Jack is a patient who was referred by a local periodontist as a possible All-on-4 case. Jack was aware of his severe dental problems but wanted to avoid losing all of his teeth if possible. He was mainly concerned with function (he wants things to look natural). With this case, you will see that Jack has severe occlusal issues along with airway issues and facial profile/symmetry issues. You will learn how to handle the occlusal challenges that a severe wear case with a deep overbite can present. You will also learn why obtaining accurate records and a verified CR bite registration is crucial when treatment planning these cases.
