There is disclosed a standardized system for the preparation of an area of a tooth for fitting a dental veneer, and the subsequent installation of the dental veneer onto the tooth, in the prepared area. The system uses a grinding oscillating tip, which is specific for a prefabricated or stock veneer, the prefabricated or stock veneer corresponding to the shape of grinding tip (the tip has the shape of the prefabricated or stock veneer).

Ultrasound oscillation can be propagated to a distal end of an elongated probe. A cross-sectional surface of the probe is perpendicular to the length of the probe, and has to the same shape as a shape of a cross-sectional surface of an anchor. The probe is configured to forma bottomed hole in a bone for placing the anchor and the shape of its cross-sectional surface can prevent rotation of the anchor in the bottomed hole. An area of the cross-sectional surface of the probe at the distal end can be larger than an area of a cross-sectional surface of the probe at a proximal end. The distal end of the probe includes a treatment portion that extends outward from a center of the proximal end of the probe in a first direction perpendicular to the longitudinal direction and in a second direction different from the first direction.

A piezoelectric device comprising: (a) a handpiece for holding by a user; (b) a cutting insert for said handpiece; (c) an ultrasound transducer disposed within the handpiece, the ultrasound transducer capable of providing first and second ultrasound frequency vibrations to the cutting insert in response to an electrical signal; and (d) a switch allowing the user to control the electrical signal and thereby provide either said first or second ultrasound frequency vibrations to the cutting insert.
The device is useful in a method of placing an implant into an implant site comprising cutting overlying gingival tissue at a first ultrasound frequency capable of cutting soft tissue, then switching to a second ultrasound frequency capable of cutting the underlying jawbone.

An ultrasonic system includes generator means for ultrasonic microvibrations; waveguide means connected to and extending away from the generator means to bend at least in part; an operating element joined to a stationary bending node, so that flexural microvibrations are transmitted by the waveguide means to the operating element as alternating torsional or flexural microvibrations.

A light transmitting probe for use in endodontic procedures comprises a light transmitting core and a metallic sheath surrounding said core. The metallic sheath defines a reflective inner surface. The probe further includes a plurality of apertures formed in the sheath, such that light can exit said probe through the apertures.
