Apparatus and method for installing a multi-tooth dental prosthesis in one session are shown and described. A first tool attaches to the jawbone, and serves as a foundation for subsequently used guides. Existing teeth and dental fixtures are removed, and the bone tissue is removed to accommodate the prosthesis. Subsequently, a drill guide is used to drill implant holes. An abutment guide is then used to place abutments. Copings are then installed. Next, the prosthesis may be installed and cemented to the copings. A resinous filler material may be applied to fill gaps and holes in and between the copings and the prosthesis, and is sanded smooth.

A bolt-type implant includes: a bolt (12) configured to be inserted into a vertical hole drilled in a mandible (including an alveolar bone) at a position in which the implant will be placed; a nut (20) configured to be fitted to the bolt inserted into the mandible and fix the bolt to the mandible (including the alveolar bone); and an abutment (11) formed on a bolt head of the bolt so as to constitute a single body with the bolt and configured to be connected to a crown (artificial tooth).

An adaptor for a dental implant abutment includes a body extending along a longitudinal axis between a proximal end and a distal end. The body has a longitudinally extending bore extending from the proximal end for sliding receipt of a post of a dental implant abutment. The body has a distal shaft for inserting into a dental prosthetic, and the distal shaft tapers in outer diameter going towards the distal end. The body has proximal flange for securing between the dental prosthetic and the dental implant abutment. The proximal flange has a first ledge for abutting the dental implant abutment and a second ledge for abutting the dental prosthetic, and the second ledge tapers in outer diameter going towards the distal end.

The present invention provides a trabecular porous tantalum dental implant and a preparation method thereof. The trabecular porous tantalum dental implant provided by the present invention has a cylindrical structure, and sequentially includes a top functional area, a middle functional area and a bottom functional area from top to bottom. The top functional area has a compact structure. The middle functional area has a porous bionic trabecular structure. The bottom functional area has a compact structure. The trabecular porous tantalum dental implant is integrally prepared through an additive manufacturing technology by using pure tantalum or medical tantalum alloy powder as a raw material. The trabecular porous tantalum dental implant provided by the present invention has a high friction force, strength and modulus close to those of human bones, an excellent bone ingrowth effect, high implantation stability and long service life.

A monolithic dental implant formed from an additive manufacturing method can include a non-porous portion and a porous structure. The porous structure can increase osseointegration of the dental implant and increase the secondary stability.

An improved fixing pin support for a dental prosthesis in order to be able to connect the dental prosthesis to a jaw by means of fixing pins which can each be moved through a guide bore in the fixing pin support. The improved fixing pin support has a guide sleeve separate from it which can be temporarily fitted over the fixing pin support so that the guide bore can be formed in the fixing pin support through a guide channel in the guide sleeve, by precise guidance of a drill. After this, the guide sleeve can be removed from the fixing pin support.

A dental prothesis subsurface assembly including an O-ball joint distal from a neck, the neck having a smaller diameter than the O-ball and extending from an implant or an abutment, and a polymeric sleeve having a first inner diameter portion and a different second inner diameter portion the second inner diameter portion or the first inner diameter portion adapted to overlie the neck and the O-ball joint and having a portion of the O-ball joint extending into the other portion, the other portion adapted to receive a socket of a prothesis to prevent direct contact between the O-ball joint and the socket. Additionally, a process of joining a prosthesis to an implant including placing a polymeric sleeve over the O-ball joint and the neck of the implant and inserting a socket of the prosthesis over the sleeve joining the prosthesis and the implant without direct contact therebetween.

Method for manufacturing a dental prosthesis on implant, characterized in that it comprises a step of manufacturing of the outer wall (E5) of the dental prosthesis and a step of manufacturing of at least one connection (E6) intended for fixing on to at least one implant.

A bolt-type implant includes: a bolt (12) configured to be inserted into a vertical hole drilled in a mandible (including an alveolar bone) at a position in which the implant will be placed; a nut (20) configured to be fitted to the bolt inserted into the mandible and fix the bolt to the mandible (including the alveolar bone); and an abutment (11) formed on a bolt head of the bolt so as to constitute a single body with the bolt and configured to be connected to a crown (artificial tooth).

A multifunctional prosthetic component developed to have multiple functions within the conventional or digital workflow, in which a temporary or permanent prosthesis is made for a dental rehabilitation unit that is cemented or screwed on a dental implant. Thus, the component has a geometry that allows it to be used as a conventional closed tray transfer, conventional open tray transfer, scanbody, and temporary abutment, basically including three main regions: a lower region, an intermediate region and an upper region, being also able to cooperate with a positioner cap.
