Method for designing and manufacturing repair-orientated planting bone augmentation guide plate

Abstract

The invention relates to a method for designing and manufacturing a repair-orientated planting bone augmentation guide plate. The method comprises the following steps: shooting CT of a patient to obtain a planting three-dimensional space; carrying out intraoral three-dimensional scanning or scanning a gypsum model to obtain patient data; fusing the two parts of data; designing missing teeth and a tooth long shaft; locating an implant by using the tooth long shaft; adjusting the position and posture of the implant; extracting mesiodistal ortho-tooth half-crown data in the tooth missing region, and increasing the thickness uniformly; measuring the straight line-segment distance between the occlusal surface and the tail end of the implant body; generating a three-dimensional digital model of the planting guide plate; and designing the outer surface of the bone augmentation area after bone graft, increasing the thickness, and reserving a bone grafting material filling hole, thus completing designing and processing. According to the method provided by the invention, the mesiodistal position, the buccolingual position, the torque angle and the shaft inclination degree for oral implantation of the tooth implant can be accurately guided, the accurate bone augmentation operation is realized, the tooth planting risk is reduced, the implant amount and surface form of the allogenic bone augmentation material can be conveniently and accurately controlled, and thus the success rate of the tooth planting operation can be improved.

Description

technical field [0001] The invention relates to a method for designing and manufacturing a guide plate for dental implant surgery, in particular to a method for designing and manufacturing a guide plate for implant bone augmentation guided by restoration. 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...

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.
