Iatrogenic mandible fracture is a rare complication of tooth extraction with an incidence between 0.0033–0.0034%. This study retrospectively analyzes total 8 patients who underwent lower molar associated during removal in the period from April 2006 to March 2019. The assessed parameters were age and sex patients, method extraction, side distribution fracture, type extracted tooth, position thir...

objective : the aim of this study was to evaluate fracture characteristics of rigid two-tooth segments splinted with fiber reinforced composite (frc), with and without application of simulated masticatory forces. material and methods: in this experimental study, 80 extracted maxillary bicuspids were joined in pairs from the buccal aspect using frc. the specimens were divided into two groups. in...

Received: 6 Sept 2012 Accepted: 21 May 2013 Abstract Background and Aim: Tooth fracture is a common complication following MOD restorations.This study sought to assess the effect of different cusp coverage patterns on fracture resistance of maxillary premolar teeth in MOD composite restorations. Materials and Methods: In this invitro experimental study, 40human maxillary sound premolar teeth we...

OBJECTIVE Tooth fracture is a common dental problem. By extension of cavity dimensions, the remaining tooth structure weakens and occlusal forces may cause tooth fracture. The aim of this study was to evaluate and compare the fracture resistance of teeth restored with direct and indirect composite restorations. MATERIALS AND METHODS Sixty-five sound maxillary premolar teeth were chosen and ra...

Background: The use of implants to treat edentulous jaws has become a well-established and accepted contemporary clinical method. Interest in the use of implants for fully or partially edentulous patients has increased. Aim: To evaluate the prosthetic complications experienced by implant supported over-denture patients. Materials and method: The present study was conducted in the department of ...

This study evaluated the effects of 10% alphatocopherol on the fracture resistance of endodontically treated teeth subjected to tooth bleaching with hydrogen peroxide and immediately restored with composite resin. Fifty bovine incisors were selected, including 10 sound teeth that constituted the control group (G1 (C)). The remaining 40 teeth, which were endodontically treated, were divided into...

PURPOSE To evaluate the cumulative survival rate (CSR) and mechanical complications of single-tooth Ankylos® implants. MATERIALS AND METHODS This was a retrospective clinical study that analyzed 450 single Ankylos® implants installed in 275 patients between December 2005 and December 2012. The main outcomes were survival results CSR and implant failure) and mechanical complications (screw loo...

abstract : the crown-root fracture is a common tooth injury which compromises the biological width and need proper endodontic and prosthodontic treatment to achieve acceptable clinical outcome. this case report describes clinical management of crown-root fracture in maxillary central incisors which was successfully treated by forceps eruption with 180˚ rotation to restore the biological width. ...
