The objective of this study was to predict time-dependent bone remodeling around tissue- and bone-level dental implants used in patients with reduced bone width. The remodeling of bone around titanium tissue-level, and titanium and titanium-zirconium alloy bone-level implants was studied under 100 N oblique load for one month by implementing the Stanford theory into three-dimensional finite element models. Maximum principal stress, minimum principal stress, and strain energy density in pen-implant bone and displacement in x- and y- axes of the implant were evaluated. Maximum and minimum principal stresses around tissue-level implant were higher than bone-level implants and both bone-level implants experienced comparable stresses. Total strain energy density in bone around titanium implants slightly decreased during the first two weeks of loading followed by a recovery, and the titanium-zirconium implant showed minor changes in the axial plane. Total strain energy density changes in the loading and contralateral sides were higher in tissue-level implant than other implants in the cortical bone at the horizontal plane. The displacement values of the implants were almost constant over time. Tissue-level implants were associated with higher stresses than bone-level implants. The time-dependent biomechanical outcome of titanium-zirconium alloy bone-level implant was comparable to the titanium implant.

Predicting time-dependent remodeling of bone around immediately loaded dental implants with different designs Eser, Atilim; Tönük, Ergin; Akça, Kıvanç; Cehreli, Murat Cavit (Elsevier BV, 2010-01-01) The purpose of this study was to predict time-dependent biomechanics of bone around cylindrical screw dental implants with different macrogeometric designs under simulated immediate loading condition. The remodeling of bone around a parallel-sided and a tapered dental implant of same length was studied under 100 N oblique load by implementing the Stanford theory into three-dimensional finite element models. The results of the analyses were examined in five time intervals consisting loading immediately after...
Etiology of senile osteoporosis - A hypothesis Atik, O. Sahap; Uslu, M. Murad; Eksioglu, Fatih; Satana, Tolgay (Ovid Technologies (Wolters Kluwer Health), 2006-02-01) Osteoporosis is a major health problem characterized by compromised bone strength predisposing patients to an increased risk of fracture. It may cause morbidity and mortality in elderly men and women. The etiologic factors that lead to senile osteoporosis still are unclear.
Functional evaluation of intraarticular severely comminuted fractures of the calcaneus with gait analysis BOZKURT, Murat; Kentel, B. Behzat; Yavuzer, Gunes; Öçgüder, Ali; Heycan, Cengiz; Tönük, Ergin (Elsevier BV, 2004-11-01) Twenty-one patients (23 feet) treated nonsurgically for severely comminuted intraarticular fractures of the calcaneus were evaluated prospectively with a clinical scoring scale and computerized gait analysis. All patients had Sanders type III and type IV fractures. The treatment protocol consisted of no closed reduction, immobilization in removable splint, physiotherapy after edema subsided, and weightbearing after 8 weeks. All patients had a minimum follow-up of 2 years (mean, 38 months). Clinical results ...
Resorbable PCEC/gelatin-bismuth doped bioglass-graphene oxide bilayer membranes for guided bone regeneration Pazarçeviren, Ahmet Engin; Evis, Zafer; Keskin, Dilek; Tezcaner, Ayşen (IOP Publishing, 2019-05-01) Guided bone regeneration (GBR) is a therapeutic modality applied prior to dental implant placement to increase bone density at the defect site or during placement for directing bone growth around implant. In this study, an asymmetric, bilayer structure was prepared by covalently bonding a dense polycaprolactone-polyethylene glycol-polycaprolactone (PCEC) membrane layer with a hydrogel layer composed of bismuth doped bioactive glass (BG, 45S5) and graphene oxide (GO) particles incorporated in gelatin. Struct...
Numerical simulation of the effect of time-to-loading on peri-implant bone AKÇA, KIVANÇ; Eer, Atilim; Canay, Senay (Elsevier BV, 2010-01-01) Purpose: To evaluate the effect of time-to-loading on trabecular bone around single-tooth dental implants using numerical solutions based on computer models.
