Problems solved by technology

[0005] Full crown restoration can make the stress disperse evenly and improve the fracture resistance of the remaining tooth tissue. However, due to the high mechanical strength of the full crown restoration, the stress is likely to be transmitted to the root tissue when subjected to occlusal force, and unfavorable fractures increase, causing root fractures. occur, loss of tooth

Embodiment 1

[0033] like figure 1 As shown, this example provides a method for preparing a fibrous band restoration for a penetrating wedge-shaped defect of a maxillary premolar. The fiber band 1 is a commercially available polyethylene fiber band (Ribbond, 14023rd Ave. Suite 1030, Seattle, WA, 98101, USA), including the following steps:

[0034] Step 1. For the affected tooth of the model of penetrating wedge-shaped defect, put the rubber dam on it, open the pulp, rinse with 5.25% sodium hypochlorite, explore the root canal opening, prepare the root canal with 10# and 15# K files, and measure the length with the root canal length measuring instrument. The machine-used Waveone system was used to prepare the root canal to F2, and the length of the film was taken to determine the working length. Clean and disinfect the root canal, dry it, and fill the root canal with hot gutta-percha vertical pressure method. The lingual root canal 4 is filled with gutta-percha tip 3 to 1.0 mm below the roo...

Abstract

The invention discloses a pulp perforation type wedge-shaped defective fibrous band prosthesis for maxillary premolars. The pulp perforation type wedge-shaped defective fibrous band prosthesis for themaxillary premolars comprises fibrous bands and a wedge-shaped composite resin restoration, wherein the number of the fibrous bands is 1 to 2, the lengths of the fibrous bands are smaller than 6.0 to7.5mm of the lengths of teeth, the widths of the fibrous bands are 1.0 to 2.0mm, and the thicknesses of the fibrous bands are 1.0 to 1.5mm. The depth of the wedge-shaped composite resin restoration from the tip to the bottom end is one second to two thirds of the dental diameter of tooth cervix, the width of the wedge-shaped composite resin restoration is the distance between the mesio-adjacent surface and the axiodisto-adjacent surface of the maxillary premolars, and thickness of the wedge-shaped composite resin restoration is 3.0 to 5.0mm; the wedge-shaped composite resin restoration wrapsand winds the one third-mid one third position of a single fibrous band (The formula is shown in the description). The fibrous band prosthesis disclosed by the invention has the advantages that crossbreak of the tooth cervix of pulp perforation type wedge-shaped defective maxillary premolars can be prevented, excessive preparation of teeth subjected to complete coronal restoration is reduced, andmore residual tooth tissues of the pulp perforation type wedge-shaped defective maxillary premolars are retained.

Description

technical field [0001] The invention belongs to the technical field of tooth prosthesis preparation, and in particular relates to a maxillary premolar penetrating wedge-shaped defect fibrous tape prosthesis and a preparation method thereof. This application claims domestic priority. The filing date of the earlier application is August 17, 2017, and the application number is 201710704894.6. Background technique [0002] The incidence of penetrating wedge-shaped defects in maxillary premolars is relatively high. The possible causes include the combination of multiple factors such as weak structure of the tooth neck, mechanical action, acid erosion, stress fatigue, and muscle pressure, which often cause pulp disease and periapical disease. Severe cases lead to transverse fracture of the crown neck. At present, the commonly used clinical treatment method is root canal treatment + post and core + full crown to prevent the occurrence of crown neck fracture. [0003] However, aft...
