In order to fix a POB, you must see WHY and then apply the appropriate solution. I look at 3 previous refinements to show what happened and how to set up the ClinCheck to finally fix it.
Malpositioned teeth aren't always a malocclusion that *needs* to be corrected. Many molar crossbites are functional and damage isn't seen to the teeth nor the periodontium. Also in this case, the POB was a bigger concern.
