Abstract: An orthodontic bracket has a base configured for attachment to a tooth surface, a bracket element with an arch wire slot attached to one side of the base, and a clip for securing the arch wire in the slot. The bracket element has a wall portion extending upward along one side of the arch wire slot. This wall portion has three indentations in a line parallel to the mesiodistal direction. There is a channel running entirely through the bracket element underneath the arch wire slot. The clip is substantially U-shaped and has three parallel protrusions shaped to fit within the three indentations of the wall portion, and a locking element. The clip is securable to the bracket by placing the clip through the channel and engaging the locking element onto the bracket element, and placing the protrusions into the indentations of the bracket element.

Abstract: A radiographic guide that can be used as a surgical guide is provided. The radiographic guide uses a provisional dental implant instead of a denture tooth or a custom made diagnostic tooth. The provisional dental implant, which can be integrated or selectively interconnected to the radiographic guide, may have a through-hole or a tapped hole that facilitates location of a dental implant. If the planned implant location is acceptable, the radiographic guide can be used as a surgical guide, wherein the hole guides surgical tools used to modify a patient's maxilla or jaw so it can receive the implant.

Abstract: An orthodontic direct bonding stent facilitates ideal positioning of physical attachments on a patient's teeth. Novel designs of direct bonding stents include uniquely configured windows for guiding placement of the attachments. Windows of reduced depth leave a majority of each attachment exposed beyond the stent for easy grip and manipulation, and use of a reduced height wall opposite the window-equipped wall eases removal of the stent without disruption of the adhered attachments. Use of elastomeric material at the window boundaries provides an improved seal with the tool for less adhesive splay, and inter-arch stents enable maxillary and mandibular placement with a single appliance. Lingual windows enable lingual placement of attachments for reduced visibility, and reduced wall thickness between adjacent windows provides improved mesial access to attachments.
