摘要:
A tooth loosening device comprises a body having a tooth contacting portion connected to a handling portion. The tooth contacting portion has a tooth contacting member including one or more surfaces adapted to contact a tooth, and the handling portion includes a manipulation member. The tooth contacting portion can be inserted into a mouth having a tooth in need of loosening, and the manipulation member can position the tooth contacting member so that the one or more surfaces contacts the tooth in need of loosening. The tooth in need of loosening can then be loosened by manipulation of the tooth loosening device. A vibrating mechanism can also be provided to apply vibration to the tooth in need of loosening.

摘要:
A handling device for a dental tool having a) a body having an elongated shape configured to receive a prying load from an operator; and b) one or more receptacles through the body configured to retain at least a portion of a dental tool and allow an engagement portion of the dental tool to project therefrom substantially perpendicular to a longitudinal axis of the body; wherein the engagement portion is adapted to contact a portion of a dental covering along only one of a facial side or a lingual side of the dental covering and by being wedged between a gum-line and the dental covering; and wherein the one or more receptacles are configured to transfer the prying load from the body to the engagement portion of the dental tool.

A frictionally-retained detachable dental attachment assembly or anchor device is designed to attach a dental appliance with a tooth root or implant. The assembly includes a denture attachment housing for securing in the dental appliance, an abutment attached with a tooth root or implant, and a compressible retention member with a first end in fixed attachment with the cap and a second end in snap engagement with the abutment via a frictionally-retained ball secured within a cavity of the abutment. The retention member is formed using a compressible material to allow the ball to compress and the retention member to flex while inserting the ball into the cavity. Additional friction-retained and fixed attachment configurations of the dental anchor device are provided, along with methods of securing a dental appliance in a subject's mouth by means of the friction-retained and fixed attachment dental anchor devices.
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 appliance removal tool is provided with one or more booster tubes each having a pressure-actuated expandable distal portion or cushion which, when inserted between a gum line and an implant-supported denture and connected to a supply of pressured fluid, expands radially to increase the circumference of the cushion and apply pressure to the gum line and denture to loosen or release the denture from an implant or the like. The tool may have an actuation mechanism such as a lever arm which applies pressure to a fluid chamber in communication with the booster tube, causing the cushion to expand, or a manually operated fluid pump or other pressurized fluid supply may be connected to the booster tube or multiple booster tubes to expand the cushion or cushions.
摘要:
A device for inserting a threaded dental implant (I) in a patients jawbone as well as for loosening and removing a threaded dental implant (I) mounted and possibly osseointegrated in the alveolus jaw-bone of a patient. An ultrasonic vibration actuator, e.g. a piezoelectric transducer, generates ultrasonic vibrations with a frequency within the range 20-50 kHz, preferably within 24-36 kHz, and preferably in a direction around the longitudinal axis of the dental implant (I). The actuator, being a handpiece (H) structurally connected with a handpiece head (HD). A fitting-means (F), e.g. a socket, is positioned in the head (HD) of the handpiece (H), the head (HD) being arranged for entering the patient's mouth. The fitting-means (F) is shaped to provide a rigid engagement directly with the dental implant (II, I2) or indirectly by an adaptor (AD1, AD2) being rigidly tightened on top of the dental implant (II, I2) platform. The fitting-means (F) thus transmits ultrasonic vibrations to the dental implant (II, I2) for either inserting a dental implant or alternatively loosening the dental implant from the jaw bone.
摘要:
A device for removing a loose tooth, the device including a handle, a base structure, and a retention strap, wherein the retention strap is secured about an outer surface of the loose tooth such that the base structure forms an interface with the tooth. The device further including features for increasing friction between the base structure and the tooth to prevent slippage while removing the tooth with the device.

Two-part resin-reinforced cement 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 post removal device having a hollow tubular structure having a sidewall and distal and proximal open ends, an engaging feature positioned on insides of the sidewalls, and a fulcrum positioned on the hollow tubular structure adapted for pulling the hollow tubular structure and a dental post captured therein. The engaging features can be a series of openings formed through the sidewall of the hollow tubular structure, and/or the inner wall surfaces of the sidewall that is one of at least scored, textured, dimpled, coated with a high adhesion material or other type of surface preparation chemical, and/or internally threaded. The tubular structure is of generally constant outside diameter. The inner walls can either be of constant inner diameter, or can have an inner diameter that narrows from the distal end to the proximal end either continuously, or in discrete steps of increasingly smaller diameter.
