Surface comparison of three different commercial custom-made titanium meshes produced by SLM for dental applications
(Materials, 2020)The use of individualized titanium meshes has been referred to in scientific literature since 2011. There are many advantages to its use, however, the main complications are related to early or late ... -
Polyethylene glycol pulsed electrodeposition for the development of antifouling coatings on titanium
(Coatings, 2020)Titanium dental implants are widely used for the replacement of damaged teeth. However, bacterial infections at the interface between soft tissues and the implant can impair the functionality of the ... -
Effect of temperature on the orthodontic clinical applications of NiTi closed-coil springs
(Medicina Oral, Patologia Oral y Cirugia Bucal, 2013-07-01)NiTi spring coils were used to obtain large deformation under a constant force. The device consists on a NiTi coil spring, superelastic at body temperature, in order to have a stress plateau during the ... -
Accuracy of implant casts generated with conventional and digital impressions: an In vitro study
(International Journal of Environmental Research and Public Health, 2018)Purpose: The aim of this study was to compare the accuracy of digital dental impressions with the accuracy of impressions obtained via conventional techniques. Methods: Two different master models were ... -
Two different strategies to enhance osseointegration in porous titanium: inorganic thermo-chemical treatment versus organic coating by peptide adsorption
(International Journal of Molecular Sciences, 2018)In this study, highly-interconnected porous titanium implants were produced by powder sintering with different porous diameters and open interconnectivity. The actual foams were produced using high cost ... -
Antibacterial properties of triethoxysilylpropyl succinic anhydride silane (TESPSA) on titanium dental implants
(Polymers, 2020)Infections related to dental implants are a common complication that can ultimately lead to implant failure, and thereby carries significant health and economic costs. In order to ward off these infections, ... -
