Oral rehabilitation with dental implants after cancer treatment

Abstract

Background: Patients who undergo surgical management of oral cancer may greatly benefit from an implant-supported prosthesis. This study reports on the clinical experience of dental implant placement in patients following resection of oral cancer over a 15-year period. Controversies including the use of dental implants in irradiated tissues, and hyperbaric oxygen treatment will also be discussed. Methods: Thirty-one patients who had dental implants placed as part of their oral rehabilitation between 1992 and 2007 were investigated. Demographic data and factors including implant survival, type of prosthesis provided, radiotherapy and the hyperbaric oxygen therapy were analysed. Results: In this retrospective study, there was a retention rate of 110 implants from a total of 115 implants placed. A high rate of implant retention was found, with 5 implant failures from a total of 115 implants placed. The 5 failed implants occurred in free flap bone that had been irradiated. Conclusions: Dental implants provide an important role in the oral rehabilitation of oral cancer patients. There may be an increased risk of implant failure in free flap bone that has been irradiated.

Prothèse complète amovible obturatrice implanto-retenue : présentation d’un cas

“…Mais ce résultat est plus aléatoire dès lors que les patients sont édentés complets. Les implants sont de plus en plus proposés dans le traitement des pertes de substance étendues [4,5,6]. Ils convient néanmoins de bien sélectionner les patients éligibles qui, dans le contexte de radiothérapie et de chimiothérapie, ont des risques majorés de complications parfois graves même si la radiothérapie ne constitue plus une contre-indication absolue à la mise en place d'implants.…”

Integrative review on oral cancer

“…6 The quality of life of patients with oral cancer is impaired, given that some surgical procedures necessary to remove the tumor may lead to a significant disability, including facial deformity, loss of hard and soft tissue, impaired speech, swallowing and chewing. 33 These complications have a significant impact on the functions of the patient, including the basic need to eat, drink or speak. Pain is also often associated with these oral complications and can lead to increased need for narcotics, increased hospital stay and increased risk of death for systemic infections.…”

Intérêt de l’utilisation de l’oxygénothérapie hyperbare en prévention de l’échec implantaire chez le patient irradié

“…Dès 1998, Esposito et al affirmaient qu'il ne fallait pas considérer l'irradiation d'un site osseux comme étant une contre-indication à la mise en place d'implant dentaire [32], avis largement partagé depuis cette date [33][34][35]. Dans une brochure intitulée « la reconstruction du visage après un cancer », éditée récemment par la Ligue contre le cancer à destination du grand public, il est fait mention de la possibilité de mise en place d'implants dentaires, notamment pour stabiliser un dispositif prothétique [97].…”
