(Biomaterials Synthesis and Characterization, 2016)The aim of this work is to describe and compare mechanical properties of eight widely used nickel–titanium orthodontic wires under uniform testing conditions and to determine the influence of the heat ... -
One-step liquid phase polymerization of HEMA by atmospheric-pressure plasma discharges for Ti dental implants
(Applied Sciences, 2021)Dental implants can fail due to various factors, in which bad tissue integration is believed to have a significant role. Specific properties of the implant surface, such as its chemistry and roughness, ... -
Ion release from dental implants, prosthetic abutments and crowns under physiological and acidic conditions
(Coatings, 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 ... -
Effects of different undersizing site preparations on implant stability
(International Journal of Environmental Research and Public Health, 2020)As immediate loading protocols are becoming more frequent, the primary stability of implants has become an essential criterion for the osseointegration of dental implants. Based on this, the objective ... -
Influence of connection type and platform diameter on titanium dental implants fatigue: non-axial loading cyclic test analysis
(International Journal of Environmental Research and Public Health, 2020)Two-pieces dental implants must provide stability of the implant-abutment-interface. The connection type and platform diameter could influence the biomechanical resistance and stress distribution. This ... -
One abutment one time: a multicenter, prospective, controlled, randomized study
(International Journal of Environmental Research and Public Health, 2020)Aim: (PRIMARY) Assess the changes in bone level (6 and 12 months after implant placement) between the test (definitive abutment (DEF)) and control (healing abutment (HEA)) groups. (SECONDARY) Assess the ... -
Evaluation of endovenous sedation using BIS monitoring in dentistry. A systematic review
(Medicina Oral, Patologia Oral y Cirugia Bucal, 2020)Background: The aim of the present review was evaluate the utility and validity of the Bispectral Index (BIS) in dental treatment carried out under endovenous sedation, and compare its efficacy with ... -
A non-interventional study documenting use and success of tissue level implants
(International Journal of Environmental Research and Public Health, 2020)Numerous randomised controlled multicentric studies have investigated various responses to different treatment modalities with dental implants. These studies do not always show the results of daily ... -
Influence of implant design and under-preparation of the implant site on implant primary stability: an In vitro study
(International Journal of Environmental Research and Public Health, 2020)The aim of this study was to evaluate the effects of different implant sites an under-preparation sequence associated with two different implant designs on implant primary stability measured by two ... -
Corrosion resistance and ion release of dental prosthesis of CoCr obtained by CAD-CAM milling, casting and laser sintering
(Metals, 2020)Corrosion resistance and ion release behavior have been evaluated for thirty dental restoration samples obtained by three different manufacturing systems: computer-aided design and manufacturing (CAD-CAM), ... -
