The secondary outcomes included evaluation of histologic composition of the filled alveolus, changes in soft tissue thickness and clinical parameters and implant primary stability. Thirty subjects requiring a non-molar extraction and delayed implant placement were randomized into two groups receiving either a combination demineralized/mineralized putty allograft (DMP) or a synthetic calcium phosphosilicate putty alloplast (CPS) and covered with an acellular dermal matrix allograft (ADM) as a barrier membrane. Cone-beam computed tomography (CBCT) scans were used to measure ridge dimensional changes at two timepoints: before extraction and 4 months after ARP. At re-entry for implant placement, a trephine core sample was taken for histologic analysis. Implant stability quotient (ISQ) values were used to record implant stability. The CPS group showed a mean decrease from 8.60 ± 1.97 mm to 6.47 ± 2.11 mm (mean change: -2.13 mm [-25.2%], p < 0.001), while the DMP group decreased from 7.83 ± 1.49 mm to 6.55 ± 1.88 mm (mean change: -1.28 mm [-16.0%], p = 0.009). Histologic evaluation showed a statistically significant higher percentage of mineralized tissue (MT) in the DMP group (38.2%) compared to the CPS group (20.2%) (p = 0.004). Both putty grafts effectively preserved ridge dimensions and facilitated implant placement.

Integrating digital tools and techniques has significantly advanced bone regen-eration and augmentation procedures, offering new possibilities to address these challenges effec-tively. This case series and technical report presents a method for transporting cortical bone blocks and evaluating the bone gain at reentry. It introduces a transporter guide designed to facilitate the precise placement of cortical bone plates and improve surgical outcomes. Six cases were evaluat-ed to assess graft stability, complications, and postsurgical bone augmentation. Computer-aided design and 3D-printing manufacturing were utilized to develop surgical guides for bone harvesting, transporter guides, and biomodels, optimizing the adaptation and fixation of cortical plates. Post-operative CBCT scans demonstrated minimal discrepancies between planned and achieved out-comes, with the mesial region showing greater variation than the distal area. The transporter guide streamlined the surgical workflow and reduced intraoperative errors. These findings suggest that the transporter guide facilitates safer, more predictable outcomes for the SBBT by reducing surgical complexity and improving the precision of graft positioning and stabilization.","PeriodicalId":94231,"journal":{"name":"The International journal of periodontics & restorative dentistry","volume":"0 0","pages":"574-589"},"PeriodicalIF":1.1,"publicationDate":"2026-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144032973","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}

A 44-year-old nonsmoking Japanese woman presented with discomfort in the mandibular left first molar. A Nabers probe was used to assess furcation involvement, and horizontal probe penetration from the midlingual to distolingual region of the furcation was observed. CBCT revealed a distolingual RE with significant bone destruction around it, indicative of a through-and-through furcation defect. A treatment approach known as vital root resection, which combines vital pulp therapy and surgical root resection, was implemented. First, deep pulpotomy was performed using mineral trioxide aggregate. Surgical root resection performed 8 weeks later resulted in a marked reduction in the pocket depth and resolution of the furcation defect. Clinical and radiographic evaluations at the 3-year follow-up demonstrated a stable periodontal condition and preserved pulp vitality, highlighting the effectiveness of this approach. This conservative treatment may be particularly relevant for Asian populations, in whom the prevalence of RE is up to 40%. Although the initial results are promising, further research with larger sample sizes and extended follow-up periods is necessary to establish standardized protocols and evaluate the long-term predictability of this technique.","PeriodicalId":94231,"journal":{"name":"The International journal of periodontics & restorative dentistry","volume":"0 0","pages":"566-573"},"PeriodicalIF":1.1,"publicationDate":"2026-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144004493","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}

All instruments were sharpened by a single operator using a standardized stationary instrument with the moving stone technique. Root planing was then performed on mounted extracted teeth. Using optical profilometry, surface roughness was quantified. Results showed that fine-grit abrasives produced smoother cutting edges and root surfaces compared to coarse-grit abrasives (P < .05). Curettes sharpened with the extra-fine diamond card yielded the lowest roughness on both the instrument edge and the root surface. The orientation of the sharpening card influenced outcomes, with a vertical orientation resulting in a significantly smoother edge than a horizontal orientation. Sequential sharpening, using fine and then extra-fine cards, further reduced edge and root roughness compared to the use of only a single fine-grit card. These findings highlight the importance of using extra-fine-grit sharpening tools and a proper sharpening technique to produce a smooth root surface.","PeriodicalId":94231,"journal":{"name":"The International journal of periodontics & restorative dentistry","volume":"0 0","pages":"636-649"},"PeriodicalIF":1.1,"publicationDate":"2026-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144546736","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}
