Purpose: Immediate restoration of dental implants in patients with a history of periodontal disease was examined. The influence of insertion torque and implant stability quotient (ISQ) on the survival rate was compared in immediately restored, nonrestored, and submerged implants. Materials and Methods: Patients received periodontal treatment after which all in one implant surgery was performed: hopeless teeth were extracted, debridement around remaining adjacent teeth was performed, implants were inserted and, in some cases, a prefabricated screw-retained provisional restoration was immediately delivered. Insertion torque and ISQ were recorded at baseline and 6 and 12 months postsurgery. Results: Nineteen patients were treated, and 74 implants were placed. Twelve implants, 10 of which were maxillary, failed in 4 patients. Survival rates were 100% in partial-arch restorations, 94% in the mandible, and 78% in the maxilla. The survival rate of restored implants was 65% in extraction sites versus 94% in healed, nonextraction sites. Implants exhibited a decrease in ISQ at 6 months followed by an increase at 12 months. There were no statistically significant differences in insertion torque or ISQ between failed and successful implants, restored and nonrestored implants, or extraction-site and nonextraction-site implants. Mandibular implants demonstrated higher insertion torque and higher ISQ at baseline and 6 and 12 months. Conclusions: Within the limits of this study, immediate restoration of dental implants in periodontally susceptible patients had a variable success rate. Several factors were shown to affect these results. (Comparative Cohort) Keywords: dental implants, immediate loading, periodontal disease
