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 a posterior tooth implantation tooth 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 surgery is a relatively simple surgical operation, and comprises the steps of selecting an implant bed on an alveolar bone, drilling a hole (spare hole) in the implant bed, and implanting an implant into the hole, wherein the prepared hole is a cavity hole, which is called a spare hole surgery for short. 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 operations 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 direction, the strength and the reaction force of the acting force, so that the long axis of the cavity has an included angle relative to the long axis of the adjacent tooth, namely the cavity is inclined, if the inclination 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, the loading direction of the tooth under stress and the loading channel of the implant form an included angle, the axial stress of the implant is uneven, 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 during stress, the possibility of the deviation of the implant exists after long-term use, and the long-term service life and the long-term effect of the implant are not facilitated. Therefore, the method and the related equipment capable of improving the accuracy of the dental implant preparation hole are urgently needed in the oral medicine clinic.

The teeth of the adult permanent dentition can be divided into anterior teeth and posterior teeth, the anterior teeth comprise three teeth on two sides of the middle line of the maxillofacial region of a person, the anterior teeth comprise incisors, lateral incisors and single cuspid teeth, the teeth after the fourth tooth (comprising the fourth tooth) are called posterior teeth, and the posterior teeth comprise first premolars, second premolars, first molars, second molars and third molars. From the physiological structure, the longitudinal-fit curves of the posterior teeth on two sides of a human are relatively identical, the heights of the same teeth on the two sides are basically identical, and the same teeth on the two sides have similarity in structure, such as the front and back positions, the heights, the buccal-lingual angles and the like of the first molar on the left side of the lower jaw and the first molar on the right side of the lower jaw, and the positions, the heights, the buccal-lingual angles and the like of the first premolar on the right side of the upper jaw and the first premolar on the left side of the upper jaw are similar, so that the positioning of the pit information on the side through the position information of the same teeth on the opposite side during the hole preparation implantation on the posterior teeth has high feasibility.
