Background: Guided tissue regeneration (GTR) is a common treatment modality for correcting vertical or bony defects in furcations. Multiple materials are used in GTR with allografts and xenografts being the most widely used. Each material has distinctive properties affecting the regenerative potential. A new bone graft combination of xenogeneic/allogeneic may improve the outcome of GTR by providing space maintenance (Xenograft) and osteoinductive potential (Allograft). The aim of this case report is to evaluate the efficacy of the new combined xenogeneic/allogeneic material based on clinical and radiographic outcomes. Methods: A 34‐year‐old healthy male presented with vertical bone loss interproximally between #'s 9 and 10. Clinical exam revealed 8 mm probing depth without mobility. The radiographic exam revealed a wide and deep vertical bony defect of 30%–50% bone loss. The defect was treated using a layering technique with xenogeneic/allogeneic bone graft and collagen membrane. Results: The 6‐ and 12‐month follow‐ups revealed a significant reduction in probing depths and radiographic bone fill. Conclusions: GTR using a layering technique of xenogeneic/allogeneic bone graft and collagen membrane showed proper correction of a deep and wide vertical bony defect. The 12‐month follow‐up revealed healthy periodontium with normal probing depths and bone level. [ABSTRACT FROM AUTHOR]

Introduction: Alveolar bone deficiency is a common postextraction sequela that adversely affects implant placement. Therefore, ridge augmentation is often required to obtain proper bone quantity and quality for restoratively driven implant placement. This case series describes the successful horizontal and vertical alveolar ridge augmentation using custom‐fabricated allogeneic block bone grafts. Case Series: Two healthy partially edentulous patients presented to private practice seeking dental implant treatment. Initial clinical examination and cone‐beam computed tomography (CBCT) radiographic analysis showed moderate to large horizontal ridge defects. Treatment options were discussed for alveolar ridge augmentation and the patients elected to undergo the custom allogeneic block graft procedure to regenerate the atrophied alveolar ridges. The CBCT scan in conjunction with computer‐aided design/computer‐aided manufacturing (CAD/CAM) technology was used to fabricate customized allogeneic block grafts based on alveolar ridge topography. The custom allogeneic block graft allowed less surgical time and decreased postoperative morbidity. The grafted area was allowed 6 months of healing time. Follow‐up radiographs showed the stability of the graft followed by dental implant placement. The dental implants were functionally loaded, and successful implant esthetics and function achieved. Conclusion: Custom allogeneic block grafts could provide a promising innovative method for optimal ridge augmentation. Why are these cases new information?Less invasive procedure as an alternative conventional two‐stage block augmentation.More predictable outcome due to customized block graft. What are the keys to successful management of these cases?It is important determining the type of bone defect.Vertical and horizontal bone loss.Primary closure. What are the primary limitations to success in these cases?Limited data from prospective clinical trials documenting the effectiveness of custom allogeneic block grafts.Limited data are available to confirm accuracy of the CAD/CAM process.Passive flap closure is needed.

Introduction: Peri‐implant infections can occur any time postloading. Although management of peri‐implant infections has been described extensively in the literature, no consensus exists on the best approach to its treatment. Infections and bone loss can also occur around implants prior to loading, leading to early implant loss. Little has been reported on the management of peri‐implant infections occurring prior to loading. This report describes the identification as well as the surgical and restorative management of infection and bone loss around a preloaded dental implant. Case Presentation: A 52‐year‐old systemically healthy, non‐smoking white female had severe inflammation with bleeding on probing and bone loss around implant #28 (Universal Numbering System) 7 weeks after placement and augmentation with autogenous and deproteinized bovine bone and a resorbable collagen membrane (RCM). Surgical exposure revealed a deep bony crater around the entire implant. The implant was cleaned for 4 to 5 minutes with a tetracycline and saline slurry. Guided bone regeneration was performed with demineralized freeze‐dried bone allograft and an RCM. Azithromycin, ibuprofen 800 mg three times daily, and 0.12% chlorhexidine gluconate rinse were given post‐surgery. Postoperative healing was uneventful. Nearly complete bone fill was noted at 1 year of observation when implants were permanently restored. A combination of screw‐ and cement‐retained restorations were placed. Tissues remained healthy 5.5 years postloading with maximum 3‐mm probing depth and no changes in bone levels. Conclusions: This case shows that it is possible to arrest early peri‐implant infection, regenerate bone, and maintain health over 5.5 years postloading. Early detection and multidisciplinary care resulted in long‐term success. [ABSTRACT FROM AUTHOR]
