A process for determining a tooth color of a filling or another restoration is provided which in particular is produced using composite materials, wherein at least one tooth is scanned or is visually detected. The process is characterized in that natural teeth are spectrally measured in advance, that the color values measured within a color space are classified into several, in particular four, categories which each form a color cloud extending in a three-dimensional fashion within the color space, which is done with the help of a structuring algorithm, in particular a Nearest Neighbour Algorithm, or a symmetry recognition algorithm, and that the tooth color of the filling is determined by means of evaluating to which category the tooth scanned has the smallest color distance, or to which color cloud the tooth scanned belongs.

A device for the relative positioning of the lower and upper jaws of a subject that includes splints intended to be disposed on the dental arches of the lower and upper jaws of the subject and linked by link members disposed in an occlusal position, between the splints, each link member includes posterior and anterior end parts made secure and articulated on a respective occlusal face of the upper and lower splints, so as to stress said lower splint in a forward direction. Each link member is composed of a rigid link rod of fixed length whose posterior end part is on the upper splint and in that the position of the posterior end part of each rigid link rod is longitudinally adjustable in the occlusal plane so as to adjust the position of the lower splint.

A dental stent for tooth restoration, comprising an acrylic outer shell and a set of metal matrix separator strips partially embedded into an inner silicon bed; a method of manufacturing a dental stent including 3D printing of a model wherein tooth forms of teeth to be restored are individually removable from a remainder of the model; a method of tooth restoration using a dental stent, and a kit of parts comprising a dental stent and a composite resin, and optionally a heater, a light cure unit, and a finishing tool kit.

The invention relates to the application of a composition containing recombinant amelogenin and propylene glycol alginate (“PGA”) on to cut dentin tubules followed by installation of a definitive restorative in a single visit.

An orthodontic mould to be applied to one or more of a patient's teeth, the mould having: at least one cavity configured to be positioned adjacent a respective tooth of the patient, with the at least one cavity to receive a settable material to provide a projection, the projection to be fixed to a respective one of the teeth; and a rod or stint mounted in the mould and extending from the at least one cavity so as to be secured to the projection when the settable material is set.

A dental stent for tooth restoration, includes an acrylic outer shell and a set of metal matrix separator strips partially embedded into an inner silicon bed. A method of manufacturing a dental stent includes 3D printing of a model wherein tooth forms of teeth to be restored are individually removable from a remainder of the model. A method of tooth restoration uses a dental stent, and a kit of parts including a dental stent and a composite resin, and optionally a heater, a light cure unit, and a finishing tool kit.

Provided are compositions and devices containing microspheres encapsulating one or more drug(s). The compositions and devices may be used to treat or prevent infection associated or caused by oral mucosal diseases, oral infections, oral conditions, dental conditions, or surgical recovery. The devices include, but are not limited to, splints, mouth guards, full dentures, partial dentures, or fillings. The devices may be manufactured from filaments that have a composition of the present disclosure. Also provided are methods of making and using the devices and compositions.

A tooth restoration method and a tooth restoration system are provided. The tooth restoration method includes: configuring a control module to obtain an image and tooth characteristic information of teeth through an image capturing module; configuring the control module to calculate and generate a characteristic parameter of the target tooth according to the image and the tooth characteristic information, and generate a 3D restoration file of the target tooth according to the characteristic parameter; configuring the control module to calculate and generate color information and candidate filling materials of the target tooth according to the image, the 3D restoration file and the filling material database, and compare the candidate filling materials with the characteristic parameter and the color information of the target tooth to generate a selected filling material matching the target tooth; and restoring the target tooth based on the selected filling material through a prosthetic technique.

A medical apparatus including a bar with a first attachment loop, a second attachment and a plurality of hooks, wherein the medical apparatus is an arch bar.

A device and method treating Trismus in a patient. The device is configured to be located completely within the mouth of the patient and includes a pair of teeth-receiving plates and at least one adjustable biasing assembly. The adjustable biasing assembly pivotably interconnects the teeth-receiving plates and is adjustable to establish a desired spacing between anterior portions of the teeth-receiving plates, and also provides a force to the teeth-receiving plates tending to bias the anterior portions of those plates to the desired spacing.
