Description

Alveolar bone defect repair kit

The present invention relates to an alveolar bone defect repair kit for use in alveolar bone injuries, in particular to an alveolar bone defect repair kit that can cover the alveolar bone injury, so that the alveolar bone injury can be prevented from being directly exposed to the oral environment, and the healing time of the alveolar bone injury can be relatively increased.

Dental implant is a dental restoration technology to fill missing teeth. When a dentist performs dental implant on a patient, the dentist will implant the artificial tooth root into the alveolar bone of the missing tooth. After the artificial tooth root is tightly combined with the alveolar bone, the dentist can install the denture crown on the artificial tooth root, so that the denture crown installed on the artificial tooth root can have a bite force and fixation force close to that of natural teeth. In addition, the denture crown installed on the artificial tooth root can produce the effect of not falling off and can be used for a long time, making dental implant the best treatment method for patients with missing teeth.

Currently, before dentists perform dental implants on patients, they will first evaluate the patient's alveolar bone condition. If the patient's alveolar bone has severe alveolar bone injuries (such as bone loss or atrophy) due to periodontal disease or tooth loss, the dentist must perform bone filling surgery on the alveolar bone to increase the bone quality of the alveolar bone. This will ensure that when the implant is placed in the alveolar bone injury, there is sufficient bonding strength between the implant and the alveolar bone.

However, when an alveolar bone injury occurs, the dentist will fill the alveolar bone injury with bone powder, and then cover the alveolar bone injury with a regenerative membrane to protect and stabilize the bone powder, thereby promoting alveolar bone hyperplasia. The regenerative membrane is divided into two types: "non-absorbable" and "absorbable". Among them, non-absorbable regenerative membranes are mostly Gore-tex, titanium membrane, etc. Or e-PTFE is the main material, which makes the non-absorbable regenerative membrane thicker, easier to shape and stronger in support. Therefore, the non-absorbable regenerative membrane is less likely to cause side effects after being placed in the human body for a long time. However, when the bone filling surgery uses a non-absorbable regenerative membrane, the non-absorbable regenerative membrane will slow down the blood flow to the alveolar bone, and the regeneration rate of the alveolar bone will be quite slow. The process of regeneration is slow, and even when the implant needs to be implanted into the alveolar bone wound, a secondary operation is required to remove the non-absorbable regeneration membrane. In addition, the absorbable regeneration membrane is made of collagen as the main material, so that when the absorbable regeneration membrane is placed in the patient's body, it can be gradually absorbed by the patient's body over time, and there is no need for a secondary operation to remove the absorbable regeneration membrane. However, the absorbable regeneration membrane has the disadvantages of insufficient support and difficulty in shaping, which makes it impossible for the absorbable regeneration membrane to maintain sufficient space for a long time to allow the alveolar bone to grow, resulting in the absorbable regeneration membrane being absorbed by the patient's body before the alveolar bone completes its growth. Therefore, both the non-absorbable regeneration membrane and the absorbable regeneration membrane are inconvenient to use.

The main purpose of the present invention is to provide a tooth alveolar bone defect repair kit, and the tooth alveolar bone defect repair kit 1 can not only prevent the tooth alveolar bone wound from being directly exposed to the oral environment, but also shorten the time of healing the tooth alveolar bone wound 31.

To achieve the above-mentioned purpose, the alveolar bone defect repair kit of the present invention is applied to a alveolar bone having an alveolar bone wound, wherein the alveolar bone defect repair kit is mainly composed of a bone drilling tool and a defect cover.

The bone drill tool is provided with a handle and a stop plate in sequence along a drill axis, and a plurality of cutting blocks protrude from the stop plate. The plurality of cutting blocks are arranged in a ring-shaped interval with the drill axis as the axis, so that the innermost sides of the plurality of cutting blocks form an uncut area. At the same time, the plurality of cutting blocks jointly build a cutting area surrounding the outer periphery of the uncut area, and the uncut area and the cutting area together form a three-dimensional repair space.

The above-mentioned defect cover is used to cover the above-mentioned alveolar bone wound, and the shape of the above-mentioned defect cover matches the above-mentioned three-dimensional repair space.

In this embodiment, each of the cutting blocks can cut the alveolar bone around the alveolar bone wound to produce bone chips, thereby forming a cutting hole in the alveolar bone with a contour larger than the alveolar bone wound, and the shape of the cutting hole matches the three-dimensional repair space.

When the plurality of cutting blocks cut the alveolar bone, the uncut area is located opposite to the alveolar bone wound, and each cutting block is provided with a chip row surface to guide the bone chips to the uncut area, so that the bone chips can be moved into the interior of the alveolar bone wound. In addition, the contour of the stop plate is larger than the three-dimensional repair space, and when the entire cutting block is located inside the cutting hole, the stop plate will contact the alveolar bone, and the defect cover can fill the cutting hole, so that the surface of the defect cover can be aligned with the surface of the alveolar bone.

Furthermore, the defect cover is made of a bioabsorbable material or a biocompatible material, so that the defect cover can be absorbed by the human body, wherein the bioabsorbable material includes tricalcium phosphate, and the biocompatible material includes polylactic acid, and the outline of the three-dimensional repair space is between the outline of the handle and the outline of the stop plate.

The feature of the present invention is that the shape of the defect cover matches the three-dimensional repair space of the bone drill. When the bone drill of the alveolar bone defect repair kit cuts the alveolar bone around the alveolar bone wound through a plurality of cutting blocks, a cutting hole with a shape matching the three-dimensional repair space is formed in the alveolar bone. Next, the defect cover of the alveolar bone defect repair kit is placed inside the cutting hole, so that the defect cover can not only cover the alveolar bone wound but also fill the cutting hole. In this way, the defect cover prevents the alveolar bone wound from being directly exposed to the oral environment, which can relatively shorten the healing time of the alveolar bone wound.

In order to facilitate a deeper and more detailed understanding of the structure, use and features of the present invention, a preferred embodiment is provided and described in detail with reference to the drawings as follows:
