Diastemas: How to Manage Margins

About This Case

A longtime restorative patient. Narrow arch. Undersized anteriors. Invisalign already in progress. Halfway through treatment, the picture changed — a deviated septum, a maxilla that wasn’t sitting right, and a Bolton discrepancy that couldn’t be solved restoratively. Dr. Seay and orthodontist Dr. Katie Bullwinkel walk through the mid-treatment MARPE decision, the expansion numbers, and a prepless veneer-plus-composite hybrid that finished the case without touching a single virgin tooth.
