摘要： To detach a prosthetic part (3) which is firmly joined to a tooth stump (1) it is necessary to destroy the fixed connection between the prosthetic part (3) and the tooth stump (1) simply and without causing pain. This is achieved by carrying out the following steps: a holding member (13) is placed onto the prosthetic part (3) in such a way that a non-rotating connection is created between the holding member (13) and the prosthetic part (3); a drive motor (23, 30) connected to the holding member (13) in a driving manner is switched on; oscillations about the vertical axis (6) of the prosthetic part (3) are produced by means of the drive motor (23, 30) and one or several linking members (19, 20, 22, 27, 28, 29) positioned between the drive motor (23, 30) and the holding member (13); the oscillations are transmitted to the prosthetic part (3) by means of the holding member (13) in such a way that a cement or adhesive layer (4) between the prosthetic part (3) and the tooth stump (1) is detached by the torsional moment produced by the oscillations about the vertical axis (6) of the prosthetic part (3); and the prosthetic part (3) is removed from the tooth stump (1) after the cement or adhesive layer (4) has been destroyed.

摘要： This invention is a method and tool for fracturing the interface between dental structures that have been cemented together. The method is accomplished by positioning a rapid impacting tool (21) at about 90 degrees against the one side of the lower portion of a cap (15) covering a tooth (13). The opposite side of the cap is abutted with a kinetic energy absorbing element (27). The flexing against the cap (15) is small while the frequency is high.

摘要： A pneumatic remover assembly having a central housing (3) with a reciprocating internal mass (11) and a spring (13), a first end unit (17) having a spool-type valve (19) for activating the remover, a second end unit (29) having various conduits disposed therein for introducing and exhausting compressed air in and out of the remover, and a unique adjustment ring (35) which is capable of adjusting the flow rate of the compressed air which is introduced to the remover, thereby regulating the striking intensity of the remover. The adjustment ring (35) comprises an airflow groove (51) disposed within the interior surface of the adjustment ring which is in contact with the second end unit (29) of the remover assembly. This airflow groove (51) has a gradually increasing depth along its length and is in continuous communication with the compressed air injection conduit (32) disposed in the second end unit.

摘要： The instrument comprises a U-shaped yoke (10) for straddling the buccal and lingual surfaces of a crown (36), an operating screw (14) co-operating with the threaded bore (9) formed in the central portion (13) of the yoke. The limbs (11,12) of the U-shaped yoke are bifurcated and between each bifurcated limb, crown engaging members (18,19) are mounted on pivots (20,21). The crown engaging members are formed with frictional crown engaging surfaces (28,29) of progressively increasing radius as indicated by lines (a,b,c). In operation, a hole (35) is drilled in the centre of the crown (36). The instrument is placed in the position shown in Figure 1 and the operating screw (14) is rotated to cause the end (16) to pass through the hole (35) and engage the tooth (37). Further torque applied to the screw (14) causes the surfaces (28,29) to lock against the crown at the same time as causing the yoke to move upwards thus removing the crown from the tooth.

摘要： Described herein are systems and methods for extracting a broken fragment of a dental abutment screw from a dental implant. An exemplary system comprises an extractor tool having a tubular outer body and a conductor positioned within the tubular outer body, and an applicator that receives and end of the extractor tool and also includes a heating element that converts electrical energy into heat that is conducted to the extractor tool to melt a thermoplastic adhesive in a cavity at the distal end of the extractor tool, such that the melted thermoplastic adhesive can conform to and engage with a broken fragment of a dental abutment screw within a dental implant when the adhesive cools. The extractor tool can then be rotated to unscrew the broken fragment from the dental implant.

摘要： Oral appliance activation devices and methods which are used to facilitate the securement, adjustment, or removal of an oral appliance, e.g., a crown or bridge, from a reconfigurable abutment assembly are described. The adjustable abutment assembly may be secured to an anchoring implant bored into the bones within the mouth. The abutment assembly has a projecting abutment portion with one or more shape memory alloy elements extending along the projecting abutment portion. Energy may be applied to the elements via the activation devices directly over or adjacent to the oral appliance to actuate the elements and thereby either secure or loosen the oral appliance relative to the abutment.

摘要： There exists no dental extracting device which provides a satisfactory solution. The invention concerns a novel system which consists in incorporating in the crowns or bridges, before they are cemented in the mouth, a threading (9) in the crown (11) lingual surface and in filling said threading (9) with polymerised silicon. On the crown (11) inner occlusal surface a silicon film is applied and made to communicate with the silicon in the bore. When such a cemented crown (11) needs to be extracted, a silicon pump is fixed on the crown (B) threaded bore (9) and by actuating a screw piston silicon is injected into the cavity (10) formed by the silicon film beneath the crown thereby enabling it to be extracted effortlessly.
