Patent AT-E40042-T1: [Translated] DENTAL FILLING COMPOUND CONTAINING AN ADDED POLYVINYLBUTYRAL.
Polyvinyl butyral with a degree of acetalization of at least 75% is added to a dental cement on basis of calcium hydroxide and salicyclic esters of aliphatic alcohols. By this additive improved water resistance and increased compressive strength upon hardening are imparted to the dental cement. The obtained dental cement furthermore has strongly alkaline pH value, so that an effective protection of the pulp can be achieved and formation of a secondary dentin layer is stimulated. In the common formulation of the materials for the dental cement in form of two separate mixing components the polyvinyl butyral can be added either to the mixing component containing the salicylic acid ester or to the mixing component containing the calcium hydroxide, or also to both components.
