Cross Arch stabilization for Adult Cleft Palate patient?

Last Updated August 22, 2018
Reviewed By:  Dr. Dale Gerke

I have a 72 year old male patient with a failing full arch fixed partial denture as a result of extensive caries of natural tooth abutments. His cleft palate was repaired many years ago, but the right and left sides of his maxilla are not united and there is soft tissue closure. Patient was edentulated and six implants placed with a treatment plan for a maxillary bar overdenture. The question is whether or not to connect the right and left sides of the maxilla rigidly with a full arch bar or have two separate bars? Another option might be to have separate conical abutments (Atlantis Conus-Dentsply) and have a metallic “bar” incorporated into the denture that would provide cross arch stabilization. Any literature out there that examines this question? The opposing dentition is a full arch fixed partial denture on natural teeth.
