Description

Technical Field

[0001] The utility model relates to the technical field of dental drill equipment, in particular to a dental drill equipment for verifying implantation torque. Background Art

[0002] When implanting an implant, you need to drill a hole with a dental drill first, and then drill the implant into the bone at a certain speed. During the implant implantation process, verifying the torque is crucial for the dental drill equipment. The appropriate torque can ensure the safety of the implantation process. If the torque is too large, the bone may be damaged or the implant may not be properly installed. On the contrary, if the torque is too small, the implant may not be firmly fixed in the bone, affecting the stability of the implant. Appropriate torque helps promote the integration of the implant with the surrounding bone. Bones require a certain degree of pressure and stimulation to stimulate the growth of bone cells, thereby promoting bone integration and making the implant more firmly integrated into the patient's oral structure. By verifying the torque, the doctor can better control the surgical process. This helps to ensure the correct position, angle and depth of the implant, thereby maximizing the success rate of the operation. Appropriate torque also helps to reduce surgical risks and avoid potential complications. Appropriate torque can reduce the discomfort of the operation to the patient. Excessive torque may cause severe pain during surgery, while too little torque may require a longer operation, increasing the patient's discomfort and the time-consuming operation. Appropriate torque helps to reduce the recovery time after surgery. The correct implantation process can reduce postoperative complications, accelerate wound healing, and shorten the patient's recovery time.

[0003] Patent No. CN2011100646373 discloses a torque detector, which includes a torque input component, a torque display component, a torque detection component and a frame for fixing the aforementioned components, wherein the torque detection component includes: a driving force arm, which is coaxially sleeved with the torque input component and rotates integrally with the torque input component; and a torque conversion test cylinder, which is connected to the driving force arm and the torque display component respectively, and the driving force arm inputs its angular displacement to the torque conversion test cylinder, which is converted by the torque conversion test cylinder and outputs a displacement value to the torque display component to display the torque detection value.
