1. A set of mandibular repositioning devices for a patient, comprising:
at least one upper splint, each upper splint comprising a respective imprint of an upper dentition of the patient configured to fit onto the upper dentition and at least one upper fin affixed to the upper splint located at an unchangeable first distance (UD) from a posterior end of the upper splint;
at least one lower splint, each lower splint comprising a respective imprint of a lower dentition of the patient configured to fit onto the lower dentition and at least one lower fin located at an unchangeable first distance (LD) from a posterior end of the lower splint;
wherein the total number of upper splint(s) plus the total number of lower splint(s) is at least three, and further wherein the set of mandibular repositioning devices comprises two:
(i) upper splints, which each upper splint has the first distance (UD) being different from that of the other, resulting in a different mandibular repositioning offset when the upper and the lower splints are fitted onto the upper and lower dentitions, respectively, to generate a first mandibular repositioning and a second mandibular repositioning, respectively, or
(ii) lower splints, which each lower splint has the first distance (LD) being different from that of the other, resulting in a different mandibular repositioning offset when the upper and the lower splints are fitted onto the upper and lower dentitions, respectively, to generate a first mandibular repositioning and a second mandibular repositioning, respectively;
wherein the at least one upper fin comprises an upper fin front surface and the at least one lower fin comprises a lower fin back surface, such that when the at least one upper splint and the at least one lower splint are worn by the patient at the same time, the front surface of the at least one upper fin contacts the back surface of the at least one lower fin, thereby causing a defined mandibular repositioning for the patient.
2. The set of mandibular repositioning devices of claim 1 , wherein:
(i) the upper splint comprises an upper left fin and an upper right fin, wherein the upper right fin has the same unchangeable first distance (UD) from the posterior end of the upper splint as the upper left fin, and
(ii) the lower splint comprises a lower left fin and a lower right fin, wherein the lower right fin has the same unchangeable first distance (LD) from the posterior end of the lower splint as the lower left fin.
3. The set of mandibular repositioning devices of claim 1 , wherein:
each of the at least one upper splint comprises a second upper fin located at a second distance UD from the posterior end of the respective upper splint; and
each of the at least one lower splint comprises a second lower fin located at a second distance LD from the posterior end of the respective lower splint; and
wherein the second upper fin comprises an upper fin front surface and the second lower fin comprises a lower fin back surface, such that when the respective upper splint and the lower splint are worn at the same time by the patient, the upper fin front surface of the second upper fin contacts the lower fin back surface of the second lower fin, thereby causing a defined mandibular repositioning for the patient.
4. The set of mandibular repositioning devices of claim 1 , wherein the set comprises one lower splint and at least two upper splints, and each upper splint has a different first unchangeable first distance (UD), resulting in a different mandibular repositioning offset when the upper and the lower splints are fitted onto the upper and lower dentitions, respectively.
5. The set of mandibular repositioning devices of claim 1 , wherein the set comprises one upper splint and at least two lower splints, and each lower splint has a different first unchangeable first distance (LD), resulting in a different mandibular repositioning offset when the upper and the lower splints are fitted onto the upper and lower dentitions, respectively.
6. The set of mandibular repositioning devices of claim 5 , wherein the first, second and third mandibular repositionings each differ by an increment of from 0.5 mm to 6.0 mm, in no particular order.
7. The set of mandibular repositioning devices of claim 1 , wherein the first and second mandibular repositionings are in increments of from between about 0.5 mm to 6.0 mm.
8. The set of mandibular repositioning devices of claim 1 , wherein the total number of the at least one upper splint plus the total number of the at least one lower splint is at least four to generate a third combination of upper splint and lower splint to generate a third mandibular repositioning when an upper splint and a lower splint are worn at the same time by the patient, wherein the third mandibular repositioning is different than the first mandibular repositioning and the second mandibular repositioning.
9. The set of mandibular repositioning devices of claim 1 , wherein a rake angle of the upper fin front surface or a rake angle of the lower fin back surface is selected from the group consisting of a neutral angle, a recline angle, and a procline angle.
10. The set of mandibular repositioning devices of claim 1 , wherein the at least one upper splint and the at least one lower splint contact each other along the patient's occlusal plane when the at least one upper splint and the at least one lower splint are fitted onto the upper dentition and the lower dentition, respectively, and the patient's mouth is closed.
11. The set of mandibular repositioning devices of claim 1 , wherein the respective image of the upper dentition is used to make each of the at least one upper splints, and the respective image of the lower dentition is used to make each of the at least one lower splints.
12. The set of mandibular repositioning devices of claim 1 , wherein each of the at least one upper splints and each of the at least one lower splints independently comprise an open center, wherein the open center is adapted to accommodate the patient's tongue when the at least one upper splint and the at least one lower splint are fitted onto the upper dentition and the lower dentition, respectively.
13. The set of mandibular repositioning devices of claim 1 , wherein the upper splint and the lower splint comprise a transparent material.
14. The set of mandibular repositioning devices of claim 1 , wherein the at least one upper splint and the at least one lower splint comprise ball clasps and/or retention arms.
