Prospective Outcomes of Guided Equator Overdentures

NCT07196943 · Status: RECRUITING · Type: OBSERVATIONAL · Enrollment: 40

Summary

This prospective clinical study evaluated the 3-year performance of mandibular implant-supported overdentures (IODs) placed using a fully guided static computer-assisted implant surgery (CAIS) protocol. Primary outcomes included implant survival, peri-implant soft tissue health, and marginal bone loss. Findings provide evidence for the predictability of digital surgical workflows in removable prosthodontics.

Interventions

DEVICE

Fully guided static computer-assisted implant surgery (CAIS) for mandibular overdentures using Equator® attachments

Mandibular edentulism will be rehabilitated with implant-supported overdentures using a fully guided static computer-assisted implant surgery (CAIS) protocol. Each patient will receive four implants placed in a quadrilateral configuration (lateral incisor and first premolar regions) under a stereolithographically manufactured surgical guide. Following 3-4 months of osseointegration, definitive mandibular overdentures will be fabricated and retained exclusively with Equator® attachment systems (Rhein 83, Bologna, Italy). Patients will be followed for 3 years to assess implant survival, peri-implant soft tissue health, and marginal bone changes.
