OBJECTIVE To determine the unique contribution of geometrical design characteristics of orthodontic mini-implants on maximum insertion torque while controlling for the influence of cortical bone thickness. METHODS Total number of 100 cylindrical orthodontic mini-implants was used. Geometrical design characteristics of ten specimens of ten types of cylindrical self-drilling orthodontic mini-im...

This study aimed to investigate the influence of implant design (in terms of diameter, length, and thread shape), in-bone positioning depth, and bone posthealing crestal morphology on load transfer mechanisms of osseointegrated dental implants based on platform-switching concept. In order to perform an effective multiparametric comparative analysis, 11 implants different in dimensions and in th...

T he use of dental implants to replace the natural tooth system has become commonplace in the contemporary restorative and surgical dental practice.1,2 Substantiation of their efficacy has been well-documented in restorative, cosmetic, and surgical dental literature,1,2 and with the advancements in surgical techniques and implant design features, their use in the esthetic zone has become a succ...

We study the 3-Coloring problem in graphs with small diameter. In 2013, Mertzios and Spirakis showed that for $n$-vertex diameter-2 this can be solved subexponential time $2^{\mathcal{O}(\sqrt{n \log n})}$. Whether polynomial remains a well-known open question area of algorithmic graph theory. paper we present an algorithm solves $2^{\mathcal{O}(n^{1/3} \log^{2} n)}$. This is first improvement ...
