Dental Implant Fabrication and Design: Creating Custom Solutions

Dental implants include a titanium member composed of a sintered body made of titanium or a titanium alloy; and a ceramic member composed of an oxide-based ceramic, and a ceramic member fixed to the titanium member. The titanium member has a recess, and the ceramic member has protrusions coupled to the recess and the hole, and the titanium member covers the protrusions of the ceramic member. The protrusion has an increased cross-sectional area, the cross-sectional area of which increases in a direction away from the base end of the protrusion toward the dead end portion of the recess. The titanium component is firmly fixed and joined to the ceramic component in a state where part of the titanium or titanium alloy penetrates into the protruding holes of the ceramic component.

A method of designing a dental implant prosthesis includes the steps of arranging and combining a reference fixture into a fixture installed in a patient's mouth, the reference fixture having at least one characteristic point, the fixture having a connection interface, the reference fixture having A reference fixture relative to the engagement interface; scanning the patient's oral cavity to obtain oral digital data and digital data of the reference fixture having at least one characteristic point digital data; selecting a digital dental implant prosthesis from a prosthesis database in the computer, overlapping the digital teeth The implant prosthesis uses a digital positioning fixture combined with the connection interface, and continues the overlap and positioning data of the digital positioning fixture and the reference fixture numbers to combine the reference fixture digital data into the connection interface; and adjusts the position and size of the digital dental implant prosthesis and angles to obtain the most suitable digital implant prosthesis for the patient.

A method for designing digital abutments for dental implants includes the following steps: a) Implant planning, where the implant plan is initiated based on digital data obtained from the patient and loaded into a computer system to enabling the implant fixture to be implanted b) establishing a digital reference abutment, wherein the digital reference abutment is established at the implantation site and positioned on the implant fixture; c) adjustment of the digital reference abutment, wherein The digital reference abutment has a subgingival part and the angle between the subgingival part and the supragingival part is adjusted according to the optimal prosthesis position, and d) a digital abutment after the digital reference abutment becomes a digital abutment for placement Complete adjustment.
