[Indications for supragingival preparation of teeth for placement of fixed prostheses]

Supragingival preparation offers simple controllable preparational procedure without contact of boring machine with gingive. That is the way to avoid the initial lesion of marginal parodont. The exactivity of leaning of the crown edge is visible. The control of generation of a carious initial lesion is in domain of patient--the carer and doctor. The esthetic aspect of work is not endangered by placing the crown of teeth of molar and premolar regions. The position of the edge of a crown makes possible the complete control and carrying out the measures of oral hygiene. The usage of monocomponent esthetic resins can solve the question of esthetic moment in the area of cement fissure. Supragingival location of the crown edge makes possible the inspection control of preparational border, the edge closing, esthetics in the tooth area and initial carious lesions.
