The anatomic proximity of the maxillary sinus to the apices of molar and premolar teeth is a significant factor when considering implant therapy to replace maxillary posterior teeth. An emerging field within tissue engineering is the application of xenografts capable of stimulating de novo bone regeneration. This presentation presents a technique using a crestal approach to sinus grafting utilizing a novel bone graft material composed of porcine, ribose cross-linked collagen seeded with a microscopic hydroxyapatite mineral. This highly cohesive biomaterial is able to minimize graft migration, which is particularly important in case of undetected Schneiderian membrane perforations. The material also has been demonstrated in animal studies to be capable of osteoconduction, resulting in increased bone volume in ridge augmentation procedures.
1. Understand the advantages of a ribose cross-linked collagen based bone graft for crestal sinus elevations.
2. Selection of appropriate cases for simultaneous implant placement and crestal sinus elevations
3. Demonstrate the various applications, based on a published classification system, that crestal sinus elevation can be performed.
4. Appreciate the incidence of sinus membrane perforation when performing crestal sinus elevations, and recognize the need for a cohesive bone graft to minimize complications.
5. Differentiate the methods of collagen cross-linking and the advantages of ribose cross linking (GLTMATRIX®).
The webinar will include interactive Q&A during the last 10-15 minutes of the session.
