Abstract

PURPOSE: To determine if bioactive glass, originally designed for craniomaxillofacial use, can be used effectively for re-pegging of hydroxyapatite orbital implants. METHODS: Over a 2-year period, 3 patients with pegged hydroxyapatite orbital implants and related complications that did not respond to conservative treatment, underwent removal of the implant pegs and/or sleeves. Peg tracts were subsequently filled with bioactive glass. RESULTS: No complications occurred in any case during 3 years of follow-up. After 2 months, 2 patients underwent successful re-drilling of the peg site and insertion of titanium pegs. Both patients were satisfied with the results. The third patient has deferred re-pegging at this time. CONCLUSION: Bioactive glass is effective for refilling old peg tracts and allowing timely re-pegging of hydroxyapatite implants.
