Full-arch restoration of the jaw with fixed ceramometal prosthesis

Between 1990 and 1995, 214 implants were placed in 29 maxillae and mandible s of 22 patients following extraction of all residual teeth as a consequenc e of severe periodontal disease. All patients were discharged wearing immed iate dentures. The implants were analyzed with regard to the number per arc h, location, length, and diameter. The 5-year cumulative survival rate was 98.5%. The mean number of implants per arch was 7.5 for the maxilla and 7.2 for the mandible. The preferred implant locations were canines, central in cisors, lateral incisors, and second premolars in the maxilla; and lateral incisors, first molars, and canines in the mandible. The mean implant lengt h was 14.7 mm in the mandible and 14.5 mm in the maxilla. The mean implant diameter was 3.8 mm in the maxilla and 3.8 mm in the mandible. The results of the present study indicate that immediate implantation for fixed full-ar ch reconstruction can be considered a viable treatment alternative in patie nts with severe periodontal disease.
