Abstract: An oral care implement handle or a refill head therefor. The refill head may include a sleeve portion extending from a proximal end to a distal end, the sleeve portion having an inner surface that defines an internal cavity. The internal cavity may extend along a sleeve axis from an open bottom end at the proximal end of the sleeve portion to a closed top end, the internal cavity being configured to receive an attachment portion of a stem of an oral care implement handle. The internal cavity may have a proximal section adjacent the open bottom end and a distal section adjacent the closed top end. The distal section of the internal cavity may include a central portion located on the sleeve axis and at least one slot portion radially extending from the central portion.

Abstract: An oral care implement including a handle and a replacement head that is detachably coupled to the handle. The oral care implement may include a handle having a longitudinal axis that includes a gripping portion and a stem extending from the gripping portion. The gripping portion may have a shoulder that circumferentially surrounds the stem and an annular rib protruding from the shoulder. The replacement head may have a sleeve portion terminating in a proximal edge that is formed from a resilient material. The replacement head may be detachably coupled to the handle so that the annular rib of the shoulder and the proximal edge of the sleeve portion that is formed of elastomeric material are in contact with one another.

Abstract: An oral care implement handle or a refill head therefor. The oral care implement handle may include a gripping portion and a stem protruding from a shoulder of the gripping portion. The stem may include a post located at a distal end of the stem. The post may have a non-circular transverse profile. More specifically, the post may include a hub portion and a protuberance that either protrudes radially from a side surface of the hub portion, protrudes upward from the shoulder of the gripping portion, or both. The refill head may include a sleeve having an inner surface that defines an internal cavity. The internal cavity may include a central portion and at least one slot portion extending radially from the central portion. Thus, the internal cavity of the sleeve portion may have a profile configured to receive the stem of the oral care implement handle.

Abstract: A dental tray may include: a facial wall conforming to a facial dental arch of a wearer and having first and second ends; a first clip element coupled to and extending from the first end and configured to apply a first lateral pressure on a wearer's first tooth when it is inserted into the first clip; and a second clip element coupled to and extending from the second end and configured to apply a second lateral pressure on a wearer's second tooth when it is inserted into the second clip; wherein the front wall is formed of a first material having a first hardness, and each clip element is formed of a second material having a second hardness, the second hardness being greater than the first hardness.

Abstract: An oral care implement including a handle and a replacement head that is detachably coupled to the handle. The handle may include a gripping portion extending from a proximal end to a distal end and a stem extending from the distal end of the gripping portion. The stem may have an inner cavity. A vibratory element including a motor and an eccentric may be partially located in the stem. The eccentric may have a first end that is operably coupled to the motor and a second end opposite the first end, the second end having an aperture therein. A guide pin may be fixed to the stem such that a first portion of the guide pin protrudes into the inner cavity of the stem. The first portion of the guide pin may extend through the aperture in the second end of the eccentric.

Abstract: An oral care implement including a handle and a replacement head that is detachably coupled to the handle. The replacement head may include a head portion and a sleeve portion. The head portion may have a front surface with tooth cleaning elements extending therefrom. The sleeve portion may have a cavity configured to receive a stem of the handle and a proximal edge defining an opening into the cavity. Furthermore, the sleeve portion may be formed from a first component formed of a rigid material and a second component formed of a resilient material. The first component of the sleeve portion may include a locking element that is configured to mate with a locking feature of the stem to couple the replacement head to the handle. A portion of the second component may cover the locking element so that no portion of the locking element is exposed.

Abstract: 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.

Abstract: An oral care implement having an arrangement of tooth cleaning elements thereon. The oral care implement may include a head extending from a proximal end to a distal end and comprising first and second peripheral sides. A plurality of tooth cleaning elements extend from the head and are arranged in groups including a first peripheral grouping of tooth cleaning elements positioned adjacent the first peripheral side of the head and having first and second types of tooth cleaning elements, a distal grouping of tooth cleaning elements positioned adjacent the distal end of the head and having a third type of tooth cleaning element, and a proximal grouping of tooth cleaning elements positioned adjacent the proximal end of the head and having the third type of tooth cleaning element. The first, second, and third types of tooth cleaning elements are different in at least one more structural characteristics.

Abstract: An oral care implement and a refill head therefor. The refill head may include a sleeve portion and a head portion, a passageway extending through the head portion from a rear surface of the head portion to a front surface of the head portion, a plurality of bristle tufts mounted to the head portion and extending from the front surface of the head portion, and an integrally-formed monolithic mass of an elastomeric material comprising: (1) an elastomeric pad portion located on the rear surface of the head portion; (2) an elastomeric tooth contact element extending from the front surface of the head portion; and (3) an elastomeric anchor portion in the passageway connecting the elastomeric tooth contact element and the elastomeric pad portion.

Abstract: An electric toothbrush apparatus including an electric toothbrush handle and a cap coupled thereto for protecting tooth cleaning elements and a user actuatable switch. The electric toothbrush apparatus includes an electric toothbrush handle extending along a handle axis. The electric toothbrush handle comprises a handle portion comprising user actuatable input means, a power source, and a motion inducing assembly. A cap is detachably coupled to the electric toothbrush handle. The cap comprises a tubular sidewall forming a cavity about a cap axis and a protective member axially extending from a bottom edge of the tubular sidewall in a cantilevered manner so as to overly the user actuatable input means to prevent accidental actuation thereof.
