Description

Technical Field

[0001] The utility model relates to the technical field of dental medical equipment, in particular to an implant positioning and tightening device. Background Art

[0002] In implant treatment, doctors often need to use a torque wrench to implant implants, tighten secondary components such as fixing screws and healing abutments; the torque wrench enables doctors to apply uniform torque and provide sufficient pre-tightening force when connecting the abutment and the implant, avoiding problems such as thread failure caused by excessive torque, and ensuring the correct positioning of the abutment, greatly reducing the working difficulty of doctors without damaging the implant.

[0003] Currently, the torque wrenches used in the dental industry are generally mechanical torque wrenches using a spring mechanism or deformable elastic metal components; the mechanical torque wrench has more components, and is small in size and precise, making disassembly and assembly more complex. Moreover, as a medical device, the dental torque wrench needs to be disinfected frequently, so it is necessary to frequently disassemble and assemble the torque wrench, increasing the difficulty of using the mechanical torque wrench; in addition, the mechanical torque wrench will also cause inaccurate torque due to various reasons such as assembly errors, component rust, and damage. Moreover, the wrench is assembled from multiple components, and blood stains will enter the internal parts of the wrench during use, and cleaning and maintenance need to be disassembled into multiple parts and cleaned and disinfected one by one, which is time-consuming and laborious; furthermore, implant positioning requires cutting the gum to install the healing abutment after waiting for bone integration after implanting the implant, so it is necessary to know the approximate position of the implant. The commonly used positioning method is to take an X-ray dental film, but the dental film is a two-dimensional image, which can only obtain the approximate position and cannot accurately know the specific position of the implant, bringing certain difficulties to the doctor's operation.
