Description

Zygomatic bone planting ultrasonic prepared hole drill set

Technical Field

The application relates to the technical field of medical equipment, in particular to a zygomatic bone implantation ultrasonic prepared hole drill set.

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 technology for implanting a longer implant into cheekbones to solve the problem of insufficient maxillary bone quantity, and reconstructs maxillary dentition by a one-stage fixed restoration body 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.

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, the zygomatic implantation surgical technique has long implantation surgical path, the implantation position is adjacent to the orbit and the content, the infraorbital neurovascular bundle, the zygomatic facial skin and the like, most of the surgery areas can not be directly viewed, the implantation path deviation is easy to occur, and various surgical complications are caused. The thread of the zygomatic implant hole preparation drill is in a twist shape and has a cutting edge, so that the adjacent maxillary sinus mucosa is very easy to be rolled in the hole preparation process of the sinus internal zygomatic implant operation, thereby causing operation complications such as perforation or rupture of the maxillary sinus mucosa and the like, and also having the risk of damaging other adjacent soft and hard tissues. In addition, cheekbones are compact sclerotin of human body, and the problem that the cheekbone implant drill is not cooled in place easily during deep work is solved.

Therefore, there is a need to improve the design of zygomatic implant pilot hole drills to effectively prevent the above surgical complications.
