en جراحی دهان، فک و صورت Oral and Maxillofacial Surgery گزارش مورد case report The rehabilitation of heavily abraded occlusion in patients with parafunctional habits is a restorative challenge to the dentist. Use of all-ceramic systems in such cases is widely considered, but uncertainty over their resistance hinders their broad use. The authors would like to illustrate a possible approach by mixing two all-ceramic systems based on zirconium dioxide and lithium disilicate. A 48-year-old female patient attended with reduced vertical dimension in a full dentition. She suffered from craniomandibular (CMD) pain and desired an esthetic rehabilitation. Prosthodontic treatment was started in a pain-free condition, after correction of the vertical dimension with an occlusal splint, over four months. Determination of the treatment was based on the clinical fi ndings: IPS e.max® ZirCAD frameworks veneered with IPS e.max® Ceram were used for discolored retainers or subgingival fi nishing lines. All the rest received IPS e.max® Press crowns. A zirconiia-based, single-tooth-retained distal cantilever reconstruction was used to replace a missing second molar. No technical or biological complication was observed 24 months after treatment. The patient was highly satisfi ed and pain-free. <hr><p> <strong>Source: </strong>Dental Research Journal</p><p> <a href="http://drj.mui.ac.ir/index.php/drj/article/view/1392" target="_blank"><font color="#0000cc">Full Text</font></a></p> Computer-aided design/computer-aided manufacturing, cerec, multilink, relyX Unicem 0 0 http://idai.ir/browse.php?a_code=A-10-32-1184&slc_lang=en&sid=1 Usama N.
