Description
The technical field is as follows:
the invention relates to the field of dentistry, in particular to a dental implant posterior tooth area implant guide plate and a manufacturing method thereof.
Background art:
the implant denture solves the problem of osseointegration between the implant and the alveolar bone of a human body through development of a half or more century, ensures the mechanical strength of the implant, improves the connection between a repair abutment and the implant day by day, becomes an important repair method for repairing dentition defects, has a stress mode similar to that of a natural tooth, is attractive and comfortable, and recovers the physiological functions of the mouth and jaw of a patient to the maximum extent. More and more patients take implant denture repairs as the first choice for their own missing tooth repairs.
The key of the successful implant denture repair lies in implanting the implant into the ideal position of the implant repair in the jawbone of the human body, and ensuring the success of the final repair. For the control of the implant site, firstly, by referring to the X-ray curved surface layer sheet, according to the specific conditions in the oral cavity, an operator selects the implant site and implants the prepared hole on the alveolar bone in a free hand mode, and implants are implanted. The control of the position and the direction of the free hand implanted into the implant is totally dependent on the experience and the hand feeling of an operator; most of the posterior dental sites in the mouth cannot be visualized directly, and deviations in vision often result in deviations in the implant site. With the development of the CBCT and the digital scanning technology, the digital half-way guide plate and the full-way guide plate are rapidly applied to clinical application, the accuracy of the fixed point and the implantation direction is obviously improved, but the digital guide plate is manufactured by either investing a large amount of capital to purchase digital equipment or expending extra expensive processing cost. Sometimes, the error in the manufacturing process may also cause the deviation of the planting direction. The digital navigation planting technology developed recently can perform real-time virtual visual planting operation, theoretically has higher precision, but the actual navigation equipment is more, and a planting mobile phone is added with more matching devices, so that the difficulty of clinical operation is enhanced. Some surgical risks are also introduced due to the lag in the navigation signal. Meanwhile, the operating space of the posterior dental area is narrow, the number of the digital planting guide plates and the planting navigation devices is large, and the digital planting guide plates and the planting navigation devices are difficult to normally implement in patients with small mouth opening degree or strong pharyngeal reflex. The digital planting technology is expensive in equipment, has more accessories and is not beneficial to popularization in primary hospitals.
The invention content is as follows:
the invention provides a posterior tooth implantation operation guide plate which is simple, convenient and feasible in clinic, low in price and guaranteed in certain precision, and aims to help an operator determine a correct implantation site and an implantation direction of an implant, correct intraoral visual errors of the operator and guarantee a final good implantation repair effect.
