WebJul 10, 2024 · Objective The aim of the current study was to evaluate the effect of ultraviolet (UV) photofunctionalization of dental titanium implants with exposure to the oral cavity on osseointegration in an animal model. Methods Forty-eight titanium implants (Camlog® Conelog® 4.3 mmx9.0 mm) were placed epicrestally into the edentulous jaws of three … WebPhotofunctionalization results in nearly 100% bone-to-implant contact and three-fold greater mechanical anchorage strength compared to the untreated titanium surfaces in animal models [10,12]. These effects occur because of the removal of carbon compounds (such as hydrocarbons) accumulated on titanium surfaces [ 13 , 14 , 15 ].
WebTitanium disks were acid etched to create micropits on the surface. Micro-nano-hybrid surfaces were created by depositioning 300-nm diameter TiO 2 nodules onto the micropits using a previously established self-assembly protocol. These disks were stored for 8 weeks in the dark to allow sufficient aging, then treated with UV light for 48 hours. WebIntroduction: The UVC-irradiation (“UV-photofunctionalization”) of titanium dental implants has proved to be capable of removing carbon contamination and …
WebAug 1, 2024 · UVC photofunctionalization improved the early osseointegration of aged titanium implants. However, the effect was not dependent on the UVC-light duration within the range from 1/6 hour to 1 hour. Section snippets
