Implementation of Digital Dentistry to Rehabilitate a Mutilated Dentition With Implant Fixed Prostheses: A Clinical Report

Figure 1. (a, b) Failed restorations, missing teeth, and irregular occlusal plane were present and contributed to compromised esthetics. Figure 2. Radiographic examination showed supereruption of the mandibular anterior segment, proximity of the inferior alveolar nerve canal to the alveolar crest, and defective restorations. Figure 3. Mandibular alveoplasty reduction guide and mandibular bone-supported surgical guide for implant (Surgiguide) were fabricated by Materialise Dental Inc. Figure 4. Eight implants were surgically placed in the maxilla using a bone-supported surgical guide (Surgiguide).

Figure 5. (a) Preoperative view of the mandible. (b) The reduction guide showed the amount of bone that needed to be removed. (c) The mandibular anterior alveoplasty was performed using the mandibular reduction guide. (d) Six implants were surgically placed using the SurgiGuide. Figure 6. Panoramic radiograph showed the implants after placement. The mandibular distal implants were angled distally to avoid the inferior alveolar nerve and minimize the cantilever.
