Technical Field

The invention belongs to the technical field of medical appliances, and particularly relates to tooth implantation measurement guide forceps.

Background

After the loss of teeth, there are many restoration methods, and tooth implantation is becoming a mainstream choice. The basic principle of the tooth implantation technology is as follows: cutting off gum under local anesthesia, exposing alveolar bone in the edentulous area, preparing a cavity in the alveolar bone by using a high-speed drill while cooling by water injection, implanting a cylindrical artificial tooth root with threads into the cavity of the alveolar bone, connecting an abutment at the upper end of an implant after the implant is combined with the bone formation, and repairing the dental crown. It can be seen that the basis of dental implantation is that a sufficient amount of bone must be available, and the most critical factor determining success or failure of implantation is whether the implant can obtain sufficient bone support, and the implant must be wrapped with bone of a certain thickness on each side, otherwise implantation failure may result. However, after the tooth is lost, the alveolar bone is continuously absorbed, atrophied and reconstructed, the bone appearance becomes irregular, the individual difference is very large, and the understanding of the bone appearance structure of the alveolar ridge in the tooth-missing area is a precondition for tooth implantation and is a basis for selecting the thickness and length of an implant. In the process of tooth implantation, the directionality of drilling a bone prepared hole is crucial, if the direction is inclined and deviates from one side of an alveolar bone, one side of an implanted artificial tooth root is not wrapped by the bone, the implantation operation can fail, the more serious consequence is that the lingual side of a mandible often has a blood vessel shape closely attached to a bone wall, a drill deviates from the range of the mandible, the vascular injury of the mouth bottom can be caused, if the drill is not found and treated in time, the life of a patient can be endangered, if the implantation direction faces to the middle point of the inner side and the outer side of the sclerotin, and the inner side and the outer side of the implanted implant are wrapped by the sclerotin with the same thickness, the operation implantation is successful.

At present, the width and the height of a bone substance are measured on a CT three-dimensional image through oral CT examination, but how to correspond the measuring position on the CT digital image to the oral cavity of a patient in the process of operation is difficult to solve. The current best solution is to establish a digital model based on CT data, manufacture an individualized 3D printing implantation guide plate, and arrange a lantern ring for limiting the drilling direction on the guide plate, so that the direction of drilling the bone and preparing the hole in the implantation operation process is correct, and the success of the implantation operation is guaranteed to the maximum extent. However, the 3D printing implant guide plate is manufactured individually, and can be used only once for one patient, and cannot be used for other patients. The preparation cost is high, the treatment cost of tooth implantation is greatly increased, and the economic burden of a patient is also increased; the time of 1-2 weeks is usually needed for manufacturing the tooth planting operation guide plate, the tooth planting treatment period is further prolonged, the individualized tooth planting operation guide plate manufactured by current 3D printing is difficult to be widely applied, particularly in a basic oral clinic, many clinics even do not have machine equipment for shooting CT, CT cannot be shot, the height and the thickness of alveolar bones cannot be measured, the 3D printed planting guide plate is not needed to be manufactured, for the basic oral clinic which does not have CT shooting conditions, the planting operation is carried out under the condition that the bone conditions of patients are not known in advance, the operation difficulty is increased, the operation risk is increased, and the success rate cannot be guaranteed.
