Immediate Restoration of Dental-Implants in Periodontally Treated Patients, Interim Results

Objectives: to evaluate implant and patient characteristics in a prospective clinical study involving immediate restoration of dental implants. Methods: Patients, diagnosed with generalized chronic periodontitis and previously treated, were accepted into the study when expressing their wish to receive immediate restoration of dental implants. Treatment planning and installation was computer assisted, using a CT, planning software and a surgical template. Patients received abutments and cemented provisional prostheses 72 hours following implant surgery and were followed up after 10 days, 4 weeks, 3 and 6 months. Results: 18 patients were included, aged between 34-69 years (mean 54 years). 5 patients were smokers, with 2.5-60 packyears. 50 implants were installed, ranging between 1-8 implants per patient. Implant length was 10-13mm (median 13 mm) and diamenter 3.75-5 mm (median 3.75mm). Mean insertion torque was 43 NCm ± 6.2 SD, range 30-50 NCm. Mean ISQ was 71 ± 11, range 37-85. 1 implant in 1 non smoking patient and 3 implants in 1 smoking patient failed for a total of 4 failed implants. 6 month survival rate was 92%. Conclusions: Survival of immediately restored dental implants in periodontally treated patients fall within the literature range.
