[Clinical research of rehabilitating bilateral total maxillary defects with a new improved implants and magnetic attachments bar frameworks: report of 9 cases].
OBJECTIVE
The purpose of this study was to research the clinical effects of a new improved implant-magnetic attachment bar framework supported the total maxillary prosthesis.


METHODS
Nine patients underwent tumor resection with defect of bilateral maxilla, and after at least 1 year,4 implants was inserted into their bilateral zygomatics in every patient. A kind of new improved bar framework were fabricated with implants tightly. Based on these bar framework ,total maxillary prostheses were completed finally.


RESULTS
The new improved bar framework was utilized to support the prosthesis, it was observed that the prosthesis was more stable. All patients were satisfied with mastication, speech and appearance after wearing the prosthesis. The prosthesis demonstrated a significant improvement in function and esthetics.


CONCLUSIONS
It is concluded that from the practical point of view,the prosthesis with new bar framework is superior to the previous one, and its clinical prosperity is wide. But further studies are necessary to evaluate its long term effects.
