Abstract

A literature review was carried out on indications, contraindications, advantages and protection of direct veneers with composite resin, which is of fundamental importance, so that the Dental Surgeon obtains information to assist the patient in order to restore form, function and aesthetics, developing the harmony of the smile, self-esteem and sociability. Its indication must take into account the diagnosis, adequate planning, mastery of the surgical technique, oral hygiene, parafunctional habits, periodontal, orthodontic and financial aspects, positioning of the teeth such as rotations or crowding and darkening, finishing and polishing procedures, resulting in less roughness, biofilm accumulation, absence of periodontal damage, improved longevity of the restoration and resistance to dye impregnation, promoting the mimicry of the tooth structure. Providing reduced clinical time, preservation of dental and periodontal tissues, immediate aesthetic results, easy maintenance and clinical longevity. They are a great treatment option in cases of diastema, teeth reanatomization needs and correction of dental fractures. The direct technique has difficulties in execution, such as the work being performed inside the oral cavity and presenting salivation, difficulty in adequate absolute isolation and limitation of mouth opening. The limitations of the material, as well as the operators, mean that the longevity of the rehabilitation treatment with indirect veneers is greater when revealed with direct veneers. The association of the direct technique with bleaching, reverse planning, the mock-up and the silicone guide, allows for great predictability of the final result, providing favorable aesthetics.
