The anterior section of the bite tray can have an arcuate curvature and a bite surface adapted to reflect the prevalent shape of a glenoid fossa.
1 . A dental appliance comprising:
a bite tray comprising:
opposing first and second posterior sections for positioning between upper and lower posterior teeth of the wearer;
an anterior section disposed between the first posterior section and the second posterior section, the anterior section having an arcuate curvature and having a bite surface adjacent a buccal tray edge disposed at less than 90 degrees to form a valley.
2 . The dental appliance of claim 1 wherein the bite surface or a lingual edge of the anterior section is formed to reflect a prevalent shape of a glenoid fossa.
3 . The dental appliance of claim 1 further comprising a formable portion disposed adjacent the bite tray.
4 . The dental appliance of claim 1 wherein the bite tray accommodates the curve of Wilson and the curve of Spee.
5 . The dental appliance of claim 1 wherein the bite surface of the anterior section is adapted to prevent lower anterior teeth of the wearer from traumatically contacting the bite surface of the anterior section of the bite tray.
6 . The dental appliance of claim 1 wherein the anterior section is adapted to distribute a load between the upper teeth and lower teeth away from anterior teeth and toward the posterior teeth of the wearer.
7 . The dental appliance of claim 3 wherein the formable portion further comprises opposing first and second posterior sections for positioning between the upper and lower posterior teeth of the wearer, and an anterior section disposed between the first posterior section and the second posterior section, the anterior section having an arcuate curvature and having a formable bite surface inclined from a lingual edge towards a buccal edge.
8 . The dental appliance of claim 3 wherein the formable portion further comprises opposing first and second posterior sections for positioning between upper molars and lower molars of the wearer, the posterior sections having a formable bite surface, the formable bite surface having a concave curvature.
9 . The dental appliance of claim 3 wherein the formable portion is adapted to register upper teeth of a wearer and the bite tray is adapted to contact lower teeth of the wearer.
10 . A dental appliance comprising:
a bite tray; and
a formable portion disposed within the bite tray, the formable portion comprising:
opposing first and second posterior sections for positioning between upper and lower posterior teeth of a wearer;
an anterior section disposed between the first posterior section and the second posterior section, the anterior section having an arcuate curvature and having an anterior formable bite surface inclined from a lingual edge towards a buccal edge.
11 . The dental appliance of claim 10 wherein the posterior sections of the formable portion further comprise a posterior formable bite surface, the formable bite surface having a concave contour.
12 . The dental appliance of claim 10 wherein bite tray further comprises opposing first and second posterior tray sections for positioning between the upper and lower posterior teeth of the wearer and an anterior tray section disposed between the first posterior tray section and the second posterior tray section, the anterior tray section having an arcuate curvature and forming a tapered valley.
13 . The dental appliance of claim 11 wherein the posterior formable bite surface is adapted such that the upper posterior teeth of the wearer contact the first and second posterior sections before anterior teeth of the wearer contact the anterior section when the appliance is being fitted.
14 . The dental appliance of claim 10 wherein a shape of the formable portion is moldable when the dental appliance is heated to a forming temperature and the bite tray retains its shape at the forming temperature.
15 . A dental appliance comprising:
a bite tray; and
a formable portion disposed within the bite tray, the formable portion comprising:
opposing first and second posterior formable sections for positioning between upper and lower posterior teeth, the posterior formable sections having a formable bite surface with a concave contour.
16 . The appliance of claim 15 wherein the concave contour of the formable bite surface being such that a lingual edge of the first and second posterior sections is thicker than a buccal edge of the first and second posterior sections.
17 . The appliance of claim 15 wherein the concave contour of the formable bite surface is adapted to align a lingual cusp of a molar with a centerline of the formable bite surface.
18 . The appliance of claim 15 wherein the formable bite surface is configured to adapt to a buccal inclination of the upper posterior teeth.
19 . The appliance of claim 15 wherein the bite tray conforms to a lingual inclination of the lower posterior teeth.
20 . A method of manufacturing a dental appliance, the method comprising:
forming a bite tray having opposing first and second posterior sections for positioning between upper and lower posterior teeth of the wearer and an anterior section disposed between the first posterior section and the second posterior section, the anterior section having a bite surface disposed adjacent a buccal edge to form a tapered valley.
21 . The method of claim 20 further comprising forming a formable portion within the bite tray.
22 . The method of claim 21 wherein forming the formable portion comprises forming formable posterior sections having a concave curvature.
23 . The method of claim 21 wherein forming the formable portion further comprises forming formable posterior sections having a lingual edge and a buccal edge, wherein the lingual edge is thicker than the buccal edge.
24 . A dental appliance comprising:
a bite tray comprising:
opposing first and second posterior sections for positioning between upper and lower posterior teeth of the wearer;
an anterior section disposed between the first posterior section and the second posterior section, the anterior section having an arcuate curvature substantially matching a curvature of a dental arch and having a contoured bite surface adapted to prevent lower anterior teeth of the wearer from contacting the bite surface of the anterior section of the bite tray.
