Approaching bone defects of jaws treatments, hard and soft tissue augmentation could be considered as a goal for clinicians when performing dental implant placement. The increase in patients who want cosmetic treatment puts practitioners in an awkward position when choosing the best therapy to obtain the most desirable results.
A private dentist referred a young patient to the Department of Implantology in Milan in order to place implants in the upper jaw. Radiographic evaluation of the two upper anterior incisors confirmed that the teeth had a poor prognosis The anterior ridge volume was clinically analyzed and several therapeutic choices were evaluated. Rapid extractions and immediate implant positioning were not considered due to the vertical and horizontal components of the bone defect. Therefore, the surgical team decided on increasing the bone volume by using slow orthodontic teeth extrusion technique.
After 3 months of orthodontic treatment, the angular intra-bony defects of 1.1 tooth was completely healed. Implant guided positioning, associated with a small bone graft, showed optimal results at the time of healing screw placement. The soft tissue conditioning was obtained by a provisional acrylic crown. The final application of two integral ceramic crowns showed excellent aesthetic results. Radiographic investigation at a 24 month follow-up confirmed the integration of the dental implants and the recovery of the bone defects.
Several safe surgical techniques are available today for reconstructing atrophic jaws. However, the same technique applied on the posterior area did not give the same predictable results as in the anterior areas of the jaw.
