a second splint configured to fit onto the dentition, the second splint comprising the imprint of the dentition configured to fit onto the dentition;
a second fin coupled to the second splint to be located at a second distance from a back of the second splint, wherein the first distance is different from the second distance;
an opposing splint configured to fit onto an opposing dentition of the patient to oppose the first or second splint when the first or second splint fits onto the dentition, the opposing splint comprising an imprint of the opposing dentition configured to fit onto the opposing dentition; and
an opposing fin coupled to the opposing splint and configured to:
contact the first fin to reposition the mandible based on the first distance when the first splint fits onto the dentition and the opposing splint fits onto the opposing dentition to oppose the first splint, and
contact the second fin to reposition the mandible based on the second distance when the second splint fits onto the dentition and the opposing splint fits onto the opposing dentition to oppose the second splint.
2. The set of splints of claim 1 , wherein
the first fin comprises a first left fin and a first right fin, wherein the first right fin has the same first distance from the back of the first splint as the first left fin,
the second fin comprises a second left fin and a second right fin, wherein the second right fin has the same second distance from the back of the second splint as the second left fin, or
the opposing fin comprises an opposing left fin and an opposing right fin, wherein the opposing right fin has the same distance from a back of the opposing splint as the opposing left fin.
3. The set of splints of claim 1 , wherein the first and second splints are upper splints configured to fit onto the dentition being an upper dentition, and the opposing splint is a lower splint configured to fit onto the opposing dentition being a lower dentition.
4. The set of splints of claim 1 , wherein the first and second splints are lower splints configured to fit onto the dentition being a lower dentition, and the opposing splint is an upper splint configured to fit onto the opposing dentition being an upper dentition.
5. The set of splints of claim 1 , wherein the opposing fin is configured to contact the first fin to reposition the mandible as a first mandibular repositioning based on the first distance when the first splint fits onto the dentition and the opposing splint fits onto the opposing dentition, and contact the second fin to reposition the mandible as a second mandibular repositioning based on the second distance when the second splint fits onto the dentition and the opposing splint fits onto the opposing dentition.
6. The set of splints of claim 5 , wherein the first and second mandibular repositionings are in increments of from between about 0.5 mm to about 6.0 mm.
7. The set of splints of claim 5 , wherein the first mandibular repositioning is a repositioning prescribed by a doctor, and the second mandibular repositioning is a non-zero increment from the first mandibular repositioning.
8. The set of splints of claim 5 , wherein the total number of the set of splints is at least four to generate a third combination to generate a third mandibular repositioning when two splints among the set of splints 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 splints of claim 8 , wherein the first, second and third mandibular repositionings each differ by an increment of from about 0.5 mm to about 6.0 mm, in no particular order.
10. The set of splints of claim 6 , wherein the first mandibular repositioning is a mandibular repositioning prescribed by a doctor, and the second mandibular repositioning and third mandibular repositioning are nonzero increments from the first mandibular repositioning.
11. The set of splints of claim 1 , wherein one imprint or image of the dentition is used to make the first splint or the second splints, or one imprint or image of the opposing dentition is used to make the opposing dentition.
12. The set of splints of claim 1 , wherein the first splint, the second splint, and the opposing splint independently comprise an open center, wherein the open center provides room for a tongue of the patient when wearing the first splint, the second splint, or the opposing splint.
13. The set of splints of claim 1 , wherein the first splint, the second splint, the opposing splint, or a combination thereof are milled using a milling machine using a computer aided design (CAD) file to direct the milling such that the accuracy of data from an impression of a patient's anatomy, a fit, and the design of the first splint, the second splint, the opposing splint, or the combination thereof are transferred to a milling machine.
14. The set of splints of claim 1 , wherein the first splint, the second splint, the opposing splint, or a combination thereof comprise a ball clasps and/or a retention arms.
15. The set of splints of claim 1 , wherein the first fin or the second fin is affixed to a first splint buccal to a buccal surface of maxillary teeth, and the opposing fin is affixed to an opposing splint buccal to a buccal surface of mandibular teeth.
16. The set of splints of claim 15 , wherein
(a) the first fin or the second fin is affixed to the first splint buccal to the buccal surface of maxillary teeth, and when the first splint or the second splint is fit onto maxillary dentition the first fin or the second fin protrudes downward below the occlusal plane of the first splint;
(b) the opposing fin is affixed to the second splint buccal to the buccal surface of mandibular teeth, and when the opposing splint is fit onto mandibular dentition the opposing fin protrudes upward above the occlusal plane of the opposing splint; or
