title: An Alternative Design to Overcome the Problem of Unfavorable Implant Angulations for a Screw-Retained, Implant-Supported Fixed Prosthesis: Two Clinical Reports.
abstract: Two clinical reports present an alternative design to address the problem of unfavorable implant angulations if a screw-retained prosthesis is desired. The restorations were designed as screw-retained prostheses, except in the area with the unfavorable implant screw emergence. The frameworks in these areas were customized to receive individual cement-retained crowns. This design offers retrievability and helps to minimize complications associated with excess cement without compromising the functional or esthetic outcome.
