Facially Driven Digital Workflow for Maxillary and Mandibular Milled Implant- Retained Overdentures Using Two Different Unsplinted Attachment Systems: Case Report

Compend Contin Educ Dent. 2023 Nov-Dec;44(10):574-580.

Abstract

Unsplinted attachment systems for implant overdentures offer various benefits for edentulous patients, including cost-effectiveness, enhanced cleansability, and less need for manual dexterity. This article describes a facially driven digital workflow for fabricating a maxillary implant overdenture retained by conometric-style attachments (Atlantis® Conus) with a palateless design opposing an implant overdenture retained by standard attachments (LOCATOR®). This procedure provides a predictable and accurate technique to digitally scan the master casts with wax rims for articulation and to guide the digital teeth design set-up for a predictable esthetic outcome. The removable prosthesis workflow involves virtual teeth set-up, a 3D-printed trial denture, a milled definitive prosthesis, and intraoral pick-up for both unsplinted attachment systems. The clinical and laboratory steps are described.
