The present application provides a glass composition comprising 10-50% by weight CaO, at least 15% and less than 50% by weight PO, less than 3% by weight AlO, less than 10% by weight LiO, NaO, and KO combined, and 0-60% by weight of SrO, MgO, BaO, ZnO, or combinations thereof; dental compositions comprising the glass composition, and methods of making and using such dental compositions.

Dental compositions with calcium phosphorus releasing glass

The present application provides dental compositions, and methods of making and using dental compositions that include a calcium and phosphorus releasing glass. Such dental compositions can be useful for delivering ions to the oral environment.

An orthodontic article and method of making the orthodontic article, where the orthodontic article includes a fine-grain ceramic bracket and a metal liner secured in an archwire slot of the bracket with a brazing alloy comprising silver, copper, and at least about 1.5% by weight titanium.

Orthodontic bracket with brazed archwire slot liner

An indirect bonding tray for orthodontic bonding procedures has moisture control structure that is located next to the patient's teeth when the tray is placed over the patient's dental arch. The moisture control structure tends to draw moisture away from the adhesive used to bond the appliances to the teeth. As a consequence, the probability that the resulting bond between the appliances and the teeth is adversely affected by the presence of moisture, blood or other fluids in the patient's mouth is decreased.
