With the increasing maturity of dental implant technology, oral function reconstruction using oral implants has become a routine treatment scheme. The ultrasonic osteotome converts electric energy into mechanical energy by using a high-intensity focused ultrasound technology and a transducer, and bone tissues to be cut are thoroughly destroyed by high-frequency ultrasonic oscillation. The ultrasonic wave is specific to bone tissues, and soft tissues cannot be damaged, so that anatomical structures such as mucous membranes, nerves, blood vessels and the like can be effectively protected; in addition, the ultrasonic osteotome has high cutting efficiency, accurate osteotomy and less bone loss, so that the ultrasonic osteotome is more and more widely applied to oral cavity related operations.
At present, a planting drill bit used clinically is matched with a planting mobile phone, and a special ultrasonic planting drill bit matched with an ultrasonic osteotome machine does not exist. The existing planting drill has the following problems: firstly, no bone cutting specificity exists, and the risk of damaging mucosal tissues and nerves exists; secondly, the cutting efficiency is not high enough, and the operation time is increased at the position where the bone is hard; and the most of the cooling modes are external cooling, and the sterile physiological saline is injected into the planting pit through a small hole at the head part of the mobile phone to flush out bone mud and chips in the pit. However, after the thickness of the bone exceeds 6mm below the bone, the external cooling may be insufficient, so that bone injury is caused, and the later period of bone union is influenced. If double cooling flushing is applied, an internal cooling water pipe and an external cooling water pipe are connected to the planting mobile phone at the same time, and a special internal cooling drill point is used, so that the planting mobile phone is complex.
The bone density is divided into four types, I type bones are hard bones, II and III types are common bones, IV type bones are loose bones, and bones with different densities are suitable for tool bits with different designs. The maxillary compact bone belongs to class I-II bones. Therefore, there is an urgent need to develop an ultrasonic implant drill suitable for maxillary compact bone, which is used for improving bone cutting efficiency, protecting important soft tissues such as nerve vessels and the like and reducing postoperative reaction.
