Background

The 5-year survival rate for cancer of the head and neck remains at about 50% to 60%, making this a major health concern. With early detection and correct treatment, cure rates and quality of life may be improved. Radiotherapy is often an essential part of the therapeutic plan and has been associated with reduced anatomic structure and physiologic functioning. Dental rehabilitation after head and neck cancer treatment, especially if radiotherapy has been used, can be highly challenging.

Methods

Thirty-one articles were chosen for review, although overall, the quality and level of evidence was low. A total of 1814 patients received 8177 implants, with 1989 in control groups and inserted in a non-irradiated jaw. Mean follow-up was 56 months, with a range of 3 to 120 months. For the meta-analyses, three studies were used for 1990-2006 and four for 2007-2013. Two studies were used for a meta-analysis of implant survival based on bone origin.

Results

Analysis of the studies showed no significant difference in implant survival between the irradiated and non-irradiated jaws. Meta-analysis of the literature covering 1990 and 2006 revealed a significant difference in implant survival between the irradiated and non-irradiated jaws, but more current reviews indicated implants successfully integrated into bone and remained functionally stable long-term in irradiated jaws. Mean implant survival rate for all studies was 83%, with a range from 33.96%

Discussion

The implant survival data for irradiated and non-irradiated native bone were comparable. This indicates that patients who have undergone radiation in the head and neck region can be successfully managed with dental implants. Grafted bone for these patients may have a compromised survival, however.

Clinical Significance

Recent changes in treatment for patients who have undergone irradiation to the head and neck may have improved the outcomes of implant therapy. Three-dimensional planning, guided
