A bone implant for at least partial insertion into a bone and/or cartilage. The bone implant is at least partially formed of a metal alloy of at least about 90 wt % of a solid solution or a rhenium and molybdenum alloy.

A dental implant has an implant body made of diamond material, the implant body being provided with a bore hole that has at least one lateral dimension and a depth dimension, the lateral dimension and the depth dimension being mm sized. The bore hole is substantially formed by laser light being directed at the implant body to form said bore hole by softening said diamond material at an intended location of said bore hole. The bore hole is further defined by utilizing at least one metallic drilling tool to remove more of the diamond material after initial formation of the bore hole by said laser light. Preferably, the drilling tool has a cone shaped drilling head or a rectangular drilling head.

The invention relates to dental field, more specifically in the field of periodontics, and describes the construction and working of a modular gum architecture device made of inert, biocompatible, bone-integrable and/or absorbable material to replace in part or totally the lost alveolar bone and restore the anatomy of the gum around the tooth or implant. The device may recreate the region of the interdental papilla or may fill in empty spaces caused by protocol-type prostheses (fixed dentures). It can also serve as support for teeth already softened or softening, for implants already installed or even for implants to be installed.

A polymerisable dental composite material comprising (i) 70 to 85% by weight of an inorganic filler component comprising at least one dental glass and optionally at least one amorphous metal oxide, (ii) 10 to 30% by weight of a mixture of at least two different urethane(meth)acrylates, (iii) 0.01 to 5% by weight of at least one di-, tri-, tetra- or multi-functional monomer not being a urethane(meth)acrylate, (iv) 0.01 to 10% by weight of at least one initiator, of an initiator system and optionally of at least one stabilizer and optionally of at least one pigment, wherein the total composition of the composite material amounts to 100% by weight, as well as a polymerized composite material having a flexural strength of greater than or equal to 200 MPa and an elastic modulus of 15 to 20 GPa for the production of indirect dentures.

A system for lip retraction and aerosol reduction, including a mouthpiece with an integrated single-lip retractor and aerosol suction head, single-lip internal retentive wings and external retentive wings configured to support and secure the mouthpiece in a mouth of a patient, and comfort retention notches formed between the internal retentive wings and external retentive wings to enhance comfort of the patient and to secure the mouthpiece in the mouth of the patient. The system includes a High-Volume Evacuator (HVE) valve stem configured for attachment to an HVE suction tube to provide suction for the aerosol reduction.

An improved dough-like filler material for use in dental and orthodontic modelling and the manufacturing methods that may be used to produce such improved dough-like filler material.

A protection device for transoral surgery includes: a main body configured to be fitted into an oral cavity of a human body and to expand a mouth vestibule between teeth and a lip of the human body; and at least one insertion device provided to the main body and having a through hole formed therethrough to enable insertion of a trocar required for a surgery. The main body includes: a tooth coupling part configured to be fitted on the teeth of the human body; an expansion part to be disposed on an outside of the tooth coupling part and configured to expand the mouth vestibule to allow the teeth and the lip to be spaced apart from each other; and an extension part configured to connect the tooth coupling part and the expansion part.

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.

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).

Orthodontic arch wires with specific shapes and bends designed to encourage expansion of the posterior teeth while preventing the flaring of anterior teeth during the alignment phase. The arch wires divide the dentition into sections and treat each section differently so as to minimize undesirable effects during the alignment process. While the arch wires of the present invention are used to improve mechanics with non-extraction, they can also be used in extraction cases to avoid round tripping and some iatrogenic side effects that can occur by engaging all the teeth at the same time. The arch wires of the present invention can be preformed or customized to each case. The arch wires of the present invention are generally of two types referred to as sectional (S-RA) wires and consolidation (C-RA) wires.
