COMPARATIVE EVALUATION OF CRESTAL BONE CHANGES IN IMMEDIATE PLACEMENT AND DELAYED PALCEMENT OF DENTAL IMPLANT : A CLINICO-RADIOGRAPHICAL STUDY

Abstract

Background : To compare crestal bone changes after placement of immediate versus delayed dental implant

Aim and Objective : Comparative evaluation of crestal bone changes in immediate placement and delayed palcement of dental implant: A clinico-radiographical study.

Methods : A coparative study was conducted in total 20 implant sites in patients within the age group 20-60 years comprising both male and female visiting Out-patient Department of Periodontology and Implantology ,D J College of Dental Science and Research Modinagar (U.P). Clinical parameters were recorded at baseline ,3 months ,6 months; they included pain, mobility, radiographic assessment for crestal bone changes.

Results : On intergroup comparison, the mean difference of the pain and mobility between Group A and GroupB showed that there was  no significant result. On intergroup comparison, the mean difference of the crestal bone changes between Group A and Group B showed that Group B had slightly higher bone loss than Group A during baseline to 6th month period.

Conclusion : Within limitations of this study, it can be concluded that there was significant crestal bone loss in Group A (Immediate implantation) at both mesial and distal surface during baseline to 6th month observation period. Furthermore, a continuous bone resorption was observed over the time in both the groups. Due to small sample size, short duration, and CBCT assessment of crestal bone loss during follow-up in the study long?term survival of two?piece implants in both the groups cannot be determined; so, further studies are required to be done.
