Complicações na reabilitação bucal com implantes osseointegravéis

The oral rehabilitation now has a powerful ally: the dental implants. There is no denying the importance of the implant within the context of dental practice. Initially indicated for the rehabilitation of fully edentulous patients, now has gained growing space, with indications for partial edentulism, multiple unit, with high predictability of success in esthetic restorations, combined with the techniques of manipulation of soft tissues, and guided tissue regenerationearly prosthetic loading. But like any dental procedure, whether surgical or medical implantology is also subject to the occurrence of failures and complications. This paper aims to provide a review of the literature for discussion of these complications, their causes, their managements and proservation.

Condições de saúde de pacientes do gênero feminino com dependência química

This study evaluated the general and oral health conditions of female patients included in a program for recovering drug addiction and patients who did not use drugs. By means of anamnesis and medical history, as well as medical and dental assessments, the health conditions of 160 patients were assessed; 80 presented drug dependence and 80 do not use drugs. The most frequently used drugs were tobacco, alcohol, and crack, usually in associations. The patients presenting chemical dependence had increased frequency of behavioral changes, as well as several diseases involving the immune and cardiovascular systems, detaching infectious and inflammatory reactions and delay in the process of tissue repair. In the oral cavity, it was verified a high occurrence of periodontitis and gingivitis. Chemical dependence showed to be associated to a high frequency of infections, arthritis, hypertension and behavioral changes, which normally would not be noted by health professionals, but that could compromise the results of medical and dental treatments.

Ocorrência de microrganismos periodontopatogênicos em pacientes com dependência química

Drug addiction won dramatic aspects in terms of its dimensions and the effects that it imposes. These chemical agents are able to reduce the immune reactivity and tissue repair, and enhance microbial aggression, aggravating the destruction of the periodontium and other side effects. This study aimed to evaluate the presence of key periodontal pathogens in the mouth of drug addiction patients, comparing it with individuals who do not exhibit this dependence, as well as assess the influence of oral conditions on the occurrence of such microorganisms. For this purpose, data on systemic health conditions, socioeconomic, patterns of licit or illicit drug consumption of 100 patients with chemical dependency kept in rehabilitation clinics and an equal number of non-dependent patients, who formed the control group were obtained. Intra and extraoral clinical examinations were performed and samples of supragingival and subgingival biofilm, saliva and mucous membranes were collected. The presence of the targeted microorganism was assessed by polymerase chain reaction (PCR). It was found that Porphyromonas gingivalis, Tannerella forsythia, and Treponema denticola showed close correlation with bone loss and gingival bleeding in drug addiction dependents and control group, but the oral mucous membranes and saliva of addicts showed higher occurrence of these pathogens.

Avaliação da biocompatibilidade de implantes de silicone gel em subcutâneo de ratos: estudo histomorfométrico

Objective: Histomorphometric study to evaluate the biological tissue compatibility of silicone implants suitable for plastic surgery. Methods: Thirty Wistar white rats received subcutaneous implants ande the revestiment of silicone gel Silimed, and randomized into six groups of five animals each, according to the type of implanted material and the time of sacrifice. Eight areas of 60.11 mm2 corresponding to the obtained surgical pieces were analyzed, counting mesenchymal cells, eosinophils, and foreign body giant cells, observing an acceptable biocompatibility in all implants, for subsequent statistical analysis by Tukey test. Results: Silicone gel showed inflammation slightly greater than for other groups, with tissue reactions varying from light to moderate, whose result was the formation of a fibrous capsule around the material, recognized by the organism as a foreign body. Conclusion: In general, it is possible to affirm that silicone gel had acceptable levels of biocompatibility, confirmed the rare presence of foreign body giant cells, and when of the rupture, formed a fibrous capsule around the material, separating the material of the organism.

Reabilitação de maxila atrófica com tecido ósseo homógeno e prótese fixa implantossuportada

The techniques of bone reconstruction for atrophic maxillae have been improved in order to promote bone tissue growth in both height and thickness. The grafts performed with use of autogenous bone is considered the gold standard by most researchers, for demonstrating osteogenic capacity and not to promote antigenic response. However, this type of grafting is not possible to get bone tissue in large quantity for extensive renovations. In recent years, alternatives have been researched to overcome the limitations of autogenous bone. Several alternatives have been investigated to supply the disadvantages of autogenous bone grafts. In such studies, allogeneic bone grafts which are obtained from individuals with different genetic load, but from the same species have been extensively used. They can be indicated in cases of arthrosplasty, surgical knee reconstruction, and large bone defects as well as in oral and maxillofacial reconstruction. Besides showing great applicability and biocompatibility, this type of bone is available in unlimited quantities. To rehabilitate atrophic maxillae an option that has been performed with high success rate is the reconstruction with bone graft followed by osseointegrated dental implants to rehabilitate the patient aesthetics and functionally. This paper aims to show the feasibility of allogenic bone as material for reconstruction of atrophic maxilla, and subsequent rehabilitation with metal ceramic fixed prosthesis implant and dental restoration with accompanying three years through literature review and clinical case report.
