Abstract: Provided is a dental handpiece which can prevent degradation in visibility of a surgical field. The anti-reflection layer 100 is formed on the top surface and the side surface of the head portion 241 of the lid member 24 close to the root canal of the tooth, to which the operator pays attention, and further on the outer surface of the second cylindrical member 12 (refer to FIG. 3). Therefore, the reflection of light of a dental lighting tool provided with the anti-reflection layer 100 is suppressed, and degradation in visibility of a surgical field can be avoided. In addition, visibility of stains such as proteins adhering to the lid member 24 and the second cylindrical member 12 is improved, and cleaning thereof is facilitated.

Abstract: The present invention relates to a dental drill (10) formed of titanium or a titanium alloy having a hardness greater than pure titanium, said drill extending along a central axis (A) from a proximal end (14) to a distal end (16). The drill comprises a shank (12) arranged in a proximal end region of the drill (10) and extending along the central axis (A), a flute portion (20) arranged distally to and running coaxially with the shank (12), said flute portion (20) comprising two or more flutes (22a, 22b, 22c) extending along the flute portion (20) and being interposed by lands (24a, 24b, 24c), the flute portion further comprising a central solid web and a drill tip (26) directly adjoining the distal end (28) of the flute portion (20) and comprising two or more flanks (25a, 25b, 25c) which taper radially inwardly from the distal end of each land in the distal direction toward the central axis (A), each flank (25a, 25b, 25c) comprising a cutting edge (30a, 30b, 30c). According to the invention, at the distal end of the drill point (26) at least one groove (32, 33a, 33c) is formed in the web such that the distal most end (36a, 36b, 37b, 37c) of at least one of the flanks (25a, 25b, 25c) is located radially remote from the central axis (A).

Abstract: The invention provides a dental implant system with a surface gradient microporous structure and a preparation method thereof. The dental implant system includes a non-threaded micro-cone cylindrical dental implant and an abutment, wherein the dental implant includes a microporous layer with a bionic bone trabecular structure and a base with extremely high density and mechanical strength. The dental implant system of the invention has both the precision of the internal structure and the bionic characteristics of the surface structure, which effectively improves the long-term stability after implantation, reduces the complexity of the processing process of the dental implant system, and can realize personalized and batch production.

Abstract: A system for repositioning teeth a patient from an initial tooth arrangement to a final tooth arrangement includes a plurality of incremental position adjustment appliances, each having an arrangement of cavities shaped to receive and reposition teeth of the patient. The cavities in at least one appliance in the system have a different geometry than that of at least one other appliance in the system. At least some of the appliances in the system are successively worn by the patient to exert force on at least one tooth and move the teeth of the patient from a first arrangement to a successive arrangement different from the first arrangement. The system includes a first multilayer shell with a bending stiffness factor less than about 0.1 GPa*mm3 and an elastic modulus no greater than about 1.5 GPa; and a second shell with a bending stiffness factor greater than 0.1 GPa*mm3.

Abstract: A dental component gripping device may have an exterior surface with a proximal end, a distal end, and an intermediate region between the proximal end and the distal end, and a bore with a distal portion within the distal end, a proximal portion within the proximal end, and an intermediate portion between the distal portion and the proximal portion. The distal portion may be sized to receive and grip an exterior, proximal surface of at least one dental component such as an abutment, a transfer, and a healing collar. The intermediate portion may have a reduced-diameter zone in which the bore has a diameter smaller than in an entirety of the distal portion. The reduced diameter portion may help to retain a fastener within the distal portion of the bore. The dental component gripping device may be formed of a resilient material such as a Silicon-based material.

Abstract: An interdental cleaning instrument is equipped with a base part and a cleaning part. The base part has a shaft part and a grip part. At least the shape of the base part is set in a manner such that a first pressing force required to press a portion spaced 2.5 mm apart from a tip of the cleaning part in 10 mm is 0.3 N or more and 1.4 N or less in a state in which a portion spaced 10 mm apart from the tip of the cleaning part is fixed, and a second pressing force required to press a portion spaced 8.0 mm apart from the tip of the cleaning part in 10 mm is 0.5 N or more and 2.5 N or less in a state in which a portion spaced 35 mm apart from the tip of the cleaning part is fixed.
