AIM: The present study was conducted to evaluate the effect of aloe vera gel on implant stability for implant assisted overdenture.

MATERIAL AND METHODS: Aloe vera gel high molecular weight fractions (AHM) containing native ingredients of polysaccharide (acemannan) and glycoprotein (verectin) were obtained by using the patented hyper dry system after washing out colored materials with running water from aloe vera gel slurry. Ten completely edentulous male patients aged from sixty to seventy years were selected from patients attending outpatient clinic of Prosthodontics department. Each patient had received two implants in the canine region for implant assisted overdenture. The study was conducted as split mouth study design in which the comparison was done between Group I: the right side of the patient in which the implant is inserted in the osteotomy site in conventional way and Group II: the left side of the patient in which aloe vera sponge was inserted in the osteotomy site before implant placement. All cases were received the overdenture at time of implant placement as immediate loading protocol and the implant stability was recorded and compared between Group I and Group II by OSSTELL device at time of insertion, six months, twelve months follow up periods.

RESULTS: There was an increase in the numerical implant stability quotient (ISQ) values for Group II over Group I during the follow-up period. However, the difference was statistically non-significant as P value was ≥ 0.005.

CONCLUSION: Aloe vera sponge shows promising results in its effect on the osseointegration and implant stability for immediate loading implant assisted overdenture that appear ISQ values during the follow up period.
