BACKGROUND Membrane elevation in combination with implant placement without biomaterials is a rather new technique proposed for sinus lifting. PURPOSE This study assessed the clinical outcome of such technique during the first year of loading. MATERIAL AND METHODS Fifteen patients with a mean residual bone height of 6.2 mm were consecutively recruited(More)
AIM To analyse the shaping ability of two new NiTi rotary systems in molar curved canals. METHODOLOGY Thirty molar root canals with curvatures from 24 degrees to 69 degrees were divided into two groups that were balanced in terms of curvature. The canals in one group were shaped using the Mtwo (Sweden & Martina, Padova, Italy) and the canals in the other(More)
OBJECTIVES This study aimed at assessing the clinical outcome of narrow diameter implants in the treatment of knife-edge edentulous maxillas of adequate bone height but inadequate width (class IV of Cawood and Howell). MATERIAL AND METHODS Twelve consecutive patients (eight women and four men, mean age 58 years) with class IV atrophic edentulous maxillas(More)
BACKGROUND Resonance frequency (RF) analysis is frequently used to monitor implant stability in patients. The influence of transducer orientation on RF of implants placed in jawbone has not been evaluated. PURPOSE The aim of this study was to evaluate to what extent transducer orientation influences RF. The second aim was to evaluate if measurements taken(More)
OBJECTIVES The aim of the present study was to evaluate differences in the ultimate fracture resistance of titanium and zirconia abutments. MATERIAL AND METHODS Twenty titanium fixtures were embedded in 20 resin mandible section simulators to mimic osseointegrated implants in the premolar area. The embedded implants were then randomly divided into two(More)
BACKGROUND Implant treatment in the partially edentulous maxilla is often challenging because of minimum bone volumes in distal direction. PURPOSE The aim of this study was to evaluate, after 1 year of loading, the outcome of three-unit fixed partial dentures supported by two implants in the retrocanine triangle. MATERIALS AND METHODS Twenty patients(More)
INTRODUCTION The study evaluated a null-hypothesis of no differences of fit between stock abutments and CAD/CAM titanium, gold sputtered and zirconia abutments when examined for radiographic adaptation and Scanning Electron Microcopy (SEM) at their inner aspect. The agreement between microscopic and radiographic fit was also assessed. METHODS Implants(More)
This study analyzed the abilities of ProTaper and GT Rotary files to shape the curved canals of extracted mandibular molars. Twenty mesial canals with curvatures ranging from 23 to 54 degrees (Weine analysis) were radiographically selected from a group of 58 molars. The specimens, divided into two groups, were instrumented using the two systems according to(More)
OBJECTIVES To evaluate, on the base of cone beam computed tomography (CBCT) fractal dimension, bone quality changes surrounding the apical portion of immediate implants placed under higher insertion torque utilizing an undersized drilling technique. MATERIALS AND METHODS Three patients were enrolled in this study. Single implants were placed into fresh(More)
PURPOSE Insertion torque and resonance frequency analysis are currently used to assess the initial biomechanical competence of an implant. It would be advantageous to have this information during treatment planning. Therefore, the aim of this study was to assess the correlation between a descriptor of bone architecture, namely the fractal analysis of plain(More)
