Abstract

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.

Materials and Methods

Twenty Tidal Spiral implants were used for this study. Two implants were placed in each patient in the anterior mandible corresponding to the B and D regions and the implant on the D region was exposed to magnetic field using safer magnet (Neodymium Boron Iron) and the implant on the B region served as a control. Both the implants were compared for stability using Resonance Frequency Analyzer (RFA) at Days 0, 30, 60 and 90. Mean Implant Stability Quotient (ISQ) values were compared on both sides using student’s paired t-test and repeated measures ANOVA (analysis of variance). There was a significant difference in the mean ISQ values, hence, a post-hoc test was done to evaluate whether there is any difference between the follow-ups.

Results

The average ISQ value for implants at 0 day in the B and D regions was 68.6 and 68.7 respectively. The average ISQ value at 30^th day, 60^th day and 90^th day was 73.25, 76.05 and 78.95 respectively on the magnetic side (D region). Whereas on the non-magnetic side (B region) at 30^th day, 60^th day and 90^th day was 68.45, 72.05 and 74.45 respectively.

Conclusion

The implant stability quotient values obtained on the magnetic side were significantly greater than on the non-magnetic side. Positive correlation exists between the magnetic field and osseointegration.
