Efficiency of Ridge Expansion Using Screw-Type Expanders with Simultaneous Trabecular Implant Placement in Narrow Anterior Maxilla (A Clinical and Radiographic Study)

Abstract

Background: Bone augmentation of narrow residual alveolar ridges in anterior maxilla is mandatory for better esthetical results. Many attempts were done to achieve acceptable outcomes including bone expansion. Using screw-type expanders is an acceptable treatment modality, complication-free and less sensitive technique. With the increase of esthetic demands, it was the importance of implant’s early loading which depends on its modified surface. The aim of this study was to evaluate clinically and radiographically the efficiency of placing Trabecular Metal Material implants with bone expansion in narrow anterior maxilla.Materials and Methods: For this clinical trial, 20 patients requiring implant placement in the narrow anterior maxilla of sufficient bone height and of ridge width ≥ 3mm but < 6mm were selected. Bone expansion using screw-type expanders was performed with simultaneous placement of Trabecular Metal Material implants. The studied variables were the degree of facial swelling, marginal bone height and bone width. The follow-up period was six months. For statistical analysis, Friedman and Wilcoxon tests were used.Results: A Significant decrease regarding marginal bone height and a significant increase regarding bone width were observed through the follow-up stage, while no significant difference was noticed concerning the degree of facial swelling when compared to base line measurements.Conclusion: The results assured the efficiency of bone expansion using screw-type expanders with simultaneous placement of Trabecular Metal Material implant and highlighted their promising effects concerning esthetical considerations.
