Abstract
Patients with a history of cancer are increasingly common in the dental office. Treating cancer patients requires a multidisciplinary team, which should include the dentist, in order to control the complications that occur in the oral cavity and also to recover the patient undergoing treatment in any of its types: surgical, medical, radiotherapeutic, or its possible combinations. Dental implants can be a safe and predictable treatment option for prosthetic rehabilitation. The aim of this paper is to describe in retrospect the success rate of osseointegrated implants in oncology and non-oncology patients placed by the Master of Dentistry in Oncology and Immunocompromised Patients, as well as the Master of Medicine, Surgery and Oral Implantology of the University of Barcelona Dental Hospital, between July 2011 and March 2016. 466 patients were reviewed, with a total of 1405 implants placed, considering the oncological history of the patients and the implant success rate. The total success rate in the concerned period was 96.65%. When comparing cancer patients with healthy ones, the success rate has been 93.02% in the first case, and 97.16% in the latter. According to the literature review, our results encourage implant placement in cancer patients, it is important to recognize that this is an analysis of a complex care pathway with a large number of confounding variables. However, the findings should not be considered as generalizable.
Highlights
According to the World Health Organization, cancer is the between first or second leading cause of death worldwide (1,2)
The medical records of the patients submitted to the placement of dental implants performed by the Master in Dentistry in Oncology and Immunocompromised Patients and the Master in Medicine, Surgery and Oral Implantology of the University of Barcelona Dental Hospital between July 2011 to March 2016 were reviewed, considering as research variables: history of head and neck cancer, history of cancer in other parts of the body, the type of treatment given, and data related to implant survival in case of loss, depending on the time in which it occurred
This paper presents the implant survival rates in a large head and neck cancer patient cohort at a regional treatment center
Summary
According to the World Health Organization, cancer is the between first or second leading cause of death worldwide (1,2). In 2018, there were about 18 million new cases and 9.6 million related deaths (2). The body can be affected by more than one hundred different types of cancer. The use of tobacco is the most relevant and controllable risk factor; it is the cause of more than 20% of cancerrelated deaths in general and 70% in the case of lung cancer, according to the World Cancer Report in 2014. The development of cancer related to tobacco use depends on the susceptibility of different tissues and organs. In the oral cavity, tobacco produces a direct harmful action, while the effect on other organs (such as the lung, for example) is related to the participation of active metabolites. The risk of smoking patients having oral cancer is 5 to 20 times higher than non-smoking one (1,3,4)
