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. ## Claims ### Claim 1 A powered oral care implement comprising: an upper outer casing comprising an upper cavity having an open bottom end, the upper outer casing defining an upper gripping portion of the powered oral care implement; an electronics assembly mounted to the upper outer casing and at least partially positioned within the upper cavity; a tracking module comprising: a lower outer casing detachably coupled to the upper outer casing to enclose the open bottom end of the upper cavity and define a lower gripping portion of the powered oral care implement; and a tracking unit integrated into the lower outer casing and configured to facilitate tracking at least one of a position, orientation, or movement of the powered oral care implement within an oral cavity of a user; wherein the tracking unit comprises a plurality of visual markers protruding from an outer surface of the lower outer casing. ### Claim 2 (depends on 1) The powered oral care implement according to claim 1 further comprising: a handle comprising the upper outer casing, the tracking module, and a stem extending from a top end of the upper outer casing; and a replacement head comprising a sleeve portion having a cavity, the replacement head detachably coupled to the handle with the stem located within the cavity of the sleeve portion. ### Claim 3 (depends on 1) The powered oral care implement according to claim 1 wherein the lower outer casing is formed from a rigid material and each of the plurality of visual markers is formed from a resilient material. ### Claim 4 (depends on 1) The powered oral care implement according to claim 1 wherein the lower outer casing comprises a plurality of holes extending therethrough, and wherein each of the plurality of visual markers is coupled to the lower outer casing within one of the plurality of holes. ### Claim 5 (depends on 1) The powered oral care implement according to claim 1 wherein the lower outer casing comprises a first part and a second part that are detachably coupled together, and wherein the tracking unit is integrated into the second part of the lower outer casing. ### Claim 6 (depends on 1) The powered oral care implement according to claim 1 wherein the lower outer casing comprises a cylindrical portion and a bulbous portion, the cylindrical portion being adjacent to the upper outer casing. ### Claim 7 (depends on 1) The powered oral care implement according to claim 1 wherein an outer surface of the upper and lower gripping portions is flush at an interface of the upper and lower outer casings. ### Claim 8 (depends on 1) The powered oral care implement according to claim 1 wherein the upper outer casing comprises a first connection element and the lower outer casing comprises a second connection element that mates with the first connection element to detachably couple the upper and lower outer casings together. ### Claim 9 (depends on 1) The powered oral care implement according to claim 1 wherein the lower outer casing comprises a lower cavity having an open top end, and wherein a first portion of the electronics assembly is positioned in the upper cavity and a second portion of the electronics assembly protrudes from the open bottom end of the upper cavity and is positioned in the lower cavity. ### Claim 10 (depends on 1) The powered oral care implement according to claim 1 wherein the electronics assembly comprises a power source, a motor operably coupled to the power source, and an eccentric operably coupled to the motor, wherein when the motor is activated the eccentric rotates to vibrate a head portion of the powered oral care implement, wherein the upper outer casing comprises an actuator for activating the motor. ### Claim 11 (depends on 1) The powered oral care implement according to claim 1 wherein the coupling of the upper and lower outer casings forms a hermetic seal that prevents the ingress of liquid into the upper cavity at an interface of the upper and lower outer casings. ### Claim 12 A powered oral care implement system comprising: an upper outer casing comprising an upper cavity having an open bottom end, the upper outer casing defining an upper gripping portion of the powered oral care implement; an electronics assembly mounted to the upper outer casing and positioned within the upper cavity; a first lower outer casing; a tracking module comprising: a second lower outer casing; and a tracking unit integrated into the second lower outer casing and configured to facilitate tracking at least one of a position, orientation, or movement of the powered oral care implement within an oral cavity of a user; and wherein the first and second lower outer casings can be interchangeably detachably coupled to the upper outer casing to enclose the open bottom end of the upper cavity and define a lower gripping portion of the powered oral care implement; and wherein the tracking unit comprises a plurality of visual markers protruding from an outer surface of the second lower outer casing.
