This patient fractured 2 PFM implant crowns and presented with a 6mm healing abutment before seeking treatment with me. His surgeon placed the #19 implant too distal, essentially causing a mesial cantilever within this molar. Rather than make him a third crown we decided to create a long lasting prototype he could wear for a few months to diagnose the occlusal interference causing the failures. I also reduced the buccal-lingual dimension to reduce occlusal forces and eliminate mesial contact entirely. Additionally, this prototype needed to re-create papilla as it had flattened after wearing the healing abutment for several months. Will be tracking patient monthly for 4 to 6 months and create new definitive restoration once comfortable the occlusion is successfully managed. Update Feb 2018 - this patient finally received his final crown; after a few months without incident, my prototype was removed from the implant was duplicated in pressed eMax and delivered to a happy patient.
