title: Investigation of maxillary preprosthetic situations after oral tumor treatment.
abstract: In order to investigate the maxillary preprosthetic situation after oral tumor treatment and/or reconstructive surgery, based on the review of case history and the clinical records 47 cases were analyzed after oral tumor treatment and/or reconstruction, including residual maxillary bone, intermaxillary relationships, defection of maxilla and oral situation after radiation therapy. The results showed that the residual maxillary bone was useful for implantation in the front alveolar bone and zygoma area. The maxillary preprosthetic situation after tumor treatment and/or reconstructive surgery was difficult due to maxillary resection, intermaxillary relationships, unsuitable soft and hard tissue transfer and the irradiation. It is suggested that the maxillary preprosthetic situation after oral tumor treatment is getting worse not only due to maxillary resection and/or irradiation, but surprisingly also due to mandibular resection and/or irradiation.
