Orthodontic aligner with non-planar bite structure for teeth
The granted patent US12064313B2 describes an innovative orthodontic aligner designed for the treatment of patients. The aligner features a shell that encompasses at least one cavity tailored to accommodate a patient's tooth. This cavity includes distinct portions: lingual, labial, and occlusal, with a specialized bite structure that does not conform to the tooth's occlusal surface. The bite structure is characterized by a non-planar surface with multiple projections, including outermost projections that form part of the sidewall and an additional projection surrounded by these outermost ones. The peaks of these projections create a concave tooth-engaging surface that follows the curvature of the tooth's occlusal surface, ensuring that when worn, the aligner maintains a specific distance from the tooth to prevent full jaw closure.
Additionally, the patent outlines various configurations and manufacturing methods for the aligner. It specifies that the outermost projections can be spherical or ellipsoidal and may be separated by a grid-like boundary. The bite structure is integral to the shell and is designed to compress minimally during treatment. The patent also details a method for creating a mold that includes these projections, allowing for the precise formation of the aligner's bite structure. This method involves thermoforming a worksheet over the mold to achieve the desired cavity and bite structure. Overall, the patent presents a comprehensive approach to orthodontic aligners, emphasizing both structural design and manufacturing techniques to enhance patient treatment outcomes.
