Clinical and radiographic outcomes of zirconia dental implants - a clinical case series study
(MDPI, 2022)
The purpose of this clinical series was to evaluate the clinical and radiographic outcomes of 20 zirconia dental implants, with a minimum follow-up of two years. Patients with at least one zirconia ...
Color stability of CAD/CAM interim material for long-term fixed dental prostheses vs. conventional materials after immersion in different staining solutions
(MDPI, 2021)
The color stability of interim computer-aided design and computer-assisted manufacturing (CAD/CAM) materials has not been exhaustively investigated. The aim of this study was to compare the translucency ...
Ion release from dental implants, prosthetic abutments and crowns under physiological and acidic conditions
(MDPI, 2021)
Ion release from dental implants and prosthetic restoration can affect osteointegration and implant viability over a long period of time. Therefore, the aim of this study was to study the ion release ...
Clinical and radiographic features of external cervical resorption: an observational study
(Wiley, 2023)
Aim: To determine the prevalence of symptoms, clinical signs and radiographic presentation of external cervical resorption (ECR). Methodology: This study involved 215 ECR lesions in 194 patients referred ...
Discerning the subfibrillar structure of mineralized collagen fibrils: a model for the ultrastructure of bone
(Public Library of Science, 2013)
Biomineralization templated by organic molecules to produce inorganic-organic nanocomposites is a fascinating example of nature using bottom-up strategies at nanoscale to accomplish highly ordered ...
Functional signatures of ex-vivo dental caries onset
(Taylor & Francis Group, 2022)
Background: The etiology of dental caries remains poorly understood. With the advent of next-generation sequencing, a number of studies have focused on the microbial ecology of the disease. However, ...
Guiding bone formation using semi-onlay calcium phosphate implants in an ovine calvarial model
(John Wiley & Sons, 2022)
The restoration of cranio-maxillofacial deformities often requires complex reconstructive surgery in a challenging anatomical region, with abnormal soft tissue structures and bony deficits. In this ...
Correlación entre el patrón de erupción de la dentición definitiva y la predominancia de la lateralidad de la función motriz: un estudio transversal
(Elsevier, 2021)
Objetivos: Evaluar si el orden de la erupción dental es un buen indicador de la lateralidad motora. Métodos: Estudio transversal en escolares de ambos sexos de 6 a 8 años tratados mediante las revisiones ...
Fatigue of narrow dental implants: influence of the hardening method
(MDPI, 2020)
The use of narrow titanium dental implants (NDI) for small ridges, reduced interdental space, or missing lateral incisors can be a viable option when compared to the conventional wider dental implants. ...
The role of hardness and roughness on the wear of different CoCrMo counterfaces on UHMWPE for artificial joints
(Springer, 2011)
Wear tests were carried out to study the effect of the hardness and roughness with various counterface materials on UHMWPE wear behaviour. The materials used as counterfaces were based on varieties of ...
