摘要： Condensing instruments are used for packing and condensing in connection with placement of dental composite resin restorative materials. These instruments are manufactured in metal or plastic material. Some composite resins however, contain hard particles and require a relatively large condensing pressure which causes abrasion of superficial fragments of prior art metal instruments. These fragments are confined in the restorative material and causes discolouration, often after oxidation. Plastic instruments quickly loose their surface finish, which may render it impossible to perform an adequate condensation. In order to provide an instrument which does not cause discolouration and which guarantees a durable function, at least one functional member (4 and/or 5) of the instrument consists of a metal alloy having a coating (6 and/or 7) of ceramic material which provides the working surface (8 and'or 9) of the functional member.
