Purpose:
The purpose of this study was to investigate the effect of Bio-Gide in MGBR (membrane guided bone regeneration ) in the anterior maxilla dental implant therapy.
Methods:
Fifty five cases underwent dental implant therapy in the anterior maxilla with insufficient maxillary anterior bone, including 29 patients with embedded 40 implants using MGBR and 26 patients with embedded 40 implants without using MGBR. The condition of bone around implant before implantation and before final restoration was observed and recorded. The thickness of the bone was measured with vernier caliper, the density and the bone loss were determined by X-ray examination. The results were analyzed with X-ray radiographs image analysis system (Sidexis) and SPSS16.0 software package.
Results:
Univariate analysis showed that there was significant difference in the thickness and the density of the bone between before implant operation and before restoration(P<0.05). There was significant difference between the thickness and the density of the bone between with and without MGBR(P<0.05).
Conclusions:
These results suggest that the thickness and the density of the bone in the group with MGBR is better than the group without MGBR. It is recommended to use MGBR in dental implant therapy in the anterior maxilla with insufficient bone.
