Abstract: The clinical application of the ultra-thin porcelain veneer specifically refers to the improvement of the aesthetic effect of teeth through the 0.3-0.5 mm-thick porcelain veneer on the basis of no or very small amount of tooth preparation，which has become the mainstream of aesthetic repair of anterior teeth. It is highly favored by patients because of the minimal damage to the teeth, and clinicians are increasingly concerned about the repair process and long-term efficacy of the ultra-thin porcelain veneer. In this paper, the clinical application of ultra-thin porcelain veneer will be discussed in detail from the development process, indications, tooth preparation and the selection of porcelain materials and adhesives.

Key words: ultra thin porcelain veneer, minimally invasive dental restoration, esthetic effect, clinical efficacy, all ceramic restorations
