摘要： Powered toothbrush systems that provide improved bristle positioning and bristle contact with tooth surfaces that reduce the time and effort required for effective brushing. Some embodiments use alternating or oscillating pneumatic pressure and suction to move a toothbrush head. Various configuration of the brush head provide different areas of coverage ranging from individual tooth to quarter mouth (U-cross section), to half (U-cross section or H-cross section) or whole mouth (U-cross section or H-cross section) coverage. Some embodiments include flexible fingers and/or bladders to keep the bristle tips properly engaged with the teeth and gums, providing bristle contact over a wide variety of malocclusion. The shape of the brush heads adapts to conform closely to the shape of the user's dental tray and to any malocclusion that may be present. The powered toothbrush automatically generates motion of the brush head that simulates the Modified Bass Method of brushing.

摘要翻译：动力牙刷系统提供改进的刷毛定位和与牙齿表面的刷毛接触，减少有效刷牙所需的时间和精力。一些实施例使用交替或振荡的气动压力和抽吸来移动牙刷头。刷头的各种配置提供从单个牙齿到四分之一口（U形横截面）到一半（U形横截面或H截面）或全口（U形横截面或H交叉）的不同覆盖范围部分）覆盖。一些实施例包括柔性指状物和/或囊以保持刷毛尖端与牙齿和牙龈正确接合，从而提供各种错牙合的刷毛接触。刷头的形状适应于与使用者的牙弓的形状和任何可能存在的咬合错合。动力牙刷自动生成刷头的运动，模拟“刷新”的“改良低音方法”。
