What should be done FIRST before placing implants in this patient?

Occlusal plane rehabilitation Before implant placement, the occlusal plane must be restored. Otherwise, placing implants under a supra-erupted opposing tooth would create improper crown height space, occlusal interferences, and overloading. Intrusion with ortho, enameloplasty, crown reduction, or RCT with crown-shortening may be needed first.
