Problems solved by technology

Among them, although the alloy superinlay has good biocompatibility and ductility, its disadvantage is that the aesthetics are insufficient; although the zirconia superinlay meets the requirements in terms of biocompatibility and aesthetics, it has no elasticity and ductility. And it is expensive, so it has not been popularized

Abstract

The invention provides a method for manufacturing an elastic porcelain super-inlay of a fiber post. The method comprises the following specific steps of: (1) carrying out digital scanning impression on a tooth cavity type prepared by cavity type preparation and post channel preparation; (2) directly inserting a fiber post into a prepared post channel, and carrying out digital scanning impression on the tooth cavity type inserted into the fiber post again; (3) according to the digital scanning impression in the step (1) and the step (2), designing an elastic porcelain super-inlay model containing pile holes through CAD and CAM technology treatment, and performing trimming and processing to obtain the elastic porcelain super-inlay with the post holes; and (4) passing the fiber post through a post hole of the elastic porcelain super-inlay, fixing the fiber post on the post hole through adhesive resin, and finally performing polishing. The super-inlay prepared by the method has good beauty, high compressive strength and good ductility, can reduce the abrasion to natural teeth of the jaw, ensures good edge adhesion through digital scanning impression and CAD and CAM manufacturing, has lower price than zirconium dioxide, and has a saving effect.

Description

technical field [0001] The invention relates to the field of dental medical instruments, in particular to a method for manufacturing a fiber post elastic porcelain superlay. Background technique [0002] Restoration of residual crowns of posterior teeth with low occlusal distance (<4mm) has always been a difficult problem in oral clinical restoration due to the serious shortage of repair space. In order to avoid the loss of restorations, the routine restoration procedure is to complete root canal treatment by crown extension surgery Afterwards, the post-core crown was repaired. However, crown lengthening requires flap alveolar bone repair, and the indications are limited by the length of the tooth root. The treatment period is more than 8 weeks, and it is difficult to promote it clinically. A super inlay is a restoration that is embedded in the cavity of the tooth, covers the entire occlusal surface of the tooth and is higher than the occlusal surface, which can change t...
