A dental appliances and orthodontic appliance systems for accommodating dental implants. The dental appliances may include an offset portion that is configured to provide a space between the offset portion and an implant implanted within a patient's oral cavity or the patient's tissue surrounding the implant, thereby avoiding impingement of the dental appliance on the implant or the patient's tissue surrounding the implant. Dental implants may include, for example, abutments or caps. The dental appliances may be configured to reposition one or more teeth of the patient.

The present invention relates to a system and method for dental implant and restorative services. By locating the key functions at one physical location, dental implant services are efficiently provided to patients. These functions include a treatment coordinator, a direct marketer, a restorative doctor/prosthodontist, a surgeon, an imaging area, and a dental laboratory, Further, services for dentate patients are improved by utilizing advanced dental implant methods and systems. These methods and systems include both model-based services and CT (computed tomography) guided surgery services. Using these services, improved surgical guides for dental implants are constructed.

Disclosed are apparatuses and techniques for distalizing, mesializing and/or expanding teeth in the upper or lower dental arch of a patient's mouth to make room for crowded or protruded teeth located in the anterior arch region to distally/mesially and/or laterally shift into. In some aspects, an apparatus includes a body; a first arm coupled to an adjustment mechanism of the body and attachable to a molar; a second arm coupled to the apparatus body and attachable to a non-molar tooth; and an anchorage device attachable to a bone in the mouth, which the first arm is configured to transfer a force onto the molar when the adjustment mechanism is actuated to cause movement of the molar in the dental arch, and which the anchorage device is operable to positionally stabilize the body and the second arm to prevent movement of the non-molar tooth in the dental arch.

An orthodontic appliance can easily achieve and ensure movement of correction target tooth row in a desired direction and achieve highly predictable treatment is provided while anchorage is satisfactorily ensured. A correction device includes a grip member formed to fit to an inner shape of an oral cavity of a patient so as to grip and cover a tooth row, gum parts, and alveolar bone parts of the patient. The correction device includes a first piece 20 covering an area extending from a crown part to a periphery of a cervical part of a correction target tooth and a second piece included in the grip member. The correction device further includes a force applying member 30 provided to connect the first piece 20 to the second piece 10 and configured to move the correction target tooth in a desired direction.

A processing method and apparatus for ultrafast laser deposition of a multilayer film including a diamond-like carbon film, an anti-reflection film and an anti-fingerprint film includes: generating primary plasma by first excitement on a target material with a femtosecond or picosecond pulsed laser beam as a pre-pulse; and generating secondary plasma by second excitement on the target material under plasma grating, formed by allowing two femtosecond pulsed laser beams to intersect at a small include angle for interaction in the primary plasma, for deposition to coat a film.

The present invention relates to an orthodontic device (1) adapted to fit on the maxilla of a patient, comprising: A) at least one central expander (2) incorporating an expansion screw (4) allowing its expansion and, consequently, that of the patient's maxillary arch (AM), said central expander (2) being attached to: A1) A first symmetrical pair of posterior retention arms (5), each retention arm (5) being coupled to a band (3) of a first pair of bands (3) allowing the device (1) to be fixed on the right and left permanent molars of the patient's maxillary arch (AM), at least one of the bands (3) also constituting the distal element of a distalization set (12) comprising at least two elements, A2) At least one symmetrical pair of anterior retention arms (8), which rest on the palatal surface of the teeth in front of the right and left molars to which the first pair of right and left bands (3) are fixed; A3) A second symmetrical pair of posterior retention arms (6), each retention arm (6) being formed of two distinct segments, with a first segment coupled to a band (3) of the first pair of bands (3) and a second segment coupled to the central expander (2), the first and second segments being connected by a joint (7).

A medical apparatus including a bar with a first attachment loop, a second attachment and a plurality of hooks, wherein the medical apparatus is an arch bar.

Connectors for connecting or linking one instrument or object to one or more other instruments or objects are disclosed herein. In some embodiments, a connector can include a first arm with a first attachment feature for attaching to a first object, such as a surgical access device, and a second arm with a second attachment feature for attaching to a second object, such as a support. The connector can have an unlocked state, in which the position and orientation of the access device can be adjusted relative to the support, and a locked state in which movement of the access device relative to the support is prevented or limited. Locking the connector can also be effective to clamp or otherwise attach the connector to the access device and the support, or said attachment can be independent of the locking of the connector.

An orthodontic alignment device can have a palatal contour anchorage (PCA) feature that generally matches the shape of the patient's hard pallet. This PCA feature may be built slightly off-set to deliberately push against the patient's palate and/or gingiva to provide anchorage support of staged translation of the teeth. By transferring the required anchorage away from the teeth and onto the palate, through the PCA feature, the adjacent teeth are no longer subjected to unwanted side effects of reaction forces.

Systems, methods, devices and apparatus for mandibular advancement or retraction via bone anchoring devices are described herein. In various aspects, an apparatus for treating a patient via mandibular advancement or retraction comprises a plurality of anchoring devices positioned in the patient's intraoral cavity. Each of the plurality of anchoring devices can be positioned in bone of the patient's upper jaw or bone of the patient's lower jaw. One or more connecting structures can be removably coupled to and extend between the plurality of anchoring devices in order to displace the lower jaw anteriorly or posteriorly relative to the upper jaw.
