Abstract

Purpose: The study evaluated the use of xenograft and hyaluronic acid mixture covered by amniotic membrane versus same mixture covered by collagen membrane on osseointegration of simultaneous implant inserted in mandible in expanded posterior alveolar ridge. Materials and methods: Twelve patients were divided equally and randomly into two groups. Group (A) was treated by xenograft and hyaluronic acid (HyA) covered by amniotic membrane (AM) after ridge expansion and implants insertion, while, at Group (B) collagen membrane (CM) was used as a coverage membrane. Implant stability was recorded at base time, 3, and 6 months after placement of implant. While, Marginal bone loss (MBL) and Bone mineral density (BMD) were measured at base time, 3, and 6 months postoperatively. Results: There was a significant higher ISQ values at third and six months postoperatively in group (A). Regarding MBL, the variance is not analytically significant between the intended groups. Regarding bone density group (A) showed a significantly increase at third and six months postoperatively. Conclusion: Application of xenograft and HyA with amniotic membrane was proved to improve and accelerate bone healing and osseointegration procedure for dental implants in term of: increased bone density, quantity, and improved bone quality and implant stability.
