Description

TECHNICAL FIELD

[0001] The present application relates to the field of dental surgery guide plate, in particular to a minimally invasive osteotomies dental surgery guide plate and its manufacturing method. BACKGROUND

[0002] With the increasing number of people seeking orthodontic treatment, how to shorten the orthodontic treatment has become a hot topic in recent years, and it is also the research focus of researchers;

[0003] Among the methods that can accelerate tooth movement, osteotomies have been proven effective through clinical and basic research, not only accelerating tooth movement, but also effectively increasing the potential for bone formation;

[0004] In its development of a century, with the development of technology, minimally invasive ultrasonic osteotomies are increasingly favored by more and more scholars due to their small trauma, light pain, and good patient applicability. The most serious risk of osteotomies comes from the fact that the operation is only positioned by the experience of the doctor, and cannot be accurately positioned, so the tooth root is damaged. Therefore, using a digital guide plate to guide osteotomies during the operation can greatly increase the success rate of the operation and reduce the risk of the operation. SUMMARY

[0005] The technical problem to be solved by the present application is that the design of the existing osteotomies guide plate is mostly vertical retention or overall positioning, and the soft tissue on the labial side will certainly be concave after positioning, which will lead to inaccurate depth positioning of the ultrasonic osteotome, poor vision, and inconvenience for the clinician to operate and unable to see the soft tissue under the guide plate, which greatly increases the risk of the operation; the tooth support part cannot accommodate the bracket, which makes it impossible for patients who have already bonded the bracket to use the guide plate. However, during the orthodontic treatment process, patients who have undergone tooth extraction often need to perform the initial bracket bonding, alignment, and leveling to close the tooth extraction gap stage. The previous guide plate design did not take into account the needs of such patients. The present application is a minimally invasive osteotomies dental surgery guide plate method, which uses multiple semi-enclosed single-jaw guide plates positioned through the buccal or lingual side and interocclusal retention to form the surgical guide plate, increasing the convenience of positioning the semi-enclosed single-jaw guide plate, achieving a partial positioning design, and facilitating the convenience of the clinician to perform osteotomies, minimizing the concave after the positioning of the surgical guide plate, and further increasing the accuracy of the periodontal minimally invasive osteotomies surgery, facilitating the convenience of clinical operation and the comfort of the patient;

[0006] The semi-enclosed single-jaw guide plate is made of transparent material, which allows the clinician to not only see the semi-enclosed single-jaw guide plate but also operate under direct vision on the soft tissue under the semi-enclosed single-jaw guide plate, further reducing the risk of osteotomies;

[0007] The second fixing position is consistent with the gap between the two adjacent teeth of the patient, so that the fixing is facilitated when the ordinary patient wears the appliance; and the shape of the second fixing position is matched with the bracket, so that the fixing of the orthodontic patient during the treatment can also be smoothly performed.

[0008] The second fixing position cooperates with the first fixing position, and can respectively adhere and fix the oral cavity guide plate from the upper part and the lower part of the tooth, so that the guide plate can be placed in the oral cavity from the buccal side or the labial side of the tooth and adhered to the tooth surface and the gum.

[0009] Compared with the guide plate sleeved from the occlusal surface of the tooth, the guide plate is easy to shake due to the large head and small foot shape of the tooth, and the guide plate is difficult to closely adhere to the gum, so that the position and depth of the surgical incision cannot be accurately controlled.

[0010] CBCT and 3D oral scanning computer simulation are combined to realize the combination of hard and soft tissues of the tooth, the accurate tooth root position and the gap between the tooth roots are determined by CBCT, which is beneficial to accurately design and position the position and depth of the surgical incision, the position of the mucosa is accurately positioned by 3D oral scanning, the guide plate is closely adhered to the mucosa, no gap caused by tissue undercut is generated, so that the incision depth and direction positioning are more accurate, and the defects caused by the prior art are solved.
