Evaluation of Primary Stability in Immediate Loading of Dental Implants

Abstract

Study Design: With the patient’s desire to shorten the treatment time and to avoid an edentulous condition, immediate loading of implants has emerged as an alternative approach as compared to delayed loading implants for replacing missing natural teeth. The aim of this study is to evaluate the primary stability in immediate loading of dental implants. Objective: To evaluate primary stability and postoperative complications clinically and radiographically. Method: Total 50 patients were treated with immediate loading dental implants. Withdrawal criteria includes patients not returning for checkup, follow-up, or documentation, and patients not following postoperative instruction. Result: Primary stability increases in immediate loading protocol; mean stability was 57 which was adequate at the time of surgery and during healing period. Conclusion: Our study concludes that under appropriate circumstances, medical condition and maintenance of good oral hygiene provide better primary stability in immediate loading protocol.

“…In replicating the immediate loading conditions observed in clinical settings, most studies use a frictional contact state at the implant-bone interface, employing a friction coefficient of 0.3 to simulate the non-osseointegration state [ 35 , 36 ]. However, relying solely on this approach falls short of fully replicating the clinical conditions of immediate loading protocols, and the significance of initial stress cannot be ignored [ 37 , 38 ]. Primary stability represents a mechanical occurrence marked by the anchoring force generated from the mechanical interaction between an implant and the adjacent bone tissue.…”
