Particular difficulties arise when patient-specific plates (PSPs) are utilized for the fixation of multi-piece LeFort 1 osteotomies. PSPs are, for the most part, extremely accurate and gives the surgeon the ability to transfer the planned virtual movements directly to the patient. The problem is that it is almost impossible to surgically reproduce three-dimensionally the vertical osteotomies. Because of this, bony interferences are created which result in the inability to passively seat the maxillary teeth into the surgical splint. To prevent this, there are three important pearls related to PSP Design, Splint Design and surgical techniques that eliminate this problem.
Learning Objectives:
At the conclusion of this presentation, participants should be able to:
Analyze the problems that can occur when patient specific plates are utilized for multi-piece LeFort 1 osteotomies.
Explain what steps need to be taken in splint and plate design which lessens the creation of bony interferences.
Analyze how to eliminate bony interferences that arise with the use of patient specific plates in multi-piece LeFort 1 osteotomies
