Problems solved by technology

Because the location of impacted teeth is relatively hidden, it is difficult to find them. During extraction, the method of incising the mucosa or removing part of the bone plate is often used to find the impacted teeth. This method has a large wound, and the postoperative healing of the patient is unfavorable and the patient’s discomfort increases.

Embodiment 1

[0037] Such as Figures 1 to 3 As shown, the normal tooth of the present invention is a tooth that erupts normally and will not be extracted when the impacted tooth 11 is extracted. The impacted tooth 11 in the oral cavity is located in the oral mucosa 13 above the normal tooth 12. Due to its position It is high and hidden, and the doctor cannot visually or touch the impacted tooth 11, so the wound is relatively large when the doctor extracts the tooth. The present invention finds the position of the impacted tooth 11 based on the patient's oral surface model and oral CBCT images , and make a guide plate model according to the oral cavity surface model and the oral cavity hard structure model generated by oral CBCT images, so that the produced guide plate 2 can accurately locate the position of the impacted tooth 11, reduce the tooth extraction wound, and reduce the discomfort of the patient. The guide plate 2 is composed of a tooth extraction site positioning part 21 and a gu...

Embodiment 2

[0054] Such as Figure 4 As shown, different from Embodiment 1, the guide plate fixing part 22 of Embodiment 2 is made according to the structural features of the oral mucosa 13 or alveolar bone, and its shape fits the oral mucosa 13 or alveolar bone.

[0055] When the normal teeth 12 are edentulous or completely edentulous, the shape of the guide plate fixing part fits the oral mucosa or alveolar bone at the edentulous part, so as to fix the guide plate fixing part 22 on the mucosa 13 or the alveolar bone.

[0056] The guide plate fixing portion 22 is provided with a guide plate positioning hole, and a nut 221 is fixed on the guide plate positioning hole, and the nut 221 is coaxial with the guide plate positioning hole. A guide plate positioning hole is provided on the guide plate fixing part, and a coaxial nut 221 is arranged thereon, and the bolt 3 is matched with the nut 221 to fix the guide plate on the mucosa 13 or the alveolar bone.

[0057] The guide plate whose shape...

Abstract

The purpose of the invention is to alleviate the discomfort caused by the large wound when the impacted tooth is extracted, and provided are a guide plate for precise tooth extraction, a manufacturingmethod of the guide plate and a use method of the guide plate. The guide plate is composed of a tooth extraction site positioning part and a guide plate fixing part, The shape of the fixing part of the guide plate is fitted to the non-extracted teeth or oral mucosa or alveolar bone, and the guide plate is fixed in the oral cavity. The fixing part of the guide plate is fixed to the non-extracted teeth or oral mucosa or alveolar bone. The fixed part of guide plate can fix the guide plate in the oral cavity, and the position of impacted tooth to be extracted can be determined by the extraction positioning hole, which can greatly reduce the size of wound, alleviate the discomfort of patients after extraction, and accelerate the wound healing.

Description

technical field [0001] The invention belongs to medical auxiliary equipment, and in particular relates to a guide plate for precise tooth extraction, a manufacturing method of the guide plate and a use method thereof. Background technique [0002] Due to the obstruction of adjacent teeth, bone or soft tissue, teeth that can only partially erupt or cannot erupt at all, and will not erupt in the future are called impacted teeth. Tooth cannot erupt to the normal position due to the obstruction of bone, tooth or fibrous tissue, and it is called impacted tooth embedded in submucosal or bone. In mildly impacted teeth, eruption may be slow or misplaced, and in severe cases, teeth may be embedded in the mucosa or bone, that is, embedded impacted teeth. Because the location of impacted teeth is relatively hidden, it is difficult to find them. During extraction, the method of incising the mucosa or removing part of the bone plate is often used to find the impacted teeth. This method ...
