摘要： A system for removing dental prosthetics and restorations effectively and efficiently without damaging the dental prosthetic or restoration and with minimal discomfort to a patient is disclosed. The system features central holder designed for receiving and securely supporting a single or plurality of support arms in a spaced apart arrangement, whereby each support arm is capable of supporting an adjustable and pivoting attachment designed to adhesively engage and remove a dental prosthetic and restoration with the application of force. The system also features a plurality of independent attachments that can be used to adhesively engage and effectively remove a dental prosthetic and restoration with the application of force.

摘要： A dental crown remover has forceps with opposing beaks. Each of the beaks has a flattened base and a notch located at the base. The faces of the notch form an angle of about 90 degrees to one another, and the lower face of the notch intersects the base at about a 50-degree angle. The notch is intersected by a longitudinal cavity having a width less than that of the beak. This structure defines two sharp points where the longitudinal cavity intersects the base of the beak and the lower face, and two stops where the longitudinal cavity intersects the upper face of the notch. When the beaks of the forceps are moved toward closure, the points of each beak are capable of penetrating and holding a crown, providing stable support at least at four points, which support allows twisting and rocking motion to be applied to break the tooth-to-cement bond holding the crown in place.
摘要翻译：牙冠去除剂具有相对的喙的钳子。每个喙具有平坦的基部和位于基部的凹口。凹口的面形成大约90度的角度，并且凹口的下表面以大约50度的角度与基部相交。该切口由宽度小于喙的宽度的纵向腔相交。这种结构定义了两个尖点，其中纵向腔与喙的底部和下表面相交，以及两个止动件，其中纵向腔与凹口的上表面相交。当镊子的喙移动到关闭时，每个喙的点能够穿透并保持冠部，至少在四个点处提供稳定的支撑，这支撑允许施加扭转和摇摆运动以将牙齿断开债券持有冠。

摘要： The invention concerns equipment for extracting root post prosthetic elements or implants, such as an instrument including two lever assembled together by a pivoting and non-intersecting articulation, each of the levers having a handle and an extracting branch extending on either side of the articulation such that when the two handles are brought closer together, the two extracting branches are spaced apart. The ends of the extracting branches of the instruments are curved so as to form an angle with the remaining part of the branches. There are U-shaped extracting end pieces designed to be removably positioned and pivotably mounted, at the curved ends of the extracting branches.

摘要： A dental implement has two moderately flexible hemostat-like handles enabling an operator to apply safely controlled force through finger and thumb grips to bring coplanar bracing and grasping beaks toward one another for gentle removal of crowns or bridges from the mouth of a patient. The bracing beak bearing on the occlusal surface of an underlying tooth is readily modifiable in length or angular position to accommodate a variety of tooth sizes, locations and orientations, and the grasping beak is hollow ground to provide enhanced purchase on a gingival margin or supramarginal notch of a crown. A method of crown or bridge removal utilizing an improved, lightweight, controlled force dental implement employs an iterative sectioning of the crown or bridge during removal.

摘要： A method and means for removing firmly affixed, binding, stuck or cemented dental restorations and appliances, which includes a substance which when held under compressive force forms strong adhesive properties between opposing surfaces sufficient to remove firmly affixed, binding, stuck or cemented dental restorations and appliances. The substance forms a strong temporary adhesive bond due to its strong adhesive properties developed under compression between the surface of the restoration or appliance to be removed and the instrumentality performing the removal, this being achieved with no tools or mechanical devices. The instrumentality, for example, comprises the jaws of the patient which are used to apply compressing force and a forceful rapid jerking reverse removal pressure to the restoration or appliance by the muscular force of the patient's jaw opening.

摘要： The invention relates to a removable dental restoration for filling an edentulous space defined at each end by a natural tooth, the restoration having at each end a means for resiliently gripping the adjacent natural tooth. In a first embodiment, the gripping means is releasable by application of opposing forces to the longitudinal side walls of the restoration. A second embodiment has the gripping means releasable by applying a simultaneous force to the end wall of each respective gripping means. A plier-type tool is provided for removing the first type of restoration, wherein the plier jaws have a rigid convex central portion surrounded by resiliently compressible locating fingers. The locating fingers permit the jaws to be located at the proper position on the restoration at which time closing of the jaws causes the convex central portions of the jaws to press against the longitudinal walls of the restoration, thereby releasing the gripping means. A tool is provided for removing the second type of restoration by applying forces to simultaneously release the gripping means at each end of the restoration.
摘要翻译：本发明涉及一种可移除的牙科修复体，用于通过天然牙齿填充在每一端限定的无牙区域，该修复体在每一端具有用于弹性地夹紧相邻天然牙齿的装置。在第一实施例中，夹持装置通过将相对的力施加到修复体的纵向侧壁而可释放。第二实施例具有通过向每个相应夹持装置的端壁施加同时的力来释放夹持装置。提供了一种用于移除第一类型的修复体的钳式工具，其中钳子夹具有由弹性可压缩的定位指状物包围的刚性的中心部分。定位手指允许钳口位于恢复器上的适当位置，此时闭合钳口使得钳口的凸形中心部分压靠在修复体的纵向壁上，从而释放夹持装置。提供了一种用于通过施加力以在恢复的每个端部同时释放夹持装置来移除第二类型的恢复装置的工具。

摘要： A pair of jaws are adjustably connected to a crossbar for being received at opposite sides of a crown to be removed. A threaded member through the crossbar applies the necessary pressure onto the underlying tooth to effect withdrawal of the crown from the tooth. A quick hardening material is inserted between the jaws and the crown, providing a conforming gripping surface.
