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 ... -

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), ... -
Short implants (<8mm) versus longer implants (≥8mm) with lateral sinus floor augmentation in posterior atrophic maxilla: a meta-analysis of RCT's in humans
(Medicina Oral S.L., 2020)Background: One of the greatest challenges that dentists face today is to rehabilitate severe atrophied alveolar ridges in partially and completely edentulous patients with implants. Despite the high ... -
Influence of the CAD-CAM systems on the marginal accuracy and mechanical properties of dental restorations
(International Journal of Environmental Research and Public Health, 2020)The aim of this study was to compare the quality of different computer-assisted-design and computer assisted manufacturing systems (CAD-CAM) generated by only one scanner, focusing on vertical fit ... -
New bactericide orthodonthic archwire: NiTi with silver nanoparticles
(Metals, 2020)A potential new bactericide treatment for NiTi orthodontic archwires based in the electrodeposition of silver nanoparticles on the surface was studied. Twenty-five archwires were treated by electrodeposition, ... -
