摘要： A dental instrument is provided for use in facilitated placement and fixation of dental veneers of fragile porcelain-based material or the like designed for bonding onto patient teeth. The instrument includes a lightweight handpiece adapted for coupling to a vacuum source, in combination with a disposable transparent tip designed to engage and conform with surface contours of a dental veneer for vacuum-holding of the veneer during manipulation preparatory to fixation. A valve port on the handpiece can be opened or closed with a fingertip or with a movable valve member to facilitate controlled pick-up and release of the dental veneer. The transparent tip enhances dentist vision during veneer placement and further permits passage of radiation for improved curing of a light curable bonding agent conventionally used for veneer fixation. A multipurpose vacuum source adapter and alternative instrument geometries are also disclosed.
