Title: Dental implant system and a method for its manufacture

Abstract: The invention relates to a dental implant system for attaching a prosthesis to a patient's gum. The system includes implanted screws which are lined up with substantially similarly sized support extensions. The support extensions are connected using a screw-secured bar to make a support component. The support component is fixedly secured to the implant screws through use of adjusting screws. These adjusting screws also help to align the support component and the implant screws very precisely with respect to each other. In a method of manufacture for the dental implant system, precisely fitting screws are attached to working model screws that correspond to implant screws in the patient's gum. Then telescopic collars are set on top of the precisely fitting screws and fit flush with the head of the working model screws. Next, the collars are attached to each other using a transverse bar in an area just above the gum locking the collars into position. Finally, the detachable collars and the bar are used to make a casting mold for the support component containing the bar, which penetrates the gums and is supported with flush fitting in the upper surfaces of the implant screws.
