Embodiment Construction

[0025] The technical solutions of the present invention will be further described below in conjunction with the drawings and embodiments.

[0026] Terminology Explanation

[0027] (1) Crown: The part of the tooth exposed in the mouth.

[0028] (2) Artificial crowns, also called braces, are a method used to restore teeth. When the teeth are damaged and difficult to repair by filling the teeth, artificial crowns can be made of different materials and placed on the reduced natural teeth. on the crown.

[0029] (3) Tooth root: The part of the tooth buried in the alveolar bone.

[0030] (4) Abutment tooth: After a part of the natural tooth is worn away, the remaining tooth is used for installing an artificial crown.

[0031] (5) Tooth preparation: The full name is tooth preparation, and the common saying is molar, which refers to the surgical treatment process of natural teeth before artificial crowns are installed.

[0032] (6) Mesial / distal: the direction where the teeth are ...

Abstract

The invention discloses an artificial crown for a maxillary molar. The crown comprises a combined crown prosthesis, wherein an overflow groove is arranged at the gingival end of the combined crown prosthesis, and is used for cleaning the gingival end of the combined crown prosthesis. During use, a channel with two ends communicating with the oral cavity is formed between the overflow groove and the gingiva. The overflow groove is preferably mesial-distal; and during use, the overflow groove is located between the palatine root and the mesiobuccal and distobuccal roots, and the proximal and distal ends of the overflow groove are both palatally presented. By designing the overflow groove at the gingival end, the artificial crown for the maxillary molar is good for self-cleaning of teeth, canremove hidden plaque and tartar, control periodontitis and prevent root caries, and the long-term curative effect of dental root bisection of the maxillary molar is improved.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to an artificial crown for maxillary molars. Background technique [0002] Mandibular molar root division is used to treat third-degree or fourth-degree furcation lesions and fractured teeth. It is to divide the mandibular molar crown and root along the buccolingual groove to form two independent roots. After scraping off the calculus and granulation tissue in the root furcation area, or after root canal treatment, the two "single teeth" will be repaired with post-core and joint crown to evenly distribute the masticatory force and fully mobilize the potential of periodontal tissue. Rhizodivision exposes the diseased tissue, which facilitates the complete removal of pathogenic stimuli, eliminates periodontal pockets, and promotes the attachment of healthy periodontal tissue. It not only avoids the useless alveolar bone atrophy after root extraction, but also retains the feeling of p...
