Partial ceramic crowns. Esthetic and tissue conservative restorations...

What is it about?

Background: For anterior teeth with large defects or for teeth which need major changes in color, shape or size, laminate veneers are a highly esthetic and comparatively tissue conservative treatment option within a large group of other therapeutic measures. The survival rates of laminate veneers are > 90% over 10 years and in the range of full coverage crowns. For patients with heavy bruxism and/or small clinical crowns the longevity may be reduced. Objective: to review the main guidelines for dental treatment using laminate veneers.Data Sources: dental literature (Web of Science, PubMed, Google Scholar) about laminate veneers between 1998 and 2019. Study Selection: articles, reviews and textbooks about laminate veneers were selected to obtain the most relevant information. Data Extraction: all data evidence-based about laminate veneers technique were extracted. Data Synthesis: all data considered important and relevant for the laminate veneers technique were presented step by step in a coherent and concise way. The conclusions were:•Preparation should be as conservative as possible (0.3 – 0.5 mm cervical-buccal reduction). •Special methods for impression taking and for temporization should be applied. •The ceramic material needs to have optimal esthetic properties including adequate translucency. •The choice of the luting material is based on optimal bonding (etch & rinse, SE). Solely light curing luting composite materials or flowable composites can be used for optimal and long-lasting esthetics for ceramic thickness of up to 1 mm. •In order to protect the laminate veneers against parafunctional forces during night sleep a protective splint (night guard) is recommended.
