Abstract a. Aim: This study is aiming to evaluate the quality and quantity of bone gain following Ridge augmentation in atrophic anterior maxillary ridges with titanium reinforced polytetraflouroethelene membrane versus collagen membrane with anorganic bovine bone derived mineral with and without particulated autogenous bone chips. b. Methodology: Twenty patients suffering from atrophic anterior maxillary ridges less than 5mm using polytetrafluroethylene membrane versus native collagen membrane both with a mix of (1:1) ratio of anorganic bovine bone derived mineral and particulated autogenous bone chips c. Results: collagen group has mean bone gain 4.3±0.39 if only successful cases are included and 3.88±1.54 with all cases included. PTFE group has mean bone gain 3.8±0.59 if only successful cases included and 1.92±2.51 with the all cases included. d. Conclusion: Complications associated with the non-resorbable PTFE membrane barriers regarding the considerable incidence of soft tissue dehiscence leading to large amount of graft loss is a matter of concern, so ptfe membranes should be covered with collagen membranes to avoid soft tissue complications specially in esthetic zone. |
