ABSTRACT:
Background: Aging, maxillofacial trauma, periodontal disease, cysts, lesions and ablative surgery can result in decreased alveolar bone volume. In the maxilla, limited bone quantity and quality, especially in the posterior region results in low success rates for dental implants. In the mandible, inferior alveolar nerve position complicates the possibility of reconstruction using dental implants. Various methods for bone augmentation have been described such as conventional techniques utilizing autografts and allografts. Lately the use of CAD/CAM technology is rising among different professions including maxillofacial surgery. In-house planning is becoming more abundant and has its advantages.
Methods: Different methods utilizing CAD/CAM technology will be presented. These include 3D planning of reconstruction and guided surgical aids for accurate placement of conventional, pterygoid and zygomatic implants. Nerve lateralization and guided implant placement will be presented.
Results: 90% of the implants have undergone proper osseointegration, no significant bone loss was observed and reimplantation was performed or is planned. Soft tissue healed properly with normal probing pocket depth. Successful implants were prosthetically restored.
Conclusions: CAD/CAM enable us to adapt the the surgical result to a more predictable and prosthetic oriented and functional results, resulting in better longevity of the implants and the restoration functions as ideally as possible.
