Two right\u2010sided contralateral maxillary implants and three mandibular implants were retained.

According to the RT treatment plan, the estimated radiation dose was 61.7\u2009Gy at the contralateral maxillary implant sites and 29.2\u2009Gy at the mandibular implant sites. The patient later developed an unrelated supraglottic squamous cell carcinoma treated with RT; the retained implants remained clinically stable.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This case suggests that clinically healthy pre\u2010existing implants may not require routine explantation before adjuvant RT, even when implant\u2010site radiation exposure is substantial.
