Methods for fabricating anatomical healing abutment kits and anatomical healing abutment kits

By constructing a database of tooth neck morphology and classification rules, and designing a set of anatomical healing abutment morphology models, the problem of differences between existing healing abutments and natural tooth necks was solved. This achieved high compatibility between the healing abutment and the natural tooth neck and ideal transgingival contour healing, thus improving the restorative effect.

AI Technical Summary

Technical Problem

The existing prefabricated healing abutments differ greatly from the natural gingival contour of the tooth neck, resulting in insufficient support for the gingival papilla, excessive interproximal spaces, food impaction, and difficulty in placement, requiring additional treatment procedures.

Method used

By constructing a database of tooth neck morphology, generating grouping and classification rules, designing a set of anatomical healing abutment morphology models, prefabricating multiple models of finished healing abutment kits, and combining individual patient data for precise matching to select the target finished healing abutment.

Benefits of technology

It achieves a high degree of fit between the healing abutment and the natural tooth neck shape, reduces additional treatment procedures, promotes gingival healing according to the ideal transgingival contour, supports the gingival margin and gingival papilla, and improves the quality of restoration.

Abstract

This application provides a method for fabricating a pre-made anatomical healing abutment kit and the pre-made anatomical healing abutment kit itself. The method includes: generating grouping and classification rules for tooth cervical morphology based on a tooth cervical morphology database; designing and fabricating an anatomical healing abutment morphology model set according to the grouping and classification rules; and prefabricating a pre-made anatomical healing abutment kit containing multiple models based on the anatomical healing abutment morphology model set. The pre-made anatomical healing abutments in the kit have group numbers and models corresponding to the grouping and classification rules. According to the technical solution of this application, the morphology of the critical transgingival region of the healing abutment can achieve a high degree of fit with the ideal transgingival contour, eliminating the need for additional treatment procedures.
