Benefits of technology

"The present invention is a method for placing a temporary dental implant prosthesis after a dental implant is implanted into a patient's jawbone. The prosthesis is non-occlusive and non-functional, meaning it does not transmit loads or compressive forces to the implant during normal mastication. This method has advantages over previous methods as it does not require a separate abutment and reduces the time and expense required to create a final dental prosthetic restoration. The prosthesis is formed from an internal metallic core and an external ceramic crown that matches the shape of a natural human tooth, reducing the amount of work required. The prosthetic teeth can be manufactured and sold as a kit, with different sizes and shapes emulating natural human teeth."

Problems solved by technology

The patient may have an unsightly gap or otherwise unaesthetic appearance at this location.
The cap and cuff are often visibly exposed in the mouth of the patient and present an unnatural appearance.
Multiple surgical procedures are costly and not desirable for the patient.
The prosthesis, however, is left in occlusion and thus exposed to immediate loads.
This procedure has disadvantages too.
If the prosthesis and attached implant experience loading too soon, then the position of the implant may rotate, loosen, or otherwise move.
Such movement could adversely effect the integration and alignment of the implant.
One disadvantage to this system is that the implant has an elongated implant and neck portions formed from a single piece.
Further, the neck portion could not easily accommodate a screw-retained prosthesis, especially if the neck needed extensive modification.
Further yet, the implant is loaded immediately after it is placed; and such loads, as discussed above, may move the implant or otherwise interfere with its orientation or integration.
This specialized thread pattern may add additional cost to the implant.

case i

[0039] Case I

[0040] A 74-year old female had a fractured, non-salvageable first premolar. The tooth was gently elevated, keeping the soft tissue and hard tissue contours intact. There was no elevation of the soft tissue. The socket site was checked to make sure the buccal plate was intact. Direct visualization and palpation were used to identify the inter-septal buccal plate rim. In this case, the site was prepared via harvest instrumentation. The platform of the implant was set approximately 1-1.5 mm below the level on the inter-septal bone; such placement ensured the shoulder of a 2 mm abutment to be approximately 1 mm below the level of gingival cuff rim. This placement also ensured that the soft tissue would be supported to maintain its position and would allow for maximum emergence of the temporary prosthesis (or provisional). The temporary prosthesis was seated with temporary cement and taken out of occlusion. It was then allowed to heal for 16 weeks. After the healing period,...

case ii

[0041] Case II

[0042] A 47-year old man had tooth #9 that was super-erupted and mobile. Due to his present occupation, aesthetics and a quick remedy were necessary. The tooth was atraumatically removed and the socket site debrided. The position and loss of the gingiva in relation to the adjacent teeth was important here. The implantation site was prepared in a sequential fashion, utilizing drills and hand instrumentation. The implant was then seated in place, positioning the platform approximately 1-1.5 mm below the level of crestal bone. Here, the width of the socket determined the diameter of the implant, and care was taken not to perforate the buccal plate. The abutment was seated to place, the shoulder being approximately 1 mm below the crest of the gingival collar. The temporary prosthesis was placed and positioned to be out of centric occlusion and excursive movement. The tissue and implant was allowed to heal. After the normal healing time had transpired, the implant was resto...

Description

CROSS-REFERENCE TO RELATED APPLICATION [0001] This is a divisional application of prior U.S. patent application Ser. No. 10 / 861,324, filed Jun. 4, 2004, which is a continuation of U.S. patent application Ser. No. 10 / 050,028, filed Oct. 22, 2001, which issued into U.S. Pat. No. 6,746,244, and which is a continuation-in-part of U.S. patent application Ser. No. 09 / 755,240, filed Jan. 5, 2001, which issued into U.S. Pat. No. 6,368,108, all of which are hereby incorporated herein by reference in their entirety.FIELD OF THE INVENTION [0002] The present invention relates generally to a method for immediately placing a non-occlusive and non-functional temporary dental implant prosthesis in the jawbone of a human patient wherein the prosthesis has a size and shape of a natural human tooth. BACKGROUND OF THE INVENTION [0003] Numerous surgical techniques and methods currently exist to install a dental implant and prosthesis into the jawbone of a human patient. During a conventional surgical pr...
