Resonance Frequency Analysis for Immediately Placed Dental Implants Replacing Periapically Infected Teeth

Aims: There is a controversy regarding the indication of implant insertion into sockets infected teeth. This study aimed to evaluate outcome immediate implants replacing periapically teeth utilizing Resonance Frequency Analysis (RFA) method. Materials and Methods: Preoperatively, clinical, radiographic examination accomplished for patients. After anesthetizing surgical area, accused tooth extracted, socket curetted by curette remove periapical lesion then irrigated normal saline solution. The inserted its prepared site. Beta-tricalcium phosphate (β-TCP) (combined collagen membrane) used fill gaps ≥ 2 mm repair bone defects. Implant stability quotient (ISQ) values were measured during surgery after 16 weeks. Postoperative clinical evaluation conducted each patient. Results: Fourteen out 41 (34.1%) had been in extraction have chronic lesions (infected sites), T-test showed no significant difference (ISQ value) between placed non-infected sites neither at baseline nor 16-weeks. Paired t-test highly increase while other mean ISQ value increased with healing period. success rate was 100% 4 years implantation. Conclusions: Presence not contraindication place when properly managed can provide similar survival that healthy sockets.
