    摘要: The interdental wedge for the use during the insertion of approximal fillings of light curing synthetic material comprises the combination of a sole portion having disposed thereon an insert of a light conducting synthetic material and a light conducting element, such as a light reflector, to conduct the light necessary for curing and coming from the front surface of the wedge on the filling. The sole portion consists of a material which is compressible and requires strongly increasing forces for further compression; thus, the wedge can snugly fit to the approximal contour of the tooth to be treated and exert sufficiently high separation forces. Preferably, the material of the sole portion is wood whose fibers are preferably aligned in lengthwise direction of the wedge, and/or a synthetic material having included therein compressible filler particles. Thermoplastics and thermoplastic elastomers are preferred synthetic materials. Such a wedge combines the advantages of wood or a synthetic material having similar compression characteristics for a good adhesion of the wedge and sufficient separating forces, with the advantages of a wedge made of a light conducting synthetic material, in order to bring about or to accelerate the curing of the synthetic filling.

    摘要: The cup to be used as a paste carrier for dental hygienic consists of a rubber elastic material and can be driven for rotation by a hand piece. The cup comprises a paste receiving part, the inner side enlarging towards its open edge as well as the outer side of the cup enlarging towards its open edge comprising spiraled ribs which are running in the opposite direction to the rotational direction of the hand piece. The structure on the inner side of the paste receiving part allows a continuous supply of paste and a cooling of the cup, and the structure of the outer side of the cup prevents a bale formation of the mucous and guarantees an effective cooling of the cup.

    摘要: The ablator is made with synthetic resins reinforced so as to resist the mechanical stresses of flexion and abrasion. The resins are reinforced with metallic or non-metallic fibers totally incorporated in them, and are reinforced against wear due to abrasion by a modification in their surface molecular structure by means of a process of ionic implantation or similar procedures. Preferably, the synthetic resins used belong to the group of polyarylamides which exhibit better characteristics of mechanical resistance and of the duration of the sharpened edge of the ablator.
