November 15, 2025 updated by: Nesma mousa, Mansoura University

Comparative Study Between Digital Pick-up of Attachments Before Registration of Jaws Relations and Intraoral Pick-up With Digitally Constructed 2-Implant Mandibular Overdenture Bases : Peri-Implant Alveolar Bone Height Changes

Comparing digital attachment pickup prior to jaw relation registration with intraoral pickup using digitally constructed mandibular overdenture bases is the aim of this study.
