Apparatus is described, the apparatus including an oral surgical guide. The oral surgical guide includes an arch portion configured to be placed on a dental arch of a subject; and an extension portion extending from the arch portion, and shaped to define a guide hole. Other applications are also described.

Methods for accommodating dental implants in treatment planning. Methods may include generating a treatment plan to treat a dentition using a series of dental appliances, where a position of a digital implant in a digital dental model is identified. At least one dental appliance of the series of dental appliances may be created, where the at least one dental appliance may be shaped to implement at least one stage of the treatment plan and include an offset portion that is shaped to provide a space between the offset portion and an actual implant to avoid impingement of the at least one dental appliance on the actual implant and allows for osseointegration of the actual implant.

Provided is an orthodontic plate to be fixed to a mandibular ramus, the orthodontic plate including a fixing part implanted into a retromolar fossa portion of a mandible in a mouth, the retromolar fossa portion being near a molar; a hook part connected to the fixing part, and dynamically connected to orthodontic appliances placed at lower teeth for mandibular orthodontics; and a connection part connecting the fixing part and the hook part, the connection part projecting and being sloped from a front end surface including the fixing part toward a front end surface including the hook part, so as to allow the hook part to be positioned without being interrupted by the lower teeth.

The invention discloses a modular surgical bone screw assembly having a threaded base portion and a screw head adapted to attach a variety of structures to bone. The features of the screw include a modular design for the assembly that separates the function of anchorage to the recipient bone to one of the modules of the device (threaded portion) from the other function of attaching another element (such as bone block, membrane, orthodontic wires, elastics etc) to a second module (the screw head). The design also allows the head to be exchanged after the implant has been placed.

A hybrid temporary anchorage device implant system and method of use is disclosed. A temporary anchorage device (TAD) implant includes an external hex head, a cupped inner portion, a threaded core, a platform, and an implant portion. A first abutment is installed on the implant portion. The first abutment may include a graduated portion, a screw-retained healing collar, and a threaded portion. A second abutment may be installed over the first abutment. The second abutment may include a graduated head, a bulbous base, and an inner canal.

The orthodontic assembly is used in a user's mouth to facilitate tooth movement. The orthodontic assembly includes an interchangeable clip member configured to be removably affixed to a frame member such that the clip member engages at least one of the user's teeth. The orthodontic assembly further includes a frame member configured to be removably positioned proximate the lingual portion of user's teeth. The frame member includes a fastening mechanism configured to cooperatively engage the clip member such that the clip member may be removably affixed to the frame member.

The invention relates to orthodontic appliances that simulate the center of resistance in orthodontic treatment. The orthodontic appliance includes at least one bonding pad for attaching said appliance to a corresponding lingual side of a tooth and a netted structure extending in a mesial-distal direction substantially below the at least one bonding pad. The netted structure engages or passes components for delivering force in orthodontic treatment. With aid of the force delivering components engaged or passed in the netted structure, a dentist or a clinician can advantageously simulate the center of resistance in a dentition or a tooth in orthodontic treatment for space closure and/or distalization.

Methods, devices, systems, and series of appliances are provided for dental implant positioning. One method for positioning an implant with dental treatment includes determining an implant location based on a virtual model of an optimized dental occlusion, moving one or more teeth using a first number of a series of dental appliances, from a first orientation to a second orientation, the second orientation exposing the implant location, placing an implant at the exposed implant location using a landmark included in at least one of the series of dental appliances, repositioning one or more teeth using a second number of the series of dental appliances, from the second orientation to a successive orientation.

Systems and methods including expandable dental appliances. The expandable dental appliances may include left and right portions that are distinct and separate parts, and that may be coupled by a sliding expansion feature configured to laterally translate the left and right portions toward or away from each other. Each of the left and right portions may include a palatal region and a tooth engagement region that are customized to respective left and right sides of a patient's upper dental arch. Systems may include multiple non-expandable dental appliances that are configured to be worn sequentially over the patient's upper dental arch to expand the patient's palate over corresponding stages of a treatment plan.

A removable orthodontic assembly to be used in a user's mouth, including: a frame member configured to be removably positioned proximate a lingual portion of the user's teeth; a first connector member, wherein the first connector member comprises a first end extending proximate to a labial portion of the user's teeth and a second end engaging the frame member; and a labial bow configured to be removably positioned proximate to the labial portion of the user's teeth having a first end and a second end, wherein the labial bow is configured to removably engage the first connector member.
