COMPARATIVE STUDY OF BAR, POSITIONER AND BALL ATTACHMENT IN SOLITARY VERSUS SPLINTED IMPLANT ASSISTED MANDIBULAR OVERDENTURE (IN VITRO STUDY)

Introduction: The conventional treatment for completely edentulous patients is complete denture. But can have substantial difficulties using their dentures due to a lack of retention, support, and stability the related compromise in chewing ability. Endosseous implants been shown be valuable rehabilitation these patients. To enhance retention denture, various overdenture attachments systems used mandibular implant overdentures. Aim study: aim this study evaluate prosthesis with different number attachment systems. Materials Methods: model was two groups according implants. Group A loaded canine region. B four region second premolar Each group divided into three subgroups positioner, bar & ball. Retention evaluated by universal testing machine. Results: It observed that there statistically significant difference between systems, as showed higher retentive force value mean = 101.47 ± 25.04 compared locator =55.53 15.98 ball 52.71 12.56. P ≤ 0.05. Conclusion: favourable attachment, overdenture. Keywords: Implant overdenture, Bar Ball Locator
