COMMENTARY. An alternative method for constructing an obturator prosthesis for a patient with a bilateral cleft lip and palate: a clinical report.

摘要

The authors have expanded upon a previous technique, authored by Tuna and colleagues, that used a fixed partial denture (FPD) to position and stabilize a discontinuous, or free-floating, premaxillary segment in a bilateral cleft lip and palate (BCLP) subject. In the present article, the authors have combined the stabilization purpose of the FPD with a design that incorporates sole retention for a maxillary obturator by the same FPD in a BCLP subject. The original technique1 used a provisional FPD as a guide to reposition and stabilize a discontinuous premaxillary segment in a, BCLP subject. The altered provisional restoration was used as an impression tray to impress the prepared teeth as well as record the new positions for the two maxillary central incisors in the free-floating segment, the maxillary right and left cuspids and second premolars. From the subsequently generated master cast, the final FPD was fabricated, stabilizing the premaxillary segment in its revised orientation.
