Lateral sinus lift - one stage
The reliability and high predictability of grafting materials for the sinus lift procedure are well documented. Among these, cerabone® is an excellent bovine grafting material. Its particles serve as an osteoconductive scaffold for osteoblasts and support new bone formation starting from the margins of the defect. Moreover, cerabone® particles integrate into the new bone with only minor superficial resorption over the years and therefore guarantee a long-term volume stability of the grafted site.
As an alternative, synthetic grafting material maxresorb® or the allogenic maxgraft® granules may be used; particularly suited for minor grafting procedures (<4 mm to augment), synthetic easy-to-apply paste maxresorb® inject is also a valid option.
Placement of a Jason® fleece prior to the application of relatively sharp bone graft granules can protect the Schneiderian membrane from damage and offers a cost effective alternative to a barrier membrane. If a smaller perforation of the Schneiderian (<5 mm) membrane is already present, then the use of a collagen membrane (e.g., collprotect® membrane) is recommended to seal the perforation.
Despite the scientific debate about the need for a barrier membrane, several studies have demonstrated that the use of a membrane to cover the sinus window results in a higher success rate for the sinus lift procedure. Thus, these study clearly indicate that a brarrier membrane should be applied to ensure an undisturbed healing. Particularly indicated for this purpose is the medium-term barrier function of collprotect® membrane. If an additional lateral augmentation is needed (for instance, due to a reduced ridge width), it is recommended to cover the augmentation site with a slowly resorbable membrane. The Jason® membrane, with its long-term barrier function, can stabilize the augmentation site for a sufficiently long period, thus ensuring an undisturbed osseous regeneration.
