CASE REPORT

32-year-old male patient presented dissatisfaction with his smile due to several interdental spaces in the upper anterior teeth. The presence of diastemata was noted in the region of the central, lateral and upper canines.

TREATMENT
Due to the search for an immediate solution to the patient’s case and a good oral hygiene condition, ceramic veneers were chosen to improve the smile with: four veneers (12 to 22) and two ceramic fragments (13 and 23).

STEP BY STEP

Initial condition of the case after supragingival scraping followed by prophylaxis and shade taking.

Mock-up teeth were installed in order to provide the patient with a preview of the final esthetic result, with the possibility of minor adjustments and corrections. The preparations were carried out on the mock-up in position with the aid of silicone guides that allowed the precise and conservative wear necessary for the ceramics. These guides allow checking of the worn thickness in different regions, avoiding the unnecessary removal of healthy structure.

No-prep veneers and ceramic fragments on the plaster model, in vestibular and palatal view, followed by dry proof of pieces for adaptation check.

After acid etching, the veneers received and application of silane and the teeth were also etched.

The dental adhesive Ambar APS, which is colorless and does not interfere in the final color of the veneers, was applied to the teeth. Then, the cement Allcem Veneer APS was applied to the inner surface of the veneers, which were carefully layed on the teeth. Excess cement was removed with a disposable microapplicator.
