Minimally Invasive Treatment of an Adult with Severe Pseudo Class III Malocclusion

Pseudo class III malocclusion is reverse anterior occlusion or anterior cross-bite with first molars and canines in a class I relationship. It is very important to diagnose the pseudo class III from true skeletal class III. The combination of anterior displacement of the mandible, tooth wear, and loss of occlusal vertical dimension (OVD) in adults may result anterior cross-bite. The key factor in diagnosis of this malocclusion is an interdisciplinary approach with an orthodontist. Cephalometric images are essential for diagnosis of pseudo class III mal-occlusion. Most relevant publications on correcting this condition have recommended either full-coverage restorations or extraction and placement of implants to correct this malocclusion. Advances of material and technology may help dental practitioners to restore tooth wear and OVD with a conservative approach without removing more tooth structures. This clinical report shows the treatment of pseudo class III with minimally invasive treatment using partial coverage restorations fabricated with lithium disilicate.
