For example, according to practical experience, clinically, patients with an opening degree of an operation area smaller than 33mm are not suitable for an implantation operation because the implantation mobile phone cannot stand after being screwed into the drill point; patients with the opening degree of the operation area being more than or equal to 33mm and less than 43mm can be directly planted without the use of an implant guide plate; the opening degree of the operation area is larger than 43mm, and the guide plate can guide the descending high-precision implantation operation. Therefore, the opening degree of the operation area determines the operation mode of the patient and is a key factor to be considered in the design of the implant operation.
At present, the clinical solution to this problem is to actually measure the opening of the operation area by using a measuring ruler before the operation, but the measuring ruler has a very different shape from the actual used mobile phone and drill point, and cannot simulate the actual placement of the mobile phone and drill point in the operation, so that the measurement is not accurate, and the measuring ruler is easily blocked by the adjacent teeth and the jaw teeth in practice due to the special narrow space of the oral cavity, which further causes a large measurement deviation.
