A dental attachment placement device comprises a plurality of articulated registration elements shaped for placement on a plurality of teeth, which can facilitate placement, accommodate tooth movement, and improve alignment of the registration elements with the teeth, so as to accurately position an attachment for placement. The plurality of registration elements may comprise one or more attachment supports and one or more retention supports extending from the plurality of registration elements. A dental attachment can be removably coupled to the attachment support. The plurality of registration elements and attachment supports may be located on opposing sides of one or more teeth in order to maintain placement prior to adhering the attachment to the tooth. In some embodiments, each of the plurality of registration elements comprises a tooth registration surface shaped to engage the tooth with a specific position and orientation for accurate positioning of the attachment.

A method for forming dental appliance having an ornamental indicia carrier may include forming a polymeric shell, forming a first adhesive layer configured to be adhered to the polymeric shell, the first adhesive layer including a pressure sensitive adhesive layer, forming a first adhesion layer over the first adhesive layer, and applying a colorant between the first adhesion layer and the pressure sensitive adhesive layer.

Flexible 3D printed orthodontic device with attachment supports

A series of a palatal expanders increasing width can be used to gradually expand a patient's palate. Each palatal expander may have a palatal region flanked by teeth regions. The palatal region can have a plurality of anchor-receiving features (e.g., anchor interfaces) that allow the palatal expander to be attached to temporary anchorage device anchors that have been implanted into the patient's maxilla.

Systems and methods including palatal expanders with anchor interfaces

Series of apparatuses for expanding a patient's palate ('palatal expanders'), including rapid palatal expanders, wherein a left tooth engagement region and a right tooth engagement region are configured to add anti-tipping torque to at least one tooth. Left and right tooth engagement regions may include lingual surfaces with at least one lingual protrusion. Left and right tooth engagement regions may have buccally rotated cavities.

Palatal expanders for controlling crown tipping

A series of palatal expanders and methods of designing palatal expanders, including rapid palatal expanders, where outer occlusal surfaces of a palatal expander are shaped to conform to a geometry of corresponding teeth surfaces of the patient's lower jaw to provide occlusion between occlusal surfaces and the corresponding teeth surfaces.

Palatal expanders and methods of designing palatal expanders

Palatal expander systems and methods. A palatal expander includes a palatal region connecting tooth engagement regions, where the palatal region is configured to apply a lateral force across a patient's palate when the tooth engagement regions are worn over the patient's teeth. Attachment regions on buccal sides of the tooth engagement regions are shaped and sized to engage with dental attachments bonded to the patient's teeth. At least one breach region corresponding to a thinned region of the palatal expander extends anteriorly to posteriorly in the palatal region or an occlusal portion of one or both of the tooth engagement regions. The at least one breach region is configured to breach or bend when a pulling force is applied to one or both of the tooth engagement regions such that one or both of the attachment regions are detached from respective attachments.

Palatal expanders with breach regions

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.

Palatal expanders and methods of expanding a palate

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.

Palatal expanders and methods of forming the same

The present disclosure relates to ornamental indicia carrier and method of producing the same. In some embodiments, the ornamental indicia carrier comprises an ultraviolet light ('UV') cured ink printed on a thin flexible film and combined with an adhesive layer. The ornamental indicia carrier is capable of enduring the conditions inside the mouth for an extended period of time and can be used in conjunction with a dental appliance.

Systems and methods including palatal expanders with anchor-receiving features

Methods for designing and fabrication of a series of apparatuses for expanding a patient's palate ('palatal expanders'). In particular, described herein are methods and apparatuses for forming palatal expanders, including rapid palatal expanders, as well as series of palatal expanders formed as described herein and apparatuses for designing and fabricating them.

Methods and apparatuses for customizing a rapid palatal expander

Releasable and removable palatal expander apparatuses for expanding a patient's palate ('palatal expanders') and methods of using and making them. These releasable palatal expanders are adapted for ease in removal by the patient or caregiver, and may include a breach region configured to predictably bend or break when a pulling force is applied. The palatal expander apparatuses described herein may include one or more locks for locking the palatal expander onto the patient's teeth. The lock(s) may be unlocked to release the palatal expander from the teeth. A lock may include a control for manually unlocking the lock. Unlocking the locks may allow the palatal expander to automatically disengage from the patient's teeth.

Releasable palatal expanders

Dental retainer devices are provided. The dental retainer devices can be customized based on patient specific dental anatomy and dental treatment plans. Methods of making the dental retainer devices are also provided. The methods can included additive manufacturing. Methods are also provided for customization of a dental retainer device based on the patient specific anatomy. The methods for customization can include providing a dentist with different options for anterior teeth coverage, posterior teeth coverage, and palatal configurations for the dental retainer devices.
