The Brånemark dental implant has undergone progressive development in terms of both the implant body itself and the components connecting the implant to the prosthesis. Many screw and abutment designs have been developed, with various degrees of success. About 15 years ago, CAD (computer-assisted design)-CAM (computer-assisted manufacture) technology was introduced to dentists. More recently CA...

Computer assisted surgery (CAS) was used to improve the positioning of implants during total knee arthroplasty (TKA). Most studies have reported that computer assisted navigation reduced the outliers of alignment and component malpositioning. However, additional sophisticated studies are necessary to determine if the improvement of alignment will improve long-term clinical results and increase ...

The purpose of this study was to assess the effectiveness of CALL in developing reading proficiency of Iranian EFL learners in comparison to paper-based instruction and to investigate any significant difference in the reading comprehension of the high and low proficient learners after receiving computer-assisted instruction (CAI). This study also investigated the participants’ attitudes toward ...

Computer-assisted navigation is used to improve the accuracy and precision of correction angles during high tibial osteotomy. Most studies have reported that this technique reduces the outliers of coronal alignment and unintended changes in the tibial posterior slope angle. However, more sophisticated studies are necessary to determine whether the technique will improve the clinical results and...

Before embarking on a full-scale study, it was important to gain some understanding of the user’s perspective. In a preliminary study conducted in 1999 teachers used commercially available speech technology in a singing lesson, incorporating the computer-assisted visual feedback in whatever way they found useful. Interview data from teachers and students indicated that it is certainly both feas...

Fabricating a surveyed prosthesis beneath an existing partial removable dental prosthesis (PRDP) is a challenging and time-consuming procedure. The computer-aided design/computer-assisted manufacturing (CAD/CAM) technology was applied to fabricate a retrofitted, surveyed zirconia prosthesis to an existing PRDP. CAD/CAM technology enabled precise and easy replication of the contour of the planne...

This study investigated teachers’ views toward computer technology in teaching English pronunciation. In order to select teachers for the semi-structured interview, the researcher used a questionnaire and distributed it to 25 teachers from two Islamic Azad Universities of Guilan, Iran. The researcher chose 15 of them based on their answers to the questionnaire. Then a qualitative method d...

Internal control systems and auditing obligations have changed and transformed dramatically due to recent trends. Computer-assisted audit techniques and ERP computer auditing systems are being designed to address growing demands in auditing. These assist auditors in performing their auditing work where information technology is in place. However, they possess some technical limitations that are...

the interaction of radiation with cells and tissues has a random nature. therefore, understanding the random nature of cell killing that is determined by poisson distribution statistics is an essential point in education of radiation biology. radbiostat is a newly developed educational matlab-based software designed for computer-assisted learning of the target theory in radiation biology. altho...

INTRODUCTION Computer assisted surgery was pioneered in early 1990s. The first computer assisted surgery (CAS) total knee replacement with an imageless system was carried out in 1997. In the past 25 years, CAS has progressed from experimental in vitro studies to established in vivo surgical procedures. METHODS A comprehensive body of evidence establishing the advantages of computer assisted s...
