Considering Dental Arch Shape

November 25, 2022

In this brief lecture clip, Dr. Rebecca Bockow shares an interesting perspective on how the bone structure of the upper and lower jaw may affect a patient's tongue posture and airway negatively, even if the teeth appear to be acceptably positioned.

Dr. Rebecca Bockow is a dual-trained board-certified orthodontist and periodontist – one of only a handful in the country. She lectures nationally on periodontics, orthodontics, interdisciplinary orthodontics, airway, and skeletal growth and development.

“So this adult female came to us with a unilateral crossbite, and her maxilla is so narrow that we only can physically fit the smallest MSC that's made, is a six-millimeter MSC.

“So we were able to get that nice sutra opening. So now the sutures are open. But we can't, we've maxed out our expander. So we have to think a little differently here. So anatomically, those sutures are now open, so we should have less resistance to our appliance, and so we went ahead and used the tooth-borne expander.

“We did get some secondary tipping, but we went ahead and widened that upper arch, and you can see once again that nice parallel opening here, and then we were able to finish her up. So before and after expansion... pretty compelling once again doing this non-surgically in an adult.”

Dr. Bockow loves to create beautiful smiles for her patients, setting them up for a lifetime of dental and airway health.
