| Abstract | PURPOSE: To study the probability of using Image Guided Implantology (IGI) for planning and execution of a dental plan of 3 implants in a geometric pattern that fits a prefabricated metal frame accurately, simulating provisional restoration in immediate loading. MATERIAL AND METHODS: Ten mandible models were imaged by standard computed tomography. Three implants, two in the premolar and one in the molar area on each side of the jaws, were planned by use of the IGI system (Image Navigation Ltd, Moshav Ora, Israel). Two millimeter drilling and subsequent 3 millimeter widening drilling was performed with the real-time computerized navigation technology in the 120 sampling sites. In each step, parallel pins were inserted, and metal gauging frames with preplanned holes of incremental diameters and in the predefined geometric pattern were placed on the pins to evaluate the precision of fit. RESULTS: Full success was obtained in fitting all three 3-mm pins, with frames having clearance of 0.5 or 1 mm, and in matching pairs of pins 2 or 3 mm in diameter at clearances of 0.5 mm or greater. With more constrained clearances, matching of all 3 pins was 80% and 95% successful with 2-mm pins (clearance of 0.25 and 0.5 mm, respectively) and 60% and 95% successful with 3-mm pins (clearance of 0 and 0.25 mm, respectively). Some laterality bias was observed. CONCLUSIONS: This preliminary study shows that the IGI system enables accurate planning of implant number and location to be achieved together with planning for a prefabricated metal frame for immediate loading. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
