Decision points

What to notice before deciding

Tooth Position Versus Jaw Relationship

Growth Status

Growth status is one of the practical factors that can change diagnosis, appliance choice, treatment timing or the way progress is monitored. It should be discussed in the context of the whole case rather than treated as an isolated checklist item.

Severity And Functional Effects

Severity and functional effects is one of the practical factors that can change diagnosis, appliance choice, treatment timing or the way progress is monitored. It should be discussed in the context of the whole case rather than treated as an isolated checklist item.

Whether Surgery Is Relevant

Whether surgery is relevant is one of the practical factors that can change diagnosis, appliance choice, treatment timing or the way progress is monitored. It should be discussed in the context of the whole case rather than treated as an isolated checklist item.
