Down Syndrome or trisomy 21 (T21) is a genetic condition caused by the presence of an extra chromosome in pair 21 and is related to a high prevalence of agenesis of permanent teeth and periodontal alterations that may be associated to the loss of permanent teeth at early ages. With the increase in life expectancy of people with T21 in the last decades, it is necessary to expand the knowledge to offer possibilities of treatment with dental implants, aiming to serve this aging population.
Aims: The aim of this article is to report a surgical procedure of sinus lift to enable the installation of dental implants in the posterior region of the maxilla.
Methods and results: A 50 year-old patient with T21 was rehabilitated with implants, simultaneously with sinus lift surgery, by the lateral window technique, using xenogenous bone graft and fibrin-rich plasma. After 1 year, the patient was rehabilitated with prosthetics on implants.
Conclusion: The feasibility of this technique in patients with Down syndrome could be observed, after 3 years of follow up, with favorable clinical results.
