TLDR
The implants placement before RT showed better results compared with the implants performed after RT, suggesting that DIs in head and neck cancer patients must be placed before RT or simultaneously during ablative tumor surgery.Abstract:
Introduction:The aim of this study was to compare the osseointegration and the survival of dental implants (DIs) immediately placed in postextraction sites, in mandibles of minipigs that underwent radiotherapy (RT).Materials and Methods:Twelve Brazilian minipigs were divided into the following groupread more

The dose-dependent impact of γ-radiation reinforced with backscatter from titanium on primary human osteoblasts
TL;DR: In this article , the effects of ionizing radiation on human osteoblasts (hOBs) were investigated, and they were seeded on machined titanium, moderately rough fluoride-modified titanium, and tissue culture polystyrene, and cultured in growth- or osteoblastic differentiation medium (DM).

Two-stage implant placement technique for the management of irradiated jaws: An animal study.
TL;DR: Within the limitations of this animal study, the 2‐stage implant placement technique could be used to reduce trauma in irradiated bone and to improve wound healing around dental implants.

Osteoradionecrosis: A new concept of its pathophysiology
TL;DR: The classic sequence in the pathogenesis of osteoradionecrosis of the jaws has been accepted as radiation, trauma, and infection, but a new one more accurately describing the biochemical and cellular pathology is offered.

Robert E. Marx,Robert P. Johnson +1 more
TL;DR: Clinical guidelines for the management of irradiated patients with osteoradionecrosis include a recommendation for deferring radiation treatment for 21 days after tissue wounding, if possible; a relative contraindication to wounding tissue during a radiation course; a recommend for the use of hyperbaric oxygen before wounding; and a strong recommendation to provide comprehensive dental care to the irradiated patient.
