Abstract
Abstract A method for preparing dental restoration which is to be secured in the mouth of a dental patient includes providing a base plate with ready made x-ray opaque restorative teeth thereon, the base plate being formed in correspondence with the mouth of the patient in which the restorative teeth are to be fixedly secured. The base plate is temporarily situated in the patient's mouth and then the temporarily situated position of the base plate in the patient's mouth is observed, preferably via an x-ray. The temporarily situated position of the base plate in the patient's mouth is assessed to determine predetermined locations at which drill holes for facilitating the fixed securement of the restorative teeth in the patient's mouth are to bored.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
175 words
A method for preparing dental restoration which is to be secured in the mouth of a dental patient, comprising: making a base plate by taking an impression in the mouth of patient, the base plate having a generally planar top surface; adhesively securing restorative teeth onto the generally planar top surface of base plate, the undersides of the restorative teeth being planar so that misalignment when they are placed on the surface; temporarily situating the base place with the restorative teeth thereon in the patient's mouth; observing the temporarily situated position of the base plate in the patient's mouth via a selected one of an x-ray assisted observation or a non x-ray assisted observation; assessing the temporarily situated position of the base plate in the patient's mouth to determine predetermined locations at which drill holes are to be bored, the drill holes serving for facilitating the fixed securement of the restorative teeth in the patient's mouth; and boring the drill holes at the predetermined drill hole locations in the base plate and the restorative teeth.
Claim 2
Independent Claim
175 words
A method for preparing dental restoration which is to be secured in the mouth of a dental patient, comprising: making a base plate by taking an impression in the mouth of patient, the base plate having a generally planar top surface; adhesively securing restorative teeth onto the generally planar top surface of base plate, the undersides of the restorative teeth being planar so that misalignment when they are placed on the surface; temporarily situating the base place with the restorative teeth thereon in the patient's mouth; observing the temporarily situated position of the base plate in the patient's mouth via a selected one of an x-ray assisted observation or a non x-ray assisted observation; assessing the temporarily situated position of the base plate in the patient's mouth to determine predetermined locations at which drill holes are to be bored, the drill holes serving for facilitating the fixed securement of the restorative teeth in the patient's mouth; and boring the drill holes at the predetermined drill hole locations in the base plate and the restorative teeth.
Claim 3
Dependent Claim
47 words
A method according to claim 1 , wherein the temporarily situated position of the base plate in the patient's mouth is observed via an x-ray assisted observation which includes an x-ray of the temporarily situated base plate, with the restorative teeth secured thereon, in the patient's mouth.
Claim 4
Dependent Claim
49 words
A method according to claim 1 and further comprising removing the restorative teeth from the base plate after the base plate has been taken out of the patient's mouth, the drill holes in the base plate indicating drill hole locations for subsequent installation of implants in the patient's mouth.
Claim 5
Dependent Claim
41 words
A method according to claim 1 and further comprising preparing dental restoration based upon the restorative teeth and securing the dental restoration to an implant in the patient's mouth via a selected one of an abutment and a non-abutment anchoring means.
Claim 6
Dependent Claim
16 words
A method according to claim 1 , wherein the restorative teeth comprise an x-ray opaque material.
