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] Such as 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. The affected tooth of the model of the penetrating wedge-shaped defect, the upper rubber dam, open the pulp, rinse with 5.25% sodium hypochlorite, explore the root canal opening, prepare the root canal with 10# and 15# K files, measure the length of the root canal, 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 root canal opening, and the flowable r...

Abstract

The invention discloses a fibrous tape prosthesis for a maxillary premolar penetrating wedge-shaped defect. The fibrous tape prosthetic for a maxillary premolar penetrating wedge-shaped defect includes a fibrous tape and a wedge-shaped composite resin filling body. The fibrous tapes are 1-2, The length of the fibrous band is less than 6.0-7.5mm of the tooth length, the width is 1.0-2.0mm, and the thickness is 1.0mm-1.5mm. The depth from the tip to the bottom of the wedge-shaped composite resin filling body is 1 / 2-2 / 3 of the buccal-lingual diameter of the tooth neck, the width is from the mesio-proximal surface to the distal-proximate surface of the maxillary premolars, and the thickness is 3.0-5.0mm , the wedge-shaped composite resin filling body wraps around the 1 / 3 to middle 1 / 3 junction of the single fiber belt. The fibrous tape prosthesis of the present invention can prevent the neck of maxillary premolars with penetrating wedge-shaped defects from being fractured, reduce the excessive preparation of teeth after full crown restoration, and retain more of the maxillary premolars with penetrating wedge-shaped defects dental tissue.

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...
