Abstract: No-preparation ceramic veneers have become the choice of clinicians and patients under certain circumstances although their indications and material selections are limited. Previous studies indicated that the short-term clinical performance of no-preparation ceramic veneers was similar to that of traditional ceramic veneers, with lower preoperative mental tension and postoperative sensitivity but fair marginal adaption. No-preparation technique preserves the entire enamel thus increases the bonding strength of the restorations and fracture resistance of the tooth. The internal adaptions are not perfect since some minor undercuts are not removed. However, there is no consensus on the occlusion design and clinical protocol of no-preparation veneer of no-preparation veneer. Although no-preparation technique has been proposed, more clinical randomized controlled trials should be performed to obtain consistent results.
