Disclosed is a denture tray for visual marking and a manufacturing method thereof. The method comprises: establishing a three-dimensional model of a target dentition of a target patient; obtaining a three-dimensional model of a substrate of a denture tray based on the three-dimensional model of the target dentition; providing a through hole at a preset position on the three-dimensional model of the substrate of the denture tray; establishing a three-dimensional model of a fixed connection portion on an outer side surface of the three-dimensional model of the substrate of the denture tray to form a three-dimensional model of the denture tray, wherein the three-dimensional model of the fixed connection portion is integrally connected with the three-dimensional model of the substrate of the denture tray; and manufacturing the denture tray based on the three-dimensional model of the denture tray.

The inventive film clamping element (10) is held using a lip ring (14) and a vestibular ring (16), between which and possibly beyond which a film (12) extends. The film (12) and also said rings (14, 16) are elastically deformable and it is provided that the film (12) comprises an attachment (24, 26) each at two positions opposite one another. Between these attachments (24, 26) at least one elastic band (20, 22) extends which is suitable to constrict the film (12) radially towards the inside.

An orthodontic system including a first appliance configured to removably couple to a maxilla of a mouth of a patient. The first appliance having a first tray and a first expansion screw assembly. The first tray defines a first segment, a second segment, and a third segment. The first tray includes a first bite block extending from one of the first or second segments on a first side of the orthodontic system. The first expansion screw assembly is coupled to the first tray having a first expanding screw and a second expanding screw that are selectively movable to enable the first, second, and third segments of the first tray to move relative to one another.

An oral appliance is provided for delivering a medicament to at least a portion of teeth and/or soft tissue areas inside a mouth. The oral appliance contains an interior surface having a medicament disposed in or on at least a portion of and/or the entire interior surface of the oral appliance. The interior surface of the oral cavity is formed to fit contours of at least the portion of the teeth and/or soft tissue areas inside the oral cavity and is configured for holding the medicament in contact with at least the portion of the teeth and/or soft tissue areas inside the oral cavity to deliver the medicament to strategic areas in need of treatment. In some embodiments, computer, network and computer readable storage media are provided.

Cheek retraction devices including an upper frame element configured to bear against and retract soft oral tissue from one or more teeth of an upper dental arch, a lower frame element configured to bear against and retract soft oral tissue from one or more teeth of a lower dental arch. The upper and lower frame elements may each include left and right frame portions wherein the upper and lower left frame portions are joined to one another to form a v-shaped hinge on one side of the frame, while upper and lower right frame portions are joined to one another to form a v-shaped hinge on another side of the frame. The v-shaped hinges on opposed sides permit the upper and lower frame elements to be at least partially folded toward each other. A posterior frame element may be provided extending between the v-shaped hinges.

A chemical extraction apparatus has absorbent material for absorbing or adsorbing volatile chemicals from a breath of a user. The chemical extraction apparatus is positioned within such that breaths from the user flow over the absorbent material thereby causing volatile chemicals in the breaths to absorb or adsorb into the absorbent material. The absorbent material is then analyzed to determine the amount of chemicals absorbed or adsorbed into the absorbent material. Based on such analysis, various diseases or conditions can be detected or diagnosed.

The preferred invention enables a hybrid approach to orthodontic care whereby the treatment for bracket and wire orthodontics can be performed in a combination of settingssometimes in-office and sometimes at home. The initial phase of treatment involves evaluation and planning up to the point when a patient has braces placed on their teeth in a clinical setting and the initial wires are engaged with or mounted to the patient's teeth. From that point forward the patent's treatment preferably involves a combination of in-office visits and adjustments coupled with remote adjustments performed by the patient themselves, under the remote supervision of a clinician. When treatment is complete, the patient preferably returns to a clinical office and has the braces removed. The preferred invention improves the quality of care, the efficiency of the clinician, minimizes errors, speeds treatment times, expands access to care and is much more convenient for patients.
