A 38 year old female patient, followed in the oral rehabilitation appointment at ISCSEM clinical university, came to the control appointment after the adhesion of feldspathic veneers of 13, 12 and 11, as well as total coating feldspathic ceramic crown adhesion in 21 tooth and a crown on the implant of 22. After intraoral examination, a wedge fracture of the crown of 21 was observed. The proposed treatment suggests the adhesion of a new total crown, however, the patient didn't want to be subjected to more appointments, so she opted for a faster solution. It was suggested to repair the veneer in mouth with composite resin. When adhesion is preferred over cementation, it becomes more difficult to replace the fractured crown, and conventional treatment for fractured veneers / crowns usually involves the destruction of the piece in its entirety. This substitution involves the repetition of the whole process, requiring the need for new and time-consuming appointments, both for the patient and for the medical dentist. The use of alternative therapies is essential if the patient is not willing to undergo this clinical process (veneer preparation, molds, photographs and a new adhesion appointment). As an alternative, mouth repair by infiltration with a loaded adhesive has been increasingly applied, leading to a longer life of this type of restorations, constituting a very viable, conservative and fast-applied alternative. With this therapeutic approach, a suitable aesthetic and functional result was achieved, saving chair time to the patient. Keywords: Ceramic crack, reparing, feldspatic crack
