Adjustable oral devices for preventing or reducing snoring or obstructive sleep apnea (OSA)

An oral device comprising a first tray portion (16) configured for receiving at least a portion of an upper dental arch of an oral cavity of a wearer and a second tray portion (14) configured for receiving at least a portion of a lower dental arch of the oral cavity of the wearer, the first and second tray portions (14, 16) connected by two foldable flexible members or sections (18, 20) which are integrally formed with the first and second tray portions, the foldable flexible members or sections and the first and second tray portions further comprising mating means adapted to engage with each other;

• wherein the first and second tray portions (14, 16) together with the foldable flexible members or sections (18, 20) are capable of assuming a folded configuration within the oral cavity;
• and
• associated with each of the foldable flexible members or sections (18, 20) is an adjustment means (30, 32) which determine an apex of the fold of each flexible member or section (18, 20) when the oral device is in the folded configuration and thereby determine a relative position of the first tray portion (16) and the second tray portion (14) to the apex of each fold and of each tray portion to the other;
• wherein a location of a fold point of the foldable flexible members or sections by the adjustment means will determine the relative position of the first and second tray portions;
• wherein the adjustment means comprises a support member mounted on the first tray portion or the second tray portion and an adjustment member moveably mounted on the support member such that the adjustment member is capable of adopting a plurality of configurations for determining a plurality of locations for the apex of the fold when the oral device is in the folded configuration;
• and
• wherein the adjustment member comprises a pin having a threaded shaft (41) and a rounded head (44) against which the flexible members or sections abut in the folded configuration.

• wherein a location of a fold point of the foldable flexible members or sections by the adjustment means will determine the relative position of the first and second tray portions;
• wherein the adjustment means are each mounted partly one of the foldable flexible members or sections and partly on the first tray portion or the second tray portion such that the adjustment member is capable of adopting a plurality of configurations for determining a plurality of locations for the apex of the fold when the oral device is in the folded configuration.
