Effect of the nature of the particles released from bone level dental implants: physicochemical and biological characterization
(Coatings, 2022)The placement of bone–level dental implants can lead to the detachment of particles in the surrounding tissues due to friction with the cortical bone. In this study, 60 bone–level dental implants were ... -
Use of porous titanium trabecular as a bone defect regenerator: in vivo study
(Metals, 2022)The application of porous materials is increasingly being used in orthopaedic surgery due to its good results. Bone growth within the pores results in excellent mechanical fixation with the bone, as ... -
Influence of static navigation technique on the accuracy of autotransplanted teeth in surgically created sockets
(Journal of Clinical Medicine, 2022)The aim of this study was to analyse and compare the position of single-rooted autotransplanted teeth using computer-aided SNT drilling and conventional freehand (FT) drilling, by comparing the planned ... -
Benefits of residual aluminum oxide for sand blasting titanium dental implants: osseointegration and bactericidal effects
(Materials, 2022)Objectives. The purpose of this work was to determine the influence of residual alumina after sand blasting treatment in titanium dental implants. This paper studied the effect of alumina on physico-chemical ... -
Oral health conditions and self-reported presence of pain in rowers: an epidemiology study
(Revista Brasileira de Medicina do Esporte, 2021)Introduction: Rowers are especially prone to oral health problems due to the massive consumption of supplements and isotonic drinks that lead eating disorders, due to the need for weight control, and ... -
Fracture resistance in non-vital teeth: absence of interproximal ferrule and influence of preparation depth in CAD/CAM endocrown overlays - an in vitro study
(Materials, 2022)There is ample evidence to support the use of endocrowns to restore endodontic teeth. However, the influence of the position of the interproximal margins on fracture strength has not yet been studied. ... -
Citric acid in the passivation of titanium dental implants: corrosion resistance and bactericide behavior
(Materials, 2022)The passivation of titanium dental implants is performed in order to clean the surface and obtain a thin layer of protective oxide (TiO2) on the surface of the material in order to improve its behavior ... -
Characteristics of particles and debris released after implantoplasty: a comparative study
(Materials, 2022)Titanium particles embedded on peri-implant tissues are associated with a variety of detrimental effects. Given that the characteristics of these detached fragments (size, concentration, etc.) dictate ... -
