Contornos y perfil de emergencia: Aplicación clínica e importancia en la terapia restauradora

Abstract

Close attention to both soft and hard tissues around teeth and implants before, during, and after restorative procedures will greatly increase the probability of a successful outcome. Crown contours are normally determined by tooth anatomy, periodontal condition, margin placement, and access for oral hygiene. However, compromises must occasionally be made in the interest of aesthetics. Proper restorative contours require adequate tooth reduction to allow proper thickness of restorative materials, while allowing easy access for personal oral hygiene. The emergence profile of a restoration in aesthetic areas has two aspects: subgingival form and supragingival form. The subgingival form should follow the contours of the cementoenamel junction and support the gingival tissues. Within limits, increased thickness of interproximal subgingival contours leads to increased papillary height, while increased facial contours lead to apical positioning of the gingival tissues. These and other clinical aspects must be known by the dentist when wishes to make a successful restoration.
