ABSTRACT

Abstract The aim of this study was to evaluate the effects of adjunct systemic antibiotic treatment with metronidazole (MTZ) and amoxicillin (AMX) in patients receiving non-surgical subgingival debridement (NSD) for peri-implantitis. Forty subjects presenting with at least one implant with severe peri-implantitis were randomized into an experimental group [treated with NSD plus MTZ (400 mg) and AMX (500 mg) three times a day for 14 days] and a control group treated with NSD plus placebo. Clinical parameters and submucosal biofilm profiles were evaluated up to 1 year post-treatment. Overall, both treatments improved clinical parameters over time. At 1 year, mean probing depth (PD), mean clinical attachment (CA) level and proportions of red complex pathogens did not differ significantly between the two groups. In addition, mean PD and CA changes to 1-year posttreatment did not differ significantly between the two groups between baseline and 1-year post-treatment. These results suggest that the addition of MTZ and AMX to the treatment protocol of patients undergoing NSD for with severe peri-implantitis does not improve the clinical and microbiological outcomes of NSD. The fact that half of the implants in both groups did not achieve clinical success (PD < 5 mm, no BoP, no bone loss) suggest that neither of the tested protocols were effective for treating severe peri-implantitis.

ABSTRACT

A maxila atrófica anterior é um desafio na reabilitação estético-funcional em pacientes que perderam os dentes por traumatismos dentoalveolares, exodontias na infância, patologias e agenesias, resultando em deficiências horizontais e verticais, necessitando de regeneração óssea. O objetivo deste artigo foi relatar, em um caso clínico, a possibilidade de se utilizar o remanescente do nivelamento ósseo realizado na mandíbula em um enxerto de espessura na região de pré-maxila e posteriormente instalar dois implantes em um único estágio. Diminuindo assim o número de intervenções cirúrgicas


The atrophic maxilla is a challenge earlier in the functional aesthetic rehabilitation for patients who have lost teeth by: dento alveolar trauma, tooth extractions in childhood, disease and tooth agenesis, resulting in horizontal and vertical deficiencies, requiring bone regeneration. The objective of this paper is to report on a clinical case the possibility to use the remaining leveling performed in the jaw bone as a graft thickness in the region of the premaxilla and later install two implants in a single stage, thereby reducing the number of surgical interventions

ABSTRACT

A reabilitação oral por meio da instalação de implantes dentários é um procedimento frequente na clínica odontológica, porém, falhas no planejamento podem levar a casos em que o implante, apesar de osseointegrado, não apresente condições funcionais e estéticas satisfatórias, devido ao seu mau posicionamento tridimensional. Este artigo relata um caso clínico de paciente insatisfeita com o resultado final da prótese devido ao mau posicionamento do implante. Foi realizada a técnica de distração osteogênica, associada à técnica de osteotomia segmentada, utilizando-se um distrator modificado tipo Be Flash, reposicionando o implante tridimensionalmente de forma correta


The oral rehabilitation by dental implants is a common procedure in dental practice, but failure on planning can lead to cases where the implant, even though osseointegrated, has no satisfactory functional and aesthetic conditions due to its malpositioning in three dimensions. This case report shows a dissatisfied patient with the final implant result due to 3D malpositioning. Distraction osteogenesis (Be Flash) along with segmented osteotomie was applied to repositioning the implant in a proper relationship

ABSTRACT

Fundamentado em duas premissas, a saber: a) a posição do implante deve ser rigorosamente compatível com a reabilitação protética; b) o planejamento prévio e a exata transferência transoperatória são as chaves do sucesso em Implantodontia; este estudo buscou o emprego de imagens obtidas por tomografia computadorizada e a possibilidade de posicionar os implantes dentro do campo virtual 3D, e transferir essa resolução para o campo real através de cirurgia guiada. Apresentamos uma proposta de carga imediata com o uso de uma barra segmentada pré-fundida adaptada sobre os implantes colocados com cirurgia guiada.


Based on two premises: a) that the implant should be strictly compatible with the prosthetic rehabilitation and b) preplanning and intraoperative exact transfer are the keys to success, this study used computerized tomography images for placing implants inside the virtual 3-D plane, while transferring this resolution to the real scenario through a guided-surgery procedure. We propose the use of a precast segmented bar for immediate loading, adapted on the implants placed with guided surgery.

ABSTRACT

Vários estudos longitudinais têm reportado uma alta taxa de sucesso da utilização de implantes osseointegrados no tratamento reabilitador. Entretanto, outras investigações têm mostrado a perda de implantes osseointegrados por causa de infecções periimplantares ou trauma oclusal. A periimplantite é caracterizada pela presença de reações inflamatórias que afetam o tecido periimplantar sob função. Indivíduos portadores de periimplantes são colonizados por patógenos periodontais como Porphyromonas gingivalis, Tannerella forsythia, Fusobacterium nucleatum e Treponema denticola, enquanto sítios periimplantares sadios são colonizados por cocos Gram-positivos.


Longitudinal studies have reported a high success rate for rehabilitating treatment through the use of osseointegrated implants. However, other studies have reported osseointegrated implant failure due to peri-implant infections or occlusal overload. Peri-implantitis is characterized by the presence of inflammatory reactions that affect the peri-implant tissue under loading. Subjects with peri-implantitis harbor periodontal pathogens such as Porphyromonas gingivalis, Tannerella forsythia, Fusobacterium nucleatum and Treponema denticola while healthy peri-implant sites harbor cocos Gram-positives.
