Description

Improvement of root structure

The invention relates to an improvement of a root structure, in particular to a two-piece improvement of a root structure.

The main purpose of artificial tooth implantation is to help patients with missing teeth, so that artificial teeth can be added between the alveolar spaces of patients with missing teeth, so that patients can chew with new teeth. The main purpose of artificial tooth implantation is to prevent patients with missing teeth from changing their eating behaviors or eating habits due to missing teeth. Some people who lack teeth avoid chewing on the missing teeth, which leads to the other side of the teeth. The frequency of use is high, or even it will cause face deformation. And some people avoid brushing the missing teeth, which causes the teeth around the missing teeth to be unhealthy because of less brushing. These changes in behavior due to missing teeth may seem minor, but over the years, they cause many more serious symptoms.

Therefore, artificial implants can be used to artificially implant alternative tooth roots into the alveolar areas of missing teeth, which not only makes the alveolar gums of missing teeth healthier, but also can correct artificial teeth. Chewing habits.

Although artificial implants have been used for many years, in fact, in short, artificial implants are implanted into the tooth bone, so that the artificial tooth root and the alveolar bone can be tightly combined. 6 months), and then covered with artificial crown. Because most patients' gums have an inclined angle, especially in the position of the upper incisors, most of them are inclined, because generally The one-piece artificial root is limited by the processing method and cannot produce an angled one-piece root. Therefore, the existing one-piece root cannot match the angle of the first tooth of the gum. If an angle is required, a special angle root must be made separately. In this way, its cost and time are relatively increased. Therefore, if a two-piece tooth root is used, that is, the artificial tooth root is divided into a base and a crown fixed pillar, but this can solve the one-piece problem, but because the base and the crown fixed pillar are commonly used, Assembled in a screw-locked manner, after a long period of use, it may loose due to frequent chewing vibrations. In addition, due to the small oral space during installation, it is difficult to adjust the angle and is difficult to control. fixed.

The second beveled edge 2224 abuts the first beveled edge 1204 to restrict the crown fixing. The pillar 2 rotates, and the second short side 2220 is on the same side as the first long side 1202, and the second long side 2222 is on the same side as the first short side 1200.

Please refer to FIG. 3 and FIG. 8 together, which are schematic cross-sectional structural diagrams of the artificial dental crown installation according to the present invention. As can be seen from the figures, the crown fixing pillar 2 defines a second centerline 24 and the base 1 defines a first centerline 14 forming an inclined angle 26 with the second centerline 24, and the crown fixing pillar 2 pairs the base The inclination angle 26 of 1 is generally between 15 ° and 20 inclination angle 26. During installation, the base 1 is first locked in the gum 3 through the threaded portion 10, and then a crown fixing pillar 2 of an appropriate angle is selected to be installed on the base 1. For the installation method, please refer to the subsequent detailed description, and then fixed in the crown. An artificial crown 4 is established on the pillar 2. As for the artificial crown 4 part, a temporary artificial crown 4 is established before the flesh is covered. After the tooth is covered, the permanent artificial crown 4 is replaced. As a result of the two-piece structure of the base 1 and the crown fixing pillar 2, the teeth with different inclination angles to the base 1 can be selected according to the inclination angle of the patient's gum. The crown fixing pillar 2 improves the correctness and stability of the installation angle.

Please refer to FIG. 5, FIG. 6 and FIG. 7 together, which are schematic diagrams of the action of the locking structure inserted into the buckle slot of the present invention, the schematic diagram of the planar action of rotating the crown fixing pillar, and the planar action of the fixed block and the fixed projection. schematic diagram. Since each fixing block 120 is located in the buckling groove 12, in order to clearly understand the operating relationship between the fixing block 120 and the fixing structure 22, only the plan view of the fixing block 120 and the fixing structure 22 is used as an illustration. The base 1 is fixed to the gum with the threaded portion 10, and then the dental crown fixing pillar 2 is inserted into the buckle groove 12 through the locking structure 22, and each of the fixing protrusions 222 in the locking structure 22 will be inserted along the insertion space 121 when being inserted. Insert, when the fixed convex part 222 is turned to the end, the crown fixing pillar 2 is rotated to move the alignment space 224 to each fixing block 120. When the fixing block 120 is located in the alignment space 224, the first beveled edge 1204 on the fixing block 120 will abut. Press the second beveled edge 2224 on the fixed convex portion 222 and press the crown fixing pillar 2 toward the base 1 to increase the frictional resistance of the crown fixing pillar 2 toward the base 1 to limit the crown fixing pillar 2 After the rotation, the fixed block 120 and the fixed convex portion 222 are aligned and fixed, the second short side edge 2220 is on the same side as the first long side edge 1202, and the second long side edge 2222 is on the same side as the first short side edge 1200.

It can be known from the above structure that the present invention can strengthen the tightness and structural stability of the card fixing structure 22 after it is inserted into the buckle groove 12. It is worth mentioning that because the base 1 and the crown fixing pillar 2 are two-piece structures, depending on the needs, the crown fixing pillar 2 with different tilt angles to the base 1 is selected to enhance convenience without being restricted. In addition, the dental crown fixing pillar 2 is easier to install and fix and to grasp the position when the oral cavity is installed in a small space.

The above-mentioned embodiments are merely illustrative for explaining the principle of the present invention and its effects, and are not intended to limit the present invention. Anyone familiar with the art can modify the above embodiments without departing from the spirit and scope of the present invention.
