(International Journal of Environmental Research and Public Health, 2020)The aim of this study was to evaluate the effects of different implant sites an under-preparation sequence associated with two different implant designs on implant primary stability measured by two ... -
Influence of insertion torques on the surface integrity in different dental implants: an ex vivo descriptive study
(Materials, 2023)Background: The primary objective of this ex vivo study was to assess the influence of increasing insertion torques on three types of dental implants and possible alterations of their microgeometry after ... -
Influence of static navigation technique on the accuracy of autotransplanted teeth in surgically created sockets
(Journal of Clinical Medicine, 2022)The aim of this study was to analyse and compare the position of single-rooted autotransplanted teeth using computer-aided SNT drilling and conventional freehand (FT) drilling, by comparing the planned ... -
Influence of the CAD-CAM systems on the marginal accuracy and mechanical properties of dental restorations
(International Journal of Environmental Research and Public Health, 2020)The aim of this study was to compare the quality of different computer-assisted-design and computer assisted manufacturing systems (CAD-CAM) generated by only one scanner, focusing on vertical fit ... -
Influence of the elastic modulus on the osseointegration of dental implants
(Materials, 2019-03-25)The load transfer from metallic prosthesis to tissue plays an important role in the success of a designed device. From a mechanical behavior point of view, the load transfer will be favored when the ... -
Influence of the titanium implant surface treatment on the surface roughness and chemical composition
(Materials, 2020)The implant surface features affect the osseointegration process. Different surface treatment methods have been applied to improve the surface topography and properties. Trace of different elements may ... -
Interposition of a connective tissue graft or a collagen matrix to enhance wound stability – an experimental study in dogs
(Journal of Clinical Periodontology, 2016)Aim: The aim of this study was to evaluate the role of a connective tissue graft (CTG) or a collagen matrix (CM) interpositioned between flaps and non-shedding hard surfaces on wound stability. Material ... -
Interproximal papilla stability around CAD/CAM and stock abutments in anterior regions: a 2-year prospective multicenter cohort study
(The International Journal of Periodontics & Restorative Dentistry, 2017)The aim of this study was to compare the interproximal papilla stability of restorations supported by computer-aided design/computer-assisted manufacture (CAD/CAM) abutments to those supported by ... -
Intra- and inter-examiner reliability in classifying periodontitis according to the 2018 classification of periodontal diseases
(Journal of Clinical Periodontology, 2022)Aim: To evaluate the inter-examiner reliability in classifying periodontitis using the 2018 classification of periodontal diseases, when used by postgraduate students, academics, and specialist clinicians ... -
Intra-osseous heat generation during implant bed preparation with static navigation: multi-factor in vitro study
