All-porcelain tooth preparation method

Abstract

The invention discloses an all-porcelain tooth preparation method. The method comprises the following steps: firstly providing a seating path; then providing edge lines so that the edge lines are located at the most protuberant point of a neck edge; and then providing a seating parameter; establishing a full crown shape according to all-porcelain conditions; drawing an incising line so that: anterior: at a buccal side and a lingual side, the incising line is located above a neck-edge line for 1.5-2 mm and is parallel to the neck-edge line, and mesial and distal incising lines are located belowa contact point; posterior: at the buccal side and the lingual side, the incising line is located above the neck-edge line for 1.5-2 mm, and mesial and distal incising lines are located below the contact point; and then providing an incising parameter so that the compensation parameter of the anterior is half of an occlusal space, and the compensation parameter of the posterior is half of the occlusal space; an incising amount being 0.5 mm and re-trimming an incising crown; establishing a connector between two adjacent tooth; and finally performing handmade porcelain. The invention greatly improves the strength of dental crown, simultaneously avoids the occurrence of translucency in the case of insufficient tooth preparation, and accelerates the production efficiency of all-porcelain tooth.

Description

technical field [0001] The invention relates to a method for making dentures, in particular to a method for making all-ceramic teeth. Background technique [0002] In the traditional production process of all-ceramic teeth, only a zirconia sub-crown of uniform thickness is established on the surface of the abutment teeth, and on this basis, porcelain powder is piled up and sintered to obtain all-ceramic teeth. Due to the use environment and individual differences (individual differences include the difference in the amount of teeth adjusted by the clinician or the position and size of the patient's teeth), the support of the local crown will be insufficient, resulting in frequent porcelain collapse in the patient's mouth. , bringing losses and troubles to patients and clinics. [0003] In addition, in the traditional production process of all-ceramic teeth, a large amount of porcelain powder is piled up by hand, and there are many steps and processes.

Due to the use environment and individual differences (individual differences include the difference in the amount of teeth adjusted by the clinician or the position and size of the patient's teeth), the support of the local crown will be insufficient, resulting in frequent porcelain collapse in the patient's mouth. , bringing losses and troubles to patients and clinics

[0003] In addition, in the traditional production process of all-ceramic teeth, a large amount of porcelain powder is piled up by hand, and there are many steps and processes. It is difficult to control the shrinkage ratio of the porcelain powder, and it is difficult to control the color and luster. Low
