The invention discloses an oral appliance comprising maxillary band rings, connecting members, a connecting rod and guiding plates, wherein the maxillary band rings are used for sleeving maxillary posterior molars, the connecting rod is used for connecting the maxillary band rings at the left and right sides, and the shape of the connecting rod is consistent with the shape of an maxillary dental arch; each connecting member comprises fixing columns, a connecting cross bar and fixing nuts, the fixing columns are fixed on the lingual side of the maxillary band rings, through holes matching the connecting cross bar is disposed on the fixing columns, and both ends of the connecting cross bar are provided with external threads matching the fixing nuts, and each guiding plate is provided with aconnecting hole matched with the connecting cross bar. The guiding plates are arranged on the oral appliance, buccal crossbite of the posterior molars of a patient can be corrected by the outward-pushaction of the guiding plates on the mandibular molars; the oral appliance does not need to use a planting nail and a rubber band for traction, is convenient for a doctor to operate, and improves thepatient's comfort to a certain extent degree; and the oral appliance is applied to the mild buccal crossbite of the posterior molars.

The invention discloses a manufacturing method of an implant guide plate, and belongs to the technical field of implant guide plates, which comprises the following steps: (1) covering a disinfected x-ray radiation-resistant material on an edentulous area, then fixing by using a silicone rubber impression material, and measuring the thickness of a buccal tongue side mucosa of the edentulous area through CBCT (Cone Beam Computed Tomography) scanning; (2) preparing a silicone rubber impression of a dental arch in an edentulous area by using a tray; (3) calibrating the middle point of the near-far middle direction of implant implantation in the tooth-missing area of the silicone rubber impression, and then calibrating the middle point of the buccal-tongue direction of implant implantation by referring to the mucosa thickness of the buccal-tongue side measured on CBCT (Cone Beam Computed Tomography); (4) inserting the prefabricated cylinder into a preset position; (5) pouring a plaster model into the silicone rubber impression, and fixing the cylinder at the same time; (6) after the gypsum is solidified, taking out the model from the impression; and (7) sleeving a prefabricated channel fixer, and pressing a film or manufacturing a guide plate by using self-setting resin. According to the technical scheme, anesthetic injection can be avoided, manufacturing steps are simplified, guiding and positioning are accurate, and cost is low.
