COMPARISON OF DELAYED VERSUS IMMEDIATE LOADING OF DENTAL IMPLANTS IN PARTIALLY EDENTULOUS MANDIBULAR POSTERIOR REGION

Abstract

Study Design: 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 compare to delayed loading implants for replacing missing natural teeth. The aim of this study is to compare the effect of immediate and delayed loading of implants in partially edentulous mandibular posterior region and to analyze outcome of both techniques Objective: To compare and evaluate postoperative treatment outcome in mandibular posterior region clinically and radiographically. Method: This is a Randomized controlled study, consisting of 50 patients. They were divided in two groups. Group1 (Number of patients- 25, Delayed loading implant) and Group2 (Number of patients-25, Immediate loading implant). Soft tissue examination were measured by probing depth with William probe , Hard tissue were measured and compared using OPG/CBCT and IOPAR. Result: The difference in the bone loss between Group A and Group B was 0.02 mm. In respect to soft tissue healing of gingiva bucally, lingually and papilla the average score of mean modied sulcus bleeding index and mean modied plaque index was not more than 01, signifying mild inammation at the most. Primary stability increases in both the groups. In delayed group mean stability was 56 and in immediate group mean stability was 57 which was adequate at the time of surgery and during healing period. The mean bone healing score was higher in delayed group than that of immediate group but the difference failed to reach the level of statistical signicance. Conclusion: Our study concludes that whether it is immediate loading or delayed loading protocol, under appropriate circumstances, medical condition and maintenance of good oral hygiene provide similar success rate.
