An orthodontic appliance for orthodontic treatment of a posterior maxillary sector extending from a mesial anchor tooth to a molar tooth unilaterally on the same side of the maxilla is provided. The appliance features a molar component, a mesial anchor tooth attachment, a long rod, and a hook. The long rod is saddle-shaped in the occlusal-gingival plane, and may have a distal step-down portion. The rod may extend at a mesial end thereof from the mesial anchor tooth attachment towards the molar component in a mesiodistal direction, and the rod may also have a mesial step-up portion starting from the mesial anchor tooth or premolar attachment. The hook may be located on the rod, for attachment with a traction element for direct molar traction. Under force of the traction element the rod exerts force on the molar component for molar distillation.

The invention discloses a maxillofacial fixing device for plastic surgery and a maxillofacial plastic surgery instrument, and belongs to the technical field of beauty instruments. According to the technical scheme, the device is characterized by comprising a fixing frame, wherein supporting devices which are uniformly distributed are fixedly connected to the inner bottom wall of the fixing frame; a headrest is fixedly connected to the tops of the supporting devices; clamping devices are arranged on the two sides of the fixing frame; the clamping devices penetrate through the fixing frame and extend into the fixing frame; air bags are arranged on the opposite sides of the two clamping devices; and inflation pipes are arranged on the opposite sides of the two air bags. Accordingly, by arranging an auxiliary opening device, the size of a medical lantern ring can be changed according to the specific condition of a patient, the patient can open the upper jaw bone and the lower jaw bone more precisely, surgery of medical staff is facilitated, and the treatment effect is better; and by arranging a second limiting rod and a circular limiting groove, a second bevel gear can be limited, the second bevel gear is prevented from deviating in the adjusting process, and normal and reasonable operation of the device is guaranteed.

The Male Threaded Implant Drill will assist in the process that will allow a surgeon to place a dental implant in the mandible and/or maxilla bone(s) while working in conjunction with a stent. The Male Threaded Implant Drill is used in the placement of a surgical dental implant perfectly parallel to other dental implant(s) and root structures. The Implant Drill is used in conjunction with a surgical dental implant stent that will allow a surgeon to place dental implant(s) at a predetermined depth within the mandible and/or maxilla of a patient undergoing surgery.

The invention relates to the field of medical instruments, and relates to an intraoral impression preparation device and an assembly for a maxillary defect patient. The device main body comprises a tray base and supporting units. A plurality of detachable supporting units are arranged on the tray base, the supporting units support and improve the connection strength between an impression materialand a tray, and the supporting units with different shapes can provide comprehensive strategic support for patients with various jaw defects. The tray base and the supporting units are used for loading the impression material, and the type, the number and the installation position of the supporting units are determined according to the shape of the defect cavity wall of the maxillary defect patient before the impression material is loaded. The assembly is mainly used for magnetic connection, removal and reset of multilayer impression. By adopting a matrix thought, the defect cavity position and the three-dimensional space information are reserved, meanwhile, the recording of the jaw defect cavity is improved from integral replacement to local fine adjustment, a layering mode aiming at complex cases is combined, the technical difficulty of clinical operation is reduced, the injury of the patient is reduced, and the safety of the impression preparation is improved.

A maxillary skeletal expander is proposed. The maxillary skeletal expander is composed of a pair of dental arch expansion bodies positioned to face each other in an oral cavity; an expanding screw provided between the pair of dental arch expansion bodies to move the dental arch expansion bodies; a guide provided between the pair of dental arch expansion bodies to safely move the dental arch expansion bodies without deviation; a dental arch expansion body combining means having a fixing piece for penetrating a fixing hole at a selected part in the oral cavity, and configured to be combined to and separated from each of the dental arch expansion bodies.

A hygienic oral pacification device includes a fluid-filled bladder. The bladder includes a nipple and alveolar ridge-mating flanges. The bladder is dynamically shaped and allows for pressures provided by the suckling child to re-shaping the bladder and flanges. A bite-block extends into the bladder to maintain a fluid path from nipple to flanges. As the child completes the suckling cycle, the bladder nipple is depressed and fluid is forced in the engorging flanges. The flanges thus cover the alveolar ridges and fill the vestibules. Hard pads set along a superior surface of the nipple are compressed against the maxilla palate and provide lateral force to encourage expansion of the palate. The nipple may be bifurcated into left and right opposing lobes which can split laterally to enhance lateral force on maxilla.
