| Abstract | BACKGROUND: Further clarification of the early and late response of peri-implant tissues to surgical insertion and loading of dental implants and the potential associations among the various implant-related measures are likely to improve the evaluation/monitoring of implant sites. Thus, analyses were made of the volume and nitric oxide (NO) profile of peri-implant sulcus fluid (PISF), implant stability, and marginal bone level in relation to different prosthetic designs. METHODS: Seven totally edentulous subjects and 11 partially edentulous subjects were included. Resonance frequency analysis (RFA), marginal bone level measurements, PISF volume, and spectrophotometrically determined nitrite levels were analyzed comparatively at conventionally loaded (CL) implant sites and at implants with removable prostheses (RP; N = 14) and fixed prostheses (FP; N = 11) for a period of 12 months. RESULTS: At implant sites with RP, PISF volume decreased gradually and its lowest level occurred at the end of the experimental period. The PISF nitrite content increased until 6 months and was followed by a significant decrease at 12 months. Compared to baseline, RFA values exhibited a significant decrease at 1 and 3 months. Marginal bone level was significantly lower at all follow-up visits compared to baseline. More volumetric fluctuations of PISF was noted at implant sites with FP. The PISF nitrite content had decreased, compared to baseline, at 6, 9, and 12 months. A general stability was observed for RFA. The marginal bone loss observed at 6 months was followed by a gain at 12 months. An inverse relationship was noted between RFA values and marginal bone levels. CONCLUSION: The prosthetic design particularly seems to affect the NO metabolism around CL implants, whereas it does not seem to have any impact on the stability of dental implants. |

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.
