Mandibular advancement device with guide channel
Disclosed herein are splints for a mandibular advancement device, each splint comprising one or more guided fins, wherein each guided fin is located at a distance D from back of the splint; a back post; at least one threaded rod connecting the back post to the guided fin, wherein the distance between the guided fin and the back post is changed when the threaded rod is turned either clockwise or counterclockwise; and a guiding mechanism.
1. An upper or a lower splint for a mandibular advancement device, the splint comprising:
one or more guided fins, wherein each guided fin is located at a distance D from a back of the splint;
a back post;
at least one threaded rod connecting the back post to the one or more guided fins,
wherein the distance between the one or more guided fins and the respective back of the splint is changed when each of the at least one threaded rod is turned either clockwise or counterclockwise;
at least one stabilizing rod connecting the back post to the one or more guided fins;
a guiding mechanism, comprising:
a positive stop at an anterior end of the guiding mechanism;
a guiding channel, wherein the guiding channel is an indentation in a body of the splint, and the guiding channel comprises:
a substantially rectangular core section, being at least partially bound by a posterior wall, an anterior wall, a superior wall, and an inferior wall;
a panhandle at a superior side; and
at least one tine at an inferior side; and
the one or more guided fins comprises a guide rail, attached to a splint side of the one or more guided fins, wherein the guide rail comprises a superior edge and an inferior edge, wherein the superior edge of the guide rail abuts the superior wall of the substantially rectangular core section, while the inferior edge of the guide rail abuts the inferior wall of the substantially rectangular core section,
wherein a gap between the guided fin and the splint at a posterior-most position of the guided fin is substantially the same width as the gap between the one or more guided fins and the splint at an anterior-most position of the one or more guided fins.
2. The splint of claim 1 , wherein the guiding mechanism comprises:
a guide groove cut along a side of the splint; or
a guide groove cut along the side of the one or more guided fins.
3. The splint of claim 2 , wherein:
the guide groove forms a superior wall and an inferior wall;
the superior edge of the guide rail is parallel to the superior wall of the guide groove; and
the inferior edge of the guide rail is parallel to the inferior wall of the guide groove.
4. The splint of claim 3 , wherein the superior edge and/or the inferior edge of the guide rail are at an angle with respect to a transverse plane.
