Periodontal diseases: is it possible to prevent them? A populational and indivi...
COTA,Luís Otávio Miranda; VILLAR,Cristina Cunha; VETTORE,Mario Vianna; CAMPOS,Julya Ribeiro; AMARAL,Guilherme Castro Lima Silva doAbstract Periodontal diseases are infectious inflammatory chronic diseases of a multifactorial nature. They are primarily caused by dysbiotic ecological changes in dental biofilm, which may be influenced by risk factors. The prevention of periodontal diseases may involve different strategies focused on reducing distal, intermediate, and proximal risk factors at both the population and individual levels. Effecti...
Implant-based factor as possible risk for peri-implantitis
ZANDIM-BARCELOS,Daniela Leal; CARVALHO,Gabriel Garcia de; SAPATA,Vitor Marques; VILLAR,Cristina Cunha; HÄMMERLE,Christoph; ROMITO,Giuseppe AlexandreAbstract Peri-implantitis is currently a topic of major interest in implantology. Considered one of the main reasons of late implant failure, there is an emerged concern whether implant characteristics could trigger inflammatory lesion and loss of supporting bone. The purpose of this narrative review is to provide an evidence based overview on the influence of implant-based factors in the occurrence of peri-imp...
Efficacy of stem cells on bone consolidation of distraction osteogenesis in ani...
MORILLO,Carlos Manuel Rubio; SLONIAK,Mariane Cristina; GONÇALVES,Fernanda; VILLAR,Cristina CunhaAbstract Distraction osteogenesis (DO) relies on the recruitment and proliferation of mesenchymal stem cells (MSC) to the target site, where they differentiate into osteoblasts to promote bone formation. Nevertheless, MSC recruitment appears to be slow and limits bone formation in DO defects. Thus, this systematic review aims to evaluate the ability of locally applied MSC to enhance bone formation in DO preclin...

NEUMANN,Eduardo Aloisio Fleck; VILLAR,Cristina Cunha; FRANÇA,Fabiana Mantovani GomesFractured abutment screws may be replaced; however, sometimes, the screw cannot be removed and the entire implant must be surgically removed and replaced. The aim of this study was to compare the fracture resistance of abutment retention screws made of titanium, polyetheretherketone (PEEK) and 30% carbon fiber-reinforced PEEK, using an external hexagonal implant/UCLA-type abutment interface assembly. UCLA-type ...
