Porcelain tooth with adjustable cantilever and manufacturing process thereof

Abstract

A porcelain crown with an adjustable cantilever is characterized in that the porcelain crown is composed of a porcelain full crown, accessories (an annular belt, a baffle, a spring and a magnet), a receiving slot and a small wrench, all the accessories are assembled into a whole and then fused and attached to the cheek-tongue side of the porcelain crown, then the porcelain crown is sleeved on a prepared abutment tooth in a human body, the annular belt is divided into an inner annular belt and an outer annular belt, and the inner annular belt and the outer annular belt are connected and fixed; a spring is installed between the baffle and the inner ring belt, and a disengaging limiting mechanism is installed between the baffle and the inner ring belt and used for limiting the baffle to be disengaged from the inner ring belt in the sliding direction. And a separation limiting mechanism is also mounted at the contact part of the baffle plate and the receiving slot, and is used for limiting the baffle plate to be separated from the receiving slot in the sliding direction. The baffle is used for shielding the black triangle after being in place to prevent food from being impacted. The porcelain tooth with the adjustable cantilever solves the problem of horizontal food impaction caused by a black triangle after a porcelain crown of a patient is repaired in the prior art.

Description

technical field [0001] The invention relates to the field of oral restoration, in particular to a porcelain tooth with an adjustable cantilever and a manufacturing process thereof. Background technique [0002] The treatment of "black triangle" generally follows a reversible treatment method, and a personalized design treatment plan is selected according to the specific situation of the patient's "black triangle" area. At present, some scholars use the method of injecting a mixture of collagen and platelet concentrate to treat the "black triangle". However, due to the limited sample size and follow-up time of this study, further research is yet to be confirmed. Some scholars cover the "black triangle" with inlays or porcelain crowns after orthodontic gap expansion, and this type of treatment needs to grind away the tooth tissue at the high point of the tooth shape to obtain a "black triangle" At the position corresponding to the shape of the root surface at the tip, the cut...
