A mandibular positioning facial retrognathism orthodontic system and a design method thereof are disclosed. The orthodontic system includes a maxillary shell-like dental appliance having a shell-like body, a protrusion portion protruding toward an opposite jaw is disposed at a posterior area corresponding to the shell-like body, a traction portion is disposed at a labial side of the shell-like body, and a retaining portion configured for fastening with a retaining attachment is disposed at the posterior area corresponding to the shell-like body. The protrusion portion is engaged with the posterior area of a mandibular for occlusal reconstruction, so that mandibular incisors are aligned with maxillary incisors. The design method is a design method for the mandibular positioning facial retrognathism orthodontic system, which can provide a treatment-specific orthodontic system, thereby achieving treatment of mandibular positioning facial retrognathism.

Tool for handling palatal expanders, including two opposed jaws adapted to clamp at least one body of a palatal expander, a handle, and actuation means adapted to move said jaws between a clamping position on said at least one body and respectively a release position, said jaws being bound elastically to one another and are normally spaced from each other, and said actuation means comprising a slider slidably mounted on the outer surfaces of the jaws, the slider being provided with a part adapted to interact with said outer surfaces so as to compress the jaws by pushing them toward each other when it is made to slide along a first direction and free them when it is made to slide along a second direction, said actuation means being adapted to firmly but reversibly lock the jaws in said clamping position.

Systems, devices and methods are disclosed for reshaping airways concurrently with dental and/or orthodontic treatment. The systems can have a series of two or more oral appliances configured to progressively reposition the maxillary and mandibular teeth in two or more successive steps. Each oral appliance in the series can have one or more maxillary blocks, one or more mandibular blocks, a maxillary oral tray, and a mandibular oral tray. One or more maxillary blocks can be attached to or integrated with the maxillary oral tray. One or more mandibular blocks can be attached to or integrated with the mandibular oral tray. The maxillary and mandibular oral trays can be configured to move one or more teeth from a tooth first position to a tooth second position. The maxillary and mandibular blocks can be configured to interact with one another to treat sleep breathing disorders.

Palatal expander apparatuses for expanding a patient's palate (“palatal expanders”) and methods of using and making them. These palatal expanders may be configured to have a variable surface smoothness on one side (e.g., the lingual-facing surface) compared to the opposite side (e.g., the palatal-facing surface). These palatal expanders may be configured to have a varying thickness in the palatal region. These palatal expanders may be adapted for ease in removal by the patient or caregiver (e.g., including a hinged region and/or detachment region, and/or including a thinner buccal side then occlusal side, etc.).

An orthodontic screw and a set of elements for forming an orthodontic or orthopedic appliance for dentistry, as well as a method for making an orthodontic or orthopedic appliance for dentistry. The orthodontic screw includes two bodies connected by positioning elements designed to allow the distance between the bodies to be adjusted; the bodies have a seat adapted to receive a portion of a connection structure associable with the orthodontic screw for its connection to the teeth of a dental arch; the seat has a groove formed on an external surface of the bodies, so that said portion of said connection structure can be inserted in the seat through a displacement orthogonal to the same seat.

The present disclosure provides methods, systems, devices, and kits for creating composite materials from a single resin, the composite materials having multiple continuous phases. The disclosure includes a process to three-dimensionally print objects (e.g., orthodontic appliances) with composite properties. In some aspects, the composite properties are formed from a single formulation with components that, when processed, have hard and soft continuous phases. In some aspects, the composite properties are formed by separately processing the hard phase components and the soft phase components. In some aspects, the composite materials and devices are three-dimensionally printed using the processed material.
