Design method and system of a personalized healing abutment

Abstract

The invention discloses a design method and system of an individual healing abutment. The method comprises the following steps: establishing an oral 3D model by acquiring data of teeth and gums on various tooth positions of a plurality of patients, and saving the oral 3D model in a database; according to the oral 3D model in the database, acquiring the shapes and the sizes of tooth roots and tooth necks on the various tooth positions as well as the shapes and the sizes of junction surfaces of the tooth necks and the gums; and according to the shapes and the sizes of the tooth roots and the tooth necks on the various tooth positions as well as the shapes and the sizes of the junction surfaces of the tooth necks and the gums, determining the shape and the size of the bottom of a healing abutment corresponding to the various tooth positions, so that the shape and the size of the base of the healing abutment are identical to the shapes and the sizes of the junction surfaces of the tooth necks and the gums. By virtue of the healing abutment, tissue cuffs formed by the gums, same with that before tooth extraction, can be well matched with a prosthesis which is implanted in a later period, so that the abutment is in smooth transition with the prosthesis, and the problems of black triangle and stress on the abutment are avoided.

Description

technical field [0001] The invention relates to the field of computer-aided design, in particular to a design method and system for a personalized healing abutment. Background technique [0002] After the implant is implanted, the patient will wear a healing abutment on the implant, firstly to protect the implant interface, and secondly to make the gums form a tissue cuff so that the abutment can be put on later. Since the bottom of the traditional healing abutment is a standard round shape, the formed gingival cuff (healed in three months) is also round, which makes the abutment and the restoration too uneven when the restoration is made later, and it is easy to form black triangles and abutments The force problem cannot meet the physiological and aesthetic requirements of the crown. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] In view of the deficiencies in the prior art above, the purpose of the present...
