Midterm-evaluation of a prospective 5-year clinical study on long-term performance and success rate of pressed-ceramic veneers with two extended preparation designs.
There is little agreement regarding a palatal extension of the preparation for porcelain veneers, as it represents a more invasive technique than a preparation limited to the facial surface of a tooth.
The authors reviewed and identified the evidence for the various incisal preparation designs for ceramic veneers.

However, limited information is available regarding the influence of preparation design on longevity of ceramic veneers.
A novel technique was exploited for preparation of thick finely fluffed poplar veneers (FFPVs).
Innovative preparation designs, like those for porcelain laminate veneers, are much less invasive than conventional complete-coverage crown preparations.
Beech (Fagus orientalis) and alder (Alnus glutinosa) veneers having 1.8 mm thickness were used in the preparation of panels.
Ceramic veneers and resin-bonded prosthesis retainers were the least invasive preparation designs, removing approximately 3%to30%0% of the coronal tooth structure by weight.
Main objective of this study is to investigate the thermal behavior of ceramic laminate veneer restorations of the maxillary central incisor with different incisal preparations such as butt joint and palatinal chamfer using finite element method.
