The aims of this clinical study are:
To evaluate the clinical performance between indirect composite and ceramic laminate veneers:
Main interests are:
* colour stability of the restoration (digital measurement in follow up)
* failure mode of the restoration
* wear of the restoration and antagonist
Hypothesis:
* The colour stability of indirect composite restorations will not be different from the ceramic restorations.
* The indirect composite restorations will not be more prone to failure than the ceramic restorations.
* Antagonist wear and restorative material wear will be similar for both ceramic and composite.
Material and Methods The laminates will be fabricated according to a specified protocol. In order to avoid possible noticeable differences in case of distinct levels of possible discoloration, a modified split mouth design is employed where the central incisors and the symmetric other teeth receive the same type of restoration. Randomization is based on the paired teeth and it is performed using the flip of a coin for the choice of material. Evaluation will be performed at baseline and at follow-up visits annually up to 2 years.

Inclusion criteria
✓. The veneers will be placed on central incisors, lateral incisors, canines in the maxilla. Indications will involve replacing worn, discoloured composite restorations and existing veneers, or correcting discoloured, malformed and/or misaligned teeth.
✓. An indication for closure of the open space (diastema)
✓. No obvious untreated caries, dental health problems (regularly checked by a dentist).
✓. No untreated periodontal disease (allowed are DPSI 1, 2, 3-)
✓. Good or moderate oral hygiene (plaque score of less than 30% in anterior region before treatment).
✓. Endodontic treatment with good outcome (root canal densely filled with gutta-percha 0.5-1.5 mm from apex) with only a restoration on palatinal side.
✓. The patient agrees with the research protocol (signing of an agreement form, appendix 4)
