Abstract: Palatal expander apparatuses for expanding a patient's palate (“palatal expanders”) and methods of making them. The apparatuses may include a pair of tooth engagement regions connected by a palatal region. A detachment region on at least one of the tooth engagement regions may be defined by one or more first vertical cut-out regions extending from a bottom of a buccal side toward an occlusal side of the tooth engagement region. The buccal side may be more flexible than the occlusal side so that the detachment region flexes when a removal force to release the palatal expander apparatus from the patient's palate is applied to the detachment region.

Abstract: Palatal expander apparatuses for expanding a patient's palate (“palatal expanders”) and methods of using and making them. The palatal expanders may include tooth engagement regions connected by a palatal region that is configured to apply force between the tooth engagement regions. At least a portion of the palatal region may be configured to have a clearance from the patient's mid-palatal region when the palatal expander is worn by the patient. The clearance between the palatal region and the patient's palate may decrease from the patient's mid-palatal region laterally toward the tooth engagement regions.

Abstract: Described herein are intraoral appliances with adaptive cellular materials and structures to provide enhanced mechanical properties and orthodontic functionality, and related methods. The described appliances may have higher Young's modulus and elongation rate than appliances made from conventional materials. Further, the described appliances may have desirable non-linear force/strain profiles. Additionally, the control provided by using cellular structures allow for increased customization for individual patients. Thus, the described appliances may be more effective, have longer appliance lifetimes and/or provide less discomfort to patients.

Abstract: A trading system for atomically executing a smart contract for trading between a first blockchain and a second blockchain includes a coordinator section and a first user section on the first blockchain and a second user section on the second blockchain. The coordinator section sends a first packet created based on a predetermined transaction in which a contract function is specified to the first and second user sections. When the contract function in the first packet received from the coordinator section is successful, the first user section saves a change operation in a state store associated therewith, acquires lock for a change target, and sends a second packet with a status set executable to the coordinator section. When the execution is failed, the first user section discards the change operation in the state store associated therewith and sends a third packet with the status set inexecutable to the coordinator section.
