Effect of Retention Sil Versus Ball and Socket Attachment on the Supporting Structures of Implant retained Mandibular Overdentures

Abstract

Introduction: Introduction of dental implant retained overdentures in the field of dentistry improves retention and stability of dentures and improve function when compared to conventional dentures, therefore implant retained overdenture is considered the first treatment option for mandibular edentulous patients which mainly complain from instability of their mandibular dentures. Aims: This study radiographically assesses the effect of retention sil versus ball and socket attachment on the supporting structures of mandibular implant retained overdentures. Materials and Methods: Fourteen completely edentulous patients were selected from the outpatient clinic Faculty of Dentistry, Ain Shams University according to the following criteria: Results: All the selected patients were rehabilitated by mucosa supported maxillary complete denture and implant retained mandibular overdenture. Patients participating in this study were randomly divided into two equal groups according to the type of attachment: Group I: Patients were received lower implant retained overdenture relined with " Retention Sil " soft liner. Group II: Patients were received lower implant retained overdenture with ball and socket attachment. Conclusion: Patient rehabilitation with implant retained overdenture using retention sil had a better effect on bone resorption compared to the effect of ball and socket. Recommendation: Based on the results of this study, it was recommended to carry out the same study but regarding to the difference in the retentive value between ―Retention Sil‖ material and ball and socket attachment.
