a first protrusion of the first splint to be located at a first distance from a posterior end of the first splint;
a second splint configured to fit onto the dentition;
a second protrusion of the second splint to be located at a second distance from a posterior end 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; and
an opposing protrusion of the opposing splint configured to:
contact the first protrusion 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 protrusion 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 protrusion comprises a first left protrusion and a first right protrusion, wherein the first right protrusion has the same first distance from the back of the first splint as the first left protrusion,
the second protrusion comprises a second left protrusion and a second right protrusion, wherein the second right protrusion has the same second distance from the back of the second splint as the second left protrusion, or
the opposing protrusion comprises an opposing left protrusion and an opposing right protrusion, wherein the opposing right protrusion has the same distance from a back of the opposing splint as the opposing left protrusion.
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 protrusion is configured to contact the first protrusion 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 protrusion 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 splint.
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 clasp and/or a retention arm.
15 . The set of splints of claim 1 , wherein the first protrusion or the second protrusion is affixed to the first splint buccal to a buccal surface of maxillary teeth, and the opposing protrusion 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 protrusion or the second protrusion 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 protrusion or the second protrusion protrudes downward below the occlusal plane of the first splint;
(b) the opposing protrusion 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 protrusion protrudes upward above the occlusal plane of the opposing splint; or
(c) a combination of (a) and (b).

19 . The set of splints of claim 1 , wherein the first or second splint and the opposing splint comprise a transparent material.
20 . The set of splints of claim 1 , wherein a gap is formed between the first protrusion and the first splint;
a gap is formed between the second protrusion and the second splint;
a gap is formed between the opposing protrusion and the opposing splint;
or any combination thereof.
