Prevalence of infection with the use of β-tricalcium phosphate as a bone graft substitute during Le Fort I osteotomy

While grafting with bone substitutes has been shown to provide greater stability in maxillary advancements, infection remains a concern with any material that is placed in close proximity to the maxillary sinus. The purpose of this study was to evaluate the prevalence of infection in maxillary advancements in which a bone graft substitute (β-tricalcium phosphate; β-TCP) was placed at the time of surgery. This was a retrospective study of all maxillary osteotomies. Patients were divided into two groups: group 1 included maxillary osteotomies in which β-TCP was not used; group 2 included any maxillary osteotomy where β-TCP was used.
