INTRODUCTION: After implant placement, a stress-free healing period of 3-6 months is a pre-requisite to achieve good osseointegration. If this duration could be reduced, the patients would feel happier. Eventhough, immediate loading of implants is a clinically feasible concept; it is not possible in certain situations. Few studies have shown that Static magnetic field is useful to promote bone formation faster after the bone is wounded. AIM: This pilot study was intended to evaluate the tissue response after implant placement under the influence of magnetic field...
