摘要： Apparatus and method for injecting a fluid through perforated gingiva (24), through perforated cortical bone (28) covered by gingiva (24), and into cancellous bone (30). The method utilizes a bone bit (10) and a sealing injector (40). Bit (10) consists of a perforator (12) for forming a small diameter conduit (26) through cortical bone (28), and a larger diameter countersink (14) for forming a gingival access (22), and for forming a bony access seat (32). Injector (40) forms a seal with gingiva (24) about gingival access (22), or with the proximal bone (32). The seal is formed so that injector (40) remains in fluid communication with conduit (26). Once the seal is formed, injector (40) sealingly injects fluid into conduit (26) and into cancellous bone (30).

摘要： A convenient dental tray spacer for use in forming a thin reservoir space between teeth and a dental tray, during tray fabrication. Shim (10) segments are connected by small links (12) to form a spacer (16). The lengths of the links are readily variable. Retention to the teeth is provided by adhesive on rear adhesive surfaces (22). Alternatively, an elastic loop (24) can retain a spacer (16′). Spacer (16), or spacer (16′), remain on the teeth while the dental tray is formed, and then is pulled free from inside the formed dental trays.

摘要： The dental dam support (10) and donut (16) are comprised of a moldable, hardenable material for use as a support means for a dental clamp (14), which can prevent clamp (14) from contacting the teeth or gingiva, during anchorage of a dental dam (18). The material achieves sufficient hardness to support clamp (14) over gingiva alone, if the tooth structure is insufficient, enhances the stability of clamp (14) on the tooth or gingiva, and inhibits fluid movement past clamp (14). Softened support (10) or donut (16) material is molded over the teeth or gingiva to be clamped, clamp (14) is partly seated into the material and restrained while the material is hardened. Clamp (14) is released such that it engages the support material. Another use of support (10) is to anchor dam (18) without clamp (14). Softened support (10) is molded over teeth where anchorage is desired. Support (10) is hardened and removed from the teeth. Dam (18) is placed over the teeth, and support (10) is replaced over dam (18), thereby anchoring dam (18) to the teeth. Another use of donut (16) is to isolate an area of a tooth. Softened donut (16) is molded to cover a perimeter area about an exposed work area on the teeth, and hardened.
摘要翻译：牙龈支撑件（10）和环形圈（16）由可模制的可硬化材料组成，用作牙科夹具（14）的支撑装置，其可以在锚固期间防止夹子（14）接触牙齿或牙龈（18）。如果牙齿结构不足，则该材料获得足够的硬度以支撑单独的牙龈上的夹具（14），增强了夹钳（14）在牙齿或牙龈上的稳定性，并且阻止流体通过夹具（14）运动。软化的支撑件（10）或环形（16）材料被模制在齿或牙齿上以被夹紧，夹具（14）部分地位于材料中并且在材料硬化时被约束。夹紧器（14）被释放，使得其与支撑材料接合。支撑件（10）的另一用途是不用夹具（14）固定坝（18）。在需要锚固的牙齿上模制软化的支撑件（10）。支撑件（10）被硬化并从牙齿上移除。将水坝（18）放置在齿上，并且在坝（18）上更换支架（10），从而将坝（18）固定在牙齿上。甜甜圈（16）的另一个用途是分离牙齿的一个区域。软化的甜甜圈（16）被模制以覆盖围绕牙齿上暴露的工作区域的周边区域并且硬化。

摘要： An automatic fluid injector (10, 66, or 76) having a coolant-absorbent pad (24) for pressing onto a tissue site for desensitization. When the injector (10, 66, 76) is pressed further toward the tissue site, the contained fluid is pressurized, and an enclosed needle (16) moves distally to penetrate a distal wall of injector (10, 66, 76). While needle (16) is being repositioned distally, the pressurized fluid is blocked from flowing into needle (16). The fluid blockage prevents the fluid from inadvertently warming the cold, desensitizing pad (24) and causing the patient to experience pain during needle (16) penetration. When needle (16) penetrates to a preset depth, and is sealed in the tissues, then the pressurized fluid is unblocked, and flows automatically through needle (16). In another embodiment, an instrument (46) having a coolant-absorbent felt (52) is able to unobstructably desensitize tissues prior to penetration with sharps.
摘要翻译：一种自动流体注射器（10,66或76），其具有用于压在组织部位上用于脱敏的冷却剂吸收垫（24）。当注射器（10,66,76）被进一步压向组织部位时，所容纳的流体被加压，并且封闭的针头（16）向远侧移动以穿透注射器（10,66,76）的远侧壁。当针（16）正在远端重新定位时，加压流体被阻止流入针（16）。流体堵塞防止流体无意中加热冷的脱敏垫（24），并导致患者在针（16）穿透期间经历疼痛。当针（16）穿透到预设深度并被密封在组织中时，加压流体被解除阻塞，并且自动地通过针（16）流动。在另一个实施例中，具有冷却剂吸收性毛毡（52）的器械（46）能够在用尖锐物穿透之前使组织不敏感地脱敏。

摘要： The present invention is a sheet comprised of PTFE material manufactured to specifications, and processes therefore. Use of the sheet improves a number of dental procedures where interposed between contacting dental surfaces because the sheet readily deforms under pressure. As such, it does not substantially interfere with the occlusion of the teeth, or seating of dental restorations or appliances. Novel uses for the sheet include: interference marking, molding composites, occlusal registration, dual arch impression tray membrane, and spacing phase one impressions.

摘要： Processes wherein a soft polymer sheet deforms readily under the pressure of dental surfaces brought into contact with one another. As such, the sheet does not itself interfere with such contact. Processes for the sheet include deforming the sheet between contacting dental surfaces, and noting the location and intensity of contact deformations. The position of the sheet is stabilized on the surfaces by temporary adhesion, wherein the adhered sheet does not interfere with contact. Further processes involve deforming the sheet between contacting dental surfaces such that the sheet does not interfere with the contact of the dental surfaces, and utilizing the sheet to support dental materials, such as supporting restorative composite, impression materials, and so on. The sheet is preferably comprised of polytetrafluoroethylene.
