Devices and methods of applying dental composites

InactiveUS20080213731A1Easy to spread evenlyTendency is dullTooth sawsTooth pluggers/hammersDental compositeHand held
A device and method for applying dental composite matter to dental surfaces, such as cavities in teeth, gaps in teeth, or other deformations in tooth surfaces, or other applications to teeth, or appliances and devices used with teeth, such as crowns or inlays / onlays. A hand held powered tool provides oscillation of the composite material after the composite material is grossly applied to the dental surface. The oscillation is at a frequency and amplitude that facilitates uniform spreading of the composite material over the dental surface in a desired pattern, while retarding the tendency of the material to stick to the tool.

Interproximal devices and methods of using same

ActiveUS20050271999A1Facilitates quickFacilitates easy interchangeTooth sawsGum massageEngineeringAngle of attack
A loop is formed by a bow having across one side a strip or blade. The bow has flexure and memory. The flexure and memory of the bow are imparted to the strip, enabling the strip to be either taut or loose, depending on the pressure exerted by the operator upon the bow. The bow is held and manipulated by the operator with the thumb and finger. The strip is positioned under tension. A holder for the device allows additional variability in the angle of attack of the strip, and facilitates quick and easy interchange of the strips. A holder avoids insertion of fingers far back in the mouth, where working space is limited.

Apparatus and method for removing enamel from a person's tooth

According to one embodiment, an apparatus for removing enamel from a person's tooth includes a blade portion and a handle portion. The blade portion includes an abrasive surface adapted to remove enamel from the tooth in response to reciprocating movement of the abrasive surface against the enamel of the tooth. The handle portion is coupled to the blade portion, has a substantially solid cross-section, and is adapted to be inserted into a corresponding opening in a driver mechanism that is adapted to drive reciprocating movement of the blade portion to provide the reciprocating movement of the abrasive surface.

Dental filing tool

A dental filing tool having a handle easy to hold between fingers which arches over and secures at both ends a thin filing strip coated with some superfine abrasive material, especially but not limited to diamond dust, or alternatively a sharp cutting system along the edge or lateral surface. From hole-like openings at each end, the strip is fastened between each end of the handle with sufficient tension in the strip to create a rigid filing and grinding surface. On the outside edge of each vertical arm of the handle is a smooth flatten surface where to place fingers to hold the handle. The horizontal top arm of the handle that extends above the filing strip tapers in thickness from the top down towards the filing strip reducing in thickness to a beveled edge. The vertical arms of the handle also taper in thickness inwards towards the filing strip reducing in thickness to a beveled edge.

Piezotome for maxillary sinus operation

A piezotome operation unit for lifting a maxillary sinus at a position of placement of an implant upon lifting the maxillary sinus, which forms and enlarges the vertical hole with ease in a remaining bone of the maxillary sinus though vertical approaching, and upon forming a lateral window below a malar bone through lateral approaching, prevents a maxillary membrane from becoming damaged, thereby ensuring continuous, safe lifting so that the operating time is shortened and the efficiency of the operation is maximized.

Micro-saw blade for bone-cutting surgical saws

The invention provides a surgical cutting blade for cutting bone material when the blade is coupled to a hand-held surgical saw having protrusions extending therefrom that interface with the cutting blade. The cutting blade includes a distal end comprising a plurality of cutting teeth and a shank portion adjacent the distal end. It also includes a proximal end adjacent the shank portion. The proximal end is shaped to attach to the surgical saw and includes an upper substantially planar surface and a lower substantially planar surface and a side edge extending between the upper and lower planar surfaces. The side edge at least in part defines an outer perimeter extending about the proximal end. The outer perimeter includes a plurality of indentations forming openings configured to receive and interface with the protrusions of the surgical saw in a manner that the protrusions cooperatively impart motion to drive the blade.

Interproximal dental strip

ActiveUS8439678B1Controlled and effective workingTooth sawsMechanical engineeringEngineering
An interproximal dental strip with a serrated zone flanked by abrasive zones in repeated longitudinal succession along a side face of the strip. The abrasive zones have a plurality of abrasive sections with non-abrasive sections between. The abrasive sections are inclined with respect to the side edges of the strip such that only a portion of each abrasive section makes grinding contact with a tooth at any given time for more controlled and effective working of the strip.

Dental filing tool

A dental filing tool having a handle easy to hold between fingers which arches over and secures at both ends of a thin filing strip coated with some superfine abrasive material, especially but not limited to diamond dust, or alternatively a sharp cutting system along the edge or lateral surface. From hole-like openings with slots at each end, the strip is fastened between each end of the handle with sufficient tension in the strip to create a rigid filing and grinding surface. The handle is made from formable materials not limited but like plastics injected into mold with which a filing strip is inserted. On the outside edge of each vertical arm of the handle is a smooth flatten surface where to place fingers to hold the handle. The dental filing tool is disposable when the abrasive material of the filing strip wears off.

Methods and apparatus for periodontal scaling and debridement and gum tissue ablation for treating periodontal and peri-implant disease

The present disclosure is directed to tools, systems and methods for recontouring / reshaping gum tissue by engaging a consumable tip on a powered tool to abrade / ablate excess or mal-contoured gum tissue to allow better visualization of the tooth / implant structure and reduce the periodontal pockets to provide improved access for cleaning by both the patient and clinician. In some embodiments, the powered tool may use vibrational movement, longitudinal reciprocating movement, rotational movement, reciprocating rotational movement, or a combination of any of the above movement schemes. In some embodiments, a consumable tip may be directed for cleaning tooth / implant surfaces and for recontouring / reshaping gum tissue. The powered tool itself may be constructed to allow the cooling water flow used for operation to be directed to the site where the procedure is carried out for irrigation or to be directed elsewhere at the user's selection to facilitate gum contouring procedures.
