Dimensional change in maxillary prosthetic obturators.
Dimensional stability of obturator bases and changes in occlusal relationships are areas of clinical importance in the oral rehabilitation of maxillectomy patients. The dimensional change in maxillary prosthetic obturators constructed with three different denture base resins was investigated. The results indicate that a light-polymerized material had the least percent of change between base and teeth positions.
