TWO-STAGE LATERAL SINUS LIFT
Access to the sinus cavity is gained by preparing a window at the lateral aspect of the maxillary sinus, preferably with a diamond burr or piezo instrument. Following detachment of the Schneiderian membrane, the created space is filled with a bone grafting material (e.g. cerabone®, maxgraft® or maxresorb®). In order to promote an undisturbed healing, the sinus window may be covered with a collagen membrane (e.g. collprotect® membrane). After a healing time of about six months, the treated site has sufficient bone volume for the placement of one or more implants.
