The areas of maximum stress were the intact primary palate region, inferior orbital foramen of the non-cleft and the cleft sides, and the zygomatic buttress of the cleft side. During expansion, the intact primary palate showed high stress and acted as a region of major resistance, followed by the zygomatic buttress on the cleft side.<\/jats:p>\n        <\/jats:sec>\n        <jats:sec>\n          <jats:title>Conclusions:<\/jats:title>\n          <jats:p>Clinicians should consider a need for customization of expansion therapy for cleft patients depending on the patient's age, the type of cleft present (primary or secondary palate), and the desired area of expansion (anterior or posterior).<\/jats:p>\n        <\/jats:sec>","DOI":"10.2319\/070110-367.1","type":"journal-article","created":{"date-parts":[[2011,2,7]],"date-time":"2011-02-07T15:46:16Z","timestamp":1297093576000},"page":"503-509","source":"Crossref","is-referenced-by-count":20,"title":["Biomechanical response of the maxillofacial skeleton to transpalatal orthopedic force in a unilateral palatal cleft"],"prefix":"10.2319","volume":"81","author":[{"given":"Pawan","family":"Gautam","sequence":"first","affiliation":[{"name":"Postdoctoral, Craniofacial and Skeletal Diseases Branch, NIDCR\/NIH, Bethesda, Md"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Linping","family":"Zhao","sequence":"additional","affiliation":[{"name":"Research Director, Craniofacial Center (MC 588), University of Illinois at Chicago, Chicago, Ill"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pravin","family":"Patel","sequence":"additional","affiliation":[{"name":"Associate Professor, Craniofacial Surgery, Craniofacial Center (MC 588), University of Illinois at Chicago, Chicago, Ill"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1164","reference":[{"key":"i0003-3219-81-3-503-b01","series-title":"Am J Orthod Dentofacial Orthop","first-page":"569","article-title":"Skeletal and dental changes in the sagittal, vertical, and transverse dimensions after rapid palatal expansion.","volume":"126","author":"Chung, C.
