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.
