Abstract: An oral care refill head and an oral care kit comprising the same. The oral care refill head may include a sleeve portion, a head portion, and an elastomeric prophy cup. The sleeve portion may have an inner surface that defines an internal cavity for receiving a portion of a stem of an oral care implement handle therein so that the oral care refill head can be repetitively attached to and detached from the oral care implement handle. The elastomeric prophy cup may comprise an outer surface that forms at least a portion of a peripheral side surface of the head portion. The elastomeric prophy cup may be formed by injection molding an elastomeric material onto a support portion of the head portion. The oral care refill head may be packaged together with a store of an anti-sensitivity oral care material to form a kit.

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 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 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.
