Survival of dental implants in native and grafted bone in irradiated head and neck cancer patients: A retrospective analysis

Abstract

There was no significant difference in survival when implants were placed in native or grafted bone in irradiated head and neck cancer patients. For implants placed in native bone, survival was significantly influenced by the location of the implant (maxilla or mandible, anterior or posterior).

Maxillary and mandible contouring in patients with a head and neck area irradiation

“…more delayed failures [15][16][17]. Dose distribution in the different part of the bone can obviously explain these differences.…”

Dental Implants Installed in Irradiated Jaws

“…Granstrom et al (1994) found an increased rate of implant loss in irradiated subjects compared with nonirradiated ones. Conversely, Buddula et al (2011) reported high success rates of implants placed in grafted (98.1%) and native (100.0%) mandibular bones over a 3-year period. Moreover, 2 publications using animal models have shown that implant stability during osseointegration may be impaired in irradiated jaws because of the decrease in bone vascularity and vitality (Verdonck et al, 2008b); however, in the short term, the bone mineral density seems to be similar to that of nonirradiated alveolar bone (Verdonck et al, 2008a).…”

Assessment of the survival of dental implants in irradiated jaws following treatment of oral cancer: A retrospective study

“…[51314151617] Animal experimentation models also show rate of failure of dental implants under similar conditions. [181920] In the present scenario, there are no strict criteria about the success or failure of dental implants in irradiated jaws of cancer treated patients, therefore, we evaluated retrospectively, the clinical outcome of dental implants in a series of patients.…”
