Mounting method of resin try-on crown and all-ceramic preformed crown thereof

Abstract

The invention belongs to the technical field of dental restoration, and particularly relates to a mounting method of a resin try-on crown and an all-ceramic preformed crown thereof. The method specifically comprises the steps: (1) manufacturing a resin try-on crown through a 3D printing technology according to design data of an all-ceramic preformed crown, wherein the size of the resin try-on crown is the same as that of the all-ceramic preformed crown; (2) selecting a proper resin try-on crown for try-on according to teeth and sizes of the teeth, and acquiring a proper model of the resin try-on crown after try-on for multiple times; (3) according to the obtained proper model of the resin try-on crown, selecting an all-ceramic preformed crown with the same model as the resin try-on crown,directly mounting the all-ceramic preformed crown on a deciduous tooth, and performing slight adjustment; and (4) performing cementation at the periphery of the deciduous tooth provided with the all-ceramic preformed crown. The resin try-on crown comprises a crown body and at least two protrusions, and the protrusions are arranged on the surface, except surfaces where the crown body contacts withadjacent teeth. The method has the beneficial effects that the method can improve one-time completion efficiency of the all-ceramic preformed crown, and the all-ceramic preformed crown is convenient to manufacture, low in cost and convenient to use.

AI Technical Summary

Benefits of technology

This patented method involves making ceria or zirconium oxide (ZrO2) fillings on an aluminum base that are then ready for immediate mounting onto teeth. These filled materials have excellent flexibility but also very strong properties when worn out properly by dentists who want them to be able to make changes without damaging their surrounding tissues over time. By selecting different sizes based on how well they fit into place with these new material, there will be fewer issues involved before final fitting. Additionally, this method allows users to customize the shape of each filling piece individually while maintaining its strength against external forces like impact force from brushing across the surface being restored. Overall, this approach simplifies the overall structure design and makes maintenance easier compared to traditional methods involving metal restoration techniques.

Problems solved by technology

This technical problem addressed in this patents relates to promoting proper placement of ceramics within childhood teeth while maintaining effective protection against cavitation caused by acid etchants without causing damage to sensitive areas around these teeth. Previous attempts at making prostheses were unsatisfactory because they had poor durability and could break down easily overtime. Therefore, new methods must overcome issues associated with current options including lack of suitable alloys, difficulty in selecting different types of alloy cements, potential hazards involved, etc., resulting in improved performance and reduced costs compared to existing alternatives.
