The use of the mandibular ramus for alveolar reconstruction in oral implantology

Bone grafts are widely used in alveolar ridge augmentations to allow correct implant installations. Intraoral donor sites, such as the maxillary tuberosity, symphysis and mandibular ramus have presented good characteristics and outcomes; however, the mandibular ramus has comparative advantages that promo...

Root length and alveolar bone level of impacted canines and adjacent teeth after orthodontic traction: a long-term evaluation

J. appl. oral sci; 25 (1), 2017
Abstract Objective The aim of this retrospective study was to evaluate the long-term effects of orthodontic traction on root length and alveolar bone level in impacted canines and adjacent teeth. Material and Methods Sample consisted of 16 patients (nine males and seven females), mean initial age 11 ...

Avaliação clínica e radiográfica de implantes curtos: estudo retrospectivo no período de 7 anos

Áreas edêntulas com severa reabsorção óssea têm sido reabilitadas com próteses fixas instaladas sobre implantes curtos, evitando que os pacientes sejam submetidos a cirurgias de reconstrução óssea. Este estudo retrospectivo descreve o comportamento de implantes curtos avaliados em um período d...

Influência de drogas quimioterápicas na evolução da periodontite experimental em ratos

Objetivo: Este estudo avaliou comparativamente a influência dos quimioterápicos 5-fluotouracil (5-FU) e Cisplanina (CIS) para tratamento de câncer no periodonto saudável, sobre a evolução da periodontite experimental (PE) e as funções hepáticas e renais de ratos portadores de PE submetidos ao tr...

Effects of platelet-rich fibrin on healing of intra-bony defects treated with anorganic bovine bone mineral

Abstract Anorganic bovine bone mineral (ABBM) is extensively used in the treatment of intra-bony defects. Platelet-rich fibrin (PRF) is a new-generation platelet concentrate with a simplified technique. Although certain studies have reported the use of PRF in the treatment of intra-bony defects, to date,...

Suppressor of cytokine signaling 1 expression during LPS-induced inflammation and bone loss in rats

Abstract This study aimed to characterize the dynamics of suppressor of cytokine signaling (SOCS1) expression in a rat model of lipopolysaccharide-induced periodontitis. Wistar rats in the experimental groups were injected three times/week with LPS from Escherichia coli on the palatal aspect of the first...

Different engagement of TLR2 and TLR4 in Porphyromonas gingivalis vs. ligature-induced periodontal bone loss

Abstract This study was conducted to investigate the roles of different Toll-like receptor (TLR) signaling in Porphyromonas gingivalis (P. gingivalis)-induced and ligature-induced experimental periodontal bone resorption in mice. Wild-type (WT), TLR2 knockout (KO), TLR4KO, and TLR2&4 KO mice with C57...
