Metal-porcelain dental root crown and method for manufacturing same

Abstract

The invention relates to a metal-porcelain dental root crown and a method for manufacturing the same. The method includes steps of a, acquiring oral cavity data of a patient by the aid of reverse engineering before and after the teeth of the patient are ground; b, modeling porcelain dental crowns according to the oral cavity data before the teeth are ground; c, optimally designing occlusal contact points of porcelain dental crown models; d, building root crown three-dimensional models according to the steps b and c; e, importing the root crown three-dimensional models into control computers and manufacturing additives for a root crown. The metal-porcelain dental root crown and the method have the advantages that the oral cavity data of the patient are acquired before and after the teeth are ground, so that the porcelain dental crowns and the root crown can be modeled, the metal-porcelain dental root crown can be highly matched with the oral cavity of the patient, acting force applied by the patient to the oral cavity after the teeth are ground can be reduced to the greatest extent, and the purpose of recovering the mastication ability to the greatest extent can be achieved; the method can be applied to manufacturing the metal-porcelain dental root crown.

Description

technical field

[0001] The invention relates to the field of artificial dental implants, in particular to a method for manufacturing a metal-ceramic dental crown and the dental crown. Background technique

[0002] Porcelain teeth are mainly used in tooth restoration, so that patients can obtain better chewing ability and more beautiful teeth. It first grinds off the crown of the tooth to be repaired by the patient, and then makes a new crown by fusing ceramics on the bottom crown and wears it to achieve tooth restoration. The metal fusion-bonded porcelain crowns used clinically are mainly divided into precious metals and non-precious metals. Precious metals include high-gold and low-gold, and most of them are mixed with palladium and platinum as alloys; non-precious metals are mainly nickel-chromium alloys, pure titanium, etc.

[0003] In the existing technology, the manufacture of the bottom crown is mainly done by melting and molding. The general steps are: making a plast...
