PURPOSE The aim of this study was to evaluate the influence of the length and diameter of the implant incorporated under the saddle of a distal-extension removable partial denture, acting as support. MATERIALS AND METHODS Six hemi-mandibular models were made with the presence of left inferior cuspid and first bicuspid, with the following differences:(More)
PURPOSE : This study evaluated the influence of distal extension removable partial denture associated with implant in cases of different bone level of abutment tooth, using 2D finite element analysis. MATERIALS AND METHODS : Eight hemiarch models were simulated: model A-presenting tooth 33 and distal extension removable partial denture replacing others(More)
OBJECTIVES The non-homogenous aspect of periodontal ligament (PDL) has been examined using finite element analysis (FEA) to better simulate PDL behavior. The aim of this study was to assess, by 2-D FEA, the influence of non-homogenous PDL on the stress distribution when the free-end saddle removable partial denture (RPD) is partially supported by an(More)
PURPOSE The aim of this research was to assess, by means of, the bi-dimensional finite element method, the best implant location in the alveolar edge, through stress distribution and support structure displacement of a distal extension removable partial denture associated with an osseointegrated implant of 10.0 x .75 mm, acting as abutment for the denture(More)
The alveolar ridge shape plays an important role in predicting the demand on the support tooth and alveolar bone in the removable partial denture (RPD) treatment. However, these data are unclear when the RPD is associated with implants. This study evaluated the influence of the alveolar ridge shape on the stress distribution of a free-end saddle RPD(More)
Cultural heritage is experienced differently by different visitors. The more erudite know beforehand what they intend to explore when visiting a monument, a museum or a city. On the other side, least erudite visitors usually know and are capable of expressing some of their preferences but do not realize exactly what to see and explore. Physical and(More)
