Introduction: The abutment screw loosening has been a common clinical mishap affecting the success of the implant in the long run. With repeated insertion and removal of the implant abutment screw during fabrication of the restoration, frictional wear at the microscopic level in the screw threads had been reported. Aim: To assess the effectiveness of screw coating in minimizing abutment screw loosening in dental implants in literature. Results: A database search yielded a total of 14 articles out of which 8 were excluded based on the title and abstracts not relevant to the topic of our interest and 6 were included based on the core data. The six articles were reviewed, and four articles were consolidated to perform the meta-analysis. All the four studies showed a similar expression of outcome measure; the detorque values were expressed in Ncm. The χ2 = 144.71, df = 3, p < 0.00001, and I2 = 98%. Hence, a Random Effect model with 95% confidence interval was chosen for meta-analysis. The overall effect observed in the metaanalysis was Z = 0.36, p = 0.72, and no statistically significant differences were observed between the coated and noncoated screws with respect to detorque values. Conclusion: This meta-analysis inferred that there is no difference between the coated and noncoated screws with respect to screw loosening. Clinical significance: Noncoated screws are equally effective as coated screws with respect to abutment loosening in endosseous implants. Hence, the additional cost and technique sensitivity incurred with powdered screws may not drastically improve the rate of failure due to screw loosening.
