Objective: To demonstrate the efficiency of Er:YAG laser for removal of laminate veneers in case of fracture. Primary modes of failure of porcelain laminate veneers were noted to be fracture, microleakage, or debonding.
Background Data: One of the predisposing factors for the occurrence of fractures is heavy functional or parafunctional loading.
Methods: Removal of fractured laminate veneers with Er:YAG laser is proposed as a reliable method. Two cases are presented in which fractured laminate veneers were removed with Er:YAG laser. The parameters used for removal were set at 20 Hz/320 mJ, with water irrigation for 9 sec and the chisel-type laser tip was selected (1.2×0.4 mm, rectangular shape). The pulse width was 200 ms.
Results: The laminates were removed without any damage to the underlying tissue. The new restorations were reconstructed and both patients were taken under recall program at 6-month intervals.
Conclusions: The removal of fractured laminate veneers with Er:YAG laser could be a suitable alternative in routine clinical use.

Purpose: This study is designed to explore the effect of Er,Cr:YSGG laser tooth etching versus that of conventional tooth surface treatment on the shear bond strength of ceramic laminate veneers.
Methods: Seventy-six maxillary premolars were assigned to two groups (n = 38) according to the type of enamel surface treatment approach. Group 1: samples treated with the conventional acid-etch protocol.

Restorative dentistry often uses ceramic laminate veneers for aesthetic anterior teeth restorations due to their natural appearance and minimal invasiveness. However, the understanding of their clinical performance and how ceramic microstructure and processing affect longevity is limited. This study aimed to address this gap by determining the mechanical behavior, fracture load, and failure modes of CAD-CAM processed laminate veneers made of either lithium-disilicate-based glass ceramic (IPS e.

The clinical success of laminate veneers depends upon their marginal discrepancy (MD) and internal gap (IG). This study aims to compare and evaluate the MD, overall discrepancy (OD), absolute marginal discrepancy (AMD), and IG of 3D-printed (Varseosmile TrinQ and Varseosmile Crown Plus) and computer-aided design and manufacturing (CAD/CAM)-milled (Brilliant Crios) laminate veneers using cone-beam computed tomography (CBCT). Thirty maxillary central incisors were prepared and divided randomly into three groups ( = 10).

Designing and fabricating dental restorations via the indirect method emerged as a strategic response to the loss of tooth coronal structure that prompted the need for different treatment options depending on the extent of the damage (eg, partial-coverage restorations such as inlays/onlays and laminate veneers, or full-coverage restorations such as crowns). The complexities of the oral environment and patient management in the dental chair also factored into the development of indirect restorations. Indirect restorations involve manufacturing them away from the oral cavity, avoiding some of the difficulties of direct techniques, such as polymerization contraction and marginal adaptation, as polymerization shrinkage stresses only affect the cement layer, reducing the impact on the cavity walls.
