Partial veneer retainers

Abstract

lh’ 1s article is a discussion of partial veneer retainers, Specifically, three-quarter crowns and their modifications will be considered. Dentists should understand the basic preparation form, where this form could be used, and what modifications are available to meet most patient treatment situations. Partial veneer retainers may be used on anterior or posterior teeth of either arch where parallel proximal grooves of an adequate length and retentive walls and planes can be obtained to insure stability. Maximal retention with minimal sacrifice of tooth structure and encroachment upon the pulp is possible with this type of retainer. Esthetically, it can be acceptable in either anterior or posterior teeth. The retention attained with the partial veneer is comparable to that of a full cast crown provided that there is sufficient natural tooth structure remaining, and providing the preparation is properly made. All tooth surfaces are usually covered by these retainers except the labial or buccal surfaces of the maxillary teeth, and the mandibular anterior teeth. In mandibular molars, sometimes the buccal instead of the lingual surfaces are covered.
