Methods and systems for creating orthodontic aligners with specific tongue spikes that work alone or in combination with other tongue spikes to provide protection against tongue thrust and to correct tongue thrust are disclosed. Three-dimensional computer modeling software is used to modify a three-dimensional model of the patient's teeth by creating a desired tongue spike and digitally adding a tongue spike to a tooth to protect the orthodontic aligner from forces resulting from tongue thrust.

An intraoral scanning apparatus has a mouthpiece and a transport apparatus that defines at least a first curved track within the mouthpiece. An image sensor is movable along the first curved track. A scanner is movable along the first curved track, scanning in synchronization with the image sensor and having an illumination source that has a laser light source and beam-shaping optics in the path of the laser light for forming a linear light pattern. At least one actuator is energizable to move the image sensor and scanner along the first curved track for image acquisition. A control logic processor synchronizes the scanner and image sensor for automated acquisition of surface contour data. A display is in signal communication with the control logic processor to process and display the acquired surface contour data.

An oral treatment assembly providing a plurality of medical treatments of a patient that are non-invasive and in particular, provides new methods for treating jaw related medical conditions of a patient through predetermined positioning and controlled or guided movement of a patient's mandible and therefore their mandibular condyles during use, wherein the assembly includes an upper and lower assembly each defining transition portions having a reverse cut angle that extends downward from the posterior forward to the anterior, and where each are configured to selectively engage to restrict the retrusion of the mandible relative to the maxilla and to position the mandible relative to the maxilla downward and in some embodiment slightly forward in a caregiver defined treatment position and having a caregiver defined treatment movement area thereabout. Since the reversed cut angle contains two vectors it also discourages involuntary dropping of the mandible relative to the maxilla.

An oral appliance for delivering a medicament to an inflamed tissue inside an oral cavity is provided. The oral appliance has an interior surface configured to contour at least a portion of teeth and/or soft tissue areas inside the oral cavity, the interior surface of the oral appliance having a medicament disposed at a discrete region of the interior surface of the oral appliance, the medicament configured to contact a top portion of the inflamed tissue inside the oral cavity when the oral appliance is worn to cause delivery of the medicament to at least the top portion of the inflamed tissue. A method of making the oral appliance and a method of treating an inflamed tissue inside an oral cavity using the oral appliance is also provided.

A dental intraoral device that is worn within an oral cavity, the dental intraoral device comprising a resin tooth portion. At least a part of the tooth portion is formed into a mesh shape. The part of the tooth portion is preferably formed by approximately regularly arranging unit regions having holes.
