Abstract

Some studies comparing immediate functionally loaded and non-functionally loaded implants have found a significant difference in crestal bone loss and implant survival rates while some others have found immediate functionally loaded and non-functionally loaded implants to be comparable with respect to the same parameters. The previous studies only illustrate the lack of consensus regarding the loading protocol for immediately loaded implants. There exists a dilemma regarding the protocol for immediate loading; this prospective experimental study was conducted to determine whether there exists a difference in bone response with respect to immediate functional and non-functional loading. The study sample consisted of 120 subjects who were partially edentulous in the mandibular arch and were randomly divided into 2 groups, each consisting of 60 subjects. Group I subjects were restored with implant system with immediate functional loading and Group II with implants system with immediate non-functional loading. Both groups were evaluated at baseline, 3 months and 6 months for crestal bone level changes and radiographic bone density changes. It was concluded from the study that immediate loading of implants helped to stimulate bone ossification around implants at the lateral apical level at 3 and 6 months and at the crest from 3 months to 6 months. Furthermore, the immediate functional loading of implants resulted in a significantly greater degree of bone demineralization at the alveolar crest from the time of implant placement up to 3 months compared with immediate nonfunctional loading.
