    摘要： A dispensing syringe for dispensing a multi-component dental composition, preferably a two component composition, is provided. The syringe includes a syringe body with multiple elongated barrels for storing the components of the composition; a threaded plunger rod assembly; and a rotatable, threaded connector knob. Preferably, the syringe body has a double-barrel structure and the plunger rod assembly includes two plunger rods that slide within the barrels. The threaded knob has a through-bore with a continuous internal thread for engaging the outer threads of the first and second plunger rods. A dental practitioner manually rotates the knob to displace the first and second plunger rods and discharge the components. The dispensing syringe may further include a dispensing tip containing a static mixing element for mixing the components and dispensing the mixed composition.

    摘要： The invention provides a method of forming dental restorations, particularly dental crowns. The method involves applying a flexible cement composition to a prepared tooth surface. The composition is polymerized so that it substantially hardens. A composite crown-forming material is dispensed into a substantially transparent plastic matrix. The matrix is placed in the mouth of the patient so that the composite material is molded over the tooth surface. Then, the material is irradiated with curing light, through the matrix, so that it hardens to form a dental crown. The crown has good mechanical strength and is resistant to fracturing and breaking.

    摘要： A tri-spade dental drill with an enhanced cutting tip for preparing surgical sites for endosseous implants is described. The cutting tip incorporates a split point cutting surface for each of the three blades wherein the split point includes a positive rake angle. All three split points converge at the center of the drill, eliminating any chisel edges. The positive rake angle split point and its offset secondary cutting flutes breaks the removed bone into smaller chips, decreasing the principle cutting force necessary for drilling and facilitating material ejection.

    摘要翻译： 描述了一种具有增强切削尖端的三铲牙钻，用于为内骨植入物准备手术部位。 切割尖端包含用于三个叶片中的每一个的分割切割表面，其中分割点包括正的前角。 所有三个分裂点在钻头的中心会聚，消除任何凿子边缘。 正前角分割点及其偏移的二次切割槽将去除的骨头分解成更小的切屑，从而降低钻孔所需的主要切削力并促进材料喷射。
