Sinus lift technique and dental implants for rehabilitation for a Down syndrome patient with tomographic 3-years follow-up.

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.

Tratamento químico, mecânico e cirúrgico-regenerativo da peri-implantite: relato de caso clínico com nove meses de acompanhamento em um sítio mandibular posterior extenso / Chemical, mechanical, and surgical-regenerative treatment of peri-implantitis: a case report with nine months of follow-up in a large posterior mandibular site

A peri-implantite é caracterizada como uma lesão inflamatória localizada nos tecidos peri-implantares, sendo considerada uma das causas de perda tardia de implantes. O tratamento cirúrgico da peri-implantite abrange uma grande variedade de técnicas, diversos biomateriais para preenchimento dos defeitos ósseos e numerosos métodos dedescontaminação de superfícies. O debridamento aberto para descontaminação da superfície foi a abordagem mais utilizada e se mostrou mais efetivo para a resolução da peri-implantite, quando comparado ao debridamento fechado. Contudo, os resultados encontrados na literatura são controversos. Assim, outros estudos devem ser conduzidos, visando elucidar quais são as estratégias mais efetivas para o tratamento desta patologia. O objetivo deste estudo foi realizar uma revisão de literatura sobre o tratamento da peri-implantite, bem como apresentar um relato de caso clínico, no qual foi utilizada a regeneração óssea guiada para reconstrução das condições anatômicas perdidas.

Peri-implant diseases are characterized by local inflammatory lesions affecting the hard and soft tissues around an osteointegrated implant. It can be considered one of the major causes of late implant loss. Proposed treatments include surgical management, biomaterials, and numerous decontamination methods. The open debridement for decontamination of the surface was the technique most used and it was more effective for the resolution of peri-implantitis when compared to close debridement. However, some results are controversial. Further studies must be performed in order to describe effective and viable strategies to treat peri-implantitis. Therefore, the aim of this study was to review the pertinent literature and and to present a case report where GBR procedures were used to reconstruct the lack of anatomi­cal conditions.
