[Functional rehabilitation of irradiated maxillary bones (author's transl)].

The teeth should be conserved before radiotherapy: --in patients with good buccodental hygiene the teeth are conserved and fluoride treatment instituted,--when hygiene is only moderate, the mandibular teeth outside of the treated area are left in place and fluoride treatment is also attempted. The crowns are conserved, and an attempt is even made in some cases to apply them, as for example on the canines.--when hygiene is inexistant, all the teeth are extracted. Following radiotherapy, the authors will restore a prosthesis two months after irradiation in long-standing edentulons patients, and after 6 months for patients who have recently become edentulons. They sometimes recommend conservative treatment and a fixed prosthesis when the social context is favourable.
