Abstract: A cradle, assembly, system, and method for installing a prosthesis at a surgical site. The cradle temporarily engages the prosthesis and holds it in the correct orientation and position adjacent the surgical site. An aperture is defined in the cradle and a portion of the prosthesis is received therein. In one embodiment, the cradle, assembly and system are used to install a final dental prosthesis in a patient's mouth in a single visit to the dentist's office. A securement member pins the surgical template and subsequently the cradle to the jaw. A metal sub-structure on the final dental prosthesis is received in the aperture in the cradle. Cylinders attached to implants anchored in the jaw extend through holes in the sub-structure and are bonded to the prosthesis. The cradle is detached from the jaw and from the prosthesis prior to screws being re-inserted through the cylinders and into the implants.

Abstract: Methods and dental prosthetics for providing soft tissue adhesion to a temporary healing abutment, or other dental prosthetic (e.g., temporary or permanent). Existing prosthetics generally do not provide any significant adhesion of the soft tissue surrounding the prosthetic, to the outer surface of the prosthetic itself. Because of the presence of gaps between such structures, or simple non-adhesion even where the structures may touch (but be free and unattached relative to one another), there is a tendency for pathogenic microbes to enter into such space between the structures, and for the soft gingival tissue to recede, particularly in patients with “thin” type periodontal tissue. The present disclosure provides materials and/or surface treatment (e.g., texturing) that ensures good bonding between the prosthetic and the soft tissue, reducing risk of infection, and reducing undesirable gingival recession surrounding the prosthetic anchored on a dental implant.

Abstract: An articulated bone reconstruction bar includes a series of short segments connected by fixable axles. The length of the bar is adjusted by varying the number of segments. Before the fixable axles are tightened, the bar is positioned across a discontinuity on a bone. It is adjusted to match the contour of the bone, and the fixable axles are tightened to fixate the connections between the segments and make the bar rigid. The bar is then attached to the bone with mounting screws extending through the segments. Fixable axles with long posts may be used for mounting a dental support plate at the gum line in an area where bone has been lost or removed. If failure occurs, the fixable axles enable the broken segments to be replaced without replacing the entire bar.
