Filed:

Apr 6, 2001

Appl. No.:

09/828593

Inventors:

Neal B. Gittleman - Houston TX 77046

International Classification:

H61C 13225

US Classification:

433172, 433214

Abstract:

An apparatus and method comprised of dental implant impression mounting hardware with a non-interfering, low profile for making time saving and accurate, simultaneous upper and lower impressions and bite registration, with the mouth completely closed and the jaw accurately positioned in centric closure. A low-profile, impression post is snapped within a matching low profile, winged and perforated impression cap held securely within a self-curing elastomeric impression material. The cured impression material retains the low profile impression cap which snaps free of the mating low profile impression alignment post. The impression post is removed and attached to an analog of the permanent endo-osseal implant and snapped back into low profile impression cap embedded in the elastomeric mold. This low profile assembly prevents interference with the taking of a simultaneous upper and lower elastomer impression of the accurately interdigitated jaw using a âtriple trayâ while insuring excellent registration.

Appl. No.:

10/210630

Inventors:

Neal B. Gittleman - Houston TX 77098

International Classification:

A61C 1100

US Classification:

433 34, 433 53, 433 60

Abstract:

An aligning dental impression transfer method and apparatus is described in which the transfer of the bite registration in centric occlusion is accurately preserved from a triple tray impression to the positioning upon an articulator. At each stage of the casting of a working model the spatial relationship of existing dental structures are preserved.

Appl. No.:

10/696351

Inventors:

Neal B. Gittleman - Houston TX, US

International Classification:

A61C009/00

US Classification:

433 38, 433 37

Abstract:

An apparatus and method to avoid dental impression material distortion comprised of dental impression triple tray with a flexible hinge rendered inflexible by a light-cured compound. The curing light is conveyed by an optical fiber assembly. Accurate simultaneous impressions of upper and lower impressions and bite registration, with the mouth completely closed and the jaw accurately positioned in centric closure are insured. Spring back of the impression tray frame caused by bite pressure against points on the frame are minimized by allowing the hinge element to initially flex when first placed in the mouth. While the impression polymer is curing, a light of the proper frequency range is delivered via the optical fiber to the light-cured compound in the hinge area to render the hinge inflexible.

Inventors:

Neal B. Gittleman - Houston TX, US

International Classification:

A61C 8/00

US Classification:

433173

Abstract:

A novel dental implant with flexible expansion ribs that lock into and compress the bone within a drilled hole in the jawbone. Upon tightening the screw used to mount the implant abutment, a set of thin medical-alloy ribs lock into the surrounding bone to provide an immediate and permanently strong support for a dental prosthesis while bone growth into the implant occurs. The expanding ribs turn an edge outward to lock into the surround bone and preventing the rotation of the implant assembly during installation and use.

Appl. No.:

Inventors:

Neal B. Gittleman - Houston TX, US

International Classification:

A61C 8/00

US Classification:

433173

Abstract:

An open topped, adjustable wing impression post cap apparatus with a low profile for taking triple tray impressions of upper and lower dentition with the jaw closed. The adjustable winged low profile impression cap has rotating wings to avoid interference with other mouth structures. By aligning a single projection against a matching surface, a low profile, winged impression cap is placed in a unique clocking position over a low profile impression post or an installed implant abutment. The open top low profile allows adjustment of the abutment and impression post retaining hardware. Rotating the wing assembly into a non-interfering, buccal-lingual position allows the complete centric closure of the jaw. Time and material saving triple tray procedures are improved and costs reduced.

Appl. No.:

Inventors:

Neal Gittleman - Houston TX, US

International Classification:

A61C008/00

US Classification:

433/173000, 433/172000

Abstract:

An apparatus for achieving a variable height trans-tissue extension (TTE) useful in matching a prosthesis to an underlying implant fixture to preserve soft tissue shape, improve hygienic care and prevent a dissimilar metal, electrolytic effect below the tissue line. The trans-tissue extension consists of a set of aligned, non-rotating spacers with a through-hole for an attachment screw. The full height is achieved by using the tallest of the spacers, while a shorter extension is formed from the use of a shorter spacer. This simplifies the needed inventory of variable height abutments by anticipating a wide variety of needs. The trans-tissue extension is adaptable to single implants, bar undercases, ball-end, snap-on prostheses and casting or brazing forms.

US Classification:

433/071000, 433/060000

Abstract:

An aligning dental impression transfer method and apparatus is described in which the transfer of the bite registration in centric occlusion is accurately preserved from a triple tray impression to the positioning upon an articulator. At each stage of the casting of a working model the spatial relationship of existing dental structures are preserved. The cast model of the upper and lower dentition a in perfect registration on the articulator. In the process of manufacturing molded and machined parts, the limitations in dimensional accuracy exceed those desired by the dental patient. The patient is aware of binding or interfering “high spots” greater than 5 microns. The modern cavity mold and resulting thermoplastic parts cannot be expected to hold these dimensions. These variations in dimensional tolerance are eliminated in this invention. The articulator is equipped with an upper and lower frame with magnetic or other clamping means to hold the pin blocks in preliminary alignment. During the casting procedure, accurate alignment projections are cast using the same stone slurry compound used to make the dental stone casts. Mounting holes in the pin block are positioned over conical recesses in the mating articulator plate and held in place by the magnetic clamps. The slurry is poured and hardens to form conical projections fixed to pin block but removable from the mating conical recesses. Now the pin blocks can be removed and accurately repositioned in the articulator frame. Each conical projection is cast-in-place in each conical recess guaranteeing accurate alignment.

US Classification:

433174000

Abstract:

A novel dental minipin implant fixture with detachable heads to accommodate either o-ring ball head retainers or a semi-permanently bonded overcase designed to replace a temporary denture. The dental practitioner can offer the economical choice of a removable acrylic denture to be replaced at a later date by a semi-permanently bonded porcelain prosthesis. Simply by changing the abutment head, the implanted minipin serves to anchor either choice of dental appliance.
