OBJECTIVES To evaluate whether changes in marginal bone level (MBL) around implants, in sites with different bone types, affect the over time implant stability measured by resonance frequency analysis (RFA). MATERIAL AND METHODS Seventy-eight implants were inserted into jawbones of 32 patients using a two-stage surgical protocol, and implant bone sites(More)
OBJECTIVE To investigate in vivo the correlation between the bone microarchitecture of implant bone sites, bone tissue classification subjectively assessed in radiographs and primary implant stability. MATERIAL AND METHODS Periapical and panoramic radiographs were obtained from 32 partially edentulous patients. Three surgeons classified bone quality at(More)
OBJECTIVE The aim of this study was to investigate the influence of different bone tissue characteristics of implant sites on changes in marginal bone level and implant stability over time. MATERIAL AND METHODS One hundred and one implants were inserted in 41 patients. Cortical bone thickness of the alveolar ridge was measured on computed tomography (CT)(More)
BACKGROUND Histomorphometry and microcomputed tomography (microCT) have been used in implant studies but need better understanding before being used as equivalent methods. PURPOSE The purpose of this study was to investigate the agreement between 2D (histomorphometry) and 3D (microCT) reference methods for assessing jawbone microarchitecture in vivo. (More)
BACKGROUND AND OBJECTIVES Computer vision extracts features or attributes from images improving diagnosis accuracy and aiding in clinical decisions. This study aims to investigate the feasibility of using texture analysis of periapical radiograph images as a tool for dental implant treatment planning. METHODS Periapical radiograph images of 127 jawbone(More)
The single-implant mandibular overdenture (SIMO) has been proposed as an alternative for edentulous patients who are poorly adapted to their dentures due to low retention and stability of the conventional mandibular complete denture (CD). However, there is a lack of evidence regarding the effectiveness of SIMO, which can be measured by examining patient(More)
