Case 4 Maxillary extractions, immediate implant placement, immediate loading, and complete nonremovable zirconia restoration with pink porcelain 237

Case 5 Mandibular implant bar–supported full removable denture converted to a nonremovable restoration to improve comfort of the neutral zone and phonetics 240

Chapter 9 Orthognathics 245

Case 1 Severe anterior open bite corrected with maxillary-only orthognathics and occlusal therapy with upper incisor restorations 246
