An initial aligner sequence can bring substantial improvement while leaving a detail that needs further assessment. A tooth may not have followed the planned movement closely, a contact may feel different, or the final appearance may need discussion. Invisalign refinements use additional aligners when further movement is appropriate. They are part of clinical decision-making rather than an automatic response to every difference between a preview and a smile.
At Cookstown Dental Centre, the review starts with what has actually changed, what remains, and how the teeth meet. We compare those findings with the agreed goal and discuss whether another stage would offer a useful benefit. Sometimes further movement is recommended; sometimes observation, another approach, or retention is the more appropriate next step. The reasons should be clear before additional treatment begins.
