RESUMO

El propósito de este reporte es describir el tratamiento no quirúrgico y quirúrgico en una paciente con múltiples implantes con peri-implantitis. Inflamación, sangrado espontáneo, supuración y pérdida ósea fueron los signos clínicos y radiográficos observados en los 21 implantes presentes en su boca. Las profundidades al sondaje oscilaban entre 5 y 15 mm. Se llevó a cabo la terapia no quirúrgica asociada a antibióticos sistémicos (Metronidazol 500 mg) y antiséptico (Clorhexidina 0,12%) con la finalidad de reducir los signos de inflamación y sangrado. Durante la re-evaluación se colocaron gránulos de Minociclina de liberación controlada en las bolsas residuales. Los sitios que no respondieron fueron abordados quirúrgicamente, realizando además la implantoplastia de las espiras que quedaron expuestas al medio bucal. Uno de los implantes debió ser explantado. A los 9 meses, no presentaba signos de inflamación peri-implantar, sangrado al sondaje ni pérdida ósea progresiva.

The aim of this report is to describe the non-surgical and surgical treatment of a patient with multiple implants with peri-implantitis. Inflammation, spontaneous bleeding, suppuration and bone loss were the clinical and radiographic signs observed in the 21 implants present in her mouth. Probing depths ranged from 5 to 15 mm. Non-surgical therapy with systemic antibiotics (Metronidazole 500 mg) and antiseptic (Chlorhexidine 0.12%) was carried out in order to reduce the signs of inflammation and bleeding. During re-evaluation, controlled-release minocycline granules were placed in the residual pockets. The sites that did not respond were approached surgically. Also, the implantoplasty of the threads that were exposed to the oral environment was performed. One of the implants had to be explanted. At 9 months, there were no signs of peri-implant inflammation, bleeding on probing or progressive bone loss.

RESUMO

A Osteomielite dos Maxilares (OM) é uma inflamação óssea, de origem na maioria infecciosa, podendo atingir a porção medular e cortical dos ossos maxilares. Apresenta-se em maior extensão na mandíbula, devido ao pobre suprimento sanguíneo que essa possui, sendo mais prevalente em homens entre a faixa etária de 40 a 60 anos. Sua etiologia está relacionada principalmente às infecções odontogênicas, infecções secundárias e corpos estranhos ocasionais, como os implantes dentários. Tem-se por objetivo apresentar um relato de caso clínico sobre OM na região posterior da mandíbula, bem como sua associação a uma insatisfatória implantação dentária onde houve desenvolvimento de lesão peri-implantar. Paciente do gênero feminino, 53 anos, melanoderma, apresentou dor crônica, abaulamento ósseo sem outros sinais significativos na região de molares inferiores no lado direito, radiograficamente visualizava-se imagem mista sendo sugestiva de sequestro ósseo. Na história pregressa relatou ter realizado explantação na referida região após ser diagnosticada com peri implantite. Ao final do estudo concluiu-se que a afecção teve como causa a infecção bacteriana proveniente de contaminação durante a inserção de implante dentário. Optou-se por remoção cirúrgica do osso necrótico e inflamado... (AU)

Osteomyelitis of the Jaws (OM) is a bone inflammation, of mostly infectious origin, which can affect the medullary and cortical portion of the maxillary bones. It presents itself to a greater extent in the mandible, due to the poor blood supply that it has, being more prevalent in men between the age group of 40 to 60 years. Its etiology is mainly related to odontogenic infections, secondary infections and occasional foreign bodies, such as dental implants. The objective is to present a clinical case report on OM in the posterior region of the mandible, as well as its association with an unsatisfactory dental implantation, where there was development of a peri-implant lesion. Female patient, 53 years old, melanoderma, presented chronic pain, bone bulging without other significant signs in the region of lower molars on the right side, radiographically a mixed image was visualized, suggesting bone sequestration. In her previous history, she reported having performed explantation in that region after being diagnosed with peri-implantitis. At the end of the study, it was concluded that the disease was caused by bacterial infection from contamination during dental implant insertion. We opted for surgical removal of the necrotic and inflamed bone... (AU)

La osteomielitis de los maxilares (OM) es una inflamación de los huesos, en su mayoría de origen infeccioso, que puede afectar la porción medular y cortical de los huesos maxilares. Se presenta en mayor medida en la mandíbula, debido a la escasa irrigación sanguínea que tiene, siendo más prevalente en hombres entre el grupo de edad de 40 a 60 años. Su etiología se relaciona principalmente con infecciones odontogénicas, infecciones secundarias y cuerpos extraños ocasionales, como los implantes dentales. El objetivo es presentar un reporte de caso de OM en la región posterior de la mandíbula, así como su asociación con una implantación dentaria insatisfactoria a partir de la cual desarrollamos una lesión periimplantaria. Paciente femenina, 53 años, melanodermia, presenta dolor crónico, tumefacción ósea con otros signos significativos en región molar inferior del lado derecho, radiográficamente se visualiza imagen mixta sugestiva de pérdida ósea. En su historia previa menciona haber realizado una explantación en esa región tras ser diagnosticada de periimplantitis. Al final del estudio, se concluyó que la enfermedad fue causada por una infección bacteriana provocada por la contaminación durante la inserción del implante dental. Se optó por la extirpación quirúrgica de la piel necrótica e inflamada... (AU)

RESUMO

Objetivos: avaliar se a união entre implantes e/ou a presença de gengiva artifi cial infl uencia no sangramento a sondagem dos tecidos peri-implantares. Material e métodos: foram incluídos pacientes tratados com implantes de titânio (Implacil De Bortoli, São Paulo, Brasil), instalados no período de 1998 a 2012, na Universidade de São Paulo (USP). Os implantes foram examinados para avaliação do sangramento a sondagem, sendo divididos de acordo com o tipo de prótese: unitárias (n=167), parciais (n=522) e totais (n=227); e de acordo com a ausência (n=674) ou presença (n=242) de gengiva artifi cial. O teste estatístico com equação de estimativa generalizada foi usado para testar possíveis associações. Resultados: foram examinados 183 pacientes reabilitados com 916 implantes em função, pelo menos por um ano. Ao menos um ponto de sangramento a sondagem foi detectado em 85 (50,9%), 304 (58,2%) e 129 (56,8%) implantes das próteses unitárias, parciais e totais, respectivamente. Em relação à gengiva artificial, 378 (56,1%) dos implantes sem e 140 (57,9%) dos implantes com esta característica apresentaram sangramento a sondagem. Não foram verificadas diferenças significativas entre os grupos. Conclusão: a união dos implantes ou a presença de gengiva artificial não foram associadas com os resultados de sangramento a sondagem nos implantes em função.

Objective: to evaluate whether the prosthesis type (single, partial, complete) and/or the presence of artifi cial gingiva can influence on bleeding on probing of peri-implant tissues. Material and methods: patients treated with titanium dental implants (Implacil De Bortoli, São Paulo, Brazil) between 1998 to 2012 at the University of Sao Paulo (USP) were included in this study. The implants were divided according the following prosthodontic types: single (n=167), partial (n=522), and complete (n=277), and also regarding the presence (n=674) or absence (n=242) or artificial gingiva. The generalized estimating equation test was used to verify possible associations. Results: 183 patients and 916 implants at least 1 year in function were screened. At least one bleeding point was detected in 85 (50.9%), 304 (58.2%), and 129 (56.8%) implants for single, partial, and complete prostheses, respectively. 378 (56.1%) and 140 (57.9%) implant from groups without and with artificial gingiva presented bleeding on probing. No significant differences were identified among groups. Conclusion: the prosthesis design and/or artifi cial gingiva were not associated to bleeding on probing for dental implants in function.

RESUMO

BACKGROUND: The aim of this systematic review is to evaluate the long-term outcomes of patients with periodontitis submitted to periodontal therapy/maintenance and implant placement. METHODS: Studies reporting clinical and/or long-term implant outcomes from partially edentulous patients with periodontitis who were treated and followed periodontal maintenance for ≥5 years were considered eligible for the review. Screening of the articles, data extraction, and quality assessment were conducted independently and in duplicate. RESULTS: Search of MEDLINE, EMBASE, and CENTRAL databases resulted in 959 papers, and of them 931 were excluded after title/abstract assessment. The full texts of 28 potentially eligible publications were screened, but only 10 studies met inclusion criteria. Most of the included studies (77.8%) presented a medium/high methodologic quality. The results demonstrated that patients with a diagnosis of periodontitis had satisfactory implant outcomes. Implant survival was high (92.1%) within studies reporting 10 years of follow-up. Parameters related to probing depth, clinical attachment level, and bone loss around teeth increased the occurrence of peri-implantitis and implant loss. Non-attendance to periodontal maintenance and smoking habits were also associated with less favorable implant outcomes. CONCLUSIONS: This systematic review confirmed that implant therapy can be successfully used in patients with a diagnosis of periodontitis who underwent proper therapy and regular periodontal maintenance. Residual pockets, non-attendance to the periodontal maintenance program, and smoking were considered to be negative factors for the long-term implant outcomes.
