Background: In orthodontic treatment, mini-screws can provide maximum anchorage conditions. If the miniscrew stability is compromised, this could jeopardize outcomes of treatment or biomechanics. Photobiomodulation therapy (PBMt) beneficial for biological tissues since it promotes wound healing with its anti-inflammatory and osteo-stimulatory properties. Objectives: The purpose study was to eva...
the focus of this paper is to evaluate the influence of mechanical characteristics of the implant on primary stability in different bone types, based on resonance frequency analysis (rfa).a number of 60 nobel biocare replace select tiunit tapered implants of two different lengths (10 mm and 13 mm) and three different widths as 3.4 mm (narrow platform (np)), 4.3 mm (regular platform (rp)) and 5 ...
BACKGROUND The purpose of this study was to compare a parallel wall design implant to a tapered apex design implant when placed in the posterior maxilla using two different surgical protocols. METHODS Twenty-seven patients (30 implants) were divided into three groups. All implants were 4 mm wide in diameter and 8 mm long. Group A received 10 tapered implants (OSPTX) (Astra Tech OsseoSpeed TX™...
A novel technique for measurement of orthodontic mini-implant stability using the Osstell ISQ device
Reaction of 2,3,6,7,10,11-hexaaminotriphenylene with Ni in aqueous NH3 solution under aerobic conditions produces Ni3(HITP)2 (HITP = 2,3,6,7,10,11-hexaiminotriphenylene), a new two-dimensional metal−organic framework (MOF). The new material can be isolated as a highly conductive black powder or dark blue-violet films. Two-probe and van der Pauw electrical measurements reveal bulk (pellet) and s...
