A kind of framework and crown denture structure and its installation method

Abstract

The invention relates to a skeleton crown-connected false tooth structure. The skeleton crown-connected false tooth structure is used for restoring three deleted crown-connected teeth, two lateral tooth deletion sides are implanted, the middle false tooth of the crown-connected false tooth structure is connected with tooth roots of two lateral tooth implanting structures through a skeleton, the middle false tooth is fixedly arranged on the skeleton, and a tooth slit is kept between the middle false tooth and each of two lateral false teeth; and force applied to the middle false tooth is conducted to the tooth roots of the two lateral tooth implanting structures through the skeleton in the chewing process. The structure can well solve the disadvantages of routine crown connection structures when a crown-connected false tooth structure is must be used.

Description

technical field [0001] The invention relates to a tooth implant structure and method, especially a crown structure. Background technique [0002] Clinically, many porcelain teeth with continuous crowns can be seen. The most common one is to restore a missing tooth with 3 consecutive crowns, and there are also implanted teeth with continuous crowns. It has some disadvantages: [0003] 1) Uncomfortable, normal natural teeth are single, and each tooth has normal physiological mobility. It is not immobile on the gums. The continuous crown connects several teeth together, so that when the force is applied, several teeth are stressed at the same time, causing the teeth to feel abnormal, a bit like wearing a magic spell, airtight. [0004] 2) Unsightly, the normal anterior teeth adjoining relationship is a point contact, and the position of each tooth contact point is different. This results in a well-proportioned abduction space and gingival papilla shape. However, the large-...

Problems solved by technology

[0004] 2) Unsightly, the normal anterior teeth adjoining relationship is a point contact, and the position of each tooth contact point is different

However, the large-area connection of the anterior teeth with porcelain crowns seriously damages the beauty of the anterior teeth.

[0005] 3) It is not conducive to tooth cleaning, and the continuous porcelain teeth cannot use dental floss to clean the adjacent space normally

[0007] 5) It is not easy to repair. Porcelain teeth will definitely be damaged during use, such as stretched porcelain, secondary dental caries, dental nerve infection, etc.

However, the continuous crown and porcelain tooth will affect the whole body, and it is likely to need to be completely removed.

The economic loss of the patient is also great

[0008] 6) It is prone to various problems. Porcelain teeth with continuous crowns are subjected to different forces from all directions in the oral cavity

[0009] But sometimes, it is necessary to use the continuous crown structure. For example, if three teeth are missing in a row, if all the teeth are implanted, the trauma may be greater, the human body is not easy to accept, and the effect of the implant is not very good; teeth, alveolar bone is not suitable for implants, etc.
