Evaluation of Retention of Different Attachment System used in Implant Retained Overdenture
Journal Title: Journal of Advanced Medical and Dental Sciences Research - Year 2018, Vol 6, Issue 4
Abstract
Background: Dental implants are widely used nowadays. The most common problem associated with the management of edentulous patients is the severely resorbed mandibular ridge, especially in older age when adaptive capacities are reduced. The present study was conducted to evaluate retention of different attachment system used in implant retained overdenture. Materials & Methods: The present study was conducted in the department of Prosthodontics. It comprised of edentulous mandibular models which were made with heat cured polymethyl methacrylate resin. Acrylic resin mandibular overdentures were fabricated and provision was made to receive three different overdenture attachment systems, prefabricated ball/o ring attachment, Hader bar and clip attachment and locator implant overdenture attachment stud type. Each of the models were subjected to 100 pulls each to dislodge the overdenture from the acrylic model. Results: Group I comprised of prefabricated ball/o ring attachment, group II Hader bar and clip attachment and group III locator stud type implant overdenture attachment. In group I, mean force (N/cm) BT was 55.11 and AT was 50.24, in group II, BT was 72.26 and AT was 66.04, in group III, BT was 42.10 and AT was 36.01. The difference among BT and AT in all groups was significant (P< 0.01). Conclusion: Attachment may determine the success of implant supported overdenture. Ball O ring and Hader bar clip attachment proved to be better in terms of retention in compariosn to locator type of attachment.
