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. A 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 the 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;
wherein the guiding mechanism comprises a guiding channel, wherein the guiding channel is an indentation in the body of the splint, and wherein 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 the superior wall; and
at least one tine at the inferior wall.
2. The splint of claim 1 , wherein the splint is an upper splint or a lower splint.
3. The splint of claim 1 , wherein a gap between the guided fin and the splint at the posterior-most position of the guided fin is substantially the same width as the gap between the guided fin and the splint at the anterior-most position of the guided fin.
4. The splint of claim 1 , wherein the guiding mechanism comprises a positive stop at the anterior end of the guiding mechanism.
5. The splint of claim 1 , wherein the guiding mechanism further comprises at least one stabilizing rod connecting the back post to the guided fin.
6. The splint of claim 1 , wherein the guided fin comprises a guide rail, attached to the splint side of the guided fin.
7. The splint of claim 6 , 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 core section, while the inferior edge of the guide rail abuts the inferior wall of the core section.
8. The splint of claim 1 , wherein the guiding mechanism comprises:
a guide groove cut along the side of the splint and a guide rail on the guided fin; or
a guide rail on the splint and a guide groove cut along the side of the guided fin.
9. The splint of claim 8 , wherein:
the guide groove forms a superior wall and an inferior wall;
the guide rail comprises a superior edge, which is parallel to the superior wall of the guide groove;
the guide rail comprises an inferior edge, which is parallel to the inferior wall of the guide groove.
10. The splint of claim 9 , wherein the superior edge and/or the inferior edge are at an angle with respect to the transverse plane.
11. 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 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 one or more guided fins and the respective back post is changed when the threaded rod is turned either clockwise or counterclockwise;
at least one stabilizing rod connecting the back post to the guided fin;
a guiding mechanism, comprising:
a positive stop at the anterior end of the guiding mechanism;
a guiding channel, wherein the guiding channel is an indentation in the 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 the superior wall; and
at least one tine at the inferior wall; and
the guided fin comprises a guide rail, attached to the splint side of the guided fin, 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 core section, while the inferior edge of the guide rail abuts the inferior wall of the core section.
