摘要： A dental handpiece (10) of the type having a body (11), a head (13) and a neck (12), is improved by having at least one portion of the handpiece (10) formed by metal injection molding or MIM. The use of MIM allows for improved fabrication and function. According to one aspect of the invention, the head (13) and neck (12) of the handpiece (10) are MIM-formed as a single or unitary piece.

摘要： A dental syringe (10) has a needle (11) affixed to a carpule holder (12), which carpule holder (12) is affixed to a power drive unit (13). A harpoon (20) is provided to affix the drive unit to the carpule plunger (32). The harpoon (20) is made of stainless steel or other hard, corrosion resistant, sterilizable, material. Harpoon (20) has a unique barb geometry and hardened, knife-like edges (21). The syringe (10) may operate to divide the delivery of anesthesia into two phases. According to the method, during the first about 10 seconds of the injection, anesthetic is delivered at an extremely slow rate to maximize patient comfort. The injection rate then automatically increases to the preprogrammed rate associated with the injection type selected.

摘要： A photopolymerizable material is exposed to light to effect curing. A portion of the material is exposed to light in a conventional manner, while at least one other portion of the material is masked from direct exposure to the light by use of a mask (10) having at least one mask segment (11) which either completely or at least partially blocks the light. In this manner, the polymerization stress associated with the cured materials is limited or minimized due to extended molecular relaxation promoted by this controlled or hybrid curing technique. Also according to the invention, different segments (30, 31) of a material to be cured (22) are exposed to different wavelengths of light energy (21) or one such segment (30, 31) is exposed to light energy while another such segment is not.

摘要： In a method of restoring a tooth, the present invention provides a technique for the removal of cement after bonding a dental construct to a tooth. The effect of 5 cement removal techniques were determined by means of an in vitro study, using extracted human teeth. The best results in terms of leakage scores and interface contour were obtained by the technique disclosed, comprising the following steps: after placement of the construct on the tooth, removing excess cement with a soft, pointed brush, brushing the dental margins with a photocurable dental resin cement which is the same as or different from the dental cement used to bond the construct to the tooth; and, light curing the photocurable dental resin cement. When using resin or resin ionomer dental cements, the technique of cement removal disclosed yields improved marginal adaptation of the cement and a good marginal seal.
摘要翻译： 有几种技术被推荐用于在铸造，单板和所有陶瓷单元粘结后去除水泥。 随着树脂和树脂离聚物水泥的引入及其固化后的固有硬度，去除多余的水泥变得更加困难。 通过体外研究确定用树脂基水泥胶结的间接制备的修复体的边缘完整性和密封是否受到水泥移除技术的影响。 材料与方法 倒角准备在提取的人牙齿上进行。 将制备物的印象倒入模具中，并使用常规的实验室技术制造和铸造黄色的蜡图案。 使用树脂水泥进行胶结，采用5种技术（每种技术采用3种铸件）去除多余的水泥。 固化后，将样品浸入亚甲基蓝染料溶液中24小时并切片。 用光学显微镜测定染料泄漏评分，并用场发射扫描电子显微镜进一步检查切片。 结果：用尖锐的头发刷除去多余的水泥，并且用刷子浸入牙质粘合剂（刷到轮廓）中的边缘完成的组不仅显示出最低的泄漏评分，而且还具有 在母亲界面最有利的水泥轮廓。 临床意义：使用树脂基元素时，水泥去除技术对边缘界面的水泥适应质量有影响。

摘要： The invention provides a dental device comprising thermoplastic polyamide having a Charpy notched impact strength of at least 3.5 ft-lb/in2. Preferably the polyamide comprises at least 10 percent by weight of micro-crystals having a largest dimension less than 750 nanometers. Preferably the device is a Denture base, denture, partial denture, clasp, splint, or night guard. Preferably the polyamide has an opacity of less than 30 percent. The invention provides a metal cartridge container containing particles of thermoplastic polyamide effectively free of pigment. The metal cartridge is used in a method of making a partial dental prosthesis having a substantially transparent clasp. First a substantially transparent thermoplastic is injected into a first portion of a mold cavity of a mold containing an artificial tooth, and then a substantially opaque thermoplastic injecting into a second portion of the mold cavity. The removable partial dental prosthesis formed includes an artificial tooth supported by a base integrally connected to a clasp, wherein the base includes pigment and is substantially opaque, and the clasp is substantially transparent and effectively without pigment.

摘要： The synthesis of self-adhesive polymerizabe monomers and their application as a water containing and a water free self-adhesive dental/medical composite is described. The dental/medical composite comprises a self-adhesive polymerizable monomer, a polymerizable monomer, an acid-reactive and/or reactive and/or non-reactive filler, a diluent, a polymerization initiator and a stabilizer. As polymerization initiators are used the commonly known thermal initiators, redox initiators and/or photo initiators. The new adhesive dental composite develops adhesion to dentine of about 4 MPa. Fillers of high X-ray absorbance provide radio-opacity values graeter than that of the same thickness of aluminium.
