Evaluation of the peri-implant epithelial tissue of percutaneous implant abutments supporting maxillofacial prostheses.

The use of commercially pure titanium endosseous implants has become state-of-the-art treatment for patients with craniofacial defects. This study defined criteria that can be used in assessing the peri-implant abutment epithelium. The criteria were then used to examine overall tissue reaction.
