Finished holdable resin-bonded sheet, method for producing the finished holdable resin-bonded sheet

Abstract

The invention relates to the medical field, and in particular to a finished holdable resin bonded sheet for treating food impaction and a method for making the finished holdable resin bonded sheet. The finished product can hold the resin bonding sheet including handle and bonding sheet, and bonding sheet comprises sheet-shaped main body and the protuberance that can be broken by extending outwards from the peripheral edge of sheet-shaped main body; It is light-cured together with one end of the handle. The method includes overmolding the light-curing resin to form a sheet-like part and a protrusion extending outward from the periphery of the sheet-like part, and connecting the protrusion with one end of the handle; Light-curing until the butted protrusions and one end of the handle are light-cured together; wherein, the sheet-like part forms a sheet-like main body, and the protrusion forms a protrusion. The finished resin bonding sheet of the present invention can fill the excessively large interdental spaces, and is especially suitable for treating vertical food impaction with complete dental tissue and no abnormal anatomical structure.

Description

technical field [0001] The invention relates to the medical field, in particular to a finished product holding resin bonded sheet for treating food impaction and a method for making the finished product holdable resin bonded sheet. Background technique [0002] Food impaction is a common clinical disease. This concept was first proposed by foreign scholar Hirshfeld in 1930, that is, during the chewing process, food enters the interdental space under the action of occlusal force or buccolingual muscles. Generally speaking, when the patient eats, the gap between the teeth is embedded in the food, causing pain and discomfort, bad breath, caries, gingivitis and periodontitis, etc., affecting eating and greatly disturbing the daily life of the patient. [0003] Food impaction is a complex disease with multiple etiologies. Problems of the nose, tongue or (occlusion) can cause food impaction. However, many reports have pointed out that there is a direct and positive relationship be...

AI Technical Summary

Problems solved by technology

This method can detect obvious abnormalities such as interference points, early contact points, sharp cusps or marginal ridges, but in some cases of food impaction caused by teeth without abnormal shapes, obvious problems in the occlusal system cannot be detected

[0013] The advent of the optical (occlusal) method in the early 1980s provided a visually observable and recordable occlusal analysis technique for occlusal examination. However, in the clinical application of this technology, the optical (occlusal) recording method still has time-consuming and accurate Poor degree, low efficiency and other problems

In 1998, Xu Jun et al. reported the study of optical (occlusal) instrument to guide adjustment (occlusion), but optical (occlusal) instrument can only estimate the force ratio between the mesial and distal surfaces of teeth, and cannot guide fine adjustment (occlusion). )

[0014] (2) Limitation of therapeutic effect

[0015] At present, there are very limited literature reports on the long-term efficacy of dental impaction surgery in the treatment of food impaction. According to the author's years of clinical observation, it is not easy to adjust the grinding position accurately, and the grinding volume is not easy to quantify. In addition, stable occlusion It is the result of the adjustment and adaptation of joints and muscles. Each micro-adjustment will affect the muscles and joints of the oral and jaw system and cause corresponding changes.

Its curative effect is uncertain, and some cases relapse after treatment

[0016] (3) The course of treatment is long and the number of follow-up visits is high

Inlay restoration can well solve the problem of food impaction caused by the defect of the adjacent or adjacent (occlusal) surface, but it needs to grind away the tooth tissue. For teeth without obvious defects, this restoration method is obviously contrary to restorative science In principle, no inlay restoration has been proposed at home and abroad for food impaction treatment of intact teeth

[0027] (2) Limitations of technical means

For example, there are still a large number of patients with food impaction in clinical practice. The dental tissue of the impacted teeth is complete and there is no obvious abnormal anatomical structure. The application of adjustment (occlusal) surgery is limited. At present, there are no treatment measures at home and abroad that can definitely improve their symptoms.
