Technical Field

The invention belongs to the field of tooth implantation machine accessories, and relates to an operation auxiliary instrument for guiding a tooth implantation mobile phone to accurately position a drill bit on an alveolar bone during anterior tooth implantation preparation hole operation.

Background

The dental implant is a tooth missing restoration method which is based on a lower structure implanted into bone tissue to support and retain an upper dental prosthesis. It comprises a lower supporting implant and an upper dental prosthesis. It adopts artificial material (such as metal, ceramic, etc.) to make implant (generally similar to tooth root form), and adopts the operation method to implant into tissue (generally upper and lower jaws) and obtain firm retention support of bone tissue, and utilizes special device and mode to connect and support the dental prosthesis of upper portion. The implant can obtain the repairing effect which is very similar to the function, the structure and the beautiful effect of the natural tooth, and becomes the first-choice repairing mode of more and more patients with tooth deficiency. The dental implant operation is a simpler surgical operation, the process is to select an implant bed on an alveolar bone, drill a hole (spare hole) on the implant bed, the prepared hole is a cavity, the operation is called a spare hole operation for short, and then implant an implant in the cavity. The hole preparation operation of the implant is carried out by using an implanter, when the implant is used, a doctor holds an implanting mobile phone by hand to control the operation of instruments such as a pioneer drill, a twist drill, a reamer drill, a screw tap and the like, and the long axis of the cavity is ideally parallel to the long axis of the adjacent tooth (the long axis of the tooth is taken from the direction from the dental crown to the dental root of the tooth), so that the implant and the adjacent tooth are arranged in order, and the manufactured upper prosthesis is also in order. However, the operation process is carried out by the bare-handed doctor, and the deviation of the turning angle of the drill and the predicted angle inevitably occurs under the influence of the acting force direction, the strength and the reacting force, so that the long axis of the cavity forms an included angle relative to the long axis of the tooth of the adjacent tooth, namely the cavity inclines. If the inclination of the cavity is smaller, the angle foundation pile can be adopted for correction, the effect is not influenced, if the inclination is larger than 15 degrees, the manufacturing difficulty of the upper prosthesis is increased, the volume and the weight of the manufactured foundation pile and the upper prosthesis are correspondingly increased, in addition, an included angle is formed between the load direction of the tooth when the tooth is stressed and the loading channel of the implant, the axial stress of the implant is not uniform, the stress direction deviates to one side for a long time, the stimulation of the implant to the alveolar bone deviates to the inclined side when the tooth is stressed, the possibility of the deviation of the implant exists in long-term use, and the long-term service life and the long-term effect of the implant are not facilitated. There is therefore a need in the clinical practice of dentistry for a method and associated equipment that will improve the accuracy of cavity preparation procedures for dental implants.

The teeth of adult permanent dentition can be divided into anterior teeth and posterior teeth, wherein the anterior teeth comprise three teeth on two sides of the midline of the human maxillofacial region, including incisors, lateral incisors, single cuspid teeth, and the rest are posterior teeth. From the physiological structure, the direction deflection of the anterior teeth and the posterior teeth is large, the anterior teeth are transversely arranged, the posterior teeth are longitudinally arranged, and how to control the angle and the positioning of a drill bit by means of an intraoral fixed point in the anterior prepared cavity surgery and the posterior prepared cavity surgery is a difficult problem to solve.
