Abstract
Aim: To evaluate the fracture resistance and color changes of ceramic laminate veneers
prepared with modified gull wing and conventional preparation
Methodology: Twenty -four ceramic laminate veneers were fabricated for maxillary
anterior teeth. The patients were divided into two groups according to the preparation
technique group 1(control group) conventional preparation technique and group 2
(intervention group) gull wing preparation technique . Standardized the same incisal
preparation with butt joint design and chamfer finish line located supra gingival were
performed for all the teeth. The veneers surfaces were treated and silanated according to
the manufacture instruction of each ceramic and enamel surfaces were etched where total
etch adhesive protocol was obeyed using BISCO. Fracture resistance and color change for
both groups were evaluated according to United States public health services (USPHS)
criteria.
Results: Fracture resistances and color change were evaluated according to the criteria of
USPHS and we found there is no significant difference as both groups scaled zero score.
Conclusions: Both preparation techniques of laminate veneers revealed high successful
clinical performance in terms of fracture resistance and color stability
