Abstract: A method of making a surgical template used for a computer-guided dental implant surgery includes the steps of: establishing implant planning data of a patient's jaw, producing a digital plaster model of the patient's jaw, allowing the digital plaster model to have the implant planning data, integrating the digital plaster model with the implant planning data to obtain a digital machining data, holding and machining a modeling block at a machining position according to the digital machining data to form a solid jaw model corresponding to the patient's jaw and having teeth, gums, and at least one implant-position indicating structure, mounting a positioning member at the implant-position indicating structure, and producing a negative template body from an assembly of the solid jaw model and the positioning member with a thermoplastic dental material by a molding process or a vacuum forming process.

Abstract: An abutment assembly for use with a dental implant unit includes a metal pedestal unit which has a fitting bushing adapted to fittingly engage a tubular fitted wall of an implant member, a ceramic abutment body which has an annular cut-out in a bottom wall thereof to be mounted on the pedestal unit, and a tubular packing member which has a bearing ledge on an inner peripheral surface to be pressed by a bolt member when the bolt member is threadedly engaged with the implant member, and a pressing region on an outer peripheral surface to be brought to intimately abut against a pressed region of an inner tubular wall surface of the abutment wall so as to place the abutment body in a tightened position.

Abstract: A method for designing an abutment tooth which mainly comprises the steps of: setting a reference abutment device with a feature on an analog of a mouth model; positioning a digital abutment with the same configuration as the reference abutment device on the analog to obtain the configuration data of the positioning of the digital abutment on the analog; optimally adjusting the digital abutment by using as a reference the configuration digital data without affecting the configuration of the digital abutment and the analog, thus finishing the design of the abutment.

Abstract: A method of preparing a digital model and an artificial tooth applied to dental implant includes the steps of a) combining a jig into a fixture in a patient's oral cavity and scanning the patient's oral cavity by an oral scanner to acquire a first oral digital data and saving it in a computer; b) operating the computer to select one of digital prostheses from a prosthetic database in the computer, arranging a digital positioning jig to correspond to the jig in the first oral digital data, and then combining the selected digital prosthesis with the first oral digital data to generate a second oral data; c) generating a digital oral model based on the second oral digital data; and d) creating a solid oral model.

Abstract: A method for designing a digital abutment for a dental implant includes the steps of: a) implant planning where implant planning is initiated based on digital data obtained from the patient and loaded into a computer system to enable an implant fixture to be implanted at the implant site in the best position, b) establishment of digital reference abutment where a digital reference abutment is established at the implant site and positioned on the implant fixture, c) adjustment of the digital reference abutment where the digital reference abutment has a subgingival part and a supragingival part at the top side of the subgingival part, and the angle between the subgingival part and the supragingival part is adjusted based on the best prosthesis position, and d) finish of digital abutment where the digital reference abutment becomes a digital abutment for placement after the adjustment.

Abstract: A method of generating a digital supplementary device for dental implantation by: preparing a mouth model based on the internal shape of the oral cavity of the patient; performing a 3D scan to obtain digital model of the mouth model, the digital model of the patient's oral cavity and the digital model of the tooth model; defining the digital models as the “positioning object,” “the reference object” and the “attached positioning object”; obtaining characteristic points after joining the positioning object and the attached positioning object and positioning the positioning object and the reference object based on the characteristic points; and then outputting the attached positioning object with the positioning data obtained after positioning of the attached positioning object. The output thus obtained is the desired digital supplementary device for dental implant planning.

Abstract: A method of making a surgical template comprises: producing a 3-D geometrical image by a CT scanning performed on a patient's jaw and establishing corresponding implant planning data to obtain a 3-D first digital image, making a positive plaster model of the patient's jaw, scanning the plaster model to obtain a 3-D second digital image, overlapping the second digital image on the first digital image to obtain a computer representation of the plaster model and at least one implant to be mounted according to the implant planning data, drilling the plaster model to form at least one pinhole according to the implant planning data, inserting a pin into the pinhole, producing a negative template body from an assembly of the plaster model and the pin with a thermoplastic dental material so that the negative template body has at least one implant guide hole and constitutes the surgical template.
