A dental implant-abutment interface and assembly comprising an implant, an abutment removably attachable to the implant, and a screw receivable within an axial threaded bore common to both the implant and abutment. The implant includes an elongate body having a proximal end and a distal end, the axial threaded bore open at the proximal end, a radial end surface of a collar comprising the proximal end, and a plurality of axially elongate recesses substantially arcuate in radial cross-section, disposed polarly at the proximal end, and extending distally away from the radial end surface. Each of the arcuate recesses exhibit a curved wall, each having a tangent lying on a common circle disposed inwardly of a circumference of the collar of the implant. The abutment includes the axial threaded bore, a proximal end, and a distal end itself including a collar and prongs projecting distally away from a radial plane at a distal-most axial extent of the collar in which the radial plane is complementally engagable with the radial end surface of the implant. The prongs are disposed equipolarly about the axial bore of the abutment, and each of the prongs are proportioned for engagement with a respective one of the axial recesses of the implant, the axial bore of the abutment communicating with the axial bore of the implant, and the radial surface of the collar having a like radius to that of the radial end surface of the implant. Each of the prongs has a radial cross-section of lesser area than that of its respective implant recess.

The system of claim 4, wherein the first material comprises fluoride, and the second material comprises at least one selected from gingivitis treatments, whitening agents, breath treatments, and combinations thereof. 10. The system of claim 1, further comprising: (e) a third material reservoir for supplying a third material, wherein the third reservoir is in liquid communication with applicator, and wherein the third reservoir is supported by the body; and (f) a third material positioned in the third reservoir, wherein the third material comprises at least one selected from the group consisting of whitening agents, advanced cleaning agents, baking soda, peroxide, tartar control, and combinations thereof. 11. The system of claim 10, further comprising: (g) a fourth material reservoir for supplying a fourth material, wherein the third reservoir is in liquid communication with applicator, and wherein the third reservoir is supported by the body; and (h) a fourth material positioned in the fourth reservoir, wherein the fourth material comprises at least one selected from the group consisting of whitening agents, advanced cleaning agents, baking soda, peroxide, tartar control, and combinations thereof. 12. A toothbrush comprising: (a) a body; (b) at least one material reservoir supported by the body, wherein the at least one material reservoir comprises at least one treatment regimen of at least two materials disposed therein, and wherein the at least two materials are positioned to sequentially dispense from the reservoir; (c) an applicator supported by the body, and in continuous liquid communication with the at least one material reservoir; and, wherein a first material of the at least two materials comprises a whitening agent and a second material of the at least two materials comprises a polisher. 13. The system of claim 12, further comprising: (d) N number of treatment regimens positioned in the material reservoir, wherein each regimen is positioned to allow dispensing of substantially all of the first material of the Nth regimen prior to application of the second material of the Nth regimen, and positioned to allow dispensing of substantially all of the second material of the (N-1)th regimen prior to application of the first material of the Nth regimen, and wherein N is an integer of at least 1. 14. The system of claim 13 wherein each regimen further comprises a third material, wherein each regimen is positioned to allow dispensing of substantially all of the first material of the (N-1)th regimen prior to application of the second and third materials of the Nth regimen, and to allow dispensing of substantially all of the second material of the (N-11)th regimen prior to application of the third material of the (N-1)th regimen, and positioned to allow dispensing of substantially all of the third material of the Nth regimen prior to application of the first material of the Nth regimen, and wherein N is an integer of at least 1. 15. The system of claim 13, wherein N is 1. 16. The toothbrush of claim 12 wherein the at least one treatment regimen of at least two materials comprises a first material and a second material wherein the first material is a cleaner and the second material is a breath conditioning agent. 17. The toothbrush of claim 12 wherein the at least one treatment regimen of at least two materials comprises a first material, a second material, and a third material, and wherein the first material is a cleaner, the second material is a medicine, and the third material is a breath freshening agent. 18. A method of brushing teeth with a brushing system, wherein the brushing system comprises a body, first and second material reservoirs supported by the body, an applicator supported by the body, wherein the applicator is in continuous liquid communication with the first rese
