Description
Technical Field
The application belongs to the field of surgical instruments, and particularly relates to a guide plate for an oral implant operation.
Background
In order to improve the success rate of the oral implant treatment, the diameter and depth of the implant cavity are strictly matched with the size of the implant to be implanted in the operation, so that enough stability can be obtained in the early stage of implant implantation. The axial and position of implant should strictly meet the therapeutic design to meet the requirements of biomechanics and aesthetics.
The traditional method of forming planting holes involves using different types of mechanical drill bits to create planting holes of different diameters and depths. Mechanical drills generate high temperatures during operation, which may cause thermal damage to bone tissue. In order to reduce the heating of bone tissues, the mechanical drill is matched with sufficient low-temperature saline water for flushing and cooling. However, when the bone density is high, the cooling water is difficult to reach the osteotomy site, or the sharpness of the drill is reduced, high temperature may still be generated, resulting in bone tissue loss and even necrosis. In addition, the mechanical drill must apply a certain pressure to the bone tissue during operation, and it is difficult to preserve the weak bone tissue structure due to the vibration. Improper handling may also cause soft tissue damage due to the sharp nature of the mechanical drill. Mechanical drills are also difficult to maneuver in tight areas due to the drive requirements.
At present, the laser has the effects of minimally invasive, high efficiency, safety and the like when being used for osteotomy and has already been clinically approved. The laser output needs higher energy density, so the action range is extremely small, which is one of the prerequisites of accurate and minimally invasive laser osteotomy. However, in the oral implant operation, the laser is completely operated by hands, and the accurate-size cavity is difficult to obtain under the condition of lacking of guidance. The guide plate that the operation of present oral implantation used all designs to mechanical drill bit, can't be used for the laser operation.
