The invention relates to glass-ceramics based on the lithium silicate system which can be mechanically machined easily in an intermediate step of crystallisation and, after complete crystallisation, represent a very strong, highly-translucent and chemically-stable glass-ceramic. Likewise, the invention relates to a method for the production of these glass-ceramics. The glass-ceramics according to the invention are used as dental material.

A multifunctional dental liner applicator dispenses tooth liner and a stream of air while illuminating the working dental area. The applicator includes a body and a head that is removably attached to a distal end of the body. The head supports a nozzle that is configured to be inserted into a void of a prepared tooth. A liner button on the body controls a valve for dispensing liner out of the nozzle. An air button controls airflow out of openings adjacent the nozzle for drying an area that is receiving liner. Fiber optic fibers extend from a button controlled light source housed in the body to openings adjacent the nozzle for illuminating the working area.

A dental appliance is described herein. The dental appliance includes an abutment device adapted to be coupled to a jawbone and a sensor support assembly coupled to the abutment device. The sensor support assembly includes a sensor chamber that is configured to receive a sensing device therein. A chamber cover is coupled to the sensor support assembly to enclose the sensor chamber. The chamber cover includes a plurality of orifices that are configured to couple the sensor chamber in flow communication with an oral cavity. A tooth cap is coupled to the abutment device and includes a cap opening to receive the sensor support assembly therein.

The present invention to a method of denture manufacture that incorporates CAM-formed occlusal portions made of zirconia, resulting in a natural fit, feel, and wear essentially similar to the wear properties of natural teeth.

Dental preparation uses a tooth preparation guide custom-made liar fitting with teeth of a patient. The preparation guide includes one or more guide channels for guiding a cutting tool. The preparation guide enables modification of the teeth as planned with high level of precision. A dental prosthesis for installing onto prepared teeth of the patient is provided before preparation of the teeth. The prosthesis includes features that are complementary to the prepared teeth. The prosthesis can be installed immediately after preparing the teeth using the preparation guide. With the high level of accuracy and precision in the preparation of teeth, no modification of the prosthesis would be needed for installation.

The present invention provides a dental mill blank that exhibits desirable resistance against wear in opposing teeth. The present invention relates to a dental mill blank comprising: an inorganic filler containing an inorganic filler (A) and an inorganic filler (B); and a polymer, the inorganic filler (A) partly forming an aggregate, and the dental mill blank satisfying the following formulae (I) to (III),

0.001a<0.32(I)

0.3b10(II)

5x80(III),

where a is an average primary particle diameter of the inorganic filler (A) in micrometers, b is an average primary particle diameter of the inorganic filler (B) in micrometers, and x is an average particle diameter of the aggregate in micrometers.

Preferably, the dental mill blank comprises an island component containing the aggregate, and a sea component containing the inorganic filler (A) and the inorganic filler (B).
