Introduction:
Depth of placement of implant shoulder in relation to the crestal bone positively influence bone remodelling and preservation but the role of placement depth on bone loss before loading is not very clear.
Aim:
To assess the effect of placement depth alone on the crestal bone loss around implant placed at subcrestal and equicrestal level before prosthetic loading.
Materials And Methods:
Patients reporting to the Department of Prosthodontics with the complaint of missing teeth were enrolled in the study after analysing inclusion and exclusion criteria. A total of 24 implants were planned to be placed into two groups as Group E (n=12) and Group S (n=12). Follow up radiographs after implant placement and after six months were analysed for the amount of bone loss.
Results:
On six months follow up crestal bone levels of Group E were apical to Group S. Bone loss comparison between groups after six months follow up, revealed almost same mean bone loss.
Conclusion:
The implants placed at subcrestal and equicrestal level did not show difference in crestal bone loss before prosthetic loading.
