Tissue Regeneration | Bone Grafting CATEGORY DESCRIPTION
Whether used to replace autogenous bone entirely or expand autogenous grafts, bone substitute materials (BSM) must be effective for time-delayed procedures before dental implant insertion and for recipient site optimization at the time of implant placement (simultaneous procedures). Fixation devices such as guided bone regeneration membranes, collagen membranes, titanium mesh, and bone screws may be used to counteract mechanical stresses on the graft during healing.
The most commonly used alloplastic graft materials are calcium phosphate-based ceramics such as hydroxyapatite (incompletely resorbed) and tricalcium phosphates (completely resorbed). Bioactive glass is more reactive than these materials, and promotes bone regeneration by releasing silica ions. Over time, it is fully absorbed and, when mixed with autogenous bone graft material, bioactive glass doubles natural bone regeneration. One newer alloplastic material is made to be syringed directly into the defect and, in many cases, eliminates the need for a matrix.
Different types of BSMs can be combined and even hybridized, allowing for a wide range of resorption rates in formulations such as powders, granules, pastes, blocks, and custom manufactured grafts.
Resorbable and nonresorabable barrier membranes (natural biomaterials, collagen, synthetic polymers) exclude undesirable cell types while creating and maintaining space, providing clot stabilization, and allowing tissue integration.
For some patients, bone augmentation is the only way they can get an implant or partial dentures. Some patients are not candidates for autogenous bone harvesting. So the next best thing may be the highly biocompatible Puros Block Allograft from Zimmer Biomet. This sterile-packaged block of corticocancellous bone can be implanted in the either...
The term “good corporate neighborhood” is used by a lot of companies to market themselves to their communities and customers. But I always wonder how many put that phrase into action. Richmond Dental and Medical, a division of Barnhardt Manufacturing Company based in Charlotte, NC, did just that recently when they made a 3-year commitment to...
The foundation of a great restoration is a great impression and the key to a great impression lies in tissue management. When it comes to both taking impressions and seating restorations, adequately retracting gingival tissue and maintaining hemostasis minimizes problems and promotes a positive outcome. By taking several considerations into...
Dr. Christopher Lugo was facing administrative challenges to the growth of his multi-location practice, Puget Sound Pediatric Dentistry. Faced with administrative redundancies and inefficiencies, he knew something had to change. In April 2013, Dr. Lugo and his staff made the decision to invest in Dentrix Enterprise, allowing the practice to...
