Description

Installation method of artificial tooth

The invention relates to a method for installing an artificial tooth body by using a customized base entity, in particular to a method for installing a tooth body in which the base entity is fully matched with the shape of the patient's alveolar bone.

Most of the earliest treatments for missing teeth used movable dentures or fixed crowns and gums to treat a wide range of patients with missing teeth. Until recently, the emergence of dental implants allowed patients with missing teeth to choose between single or multiple teeth. Or a full-mouth dental implant.

For patients with sound alveolar bone, dental implants are generally treated with implants installed in the bone. This method is to implant the implants in the alveolar bone of the upper and mandibular tissues, so that the implants form a joint under the gums. Artificial tooth roots, and the appearance, size and type of implants will be selected according to the position of the missing teeth, and different surgical instruments and methods of application will be used to complete the implants. After the artificial tooth root is implanted, the denture is assembled and fixed on the artificial tooth root so that the denture can be stably supported by the artificial tooth root.

However, for patients with alveolar bone atrophy (alveolar bone has been absorbed completely, and the basal bone has been absorbed only a very small amount), it is impossible to use the aforementioned artificial tooth root restoration by piling on the alveolar bone. Generally, it must be reconstructed first. Artificial alveolar bone, implants can only be implanted in the alveolar bone later, but this method of using alveolar bone to rebuild and increase bone is not only complicated in surgical procedures and longer operation time, but also must be customized for special oral cavity In the case of treatment, it cannot be implemented.

In addition, the direction and position of implant implantation is a very important part of the treatment of missing teeth. Implants that are not accurately implanted will cause improper occlusal stress and make the implant easy to fall off. Therefore, perfect preoperative planning and precise surgery Drilling will be an important factor in improving the success rate of patient implants.

However, the two factors mentioned above test the clinical experience and surgical skills of the dentist. If the stability of hand drilling is insufficient, or the visual grasp of the three-dimensional space is not good, it may damage the facial nerve or cause bone fracture. .

Moreover, the metal material of the implant is obviously different from the tissue of the alveolar bone, and it is not easy to tightly join between the two. Therefore, after the artificial root is installed and positioned, it is necessary to wait an additional 3 to 6 months for the restoration of osseointegration. The regeneration of alveolar bone cells causes the alveolar bone to proliferate into the thread gap of the artificial tooth. Therefore, the patient cannot eat food that requires greater bite strength during the restoration time of the implant.

In view of the shortcomings of current implant implantation and alveolar bone reconstruction methods that still have a long time to complete the overall operation, physician experience affects the success rate, and cannot be individually applied to various missing tooth states, it is necessary to innovate artificial teeth. Installation method to improve the aforementioned shortcomings.

The first objective of the present invention is to provide an innovative artificial tooth installation method, which can resist the bite force of chewing food without waiting for the occurrence of Osteointegration when the artificial tooth is installed. This allows patients with dental implants to eat foods that require greater occlusal strength when the implant is completed, which improves the inconvenience of waiting for osseointegration in traditional dental implants.

The second objective of the present invention is that the artificial tooth body can be installed in accordance with various different alveolar bone conditions, whether it is the different positions and shapes of the alveolar bone such as missing teeth, atrophy or healing, the artificial tooth body can be installed stably. , To improve the traditional columnar implant can not be installed on the alveolar bone where the contact area is too small and the supporting force is insufficient, which greatly increases the scope of application of artificial teeth.

The third objective of the present invention is that the artificial tooth body can match the patient’s alveolar bone lack of teeth, and install most dentures in a large area at one time. For example, it can greatly reduce the time required for the patient to implant the tooth and reduce the patient’s suffering. Transition time for missing teeth and inconvenience to eat.

The fourth object of the present invention is that the artificial tooth can be applied to patients with malocclusion, so that the artificial tooth can be installed diagonally with the skewed permanent tooth, so that the artificial tooth can be aligned with the skewed permanent tooth to achieve occlusal chewing action.

The fifth objective of the present invention is to use the currently known biocompatible biomedical materials (such as zirconium dioxide and titanium alloys) that constitute the solid base, locking bone nails, abutments, and dentures that constitute the artificial tooth. The production and installation can be completed directly, without additional use of innovative materials to achieve special conditions of use, so that the dentist can quickly practice the operation.
