Clinical factors affecting the translucency of monolithic Y-TZP ceramics
Pekkan, Gürel; Özcan, Mutlu; Subaşı, Meryem Gülce (Springer, 2020)The use of monolithic yttria-stabilized tetragonal zirconia polycrystal (Y-TZP) ceramics in aesthetically critical regions is questionable because of the insufficient translucency and opacity of the restorations. Intrinsic ... -
Effect of different sintering conditions on microstructural characterisation of Co-Cr metal laser powder
Pekkan, Gürel; Taşçı, Eda; Pekkan, Keriman; Ispalarlı, Murat (Inderscience Publishers, 2020)Co-Cr alloys have been used for many years in dentistry. In recent years, the fabrication of prosthetic restorations from Co-Cr alloys by metal laser sintering method has become widespread. This method is a combination of ... -
Effect of micro blasting process parameters on 3D surface topography and surface properties of zirconia (Y-TZP) ceramics
Yetik, Okan; Yavuzyeğit, Berzah; Yıldıran Avcu, Yasemin; Koçoğlu, Hurol; Pekkan, Gürel; Sarıdağ, Serkan; Avcu, Egemen (Wiley, 2021)The present study aims to examine the effects of operational parameters on the surface topography and wear mechanisms of monolithic and conventional yttria-stabilized zirconia (Y-TZP) ceramics in the micro blasting process, ... -
Evaluation of corrosion resistance of Co-Cr alloys fabricated with different metal laser sintering systems
Tuna, Süleyman Hakan; Karaca, Erhan; Aslan, İsmail; Pekkan, Gürel; Özçiçek Pekmez, Nuran (Korean Academy of Prosthodontic, 2020)PURPOSE. The aim of this study was to evaluate the corrosion resistance of the specimens produced by five different commercial metal laser sintering (MLS) systems with their recommended Co-Cr alloy powders. MATERIALS AND ... -
Evaluation of median mandibular flexure values in dentulous and edentulous subjects by using an intraoral digital scanner
Gülsoy, Merve; Tuna, Süleyman Hakan; Pekkan, Gürel (Korean Acad Prosthodontics, 2022)PURPOSE. Mandibular flexure is a crucial phenomenon that may affect the success of rigid bilateral mandibular prosthetic treatment. The aim of this study was to determine the amount of median mandibular flexure (MMF) that ... -
Factors affecting the translucency of monolithic zirconia ceramics: A review from materials science perspective
Pekkan, Gürel; Pekkan, Keriman; Çukurluöz Bayındır, Banu; Özcan, Mutlu; Karasu, Bekir (Japanese Society for Dental Materials and Devices, 2020)The use of monolithic [yttria (Y2O3)-stabilized tetragonal zirconia (ZrO2) polycrystalline] (Y-TZP) ceramics to restore teeth is expanding in dentistry. However, there are still some problems about color matching and the ...
