Influence of the preparation technique on the cervical contour of ceramic laminates: a case report

Abstract

Introduction: Due to the growing aesthetic demand, restorative dentistry is renewed in the intention of achieving better results in smile harmony. However, attention should also be turned to periodontal tissues, since there is an integration between restorative material and tissues. Objective: Describe and discuss the clinical steps for the manufacture of laminate veneers, paying attention to minimally invasive preparations, cervical contour and factors that can intervene in the longevity of the procedure. Case report: A 28-year-old male patient attended the Brazilian Dental Association – ABO, section of Alagoas, reporting dissatisfaction with the size of his teeth. The upper and lower arches were molded to obtain the study and diagnostic waxing models. At the beginning of treatment, the patient was instructed by the combined technique. After the case, the occlusal adjustment was performed, asking the patient to perform laterality and protrusion movements. Conclusions: The preparation technique influences the longevity of laminate veneers, due to adherence and periodontal health. The preparation should be minimal and limited to dental enamel whenever possible, thus determining a higher and better prognosis.
