Abstract

Abstract: Purpose: The reliability of dental implant treatments in oral cancer patients remains incompletely defined. The purpose of this study is to retrospectively investigate dental implants in oral cancer patients after jaw resection. Methods: A total of 103 implants had been placed in 23 patients. We examined the clinical factors (gender, age, jaw location, implant position, bone augmentation, radiation therapy, chemotherapy, free flap reconstruction, osseous reconstruction) to predict the probability of implant removals. In addition, we examine about peri-implantitis and prosthetic systems. Results: During the follow-up period, the 2 year survival rate was 91.3%, and the 5 year survival rate was 83.3%. We noted no serious adverse effects like malignant tumor recurrence or osteoradionecrosis from the implant site. Male patients, chemotherapy, and radiation therapy was identified to be significant risk factors associated with implant removals in the univariate analysis, and radiation therapy was identified to be a significant risk factor in the multivariate analysis. There were no significant differences between the each groups of prosthetic systems in implant removals. Free flap reconstruction was not demonstrated to be a significant risk factor for peri-implantitis. Conclusion: The results of this study suggest that radiation therapy was associated with an increased risk of dental implant removals in oral cancer patients after jaw resection.
