Embodiment 1

[0038] This embodiment provides a method for preparing a fibrous belt restoration of penetrating cracked molars, which includes the following steps:

[0039] Step 1. Simulate conventional root canal treatment: rubber dam on the penetrating cracked tooth, open the pulp, rinse with 5.25% sodium hypochlorite, explore the root canal opening, preliminarily prepare the root canal with 10# and 15# K files, measure the root canal length Long, the root canal was prepared to F2 with the Waveone system, and the length of the root canal was determined by taking a long film. Clean and disinfect the root canal, dry it, use hot gutta-percha vertically pressurized gutta-percha tip 4 to fill the root canal to 1 mm below the root canal opening, seal the root canal opening with glass ionomer 5, and take X-rays to confirm that the root filling is correct.

[0040] Step 2: cleaning, acid etching the cavity, coating the full acid etching adhesive, and curing with light. Take out the fiber tape aft...

Embodiment 2

[0052] Example 2: Fibrous tape inside the medullary cavity perpendicular to the crack Root to rectangular laying + resin filling

Embodiment 3

[0053] Example 3: The fiber tape is laid vertically and horizontally to the crack in the medullary cavity + resin filling

Abstract

The invention discloses an application of a fibrous strip for preparing a pulp-perforation cracked molar repairing body. A crack of a pulp-perforation cracked molar is located at a dental crown occlusion face along a developmental groove in a mesial and distal direction and is parallel to a tooth long axis. The depth of the crack is 1.0 mm from the pulp perforation position to the cemento-enamel junction in a root direction, and the width of the crack is 0.01-0.10 mm, and the thickness of the fibrous strip is 1.0-1.5 mm, and the width is 2.0-3.0 mm. The fibrous strip is located at a dental crown occlusion face in a direction vertical to the crack, or the fibrous strip is located in a medullary space to form rectangular laying, or the fibrous strip is located in a medullary space to form annular laying. The thickness of the fibrous strip is 1.0-1.5 mm, and the width is 2.0-3.0 mm. The fibrous strip is added in a resin repairing body, can improve stress concentration on the tip of the pulp-perforation tooth crack from a maxillary first premolar in a mesial and distal direction, and can efficiently prevent further development of a full crown lower crack. An excellent effect is obtained by performing annular laying of the fibrous strip in a direction vertical to the crack level in a medullary space.

Description

technical field [0001] The invention belongs to the technical field of preparation of tooth restorative materials, and in particular relates to the application of a fiber tape for preparing a pulp-penetrating cracked molar restoration. Background technique [0002] Penetrating cracked molars refer to the cracked molars whose hidden cracks have reached the pulp cavity but have not yet undergone crown-root fracture. It belongs to the late stage of cracked teeth. Symptoms of pulpitis such as excitation pain, occlusal pain, and spontaneous pain often occur or root apex Zhou Yan symptoms. The prognosis of cracked molars is related to the depth of the crack. It is generally believed that the deeper the crack, the worse the prognosis of cracked molars. The direction of cracks in cracked molars was irregular, and could be mesial-distal, buccolingual, or oblique; or two or more directions were involved. About 81.1% of cracked molars were cracks in mesial and distal directions. [0...
