High-resolution cone-beam computed tomography (CBCT) scans were obtained before flap closure, after primary closure, and following simulated soft-tissue movement in order to analyze graft material thickness at multiple predefined levels along the implant surface.

In dehiscence defect morphologies, graft thickness decreased significantly over time, with the greatest dimensional changes occurring immediately after primary wound closure (GEE main effect of TIME, &lt;i&gt;p&lt;/i&gt; &lt; 0.001). In these defects, pronounced coronal (platform level) graft displacement was observed, with thickness reductions of approximately 1.2–1.4 mm after closure and total reductions exceeding 85% following simulated soft-tissue movement. Barrier membrane application did not prevent graft collapse nor modify the coronal temporal pattern; however, it resulted in a limited attenuation of graft loss at selected middle levels (approximately 0.15–0.25 mm, corresponding to 5%–15% relative reduction). In 2–3 wall defects, graft thickness also decreased significantly over time across all evaluated levels (&lt;i&gt;p&lt;/i&gt; &lt; 0.001), with membrane application consistently attenuating early graft displacement at coronal and middle levels.

The SC was fabricated from four materials:(1) yellow resin (SC-YR), (2) gray resin (SC-GR), (3) white resin (SC-WR), and (4) titanium alloy (SC-TA). Each SC group was attached to the model and scanned 10 times with an intraoral scanner (IOS). The resulting intraoral scans were calibrated using desktop scans of the SCs as references. A desktop scan of the model served as the overall reference dataset. Each test scan, as well as the reference scan, was processed to contain only six SB–SRA assemblies. The processed test scans were superimposed onto the reference scan by: (1) using all six SBs to evaluate the overall fit, and (2) using the first and second SBs to simulate the virtual Sheffield test. Following superimposition, trueness was evaluated by calculating the linear deviation between the centers of the six SRAs in each test scan and the corresponding centers in the reference scan.

In the subset of 32 implants with available CBCT data, horizontal bone width and vertical bone height changes were minimal in both buccal and palatal/lingual aspects. Subgroup analyses indicated that guided bone regeneration provided measurable advantages in preserving bone dimensions at specific sites, particularly in the mid-buccal region and the palatal/lingual vertical height. However, at most other reference points, dimensional changes were comparable irrespective of whether GBR was performed.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusion</h3>\u0000 \u0000 <p>A novel implant featuring a machined long neck exhibited clinically acceptable outcomes with respect to implant survival, implant success, and bone dimensional stability over a one-year follow-up period.</p>\u0000 </section>\u0000 </div>","PeriodicalId":50679,"journal":{"name":"Clinical Implant Dentistry and Related Research","volume":"28 2","pages":""},"PeriodicalIF":4.0,"publicationDate":"2026-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12997391/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147476705","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
