Description

Be applied to improvement of cheekbone operation of planting and be equipped with hole and bore

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to an improvement that is applied to operation is planted to cheeks is equipped with hole and bores.

Background

The implant repair of a patient with maxillary dentition deficiency and serious insufficient residual bone mass is one of the problems to be solved urgently in the field of oral implant. When the residual bone amount of the upper jaw is seriously insufficient or a maxillary defect exists, the implementation of the traditional bone augmentation technology is difficult to obtain a predictable bone formation effect, and can greatly prolong the treatment period and increase the injury and the burden of a patient in the operation. The 1998 Branemark professor firstly proposes an implantation technique for implanting a longer implant into cheekbones to solve the problem of insufficient maxillary bone quantity, and reconstructs maxillary dentition with a one-stage fixed prosthesis by implanting one cheekbone implant into each side of the maxillary dentition and combining 2 to 4 conventional implants in the anterior dental area. The dense bone mass of the cheekbones and sufficient bone mass allow the implant to obtain sufficient initial stability after implantation, providing the necessary conditions for immediate repair. The toothless restoration also brings great challenges to clinicians, the implantation site of the implant needs to be reasonably designed on preoperative planning software, a temporary false tooth is made for a patient before the implantation, and CT data is led into the planning software to be fitted with preoperative CT, so that the method is the most accurate method for determining the penetrating position of the implant at present. For the patient with the seriously insufficient maxillary residual bone, the zygomatic bone implanting technology greatly shortens the treatment course, reduces the operation times, avoids a large amount of complex bone augmentation operations, and can carry out immediate repair to realize the requirement that the patient has teeth immediately. The zygomatic bone implantation case has the difficulties that the implantation operation path is long, the implantation position is adjacent to the orbit and contents, the infraorbital nerve vascular bundle, the zygomatic facial skin and the like, most of the operation area cannot be directly observed, the implantation path deviation is easy to occur, and various operation complications are caused.

For patients with serious insufficient residual bone mass in the anterior dental area and incapability of implanting conventional implants, the traditional surgical indication of zygomatic bone implantation is not met. Bothur et al teach the feasibility of implanting multiple implants into a single cheekbone, and implant 2 and 3 implants into each of the two cheekbones, respectively, and then propose an improved technique of implanting 2 cheekbones into each of the two cheekbones, also known as a double-cheekbone implant implantation. The improved operation type has wider adaptation diseases than the classical operation type, and can obtain more optimized stress distribution of the implant. However, studies indicate that when 2 implants are implanted into a single cheekbone, the implant is more likely to be positioned too close to injure important anatomical structures such as eyeballs and infraorbital nerve vessels, and serious surgical complications are caused. In order to improve the accuracy and safety of the zygomatic implant implantation operation, currently, there are clinical learners who use a computer-assisted surgery navigation technique to help complete the operation.

Referring to fig. 1, a prior art back hole drill is schematically used. When carrying out the zygomatic implantation operation, if the implanted path of the zygomatic implant is of the sinus type, the anterior lateral wall windowing operation of the maxillary sinus is needed in advance, the mucosa of the maxillary sinus is stripped and lifted to avoid the implanted path, and then instruments such as a prepared hole drill 11 of the zygomatic implant and the like reach the zygomatic bone through the cavity 12 in the maxillary sinus to carry out the prepared hole of the zygomatic implant and the implantation. The function of the pilot drill 11 is simply to prepare the cavity for the implantation of the zygomatic implant.

Referring to fig. 2, a schematic diagram of an embodiment of a prior art back hole drill is shown. The drill thread 211 of the hole drill 21 in the prior art is a twist drill thread and has a cutting edge, the length of the working area is the total length of the drill, the length L0 is about 35mm, and the rotary power is obtained by connecting the hole drill with a planting mobile phone.

Because the thread length of the drill bit of the prepared hole drill in the prior art is the full length of the drill, the adjacent mucosa of the maxillary sinus is very easy to be rolled in the prepared hole process of the cheek planting operation in the sinus, so that the perforation or rupture of the mucosa of the maxillary sinus and other operation complications exist, the risk of damaging other adjacent soft and hard tissues exists, and the operation wound is larger.

Therefore, it is particularly important to design a backup hole drill which can reduce unnecessary iatrogenic injuries in the zygomatic implantation surgery and increase the success rate of the zygomatic implantation surgery.
