Problems solved by technology

If the adjacent area of ​​the affected tooth is damaged after carious tissue removal and tooth preparation, it will lead to poor shape of the adjacent area after filling, poor shape of the outreach gap, and poor contact of the adjacent area, resulting in food impaction, filling body fracture, etc. complication

Embodiment Construction

[0029] In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific embodiments are described in detail in conjunction with the accompanying drawings.

[0030] The schematic diagram of the personalized proximal surface forming system of the present invention is as follows figure 1 As shown, it includes a watercress forming sheet 1 , an interproximal wedge 2 , a retaining ring 3 , a rubber dam 4 and a flowable resin 5 . Among them, a rubber dam is used to isolate the affected tooth, and the placement of the rubber dam clip must not hinder the placement of the watercress forming sheet. This step is used to prevent moisture, isolate infection, prevent swallowing and aspiration, and clear vision. Between the interproximal wedge and the watercress forming sheet, it is used to closely fit the watercress forming sheet on the tooth surface of the target tooth; inject the flowable resin around the foot of the retainin...

Abstract

The invention discloses an individualized proximal surface forming system, a preparation method thereof and a method for auxiliarily filling an offending tooth. The filling method comprises the following steps that (1) the proximal surface of the offending tooth has caries while the dissected appearance is intact, or tooth defect exists, and then the appearance is rapidly recovered by using glassionomers; (2) the individualized proximal surface forming system of the offending tooth is prepared; (3) the caries of the offending tooth is removed, and the tooth body is prepared; (4) the individualized proximal surface forming system is reset, that is, a retention ring along with cured flowing resin are reset at the target offending tooth, so that a bean-shaped forming sheet is tightly attached to the position between the offending tooth and the flowing resin; and (5) the target offending tooth is filled with resin, the resin filling material being subjected to illumination curing is occluded and adjusted, the occlusion interference point is ground and removed, and the resin filling material is polished. The method can restore the original proximal surface contact relation and the abduction gap anatomic form of the offending tooth, the grinding and adjusting time after filling is shortened, and the filling postoperative complications such as food impaction, obturator overhang and obturator fracture are reduced.

Description

technical field [0001] The invention belongs to the field of dental pulp and endodontics, and the specific technology relates to a personalized adjacent surface forming system and a method for preparing and assisting filling of affected teeth. Background technique [0002] At present, the treatment method for carious teeth is mainly resin filling treatment. For the caries of the proximal surface of the posterior teeth, the resin filling involves the problem of the formation of the proximal surface. The commonly used clinically used proximal surface forming system is the watercress forming sheet system. The watercress forming sheet system is suitable for carious lesions on the proximal surface of the affected teeth, but it is required that the carious tissues of the affected teeth are removed and the adjacent area is not damaged after tooth preparation. If the adjacent area of ​​the affected tooth is damaged after carious tissue removal and tooth preparation, it will lead to...
