Problems solved by technology

[0004] However, due to the traditional root pillars, whether prefabricated single pillars or cast root pillars, the surface of the root pillars must be bonded to the root canal after root canal treatment with adhesives, but only rely on adhesives to join the root After root canal treatment, the overall bonding strength and the stability of the root canal are relatively weak, and it is easy to cause adhesion collapse and failure due to long-term occlusal force wear and tear, which in turn causes the root pillar to loosen and fall off, and the root pillar is combined with the coronary heart. Parts are often fractured due to stress concentration

[0043] refer to figure 1 , is the first embodiment of the prosthetic prosthetic replica device of the present invention, the device includes a column 1 and a coronary heart 2 . The post 1 has a shaft portion 11 and a connecting unit 12 formed on the outer surface of the shaft portion 11. The connecting unit 12 has a plurality of adjacent threads 121. The threads 121 are not limited to concentric circles in this case. And change the type of thread. The coronal core 2 is integrally formed on the upper end of the root column 1, and the coronal core 2 has a head 21 and at least one shoulder 22 formed on the head 21. The maximum outer diameter of the head 21 is larger than that of the root. The maximum outer diameter of the shaft portion 11 of the column 1 . In particular, in this embodiment, the number of shoulders 22 is described as two, but it should not be limited thereto, and the shoulders 22 are all in the shape of an inclined surface.

Abstract

A prosthodontic device applicable to the remainder of a root of a tooth that has received complete endodontic therapy includes a post and a core integrally formed with one end of the post. The post has a post body and a connection unit formed on the surface of the post body. The core has a head to sit on the top end of the remainder of the root of the tooth and at least one shoulder formed on thehead. The largest diameter of the core is larger than the largest diameter of the post body of the post. The prosthodontic device enables rapid completion of tooth preservation and restoration after endodontic therapy, bonding strength between root canals can be strengthened after prosthodontic therapy, and the service life can be prolonged.

Description

technical field [0001] The invention relates to a dental prosthetic prosthetic replica device, in particular to a dental crown restoration kit suitable for root canal treatment, which can quickly carry out subsequent prosthetic prosthetic replica devices. Background technique [0002] Teeth are used for chewing food, if not properly cleaned, it is prone to conditions such as tooth decay and periodontal disease. In addition, teeth are also prone to crown fractures due to accidental impacts. [0003] At present, in the treatment of caries in dentistry, high-speed dental drills are used to debride and grind away the caries, and then use filling materials to restore the teeth. However, in case of severe tooth decay, for example, the pulp cavity has been invaded and decayed, it is necessary to extract the tooth nerve and perform a routine root canal treatment. The root canal was sealed and filled with bacteria, and the follow-up course of crown restoration can only be performed...
