Upper jaw embedded tooth buccal side admission passage pullout guide plate and manufacturing method thereof

Abstract

The invention relates to an upper jaw embedded tooth buccal side admission passage pullout guide plate and a manufacturing method thereof. The pullout guide plate comprises a dentition supporting part, a guide rod and a positioning ring, the dentition supporting part is provided with a cavity cooperating with the upper dentition of a patient, the inner surface of the positioning ring is an arc-shaped hook face and matched with the radian on the buccal surface of the upper jaw bone of the patient, the positioning ring is connected with the dentition supporting part through the guide rod, and the position of the positioning ring corresponds to the position of a to-be-pulled-out embedded tooth extraction site. The method comprises the following steps that 1:1 three-dimensional model reconstruction is carried out on the upper jaw bone and upper dentition of the patient; according to an upper dentition model, the dentition supporting part is designed; according to the position of the embedded tooth dental crown, a tooth extraction site is determined on the buccal portion of the upper jaw bone model; according to the tooth extraction site and the surface radian of the buccal portion of the upper jaw bone model on the tooth extraction site portion, the positioning ring is designed; the guide rod is designed to connect the dentition supporting part and the positioning ring to form an entirety; and 3D printing is performed to prepare a finished product. The upper jaw embedded tooth buccal side admission passage pullout guide plate and the manufacturing method thereof have the advantages that the tooth extraction site can be positioned accurately and efficiently, the surgical trauma is reduced, and the risks of damaging teeth are reduced.

Description

technical field [0001] The invention belongs to the technical field of extraction of impacted teeth, in particular to a buccal approach extraction guide plate for maxillary impacted teeth and a manufacturing method thereof. Background technique [0002] Impacted teeth refer to the normal position of the teeth due to developmental reasons, and the eruption of the normal time is blocked, or due to the mismatch between the amount of teeth and the amount of bone, resulting in abnormal tooth positions, which often occur in the maxilla due to the narrow position of the jaw and the impacted teeth are normal. The distance between the roots of the teeth is too narrow. In the traditional surgical extraction process, even if there are preoperative panoramic films or CT reconstruction for positioning, it is still inevitable to damage the tooth root or cause a large surgical trauma during the operation, resulting in prolonged healing time and increasing the risk of postoperative infectio...

Problems solved by technology

In the traditional surgical extraction process, even if there are preoperative panoramic films or CT reconstruction for positioning, it is still inevitable to damage the tooth root or cause a large surgical trauma during the operation, resulting in prolonged healing time and increased risk of postoperative infection

[0003] Existing operations rely more on the experience of the operator to determine the three-dimensional position of the supernumerary teeth. The treatment process often involves repeated confirmation of the position before the operation and direct incision. The following problems will occur: first, the positioning deviation of the panoramic film leads to a difference between the real position and the image position after the incision, which increases the risk of root damage during the operation and prolongs the operation time; , accidental fractures may occur; third, when supernumerary teeth are too close to normal teeth, surgical trauma may damage the root
