A film tensioning element is provided for dental applications with a film extending between tensioning rings. The film has a modulus of elasticity of less than 2 KN/mm.sup.2. The film is made of a tough plastic with a modulus of elasticity of more than 1 KN/mm.sup.2, in particular of PP, or optionally of PA. The film tensioning element is manufactured together with the tensioning rings.

In one embodiment, an aspiration prevention system is configured to keep items from moving from a mouth of a patient into a throat of the patient. The system includes a mouth prop, a frame, and an air-permeable barrier. The mouth prop has a top surface configured to abut top teeth of the mouth, a bottom surface configured to abut bottom teeth of the mouth, and a frame coupling feature. The frame has a barrier retention feature configured to retain an air-permeable barrier, and a prop coupling feature that is attachable to the frame coupling feature of the mouth prop in a position in which the frame at least partially covers the throat.

Techniques are described for automating the design and manufacture a dental restoration appliance for restoring the dental anatomy of a patient. For example, a system processes a digital three-dimensional (3D) model of a future (desired) dental anatomy of a patient, the future dental anatomy representing an intended shape of at least one tooth of the patient. The system includes a landmark identifier configured to automatically compute, based on the digital 3D model of the future dental anatomy of the patient, one or more landmarks of the future dental anatomy of the patient. The system also includes a custom feature generator configured to automatically generate, based on the one or more landmarks, one or more custom appliance features for a dental appliance for restoring the at least one tooth of the patient. The system further includes a memory device configured to store a digital model of the dental appliance.

A dental matrix includes an outwardly extending column, which is engaged by an instrument, allowing the dentist to move the instrument and maneuver the matrix into position on the operative tooth to create a cavity for the veneer. The cavity is filled with curable material, which is cured by light, such as ultraviolet light, and once curing is complete, the matrix is removed from the tooth, which now has the veneer formed thereon.

Compound dental floss is a single loop or double loop self-ligaturing tie tied to its loop one, two or multiple regular ties. It is used for rubber dam isolation to hold rubber dam sheet in place around the teeth and prevent it from moving or sliding during dental treatment.
