Abstract
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.
Claims15
A method of installing a drill guide for guiding drilling of holes for implants in maxillary or mandibular bone tissue in a mouth of a patient, the method comprising:
- utilizing a fixation base to serve as a mounting jig for said drill guide, wherein the fixation base comprises a generally arcuate shape with a front surface that has a plurality of openings through which fasteners can be passed, a rear surface, and a horizontal surface;
- releasably attaching a mouthpiece to the fixation base;
- installing the fixation base to the maxillary or mandibular bone tissue of the patient by utilizing the mouthpiece that is releasably attached to the fixation base, wherein the mouthpiece is configured and dimensioned to surround the teeth of the patient and is used to assure the appropriate location to attach the fixation base to the maxillary or mandibular bone tissue of the patient;
- removing the releasably attachable mouthpiece from the fixation base once the fixation base is installed to the maxillary or mandibular bone tissue of the patient;
- and
- installing the drill guide to the installed fixation base.
An apparatus for guiding drilling holes for implants in the maxillary or mandibular jaw bone of a patient, the apparatus comprising:
- a fixation base for providing an attachment surface;
- a mouthpiece that releasably attaches to the fixation base and is configured and dimensioned to surround the teeth of the patient to assure appropriate location to attach the fixation base to the maxillary or mandibular bone tissue of the patient;
- and
- a drill guide attachable to said fixation base in a position wherein the drill guide is in vertical registry with the maxillary or mandibular jaw bone, the drill guide, and a plurality of generally vertical bores corresponding in location to and in axial registry with intended implant sites.
An apparatus for guiding drilling holes for dental implants in the maxillary or mandibular jaw bone of a patient, the apparatus comprising:
- a support bar, wherein the support bar further comprises attachment elements for releasable attachment to a non-anatomical support structure;
- a plurality of generally vertical bores corresponding in location to and in axial registry with intended implant sites;
- a plurality of bosses with one boss for each one of the vertical bores, the bosses located rearwardly of the support bar and attached to the support bar by arms such that voids exist between the bosses and the support bar, the voids enabling direct observation of patient anatomy and insertion of irrigation and evacuation apparatus;
- and
- wherein the apparatus releasably attaches to a fixation base, and
- wherein the fixation base is attached to the maxillary or mandibular bone tissue of the patient using a mouthpiece that releasably attaches to the fixation base and is configured and dimensioned to surround the teeth of the patient.
