Manufacturing method and application of pressed film material functional appliance

Abstract

The invention discloses a manufacturing method and application of a pressed film material functional appliance, and belongs to the technical field of oral treatment. The manufacturing method comprisesthe following steps: preparing an impression, wherein preparing upper and lower jaw tooth retention film; transferring a occlusal relationship; reconstructing occlusion; fixing and reconstructing theocclusal relationship wherein blending a dental self-setting plastic material, and fixing and connecting rear tooth sections of the upper and lower jaw tooth retention film into a whole at the reconstructed occlusal relationship position; removing the lower anterior tooth retention film: cutting off the lower anterior tooth retention film. According to the manufacturing method, the lower jaw dentition ultrathin retention film is moved forwards by 4-8 mm to be fixed to the ultrathin retention film of the upper jaw dentition, the ultrathin retention film of the lower jaw anterior teeth is removed, and a space and a channel for free movement of the tongue body when the mouth is opened for speaking are reserved.

Description

technical field [0001] The invention belongs to the technical field of oral cavity treatment, and in particular relates to a production method and application of a pressure film material functional appliance. Background technique [0002] Angle's malocclusion is one of the common malocclusions, accounting for about one-third of the total number of malocclusion patients. Most Angle's malocclusions are skeletal deformities, which are difficult to treat, especially moderate and severe Angle's malocclusions often require surgery to be significantly improved. Angle's malocclusion is formed during growth and development, so orthodontists have been working on functional correction methods during growth and development for a century, hoping to effectively control the formation of skeletal Angle's malocclusion , Invented hundreds of functional orthotics for Angle’s malocclusion, including muscle activator, bioregulator, Frankle invented decades ago, Twinblock, Forsus, MA, etc. inven...

Problems solved by technology

However, the more effective ones have the disadvantages of large size, uncomfortable wearing, affecting the appearance, occupying tongue space, blocking tongue movement, and seriously affecting pronunciation. It is difficult for patients to insist on wearing them, especially when the patient relaxes or sleeps, the jaw relaxes. It hangs down and cannot enter the effective position of the appliance through the guide surface of the appliance, so it also loses the role of guiding the mandible forward

The above two shortcomings lead to the failure of most patients to achieve good results
