Open bite represents a serious challenge in dentofacial orthopedics. This lecture will describe the dentoskeletal effects produced by different types of appliances for the treatment of dentoskeletal open bite in the mixed dentition (quad helix with crib, open bite Bionator, removable plate with crib, rapid maxillary expansion and vertical pull chin cup). The effects produced by rapid maxillary expansion in prepubertal open bite patients will be also illustrated. The long-term stability of open bite treatment will be analyzed by reporting the results of 2 studies on the effects of quad-helix/crib therapy and rapid maxillary expansion in association with posterior bite blocks in open bite growing patients.
Comprehend the dentoskeletal effects produced by different protocols for the treatment of open bite patients.
Identify that an increased mandibular plane angle is not a contraindication for rapid maxillary expansion.
Identify the long-term dentoskeletal effects produced by quad-helix/crib therapy and rapid maxillary expansion in association with posterior bite blocks in open bite growing patients.
