Description

Bone prosthesis

This creation is about an artificial tooth body that can be customized for different patients, especially a bone-bonding artificial tooth body that is firmly coupled with an alveolar bone that shows atrophy.

The earliest treatment of edentulous teeth mostly uses movable dentures or fixed crowns and gums to treat patients with a large range of edentulous teeth. Until the recent appearance of dental implant technology, patients with edentulous teeth can choose to perform single, multiple or It is the planting of full-mouth teeth.

For patients with healthy alveolar bones, the general method is to use dental implants with implants installed in the bone, and the treatment of implants is to implant the implants in the alveolar bone of the upper and lower jaw tissues, so that the implants An artificial root is formed under the gum, and the appearance, size and type of the implant will be selected according to the position of the missing tooth, and combined with different surgical instruments and application methods to complete the implantation. After the artificial root is implanted, , Assemble and fix the denture on the artificial tooth root, so that the denture can be firmly supported by the artificial tooth root on the alveolar bone.

However, for patients with alveolar bone atrophy (alveolar bone has been absorbed and the basal bone has also been absorbed with a very small amount), it is impossible to implant implants on the alveolar bone in the atrophy state. Atrophic patients generally need to reconstruct artificial alveolar bone against the atrophic alveolar bone, and then they can implant the implant into the artificial alveolar bone, and this method uses alveolar bone reconstruction to increase bone Not only is the surgical procedure complicated and the application time is long, but it is impossible to perform the operation for the special oral cavity where it must be customized.

In addition, the direction and position of the implant is very important for the treatment of missing teeth. Failure to accurately implant the implant will result in malocclusion of the upper and lower dental arch, making the implant easily fall off the alveolar bone. Therefore, the perfect Preoperative planning and precise drilling during surgery will be an important factor in improving the success rate of patients' dental implants.

However, both of the above two factors test the clinical experience and surgical skills of the dentist. If the stability of the free-hole drilling is insufficient, or the visual mastery of the three-dimensional space is poor, it may damage the facial nerve or cause bone fracture. .

Furthermore, the metal material of the implant is obviously different from the tissue of the alveolar bone, and it is not easy to tightly connect the two. Therefore, after the artificial tooth root is installed and positioned, it must wait an additional 3 to 6 months for the recovery time of bone integration. The regeneration of alveolar bone cells causes the alveolar bone to proliferate into the thread gap of the artificial tooth body. Therefore, the patient still cannot eat food that requires a large bite force during the recovery time of the implant.

In view of the current shortcomings such as implant implantation and alveolar bone reconstruction, the overall surgery completion time is relatively long, the doctor’s experience affects the success rate, and it cannot be applied to various missing teeth. It is necessary to innovate artificial teeth. Improve the aforementioned deficiencies.

The main purpose of this creation is to improve the structure of artificial dental bones. After the artificial dental bones are installed in the alveolar bone of the patient, the artificial dental bones can immediately produce support against the bite force of chewing food, so that the patient does not need to wait. Osteointegration occurs in the alveolar bone, so that patients can eat foods that require a large bite force when the implant is completed to improve the inconvenience of waiting for the time of bone integration in traditional implants.

The secondary purpose of this creation is that the artificial tooth can be installed in various atrophic alveolar bones, and then the alveolar bones of different positions and shapes such as incisors, canines or molars can be assembled with the artificial tooth body, resulting in improvement Traditional columnar implants cannot be installed on alveolar bones where the contact area is too small, resulting in insufficient support, and the scope of application of artificial teeth is greatly increased.

Another purpose of this creation is that the artificial teeth can be applied to patients with malocclusion, so that the artificial teeth can be set obliquely with the skewed permanent teeth, so that the dentures can be aligned with the skewed permanent teeth to achieve the chewing action.

Another purpose of this creation is to construct the base, bone fixation nails, dentures and other components of the bone-attached artificial tooth body, which can be directly completed by using the currently known biocompatible biomedical materials (such as zirconium dioxide and titanium alloy) Production and installation, no need to use additional innovative materials to achieve special conditions of use, so that dentists can quickly practice.

In order to achieve the aforementioned purpose, the original bone-bonding artificial tooth body is set on an alveolar bone, and a partial section of the alveolar bone shrinks to form a peak, and the bone-bonding artificial tooth body includes: a base, a denture and A locking bone nail.

In addition, the bone-bonding artificial tooth body further includes an auxiliary bone nail penetrating the locked part, the locking Both the bone nail and the auxiliary bone nail penetrate from the lower connection portion to the peak portion, or the locking bone nail penetrates from the lower connection portion to the peak portion, and the auxiliary bone nail penetrates from the peak portion at the same time Into the lower connection.

In this embodiment, the threading direction of the locking bone screw into the locked portion is parallel to the threading direction of the auxiliary bone screw into the locked portion, and the locking bone screws are arranged at intervals in the longitudinal direction For the above-mentioned auxiliary bone nails.

In another preferred embodiment, the lower connection part has a first lower connection block and a second lower connection block arranged at intervals between the first lower connection block, the first lower connection block and the second lower connection block They are respectively located on opposite sides of the contact surface, so that the peak portion is on the first lower connection block and the second lower connection block.

In the foregoing two embodiments, the denture includes a support portion and a tooth portion, the support portion has a first end and a second end on opposite sides, the first end is connected to the connection surface, and A tooth covering the alveolar bone is adjacent, and the tooth portion is connected to the second end.
