A comparative evaluation of bite pressure between single implant prosthesis and natural teeth: An in-vivo study

Aim of the Study: To evaluate and compare bite pressure among individuals with implant prosthesis on one side and natural dentition on the contralateral side in the mandibular first molar region using the Nupai bite scan system. Materials and Methods: A total of 30 individuals (15 in which implant prosthesis on the right side and 15 in which implant prosthesis on the left side) with implant prosthesis on one side and natural dentition on the contralateral side participated in the study. The bite pressure was measured at the first molar area on both sides using Nupai bite scan. Results: Maximum bite pressure, average bite pressure, and the amount of the pressed area were found to be more on the natural dentition side in comparison to the side with implant prosthesis. The average pressure on natural teeth was 25.33 MPa and on implant prosthesis, 21.27 MPa. Conclusion: The present study concludes that the measured bite pressure at the natural dentition side is found to be higher than those at the fabricated implant prosthesis side. P value for average bite pressure is 0.033, which is significant (P < 0.05).
