A toothbrush handle includes a support structure formed of clarified polypropylene and a body formed of thermoplastic elastomer disposed on the support structure. The support structure includes a web having a thickness in a first direction orthogonal to an axis of the toothbrush handle of less than 2 millimeters and at least one rib depending from the web and having a thickness in a second direction, orthogonal to the axis and angled relative to the first direction, of less than about 2 millimeters. The body at least partially covers the web and the at least one rib. The handle has a light transmissivity of greater than 40% through a portion of the handle at which the body covers the web and the at least one rib.

An implant assembly device configured to press an inner femoral head into a plastic outer femoral head by means of actuator system. The actuator system embodies a unique pawl system that acts to reduce the occurrence and severity of device jamming due to over compression. The device includes a unique head support apparatus that aligns and orients the inner and outer femoral heads prior to and throughout the assembly process. The device can also include a grip portion integrated onto the body of the device, for holding and stabilizing the device when in use.

A cosmetic applicator assembly includes a handle body having a proximal end, a distal end, a largest width or diameter of from 0.4 inches to 1.25 inches, and an exterior surface, an elevated feature disposed along the exterior surface and extending from 0.007 inches to 0.020 inches above the exterior surface, and a cosmetic applicator coupled to the distal end of the handle body and constructed to apply a cosmetic. The handle body includes a handle body material. The elevated feature include an elevated feature material, wherein the elevated feature material has a kinetic coefficient of friction of greater than or equal to 0.55 and a hardness of less than or equal to Shore A 70, and a hardness that is less than the hardness of the handle body material.

An oral care implement has a front side and a back side opposite the front side and an overall length extension between mutually opposite proximal and distal ends. A head of the implement, disposed at the proximal end, has at least one cleaning element extending from the front side. A handle is at least partially made from a material having a density higher than that of the head's material. The handle's cross-sectional area, extending substantially perpendicular to the overall length extension, has a height extension between the front and back sides. The implement has a center of gravity situated below an axis of rotation when the oral care implement is placed with its back side on a surface. The center of gravity is closer to the back side than to the front side of the implement when measured along the height extension of the handle.

An oral care implement has an overall length extension extending between a proximal end and a distal end, the distal end being opposite the proximal end. The oral care implement comprises a head at the proximal end and a handle, the handle being at least partially made from a material having a density being higher than the density of the material of the head. The oral care implement has a center of gravity located at a distance measured from the distal end, and the ratio of said distance to the overall length extension of the oral care implement is from about 0.30 to about 0.45, preferably from about 0.35 to about 0.42, further preferably from about 0.38 to about 0.41.

A toothbrush including bristles extended from one end of the toothbrush, a handle extended from another end of the toothbrush opposite the one end, and any of an attachment hole, arranged between the bristles and handle and configured to receive a support leg to be attached therein, and a groove are provided, either of which may improve drying and therefore decrease in transmission of pathogens via the bristles by, for example, improving air circulation to the bristles raised away from a surface via action of the end and the surface.

An oral care system that includes an oral care implement and a tracking attachment. The oral care implement may include a handle and a head. The tracking attachment is detachably coupled to the oral care implement. The tracking attachment may include a first component comprising a first housing having an inner surface that defines a first cavity and a second component comprising a second housing having an inner surface that defines a second cavity. When the tracking attachment is coupled to the oral care implement, a first portion of the handle is positioned within the first cavity and a second portion of the handle is positioned within the second cavity.

A method for oral care. In one aspect, the method for oral care includes a) receiving sensor data from at least one sensor configured to detect motion of an oral care device during a brushing routine of a user, the sensor data corresponding to the detected motion; and b) determining a target brushing time based on the sensor data. In another aspect, the method for oral care includes a) receiving sensor data from at least one sensor configured to detect brushing intensity during a brushing routine of a user, the sensor data corresponding to the detected brushing intensity; and b) determining a target brushing time based on the sensor data.
