The loss of one or more teeth is normally treated with conventional fixed or removable partial dentures or with implant supported fixed or removable dentures. This study investigated stresses formed around the implant and the antagonist natural tooth under occlusal force in the substitution of a missing lower first molar with a rigid or resilient IMZ (Intra Mobil Zylinder) implant, using the finite element stress analysis method. The results indicate that a bite force of 143 N resulted in high compressive stresses around the roots of a natural tooth opposing a restoration supported by an IMZ implant with rigid type abutment. It is speculated that these high compressive stresses may contribute to intrusion of the tooth.

Passive haptic robotic arm design
Yılmaz, Serter; Konukseven, Erhan İlhan; Gürocak, Hakan; Department of Mechanical Engineering (2010)
The implant surgery replaces missing tooth to regain functionality and look of the normal tooth after dental operation. Improper placement of implant increases recuperation periods and reduces functionality. The aim of this thesis is to design a passive haptic robotic arm to guide dentist during the implant surgery. In this thesis, the optimum design of the 6R passive haptic robotic arm is achieved. The methodology used in optimization problem involves minimization of end-effector side parasitic forces/torq...
Effects of the type and rigidity of the retainer and the number of abutting teeth on stress distribution of telescopic-retained removable partial dentures
Sahin, Volkan; Akaltan, Funda; Parnas, Levend (Elsevier BV, 2012-3)
Background/purpose:Little is known about the force-transmission characteristicsand patterns of telescopic-retained removable partial dentures (RPDs) as related to their typeand rigidity (rigid and/or resilient) and the number of abutting teeth supporting the tele-scopic dentures. In this study, we compared the strain around the abutting teeth and eden-tulous ridges supporting telescopic-retained RPDs with different designs using a straingauge technique.Materials and methods:A maxillary model including four ...
Design and mechanical analysis of a new dental implant that would mimic natural tooth with a periodontal ligament
Pektaş, Ömer; Tönük, Ergin; Department of Mechanical Engineering (2012)
Dental implant is an artificial dental root that is used to construct dental restorations, similar to the original teeth, in order to regain the function of missing teeth of patients experiencing tooth loss. At the interface between the jawbone and the roots of natural teeth, a thin, elastic, shock absorbing tissue, called the periodontal ligament (PDL), forms a cushion which provides certain mobility to the natural teeth. The restorations supported by dental implants, however, involve completely rigid stru...
Effects of hydrogen peroxide bleaching on human dentin and enamel microstructure and function
Gökduman, Kurtuluş; Severcan, Feride; Department of Biotechnology (2005)
In recent years bleaching of vital teeth has become popular among both dentist and patients. Different bleaching agents were used for this purpose. They are either applied professionally at high dose (office bleaching) or by patient at lower dose (home bleaching). In the present work we studied the effects of a high concentration bleaching agent (35% hydrogen peroxide), and a low concentration bleaching agent (17% carbamide peroxide) on human enamel and dentin using Fourier Transform Infrared (FTIR) Spectro...
Predicting bone remodeling around tissue- and bone-level dental implants used in reduced bone width
Eser, Atilim; Tönük, Ergin; Akça, Kıvanç; Dard, Michel M.; Cehreli, Murat Cavit (Elsevier BV, 2013-09-03)
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 ...
