Tooth guard plate in periodontal postoperative operation area and manufacturing method thereof

Abstract

The invention discloses a manufacturing method of a tooth guard plate in a periodontal postoperative operation area. The preparation method comprises the following steps: (1) obtaining information ofa periodontal operation area, a rest jaw gap value, jaw position records and an upper jaw impression and a lower jaw impression of a patient, wherein the wax support thickness in the jaw position records is the thickness of the tooth guard plate, and the thickness is based on the residual resting jaw gap which is 0.5-1 mm of the patient after the tooth guard plate is worn; (2) duplicating an upperjaw plaster model and a lower jaw plaster model by using the upper jaw impression and the lower jaw impression; (3) fixing the upper and lower jaw plaster models to a closing frame according to the jaw position records; (4) marking the periodontal operation area on the upper and lower jaw plaster models according to the periodontal operation area information, and uniformly coating plaster slurryin the marked area; (5) manufacturing the tooth guard plate according to a partial denture manufacturing method. The guard plate prepared by the manufacturing method can enable the teeth in the operation area to be naturally suspended without occlusion under the condition of no adjustment, grinding and bonding of the teeth in the operation area, thereby providing an effective guarantee for the healing of the periodontal operation area.

Description

technical field [0001] The invention relates to a tooth guard, in particular to a tooth guard in the periodontal surgery area and a preparation method thereof. Background technique [0002] During periodontal surgery, especially for patients with bone grafting, it takes about 6 months for the teeth and periodontal tissues in the surgery area to heal later. During this period, the teeth in these operation areas should be subjected to as little force as possible, preferably no force. If they continue to function normally and bear the force of chewing, it will seriously affect wound healing. When the patient is awake, he can consciously pay attention to minimize the force on the teeth in the operation area. However, during sleep time, patients will bite involuntarily, especially those who grind their teeth at night, which will cause excessive force on the teeth in the operation area, and even cause the operation to fail. Some doctors will simply protect the surgical area aft...

AI Technical Summary

Problems solved by technology

In addition, the doctor also needs to explain the doctor's order to the patient in particular, and cannot use the teeth in the operation area to chew

[0004] But there are many problems in above-mentioned existing method: 1. Although the occlusal surface of the teeth in the grinding operation area is adjusted, the upper and lower teeth are out of contact, which ensures the healing of the periodontal surgery wound and the success of the operation

Regardless of whether it is to make a crown or restore the adjusted occlusal surface on the denture, the natural teeth in the patient's operation area will be irreversibly damaged, and the restoration of the occlusion in the later stage will result in prolonged treatment and increased costs, adding unnecessary costs to the patient. burden

2. The method of bonding and connecting the teeth in the operation area with resin adhesives often occurs that the bonding breaks and needs to be bonded repeatedly; it is also difficult to clean the teeth in the operation area during the recovery period of the operation; when the operation is successful after 6 months , the removal of the adhesive is also relatively difficult, the tooth surface needs to be polished, and there is also some damage to the patient's natural teeth. At the same time, this method still has the problem that the occlusal surface loses its function and needs to be restored.
