[sup][9] Xerostomia, pain, burning sensation, dysphagia, slurred speech, and related symptoms can cause discomfort, while accelerated dental caries may contribute to more serious complications such as osteoradionecrosis.

In addition, previous studies have shown that titanium can cause a backscatter effect, which may increase the risk of local overdoses around the plate and contribute to screw loosening, osteoradionecrosis, and wound breakdown [17, 18].
In fact, osteoradionecrosis (ORN) is not a common complication of radiotherapy, and the incidence in the literature has been reported to range from 1% to 37.5% [61].
Osteoradionecrosis of bones within the radiation field (most commonly the mandible) may occur as a result of damage to the bone vasculature and osteocytes and is one of the most serious complications of radiotherapy [19].
Misdiagnosis may include alveolar osteitis, osteomyelitis and osteoradionecrosis, and symptoms may mimic sinusitis, gingivitis/periodontitis, periapical pathology and temporomandibular joint disorder.
