Abstract Implant-supported removable partial dentures (ISRPDs), which can transform a tooth/tissue-supported mandibular Kennedy class I or II removable partial denture into a pseudo- Kennedy class III, have become a popular prosthodontic treatment option in recent years. Compared with conventional removable partial dentures (CRPDs), ISRPDs offer maximum denture stability and greater occlusal force, and facilitate functional recovery. ISRPDs also offer excellent maintainability, because they have removable superstructures. Additionally, ISRPDs have a high implant survival rate of 95 -100% and high patient satisfaction. On the other hand, mechanical complications, such as breakage or loosening of the implant attachments and fracture of the denture components, have been also reported with the use of ISRPDs. However, there is still no evidence- based research regarding the ISRPD. In terms of implant-supported complete overdnture, it was reported that the stress concentration on the residual ridge at the posterior ends of the mandible can be correlated with clinically measured bone resorption Within the limitation of this study the following could be concluded: 1. In case of loading on the implant ,the fixed partial denture design ,produce better load distripution followed by the cross arch partial denture design followed by the side plate over denture design . 2. In case of loading on natural abutment ,the cross arch partial denture design produce the least amount of strain followed by the fixed partial denture, then the side plate partial denture design. |
