Description
Technical Field
The utility model belongs to the technical field of oral auxiliary medical appliances, and particularly relates to an orthodontic occlusion recording device combined with a digital oral scanning.
Background
Bite registration is the key to obtaining intraoral models during dental correction. Accurate bite registration can ensure minimal intraoral blending, thereby saving overall treatment time and expense. With the development of artificial intelligence technology in recent years, digitization technology is gradually applied to the oral cavity field. The digital model obtained by intraoral scanning gradually replaces the intraoral impression to prepare the entity impression, so that the clinical operation time is greatly shortened, the precision reaches the clinical standard, and multiple occlusion records can be carried out. However, dental waxes have been widely used for bite registration in clinical work to date, mainly because dental waxes are inexpensive and easy to handle: only heating, shaping and placing into the oral cavity are needed. However, the existing dental wax is required to be manually formed into a preset shape and then placed into a mouth of a patient to acquire an occlusion record, and then transported to a manufacturer for producing the appliance, deformation is easy to occur in the process, and the deformed occlusion record can cause design deviation when the dental appliance is designed, so that the final correction effect of the patient is affected. In addition, in the case of a jaw-dislocation deformity having a jaw position relationship, it is generally necessary to acquire not only an actual occlusion state in the mouth of a patient but also a relative positional relationship between the upper and lower jaws after the upper and lower jaws are opened by a predetermined occlusion relationship when acquiring the upper and lower jaw occlusion records. The prior art lacks a bite registration device that combines the digital oral scanning technique that can easily acquire digital models and bite registration.
