Patent number: 9757211Abstract: 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.Type: GrantFiled: August 16, 2016Date of Patent: September 12, 2017Inventor: Robert Ward
