Problems solved by technology

[0004] However, in some cases, current orthodontic appliances may not be able to effectively generate the force required to achieve the desired tooth repositioning, or may not provide sufficient control over the force applied to the teeth
Additionally, the stiffness of some existing aligners may affect the ability of the aligner to bond to the patient's teeth and may increase patient discomfort

Embodiment Construction

[0023] To reposition one or more teeth, maintain the current position of one or more teeth, or an appropriate combination thereof, the orthodontic appliances described herein and their associated systems and methods can be employed as part of an orthodontic treatment process. The orthodontic appliance can include a plurality of discrete housing sections, each discrete housing section including a plurality of cavities shaped to receive at least some of the patient's teeth, utilizing a resilient material (also referred to herein as "Elastomer") to join multiple discrete shell segments to form a single aligner shell. The geometry, configuration and material properties of the housing segments and / or the resilient material can be selected to at least partially control the magnitude and direction of the force applied to the teeth by the aligner. In some cases, the applied force is provided in whole or in part due to the elastic material of the bonding section. In contrast to existi...

Abstract

Improved orthodontic appliances, along with related systems and methods, are provided. In one aspect, an orthodontic appliance is provided. The appliance includes a plurality of discrete shell segments, each including one or more cavities shaped to receive at least portions of teeth. The discrete shell segments are joined by an elastic material to form a single appliance shell.

Description

[0001] cross reference [0002] This application claims the benefit of US Provisional Application No. 61 / 969,023, filed March 21, 2014, which is hereby incorporated by reference in its entirety. Background technique [0003] Orthodontic procedures typically involve repositioning a patient's teeth into a desired alignment in order to correct a malocclusion and / or enhance aesthetics. To accomplish these purposes, orthodontic appliances such as braces, retainers, shell aligners, etc., can be applied to the patient's teeth by an orthodontist. The aligner is configured to apply force to more than one tooth in order to produce the desired tooth movement. The application of force can be adjusted periodically by the physician (eg, by changing the aligners or using a different type of aligners) in order to gradually reposition the teeth into the desired alignment. [0004] However, in some instances, current orthodontic appliances may not be able to effectively generate the force req...
