Improved methods for indirect bonding of orthodontic appliances, such as brackets, to the tooth surfaces of dental patients are provided. The methods use a transfer tray to accurately position the brackets on the tooth surfaces. Preferably, the tray is made of an ethylene vinyl acetate copolymer (EVA)/siloxane material. The brackets are coated with a protective coating to prevent them from becoming embedded in the tray. Preferably, a translucent, blue-tinted coating is used to cover the brackets. Dental restorative materials are used to bond the brackets to the teeth. The transfer tray is then removed from the mouth, while the appliances remain firmly bonded to the tooth surfaces.

Systems and methods for analyzing dynamic occlusion during replicated excursions of virtual three-dimensional representations of a dental patient's occlusal complex are provided. The method may include scanning a patient's jaws and teeth configuration using a medical imaging system such as CBCT, laser scanners, or traditional dental impressions; creating a virtual three-dimensional representation of the patient's occlusal complex; replicating excursions of the virtual three-dimensional representation of the patient's occlusal complex based at least on virtual inter-condylar angles and distances; determining acceptable occlusal contacts and/or malocclusions within the virtual three-dimensional representation of the patient's occlusal complex based at least in part on virtual dynamic occlusion during the replicated excursions, and determining at least one virtual dental appliance and/or orthodontic repositioning of one or more teeth based at least in part on the one or more acceptable occlusal contacts and/or malocclusions within the virtual three-dimensional representation of the patient's occlusal complex.

An orthodontic appliance and method of pre-applying two dental restoratives thereto of specific viscosities, the appliance including a main body having a bonding tooth-facing surface and retentive elements disposed over a tooth-facing bonding surface. The first dental restorative is applied onto the tooth-facing surface and retentive elements, the first dental restorative having a very low viscosity and being flowable and thus capable of fully penetrating into the retentive elements and being cured therein. The second dental restorative is applied over the cured first dental restorative and left uncured, the second dental restorative having a viscosity substantially higher than that of the first adhesive composition and being highly bondable to the cured first dental restorative and a tooth surface when later cured. The bracket having both the cured and uncured dental restoratives applied thereto is packaged and ready for direct or indirect bonding to teeth.

A dental articulator having an upper support member for supporting a dental cast and a lower support member for supporting a second dental cast. A polycentric hinge joint is provided for simulating the temporomandibular joint of a patient. The polycentric hinge joint comprises a fossae block secured to the upper support member and a condyle member secured to the lower support member which engages a fossae recess in the fossae block. A spring is provided for securing the lower support member to the upper support member and simulating the muscles used for mastication. A pair of wires are provided for simulating the ligaments of a patient. The upper end of each wire passes through an opening in the upper support member. The lower end of each wire is secured to the lower support member. A limiting block is provided on the upper end of each of the wires so as to restrict its movement.
