摘要: An ultrasound oral hygiene and therapeutic device comprises an array of ultrasonic transducers, a power generator, filling element. The transducer array, with optional radiation plates reflection plates, produce uniform on each surface desirable to be treated by radiation. soft resilient element snugly fits into user's cavity, confines cleaning solution the action within limited zone surrounding surfaces treated, protects all other parts cavity from provides superior, uniform, consistent results in short time. In particular, it cleans entire dental surface, including inter-dental gingival areas. It is extremely easy use, quiet, durable, energy efficient, inexpensive long run.
