Introdução: O objetivo deste trabalho é aprofundar o conhecimento da doença peri-implantar e os tratamentos existentes descritos na literatura. Material e método: Revisão bibliográfica das doenças peri-implantares, com base em uma pesquisa nos indexadores Pubmed, Medline e Cochrane Library, utilizando os uni termos " peri-implantite, mucosite, dependência de tabaco, microbiota oral, sobrecarga oclusal, tratamento cirúrgico, terapia antimicrobiana, desintoxicação,  terapia regenerativa, defeitos ósseos ". Desenvolvimento e discussão: Análise de fatores de risco, diagnóstico e tratamento de doenças peri-implantares. Conclusões: Fatores como tabaco ou histórico de periodontite, juntamente com falta de higiene bucal, são as principais causas da doença peri-implantar. Um diagnóstico correto da etiologia, bem como a escolha apropriada da terapêutica, pode interromper o avanço da doença peri-implantar. Após o tratamento realizado, será muito importante o monitoramento e manutenção regulares da higiene bucal adequada.

It is already established in the clinical routine of oral rehabilitation the inclusion of osseointegrated implants. The search for this type of treatment has become popular and, with it, maintenance problems should be well studied and treated by professionals in this area. It is unlikely that many of these patients who are candidates for implant treatment were not victims of any periodontal disease. In rehabilitation planning, in some situations, failures may occur soon after implant placement or later, when the implant is already osseointegrated. These failures are generally related to bacterial contamination both during surgery and subsequent colonization of these pathogens in the periimplant region. This article aims to conduct a survey of the current medical literature on the installation of implants in patients with a history of periodontal disease. As a methodology, Scopus, Web of Science and Google Scholar indexing portals were scanned with the terms implantodontics, periodontics and periodontal diseases. A total of 9,876 articles were found and 25 articles were selected considering the relevance or impact factor of the journals where these articles were published. It is concluded that there is a direct relationship between dental implant loss and periodontal disease.

The dental surgeon often performs treatment in hypertensive patients and should therefore be aware of the diagnosis of the disease, its signs and symptoms and treatment. Thus, the aim of this study was to perform a literature review on dental treatment in patients with hypertension. The bibliographic survey consists of articles available in databases such as Scielo, Pubmed and Google Scholar, published from 1995 to 2016. Most patients who attend dental offices have high blood pressure, although some are unaware of their condition, making the measurement of blood pressure of all patients by the professionals is essential. In the treatment of these patients it is important to know the previous medical history, the antihypertensive drugs used and the expectations (fear, anxiety, tension, stress) regarding the proposed treatment. It was concluded that dental treatment of hypertensive patients represents a challenge for dental surgeons, who should be scientifically based in order to establish the best conduct for the management of this type of patient. Perform a very detailed anamnesis and blood pressure measurement, guide the patient about his systemic condition, Clarifying the therapies employed and recognizing the changes arising from them are fundamental for establishing the best treatment plan and for minimizing or preventing complications that may occur during dental care.

Traction required for removal of cemented cast crown copings in dental implant abutments. AbstractIntroduction: Implant-supported fixed prostheses are alternative treatments increasingly common in dental clinics. They can be screwed or cemented depending on the surgical planning. Screwed prostheses are reversible, have greater bacterial infiltrate, aesthetics impaired by the screw hole. Cemented prostheses have reversal difficulties, loss of the prosthesis in case of screw loosening and better aesthetics due to the lack of screw hole. Objectives:In this context, the present study aims to evaluate the tensile strength levels of cemented copping´s by 2 different types of cement for fixation of cemented implantsupported crowns.Methodology: Three specimens were made with implants and crowns cemented with different materials, where each of these specimens was submitted to a traction test.Results: Zinc phosphate cemented copping's (CP1 and CP4) required a tensile strength of 118.02 N and 213.63 N respectively, while resin cemented copping's (C2 and C3) required a tensile strength of 258.93 N and 228.87 N respectively. Conclusion:Within the limitations of the current in vitro conditions employed in this study, retention of cemented crown copping's in the resin abutment and zinc phosphate cement implant abutments was significantly affected by the cement type. Resin cement required significantly higher tensile strength than zinc phosphate cement for removal of copipngs.
