Magnesium–silver alloys are of high interest for the use as temporary bone implants due to their antibacterial properties in addition biocompatibility and biodegradability. Thin wires particular can be used scaffolding, but determination degradation rate homogeneity using traditional methods is difficult. Therefore, we have employed 3D imaging X-ray near-field holotomography with sub-micrometer...

Prosthodontic rehabilitation of a patient with an atrophic edentulous mandible presents a significant challenge in restoring esthetics and function. The purpose of this clinical report is to describe fracture of an atrophic edentulous mandible opposing maxillary natural dentition in association with endosseous dental implants. The patient received two wide-diameter implants in the anterior mand...

PURPOSE The aim of this study was to evaluate the influence of the crown-to-implant (C/I) ratio on the change in marginal bone level around the implant and to determine the site-related factors influencing the relationship between the C/I ratio and periimplant marginal bone loss. METHODS A total of 259 implants from 175 patients were evaluated at a mean follow-up of five years. Implants were ...

Gyárfás conjectured in 2011 that every r-edge-colored K n contains a monochromatic component of bounded (“perhaps three”) diameter on at least ∕ ( r − 1 ) vertices. Letzter proved this conjecture with four. In note we improve the result case = 3: We show 3-edge-coloring either there is most three 2 vertices or color class spanning and has

PURPOSE The aim of this retrospective study is to analyze the relationship between local factors and survival rate of dental implant which had been installed and restored in Seoul Veterans Hospital dental center for past 10 years. And when the relationship is found out, it could be helpful to predict the prognosis of dental implants. MATERIALS AND METHODS A retrospective study of patients rec...

OBJECTIVES This study identified potential general influencing factors for a mathematical prediction of implant stability quotient (ISQ) values in clinical practice. METHODS We collected the ISQ values of 557 implants from 2 different brands (SICace and Osstem) placed by 2 surgeons in 336 patients. Surgeon 1 placed 329 SICace implants, and surgeon 2 placed 113 SICace implants and 115 Osstem i...
