Recently, research on bone fracture and osteoplasty using ultrasonic bone surgery unit has been ongoing in the fields of dentistry, plastic surgery, and otorhinolaryngology. However, detailed data evaluation with ultrasonic bone surgery unit has not been conducted to date. In this study, we developed handpiece moving system (HMS) for cutting performance evaluation. In the experimental setup of HMS, a handpiece was immobilized, and bone samples from cortical bone of bovine leg were prepared. Also, the experimental process was described in detail, and a basic experiment was carried out to evaluate the cutting performance. Future study is required on all experimental process conditions by HMS.

While dental clinics still use the ultrasonic scaling/surgery tool for teeth scaling and cleaning the tool's use is expanding steadily to include treatment of damaged teeth and bone tissue. In this study, a handpiece moving system (HMS) was developed to evaluate bone scaling and cutting in the field of dentistry. The HMS, through a scaling test of bone using a scaler tip, it was able to identify surface damage. Additionally, a thermos-graphic camera was used to observe the temperature distribution that occurred during the bone scaling and cutting process. Consequently, we found that increasing the working load increased the amount of surface damage. Changes in temperature distribution occurred slowly and were maintained within safety bounds for 10 minutes. Going forward, we will compare the HMS performance on scaling and cutting with other devices.

In the dentistry field, an ultrasonic surgery unit is widely used in bone cutting and scaling to reduce operation time and minimize hemorrhage. The purpose of this study was to evaluate bone cutting and the effect of a specimen's temperature on the two-type ultrasonic surgery unit using a handpiece moving system(HMS). A HMS, which can cut the bone, was developed to perform the experimental procedure with precision of motion control. Bone specimens were prepared from a combination of epoxy-hardener and cortical bone of bovine leg. Through the bone-cutting experiment, the cutting depth was evaluated by not only scanning electron microscopy, but also Vernier calipers. Also, the temperature distribution was measured by a thermo-graphic camera. This study may be applied methodically in various experimental evaluations on a performance test by a HMS.

치과 분야에서 초음파를 이용한 수술기 및 스케일러의 사용은 꾸준하게 증가하고 있다. 이때 개발된 기기의 성능 및 안정성은 시술 받는 환자에게 결정적인 요소로 작용하기 때문에 상업화 전에 반드시 시험 평가되어야 한다. 그래서 골 절단 및 치아 스케일링 평가를 수행할 수 있는 핸드피스 이송 시스템을 자체 개발하여 사용하였다. 본 연구의 목표는 초음파 스케일러 팁을 이용하여 치아 손상 정도를 평가하기 위함이다. 추가적으로 초음파 기기의 열 발생 및 소음에 대한 측정을 수행해보았다. 결과적으로 Ultrasonic NX 기기의 높은 출력은 실험을 통한 치아에 심각한 손상을 입힐 수 있지만 열 화상 카메라를 이용한 열 발생 및 소음 측정을 통해 안정적인 범위에 있었다.
