Technical Field
The utility model relates to an oral cavity technical field, concretely relates to be arranged in preoperative edentulous district three-dimensional space measurement and art location survey device that checks.
Background
Because of the characteristics of high chewing function, good aesthetic effect, no damage to adjacent teeth and the like, the dental implant has become a hot point treatment scheme for patients with dentition defect and dentition deficiency. With the vigorous development of the oral implantation technology, a plurality of treatment technologies such as a free-hand implantation technology, a surgical guide plate technology, a digital three-dimensional navigation technology and the like are widely applied to clinic, and a scientific and reasonable treatment technology supports dental implantation to become a safe, stable and high-success-rate treatment scheme. Meanwhile, clinicians and scholars continuously perfect the planting and repairing concept in scientific exploration, and achieve the planting and repairing consensus of 'taking repairing as guidance'. The design of the three-dimensional site for implantation is guided by simulating the space position of the target prosthesis, so that implantation complications such as neural tube injury, adjacent tooth injury and the like can be effectively prevented. Research shows that incorrect implantation and restoration concepts, poor restoration space design, poor three-dimensional implant sites and the like are important reasons for implant failure. The analysis of the intraoral space before the operation is also a key link as a basic link of the design before the planting operation, and is important for avoiding the complications generated by the factors. Therefore, in order to improve the precision of the implant surgery and avoid the complications of the implant surgery, it is necessary to perform intraoral and model space analysis before the surgery by using a quantifiable measuring device.
Most clinicians currently perform intraoral analysis by visual inspection or simple measuring devices. Visual methods depend extremely on the individual clinical experience of doctors, lack of quantitative data records, and are prone to memory bias and vision errors. The simple measuring device measurement method mainly refers to a method for performing intraoral space analysis by using a common periodontal probe equivalent measuring device, and because the simple device lacks personalized parameter setting, a clinician is often required to perform secondary processing of data after measurement, and the significance of design guidance before planting is insufficient; the scale indication of the simple measuring device is not easy to identify under the condition of insufficient back tooth area or opening degree, so that a clinician is easily influenced by angle and sight line factors to cause measuring errors.
Meanwhile, the surgical guide plate is not suitable for people due to the limitation of factors such as the opening degree of a surgical area and economic capability in the surgical process, and the bare-handed planting under naked eyes lacks reference and guidance
In conclusion, the three-dimensional space analysis of the current edentulous area depends on clinical experience, an accurate and efficient auxiliary measuring device is lacked, and an effective device for transferring preoperative analysis to the mouth is lacked during bare-handed planting.
