摘要： Dental cement compositions (including two-part compositions), kits, and related methods are used for bonding a dental prosthetic appliance to a tooth. A first part includes an amine activator component and a zinc oxide reactive filler, while a second part includes a polymerization initiator (e.g., benzoyl peroxide) and a polymerizable component having a structure including at least one acrylate or methacrylate group at one end and a carboxylic acid group at another end. A temporary cement composition advantageously exhibits reduced compressive and/or bonding strength relative to permanent cement compositions, which provides sufficient strength to facilitate normal use of the teeth while the provisional appliance is in use, while also facilitating easy removal of the provisional appliance for replacement with a permanent appliance at a later time.

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： 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.
