Benefits of technology

[0010] The present method has numerous advantages over prior methods. First, a tooth-shaped temporary prosthesis is connected to implant immediately after the implant is implanted into the jawbone of the patient. As such, the patient does not have an unsightly gap or otherwise unaesthetic appearance at the implantation site. Further, a second, separate surgical procedure is not required since the implant, abutment, and temporary prosthesis are all placed during the first surgical procedure. Further yet, since the prosthesis is left out of occlusion, it is not exposed to immediate loads. Thus, movement and disturbance of the implant is minimized during the integration period. Further yet, the implant and abutment are made from two separate pieces, and the implant is not required to have a special external thread design to help improve resistance of the implant to chewing and compressive forces.
[0012] This near net tooth shape of the crown will reduce the amount of work, time, and expense required to create a final dental prosthetic restoration. Further, the ceramic used to fabricate this crown is compatible with commercially available porcelains so that the gradients of shade and translucence of the natural tooth can be replicated. Also, the crown may be manufactured to have a size that is slightly smaller than the average natural tooth. This difference in size enables the crown to receive an additional layer of porcelain and then match the exact size of the natural tooth.
[0013] As another advantage, the prosthetic teeth of the present invention may be manufactured and sold as a kit. Each kit would include a plurality of prosthetic teeth having different sizes and shapes emulating different sizes and shapes of natural human teeth. A clinician could chose a prosthetic tooth to best match particular needs of a patient.

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.
