An apparatus and method to convert a dental, oral, orthodontic appliances, retainers, and dentures into a multifunctional oral appliance. The apparatus includes plurality of mechanical connectors and attachments made of plastic, ceramic, or metal, that convert any dental or oral appliances, into multipurpose, three dimensionally adjustable oral appliances for treating obstructive sleep apnea, snoring, temporomandibular joint and musculoskeletal disorders of the jaw, and for improving breathing from the mouth even when nasal passages are blocked.

An unimpeded distalizing jig, comprising a pair of tooth bond pads, an intra dental arch telescoping assembly, comprising a rod-like insertion and a tubular shell, which constrains the rod-like insertion to move with respect to the tubular shell along an elongated axis, which may be a radial path; and a force generating structure configured to supply an off-axis distalizing force to the intra dental arch telescoping assembly, such that the distalizing force is provided to the posterior tooth substantially without applying an anteriorizing force on the anterior tooth. The force generating structure may be an elastic band fixed by a hook to the tubular shell on one side, and to a molar on an opposing dental arch on the other side.

An oral appliance fixed to lower jaw teeth comprises a body having a shape corresponding to a teeth arrangement, a lower teeth recess formed in a lower portion of the body to allow lower jaw teeth to be inserted therein, an upper teeth recess formed in an upper portion of the body to allow upper jaw teeth to be inserted therein and allowing the lower jaw to move backward by a predetermined distance, and an upper teeth guide part formed to extend from the body to face a side of the upper jaw teeth. The lower teeth recess further comprises a lower molar fixing recess formed to strongly engage with at least a portion of left and right molars of the lower jaw teeth by frictional force, and a lower incisor recess formed to allow other lower jaw teeth except the left and right molars to position therein.

An orthodontic correction system is disclosed for correcting Class II malocclusions, Class III malocclusions, dental asymmetries and/or dental related skeletal anomalies in which the patient's dentition is permanent or near permanent. The correction system attaches to a patient's dentition via a novel orthodontic appliance that is affixed to, e.g., pre-installed upper and lower archwires. The correction system includes one or more adjustable length assemblies each of whose ends pivotally attach to a patient's preinstalled maxillary and mandibular archwires. Each pivot is a ball hinge comprising a spherical head that pivotally attaches, allowing the alignment assembly to have free excursion, motion, and/or rotation along multiple axes.

A dental coupling member related to a first aspect of the invention comprises: a rod having, at one end region, a first coupling part that is coupled to a first attachment part of a first dental tool, and having a screw part at the other end region; and a cylindrical body having, in an inner circumferential surface of one end region, a screwed part into which the screw part is screwed, and having, at the other end region, a second coupling part that is coupled to a second attachment part of a second dental tool. This dental coupling member comprises a different-torque part at the screw part and/or the screwed part, the different-torque part having a different torque for screwing against the other of the screw part and the screwed part. This dental coupling member suppresses the occurrence of loosening between the screw part and the screwed part.

An orthopedic appliance for a temporomandibular joint, includes: an upper teeth supporter and a lower teeth supporter, each of which includes a front arch portion corresponding to front teeth, and a pair of rear legs extended from the front arch portion, facing with each other and corresponding to a molar region; at least one set of upper and lower pivots which are respectively coupled to the upper teeth supporter and the lower teeth supporter and rotatable in at least one direction among forward, backward, leftward and rightward directions; and a connection member which connects the upper pivot and the lower pivot and adjusts a space between the upper pivot and the lower pivot. Thus, it is easy to adjust relative movement in a horizontal direction and height between the upper and lower teeth supporters.
