An oral care implement that rotates about a longitudinal axis. In one aspect, the invention can be an oral care implement comprising: a head a handle extending along a longitudinal axis and having a flat base surface a mechanical vibratory device operatively connected to a power source, the mechanical vibratory device comprising an eccentric imparting movement to the head when activated and wherein the flat base surface is oriented relative to the longitudinal axis of the handle so that the oral care implement can stand in a self-supporting upright orientation on a horizontal flat surface, and wherein when the oral care implement stands in the self-supporting upright orientation and mechanical vibratory device is activated, the oral care implement rotates about the longitudinal axis while maintaining the self-supporting upright orientation.本發明係揭露一繞一縱向軸線旋轉之口腔保健器具。一態樣中,本發明可為一口腔保健器具,包含:一頭;一握柄,其沿著一縱向軸線延伸且具有一平坦基底表面;一機械振動裝置,其操作性連接至一動力供源,該機械振動裝置包含一偏心件,其當啟動時傳遞運動至頭部;且其中平坦基底表面相對於握柄的縱向軸線被定向以使口腔保健器具可以一自我支撐直立定向站立在一水平平坦表面上,且其中當口腔保健器具以自我支撐直立定向站立且機械振動裝置被啟動時,口腔保健器具係繞縱向軸線旋轉同時維持自我支撐直立定向。100‧‧‧牙刷110‧‧‧握柄115‧‧‧頸部126‧‧‧握柄110的內表面130‧‧‧頭部135‧‧‧牙齒清潔元件141‧‧‧長形握持部分142‧‧‧基底部分151‧‧‧“開通”鈕152‧‧‧“關斷”鈕160‧‧‧開關161‧‧‧開關160的第一端162‧‧‧開關160的第二端170‧‧‧機械振動裝置171,180‧‧‧腔穴172,173‧‧‧電引導線174‧‧‧切換接觸部190‧‧‧電力供源191‧‧‧正極192‧‧‧負極
