Description

Implant mobile phone, guide assembly and method for drilling implant hole on dental bed

Technical Field

The invention relates to the field of dental implantation, in particular to an implanting mobile phone, a guiding assembly and a method for drilling an implant hole on a dental bed.

Background

Digital implant technology or image-guided dental implant surgery is performed by modeling the data of a patient's CT and/or dental model, simulating the placement of an implant, and then designing and manufacturing an implant guide. The implant guide plate is a personalized surgical tool covering a gum and a gum, and is provided with a guide hole for guiding an implant drill to drill the gum and control the depth and direction of the drill hole. Since the implant guide is externally arranged on the gum, the sum of the height of the guide hole and the thickness of the gum is called as "extension amount". Therefore, the drill bit also needs to be extended appropriately, ranging from 7-11mm, with most extensions being 9 mm.

The existing drill point with the lengthened structure mainly comprises two types: one is that the whole body of the drill point has a single diameter (divided into a drill bit part at the lower part and a guide cylindrical part at the upper part), and an adaptive part, which is generally called a pressure plate or a handle, is needed to match the diameter of a guide hole on the planting guide plate; another is that the upper guide cylinder of the drill bit is of uniform diameter (so as to fit directly into the guide bore) and the lower drill bit portion is of different diameter. Both of these configurations have a stop top configuration, commonly referred to as a "stop", which is configured in a flanged pattern having a larger diameter than the pilot hole. The drill points of the above two elongated structures are generally called planting navigation drills.

The planting navigation drill of each manufacturer is not universal (because the diameters of the plants of each manufacturer are different, guide holes with different diameters need to be matched, and the shapes and the tapers of the plants of each manufacturer are not consistent and need to be matched with corresponding reamers). And for each implant a correspondingly lengthened version of all sizes of drill pins is required, which requires a large number of different types of drill pins.

Longer drill pins are sometimes difficult to adapt to the patient's mouth, especially in the molar area. Also, since the implant has a taper angle, the corresponding drill bit also has a taper angle. The extended drill bit used must have the same taper angle as a conventional drill bit. When different manufacturers have different taper designs for drill bits, one must use a set of drill bits for a set of implant designs. It is difficult and impractical for the dentist to perform pilot surgery with different brands of implants.

Furthermore, the dentist will change the length of the implant during the operation as desired, and when the dentist wants to change the implant length, the total drill hole length, the drill point length and the extension value all need to be checked, which is very complicated for the dentist's actual operation, let alone in a clinical environment.
