A method for making personalized gingival aesthetically shaped healing abutments

Abstract

The invention relates to a manufacturing method for an individual gingival aesthetic forming healing abutment. The method comprises the following steps: 1) preparing upper and lower jaw models of a patient before operation, shooting CBCT and acquiring Dicom data of upper and lower jaws; 2) scanning the upper and lower jaw models, fitting an acquired STL document with CBCT in a Dicom format and then importing into the implanting guide plate design software; 3) designing an implant three-dimensional position and guide plate and 3D printing the jaw model and guide plate; 4) treating the surface of an end product temporary abutment of a tooth implantation system, in vitro simulating implantation, placing the end product temporary abutment, using an optical scanner for scanning the implant three-dimensional position and importing into the abutment design software; and 5) adopting a CAD / CAM cutting abutment, in vitro splicing, manufacturing a condensate locator and utilizing adjacent teeth to confirm the position of the abutment in the oral cavity. Compared with the prior art, the manufacturing method disclosed by the invention has the advantages that the individual gingival aesthetic forming healing abutment is placed in the same period of implant surgery, the secondary cutting of the wound in the conventional implanting two-stage operation can be avoided, the stimulation to the soft tissues can be reduced, and the like.

Description

technical field The invention relates to a method, in particular to a manufacturing method of a personalized gingiva aesthetically shaped healing abutment. Background technique The implant abutment is an important connection part between the implant and the superimposed prosthetic structure. It has the function of forming the gingival seal and the gingival cuff. Its gingival penetration height, material and shape all have an impact on the health and aesthetics of the implant denture gingival cuff. At present, the finished abutment used clinically has few shapes and angles to choose from, and the scope of modification is limited. The cross-section of the abutment is often circular, which cannot be completely consistent with the shape of the natural tooth neck, and it is difficult to take into account the patient's individual functional and aesthetic needs. At present, the following problems exist in the gingival healing abutment at home and abroad: the diameter of the gingi...

Problems solved by technology

However, some patients still suffer from poor healing, chronic perigingival inflammation, and redness caused by self-curing resin compression pain and the stimulation of monomers released, which affect the smoothness, accuracy, and health of the gingival margin, and prolong the period of time.
