A dental restorative device is shown as comprising a first cured or hardened layer in the form of an occlusal surface of the tooth being restored and a second uncured dental composite layer joined to the first layer enabling a dental professional to perform direct dental restoration procedures with results replicating indirect direct dental restoration procedures. A system comprising the multi-layered dental restorative device and packaging provides for sufficient support and protection of the uncured second layer and facilitates positioning and finishing of the dental restorative device by cooling the uncured portions to a rigid state while in the packaging, positioning the dental restorative device, and modifying the second layer to fit, curing the second layer and permanently placing the fully cured and hardened dental crown on the tooth being restored.

Methods of administering a quantity of adhesive to bond orthodontic brackets is disclosed herein. The quantity of adhesive to bond a selected bracket to a tooth at a specific location thereon can be calculated based on a known geometry of the selected bracket and a digital model of the patient's teeth. A instruction guide can visually indicate with a graphic the amount of adhesive to dispense from a syringe or other device to bond the selected bracket to the surface of the tooth at a specific location planned in the digital model.

A package (10, 10) for securing an orthodontic bracket (30) includes a pocket (12, 71) having an inclined floor (40, 70) and a mechanical locking device (51, 71) for removably holding the bracket (30) in the pocket (12, 71) until it is intentionally removed by a user.

Packaged orthodontic assemblies include a chamber, an orthodontic appliance, and a support structure engaged with the appliance to secure the appliance in the chamber. The support structure can include a post complemental to a partially enclosed passage, typically an arch wire slot, in the appliance body. The support may orient the wall sections of the enclosed passage at an acute angle relative to a chamber side wall.

Provided are a denture base material package capable of improving operation efficiency while securing quality, without being influenced by an operator's skill level, in the production of a denture by a production method for a denture involving using a reference denture, and a production method for a denture involving using the same. A denture base material package includes: a string-shaped molded body obtained by molding a photocurable denture base material having plastic deformability into a string shape; and a light-shielding member having an internal space kept airtight, and accommodating the string-shaped molded body in the internal space. The light-shielding member includes (i) a tray having a groove for accommodating the string-shaped molded body, and (ii) at least one kind of member selected from the group consisting of: a bag body configured to house the tray thereinside; and a lid member configured to seal an opening of the groove.

A dental powder/liquid material-containing preparation accommodation bag, which suppresses entrainment of air in mixing a powder material and a liquid material for dispensing, is provided. A powder material 8 is accommodated in a powder material accommodation chamber 3 of a bag body 2, while a liquid material 9 dissolving the powder material 8 and changing into a pasty form, in cooperation with the powder material 8 is accommodated in a liquid material accommodation chamber 4 partitioned from the powder material accommodation chamber 3 by a weakened section 7. The weakened section 7 is ruptured by applying a pressing force to the bag body 2. As a result, the powder material accommodation chamber 3 and the liquid material accommodation chamber 4 communicate, to feed the liquid material accommodated in the liquid material accommodation chamber 4 into the powder material accommodation chamber 3. Then, the powder material 8 and the liquid material 9 changing into the pasty form are pressed within the powder material accommodation chamber 3 from the surfaces of the bag body 2 for dispensing.

Provided packaged orthodontic assemblies and methods compressively retain an orthodontic appliance in a container along opposing sides of the appliance adjacent the bonding surfaces of its base. This can be done using a mechanism that limits contact between the appliance and the container while accommodating a substantial range of transverse base dimensions. This engagement mechanism allows an adhesive-coated appliance to be retained in a consistent orientation for convenient dispensing, while limiting potentially adverse interactions between the adhesive and the container. By avoiding loss of the adhesive components during storage, these assemblies and methods can extend shelf life and provide consistent adhesive handling properties.

The present application is directed to a method of using a hardenable dental article. The method can include providing the hardenable dental article; applying the hardenable dental article to a dental structure; customizing the shape of the hardenable dental article; and at least partially curing the hardenable dental article.
