chirurgia maxillo facciale

 
 

Pre-prosthetic surgery, pre-implantology and implantology

Modern oral surgery and dentistry involve a number of complex procedures, such as implanting titanium fixtures directly into the bone, which requires detailed pre-surgical planning. The purpose of this planning is to determine whether the quantity and quality of bone is sufficient to provide anchorage for a serviceable restoration, and to avoid damaging sensitive structures such as nerves. Pre-surgical planning must be based on highly accurate imaging to be effective. Computed tomography is increasingly employed to plan dental implant surgery because of its accuracy, sensitivity, and freedom from geometrical distortion. The latest generation of CT scanners can image the complete mandible or maxilla in under one minute, delivering high spatial resolution in both the transaxial and the paraxial directions at low radiation doses. To be successful, implantology requires both permanent integration of the titanium fixture into the bone, and good aesthetic restoration of the teeth and gums. The procedure requires close colaboration of the implant surgeon, the restorative dentist and the dental laboratory technician. Detailed pre-operative planning is therefore extremely important. In case of transversal or vertical atrophy, bone grafts taken from the patient or by using biocompatible tissue, prepare the maxilla-mandibular bone for implants.
