The Reported Complications of Milled Ceramic Anterior Veneers with at Least One Year Follow Up: A Systematic Review.

Abstract

Purpose: To assess the available evidence regarding survival and failure rates of ceramic anterior veneers constructed utilising CAD/CAM technology, with a follow-up period of at least one year.

Materials and methods: A comprehensive electronic search was performed through Medline (Ovid), Embase, and Web of Science. The search was limited to articles published from 1970 to January 2023 and, included articles were human cohort clinical studies and randomised control trials.

Results: A total of 9,449 articles were retrieved, 5,943 studies were screened and 22 were assessed for eligibility, resulting in 4 studies that met the inclusion criteria. A total of two failures were recorded, the failures involved fracture of the veneers, from a total of 1037 veneers in the included studies. No other failures were noted.

Conclusions: Studies demonstrating long term survival of CAD/CAM made ceramic veneers are limited. This study shows the clinical outcomes are favourable over the short term. Given the short observation periods reported, further long-term studies are required to obtain a better understanding of the clinical outcomes and restoration survival.

Clinical relevance: The article assists clinicians with providing an update on the available evidence when considering CAD/CAM constructed ceramic veneers on anterior teeth.
