A stable affixation system for dental implantation includes a fixation tray having, for rapid placement, a housing defining a chamber whose inner surface is configured to house a flowable or malleable material and be placed over one or more teeth during guided dental implantation surgery. A central portion not configured to flex is situated between housing side walls. Each such side wall has an upper side portion and a lower side portion. Without the lock a squeezing force on the upper side portions flexes the lower side portions outward. The lock urges the upper side portions outward so as to flex the lower side portions inward. The lock reduces or eliminates freedom of movement of the tray. The system allows rapid removal and is sturdy enough to withstand forces including from various angles and leverage. The central portion may hold registration elements.

A stable affixation system for dental implantation includes a fixation tray having, for rapid placement, a housing defining a chamber whose inner surface is configured to house a flowable or malleable material and be placed over one or more teeth during guided dental implantation surgery. Housing side walls are joined to a cross member that has a flexion region on each side of the housing, each side wall having an upper side portion and a lower side portion. Without the lock a squeezing force on the upper side portions flexes the lower side portions outward. The lock urges the upper side portions outward so as to flex the lower side portions inward, thereby urging the material, once hardened, against the teeth. The lock reduces or eliminates freedom of movement of the tray. The system allows rapid removal and is sturdy enough to withstand forces including from various angles and leverage.

Stable affixation system for guided dental implantation

A stable affixation system for dental implantation includes a fixation tray having, for rapid placement, a housing defining a chamber whose inner surface is configured to house a flowable or malleable material (configured to harden) and be placed over one or more teeth during guided dental implantation surgery. A mechanism for urging the material against the teeth may comprise side walls having an inwardly directed extra flexible arm extension or an inwardly directed step. A lock mechanism may comprise a wedge positioned over the fixation tray to reduce or eliminate freedom of movement of the tray. For rapid removal, the system may include mechanisms (for example an element rotating inside the tray) for applying force on the tray and material and for ensuring that the material adheres more strongly to the tray than to the teeth. The system is sturdy enough to withstand forces including from various angles and leverage.

A method for implanting a tooth implant in an at least partially edentulous patient including the steps of anchoring at least one attachment element in a patient's jaw bone, removeably and replaceably mounting a carrier assembly bearing at least one fiducial marker onto the at least one attachment element in a precisely repeatable position with respect to the patient's jaw bone, employing the carrier assembly for providing registration between the at least one fiducial marker and the patient's jaw bone and implanting the tooth implant by employing a tracking system which uses the registration to guide a drilling assembly.
