摘要： A metal free dental filling system is provided which prevents the transmission of destructive forces from the shrinking filling material to the sealed dental hard tissue. The system prevents the transmission of destructive forces by making the bond of the cured adhesive sealant to the dental hard tissue, i.e., the enamel, dentin, and root cement, substantially stronger than the bond of the cured adhesive sealant to the filling material. An intermediate layer material may be arranged between the dental filling material and the cured adhesive sealant. If an intermediate layer is used, the bond between the dental hard tissue and the cured adhesive sealant is much stronger than the bond between the cured adhesive sealant and the intermediate layer in order to ensure that substantially no destructive forces are transmitted from the shrinking filing material to the cured adhesive material on the dental hard tissue. The intermediate layer may be removed prior to application of the filling material.

摘要： A dental handpiece comprises an outer sleeve (1), a tool-holding socket (2) for holding a treatment tool (3) arranged in the handpiece, wherein the tool-holding socket (2) has a central axis about which the tool-holding socket (2) can be rotated and/or oscillated and wherein the tool-holding socket (2) is arranged to be driven by a driveshaft of the handpiece driven by a motor (10) housed in the outer sleeve (1). At least one Peltier element (5) is received in the handpiece in thermal contact with the tool-holding socket (2), the Peltier element (5) having a cool face in thermal contact with the tool-holding socket (2) to cool a treatment tool (3) held therein when the tool (3) is driven in rotation or oscillation.
