Description
Technical Field
The invention belongs to the field of medical appliances, and particularly relates to a working tip special for maintaining an anterior tooth implant.
Background
The principle of the implant is that a pure titanium metal dental implant with high compatibility with human bone is implanted into an alveolar bone of a tooth-missing area in a medical mode, bone combination is generated after 1-3 months, and then a porcelain dental crown is manufactured on a base station. Because of no damage to adjacent teeth, dental implants have been recognized by the oral medical community as the preferred way to repair missing teeth.
After the implant is implanted into the tooth-missing area, bacteria, toxins and the like have biological damage to the joint of the gingiva and the implant, and mechanical damage when the implant is stressed can indirectly influence the service life of the implant. The implant is maintained regularly to avoid inflammation and mucous membrane diseases in the oral cavity.
The ultrasonic tooth cleaner is a common medical instrument in the field of dentistry, and can be used for scraping stones and dental plaque on the surface of teeth, preparing dental cavities, treating root canal of teeth and the like. An ultrasonic transducer is arranged on the ultrasonic tooth cleaner and is used as an ultrasonic oscillation source, and the electric energy is converted into ultrasonic oscillation to drive a working tip arranged on the transducer to work. After the working tip of the ultrasonic vibration tooth cleaner contacts with the tooth surface, the functions of scraping stones on the tooth surface and the like of the ultrasonic tooth cleaner can be realized.
Most of the existing tips are linear tips, which are easy to destroy the crown surface of the implant, and it is difficult to achieve a narrowed region and a recessed region between the implant and the teeth through an interproximal region between the teeth.
