Abstract
The present invention relates to dental implants, and more particularly to custom dental implant fixture that shortens the extraction to completed restoration period from 6-8 months to 4 months. The invention is to use the existing extraction site as is to place custom implant fixture, thereby avoiding a lengthy extraction healing stage and the subsequent osteotomy surgery.
Claims20
A method of performing dental implant using a custom implant fixture to shorten the extraction to completed restoration period, which comprises:
- taking an impression after a tooth being extracted to capture the extraction socket, teeth adjacent to the extracted tooth, soft tissue and the opposing dentition and sending the impression to a lab for designing and fabricating a custom implant fixture system including a custom implant fixture and abutment;
- filling the extraction socket site with a solid socket space maintainer to prevent the bone from filling in before an implant fixture placement;
- removing the temporary socket maintainer and cleaning the socket;
- placing the custom implant fixture into the extraction socket;
- placing the abutment onto the custom implant fixture;
- and
- placing a crown onto the abutment.
4 more elements
A system for dental implant comprising:
- a custom implant fixture;
- and
- a custom abutment/implant transfer;
- wherein the custom implant fixture is designed as an exact negative of the bone socket site of an extracted tooth based on an impression and which is a block made of titanium with an apical end and an abutment end and which has grooves on the block to increase surface area with bones and a internally threaded screw hole open to the abutment end for receiving an abutment screw and which is coated with osteointegration materials;
- and the custom abutment/implant transfer is designed and fabricated based on the impression.
2 more elements
A method of designing and fabricating a custom implant fixture and abutment, which comprises:
- taking an impression after a tooth being extracted to capture the extraction socket, teeth adjacent to the extracted tooth, soft tissue and the opposing dentition;
- designing and fabricating a custom implant fixture using the information obtained from the impression using CAD/CAM software, wherein the custom implant fixture is designed as an exact negative of the bone socket site and which is a block made with titanium with an apical end and an abutment end and which has grooves on the block to increase surface area with bones and a screw hole on the abutment end for receiving an abutment screw and which is coated with osteointegration materials;
- and
- designing and fabricating a custom abutment/implant transfer with the option for a fixture analog in the CAD/CAM software based on the impression information;
- wherein the custom implant fixture is stabilized during the osteointegration period by compressing the bone around the implant.
