« to course overview
For dental rehabilitation using endosseous implants, augmentation of the hard tissue is often necessary to restore the aesthetics and function of the masticatory apparatus over the long term. The donor region is determined according to the resorption levels; vascularized grafts are indicated for extensive defects. Skeletal anomalies also require orthognathic surgery.
8A.1 Augmentation of the maxillary posterior region by sinus floor elevation
Augmentation of the floor of the maxillary sinus by sinus floor elevation enables the prerequisites for inserting implants of sufficient length into the maxillary posterior region to be fulfilled. After exact prosthetic planning, these can be positioned in the center of the masticatory force. With precise planning, sinus floor elevation is a safe and reliable method for implant insertion in the posterior maxilla, which can be performed under local anesthesia. Potential complications can be easily managed. More than 90% of inserted implants are reliably and permanently osseointegrated.
8A.2 Extensive augmentation with iliac crest grafts
For dental rehabilitation with endosteal implants, bone augmentation is often necessary to ensure long-term restoration of aesthetics and masticatory function. The donor region is determined based on the degree of bone atrophy; for extensive defects, vascularized pedicle grafts are indicated. In patients with skeletal anomalies, orthognathic surgical measures are additionally required. If no other treatment option (e.g., short implants, zygomatic implants, or a fixed bridge on four angulated implants) is possible, iliac crest grafts represent a viable alternative.
