A continuous fiber-reinforced build material for additive manufacturing (AM) of fiber-reinforced composite (FRC) structures, a machine for the preparation of the build material, and use of the build material for manufacturing of three-dimensional (3D) FRC end-product devices, such as medical devices for management of musculoskeletal and dental disorders.

A dental restoration device includes a sleeve having an exterior surface and an interior pocket that is at least partially filled with a dental cement, and a crown having an exterior surface and an interior surface that is mated to the exterior surface of the crown and bonded thereto by an adhesive disposed between the exterior surface of the sleeve and the interior surface of the crown.

An implant or endoprosthesis suitable to be implanted in human or animal tissue includes two (or more than two) parts to be joined in situ. Each one of the parts includes a joining location, the two joining locations facing each other when the device parts are positioned for being joined together, wherein one of the joining locations includes a material which is liquefiable by mechanical vibration and the other one of the joining locations includes a material which is not liquefiable by mechanical vibration and a structure (e.g. undercut cavities or protrusions) suitable for forming a positive fit connection with the liquefiable material. The joining process is effected by pressing the two device parts against each other and by applying ultrasonic vibration to one of the device parts when the two parts are positioned relative to each other such that the two joining locations are in contact with each other.

A dental prosthetic assembly includes a semi-flexible reinforcement bar and a polymer and glass outer layer chemically luted to the semi-reinforcement bar outside of the reinforcement bar. The semi-flexible reinforcement bar forms an interior of the dental prosthetic assembly and at least a portion of the polymer and glass outer layer forms teeth of the dental prosthetic assembly. A coupling system of a dental prosthetic assembly includes pins disposed in openings extending into the dental prosthetic assembly and implant abutments configured to be coupled with a mouth of a patient. The implant anchors have horizontal holes configured to receive the pins. The pins secure the dental prosthetic assembly to the implant abutments by moving into the dental prosthetic assembly through the openings and into the holes of the implant abutments.

A screw suitable for use specifically in the field of oral dental surgery consists of a bioresorbable material and comprises a drive that can be broken off by means of a predetermined breaking point and/or has a thickened shaft below the contact surface of a cap of the head of the screw.

A curable composition for a denture base is provided which comprises a paste-like composition containing (A) (meth)acrylic monomers, (B) a monomer-absorbing porous organic cross-linked polymer which can absorb the (A) (meth)acrylic monomers, and (C) a polymerization initiator selected from a photopolymerization initiator and a thermal polymerization initiator, wherein the content of (B) the monomer-absorbing porous organic cross-linked polymer is 20-80 parts by mass per 100 parts by mass of the (A) (meth)acrylic monomers, and the absorption amount: R.sub.Ab={(g−A)/(g−B)}, measured in accordance with JIS K5101-13-1:2004, and defined by the amount of (A) (meth)acrylic monomers: g−A (unit: g) absorbed per unit amount of (B) the monomer-absorbing porous organic cross-linked polymer: g−B (unit: g) is greater than or equal to 1.5.

Dental implants may be designed using a three-dimensional scan of an extracted tooth root and/or a corresponding socket site. The dental implant may include three portions: a root portion designed to sit below the patient's gum line, a connector portion positioned above the root portion and designed to sit above the gum line, and an abutment portion positioned above the connector portion upon which a temporary or permanent crown may be placed. The root portion may include three sections that correspond to three areas of a three-dimensional scan of an extracted tooth root. The first and third sections of the implant may have a size and shape that corresponds to a first and third portions of the three-dimensional scan, respectively. A circumference of the second section of the implant may be smaller than a corresponding circumference of the second section of the three-dimensional scan of the tooth root.

The invention relates to a dual fixation system for dental implant prosthesis consisting of: an intermediate abutment assembly for fixation on the implant, clip fixation device, fixation screw and cylinder that allows the prosthesis to be screwed or retained by clip as appropriate, individually or independently for each implant.

This system facilitates both the immediate loading technique and the execution of the definitive prosthesis made on an intermediate abutment, since retention by clip is very advantageous in the case of implants with unfavorable emergencies, joining them to the structure as abutments and without compromising the esthetics of the case.

A dental implant includes: a base having exterior surfaces and a plug opening formed therein; a plug assembly inserted into the plug opening; and at least one region of porous ingrowth material associated with at least one of the exterior surfaces of the base.

Implant placement assist (IPA) systems and methods for creating a dental implant chamber in an alveolar ridge of a jawbone of a patient, the alveolar ridge being atrophied and needing augmentation before a dental implant can be placed. The IPA system includes a non-osseous spacer and an anchor to maintain a position of the non-osseous spacer within a bone graft cavity of a patient. Bone graft material can be positioned around the non-osseous spacer and the anchor and maintained within the bone graft cavity during healing, where bone is regenerated within the bone graft cavity. After healing, the non-osseous spacer can be removed, thereby forming the dental implant chamber that is immediately ready to receive a dental implant.
