Design and manufacture method of a restoration-oriented tooth-supported implant surgery guide

Abstract

The invention relates to a designing and manufacturing method of a tooth supporting type implant surgery guide plate for restoration. The method comprises the steps that a plaster model is manufactured; a 5-mm steel ball and a buccal tongue side occlusal pad are manufactured; the thickness of soft tissue at a detection hole is measured; an oral cavity panoramic radiograph or periapical radiograph of a patient with the occlusal pad is shot; measuring and correcting are conducted on the panoramic radiograph; the safe implant bone width in the buccal tongue direction in an implant area is obtained; a final restoration body is designed through a full-anatomical fixed bridge body CAD software; dental crown data is extracted, and the dental crown is uniformly thickened by 3 mm to serve as a retention part of the guide plate; the occlusal surface is modified into a plane perpendicular to the long axis of a replacement body, and the distance of a straight line segment from the plane to the tail end of the replacement body is measured; a three-dimensional digital model with an implant drill bit guide pipe of the guide plate is generated; guide plate processing is completed. According to the method, the near, far and middle direction position, the buccal tongue direction position, the torque angle and the axis inclination of oral dental implant implanting can be precisely guided, the tooth implanting risk is significantly reduced, and the success rate in the initial stage of surgery is increased.

Description

technical field [0001] The invention relates to a design and manufacture method of a dental implant surgery guide plate, in particular to a design and manufacture method of a restoration-oriented tooth-supported implant surgery guide plate. Background technique [0002] Dental implant refers to a method of restoring missing teeth based on the underlying structure implanted in bone tissue to support and retain the upper tooth restoration. It adopts artificial materials (such as metal, ceramics, etc.) way to connect and support the upper part of the dental restoration. Dental implants can achieve a restoration effect that is very similar to natural teeth in terms of function, structure, and aesthetics, and have become the preferred restoration method for more and more patients with missing teeth. Some people call it an important milestone in the field of oral implantology in the 20th century, and praise it for providing humans with a third set of teeth similar to natural den...

Problems solved by technology

If the error is too large, the result after surgery is completely inconsistent with the design plan, which increases the risk of surgery, especially for those cases where the implant is very close to the nerve, the root of the adjacent tooth or close to the bone wall when the plan is designed.

Moreover, it takes time and energy to make the guide plate, which increases the financial burden of the patient and allows the patient to receive more radiation.
