    摘要： A curved handpiece for dental root canal treatment forms an overall scheme of a dental curved handpiece, which is internally conductive, surface insulated, compact in structure, small in height and size and convenient to repair. A dental root canal length measuring function can be realized accurately, safely and stably, and a stable two-in-one function of combining root canal preparation and dental root canal length measurement is further realized. The structure is compact as a whole, and a good visual field is provided. The risk of instrument separation or preparation step generation in the operation process of doctors is reduced, and the safety improvement is greatly guaranteed. According to the scheme, it is convenient to disassemble, repair and clean, the risk of cross infection is reduced, and the use safety and convenience effects of the present invention are further improved. The curved handpiece has great market benefits.

    摘要： A hand-held surgical device, particularly for use in oral surgery, includes a rotatable tool, a head of the tool having a hollow-cylindrical design, and an active region, particularly for machining bones, being arranged at a distal edge of the head. A protection device is arranged which partially surrounds the distal edge of the tool and in some sections extends in the axial direction beyond the distal edge such that only a circular arc of the distal edge serves as the active region. The protection device may have a connecting element for detachably securing to the hand-held surgical device.

    摘要： The invention relates to a handpiece head (1) comprising a housing (2) and a closing cap (3), wherein the housing (2) is releasably connected to the closing cap (3) by means of a screw connection (4). The closing cap (3) comprises at least one recess (8) or at least one elevation (7), wherein the housing (2) correspondingly comprises at least one elevation (7) or at least one recess (8). When the closing cap (3) is screwed in, the elevation (7) on the housing (2) engages in the corresponding recess (8) on the closing cap (3) or the elevation (7) on the closing cap (3) engages in the corresponding recess (8) on the housing (2), so that an inadvertent release of the closing cap from the housing (2) as a result of vibrations of the handpiece head (1) is prevented by the engagement.

    摘要： A dental device includes a rounded flexible device configured to attach onto a head of a dental drill. The rounded flexible device has a first pair of opposing horizontal protrusions positioned at a first end of the rounded flexible device; a second pair of opposing horizontal protrusions positioned at a mid-portion of the rounded flexible device, wherein the first pair of opposing horizontal protrusions extend horizontally beyond the second pair of opposing horizontal protrusions; and a central vertical protrusion positioned at a second end of the rounded flexible device. The first pair and the second pair of opposing horizontal protrusions are configured to partially encircle the head of the dental drill, and the central vertical protrusion is configured to extend a length of a rotating drill bit of the dental drill.

    摘要： A number of osteotomes, n, form a set of osteotomes, for use during a ridge expansion osteotomy to reduce alveolar stress and to reduce likelihood of a fracture, with each osteotome of the set having a conical working tip with a free end having a diameter ϕAn, and a working base ϕBn; a first osteotome, n=1, of the set has the working tip formed with a first diameter, ϕA1=Y, at the free end, and with a second diameter, ϕB1−X, at the working base, the second diameter being larger than the first diameter, X>Y; and wherein for successive osteotomes of the set, the diameter at the free end increases as an alternate step and regressive step sequence, and the diameter at the working base alternately increases by a constant increment c, as a step function.

    摘要： A dental handpiece and a dental cleaning procedure are disclosed. The dental handpiece includes an inner barrel for rotatably retaining an ultrasonic insert, the inner barrel configured for contacting the ultrasonic insert with a cooling fluid in the inner barrel, a coil unit arranged and disposed to apply an alternating magnetic field to the ultrasonic insert when positioned in the inner barrel, an outer sheath extending around at least a portion of the coil unit, and the inner barrel is rotatable relative to at least one of the coil unit and the outer sheath. The dental cleaning procedure includes operating the dental handpiece and autoclaving the dental handpiece, allowing steam to flow through flow regions in the dental handpiece.
