Description

Two-piece root structure improvement

This creation is a kind of root structure, especially a two-piece root structure improvement.

According to the main purpose of artificial dental implants, in order to help patients with missing teeth, artificial teeth can be added between the alveolar of patients with missing teeth, so that patients can use new teeth to chew. The main purpose of artificial implants is to make patients with missing teeth not change their eating behavior or eating habits because of missing teeth. Some people avoid teeth and avoid chewing with missing teeth, leading to teeth on the other side. The frequency of use is higher, and even worse, it can cause facial deformation. Some people avoid brushing the missing teeth, causing the teeth around the teeth to be unhealthy because they are less brushed. These behaviors that change because of missing teeth may seem slight, but over the years, they cause many more serious symptoms.

Therefore, artificial implants can be used to implant the replacement root into the edentulous alveolar by artificial implanting, which not only makes the edentulous alveolar ligament more healthy, but also can correct the artificial implant. Chewing habits.

Although artificial implants have been used for many years, in fact, artificial implants are simply implanted with artificial roots on the tooth bones, so that the artificial roots and the gums can be tightly combined to ensure that the roots are stable (normal conditions need to be 3- 6 months), then put on the artificial crown. Since most of the patient's gums have a tilt angle, most of the upper incisors are tilted, because the one-piece artificial root is limited by the processing method, and the angled one-piece root cannot be processed. therefore One of the existing roots has a fixed angle and cannot match the angle of the teeth of the gums. If it is necessary to have an angle, the special angle roots must be made separately, and the cost and time are relatively high. Therefore, if a two-piece root is used, that is, the artificial root is composed of the base and the crown fixed pillar, but this can solve the one-piece problem, but the thread is used between the base and the crown fixed pillar. It is assembled in a locking manner, and after a long period of use, it is loosened due to frequent chewing and shaking. In addition, it is difficult to control the angle due to the small oral space during installation, and it is difficult to control and fix.
