A system including a method and associated structures creates efficiencies in the manufacture of prosthetic tooth support frameworks. Pre-manufactured teeth with matching internal keys are used in the setup of a patient prototype. Each key includes a shaft, a cervical platform, a retention knob and preferably at least one channel for the expulsion of excess adhesive fluid. The cervical platforms are shaped to provide intimate contact with a base of their respective tooth. The same tooth/key pairs are then used to make a framework pattern from the setup positioning. The pattern can be cast or scanned for direct machining to produce the finished framework.

Dental abutments comprising machined apical portions and additively formed coronal portions and related methods are described herein. The abutment has a machined apical portion and additive manufactured coronal portion for supporting a dental prosthesis. The apical portion has a main body having a top surface, an opposed bottom surface, and a screw-machined implant interface extending from the bottom surface that can be matingly engageable with a corresponding interface receptacle disposed in a dental implant. The coronal portion is additively formed from a second material on the top surface of the main body of the apical portion.

A dental prosthetic assembly includes an additively manufactured 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.

An improved denture system is disclosed. An improved denture system has a support bar and a denture material blank. The denture material blank has an oversize cutout to secure the support bar. The support bar has oversized implant interfaces and optional oversized tooth abutments. After securing the support bar in the denture material blank the final shape and dimensions of the implant interfaces and optionally the final shape and dimensions of the tooth abutments will be machined. The denture system will result in an accurate reference and registration between the denture teeth and base and the implant interfaces.

A bone foundation guide system has a bone foundation guide including a body that is contoured to reversibly affix to a bone segment of a dental implant surgical site, the body being further contoured accept and to guide the cutting of a portion of the bone segment from a dental implant surgical site and as well as to alternatively support a dental implant surgical guide; the dental implant surgical guide; and a bone foundation guide prosthesis as an alternative to the dental implant surgical guide. The bone foundation guide prosthesis combines with the body to accommodate the bone segment portion as placed through the body prior to the bone segment portion being removed from the dental implant site through the use of the body.
