, color-matching capabilities, and minimal tooth preparation requirements. However, they are vulnerable to issues like discoloration, wear, and marginal staining, and they often need periodic repolishing or repair. Dental ceramics demonstrate superior longevity, color stability, and resistance to wear, making them the preferred choice for extensive rehabilitations, larger restorations, and compromised teeth requiring crowns or bridges. While ceramics generally involve more invasive preparations and demand meticulous bonding procedures, their inert nature and high mechanical strength often result in outstanding long-term outcomes when properly executed. Clinical decision-making should account for factors such as tooth structure, occlusion, patient age and habits (eg, parafunctions), staining risk, and esthetic demands. Ultimately, striking the right balance between biology, function, and esthetics is essential to avoiding overtreatment and preserving natural dentition. Through illustrative case studies and a synthesis of relevant literature, this article provides practical guidelines for selecting the most appropriate material for each clinical scenario.","PeriodicalId":94231,"journal":{"name":"The International journal of periodontics & restorative dentistry","volume":"0 0","pages":"70-81"},"PeriodicalIF":1.1,"publicationDate":"2026-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144328294","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}
