The effect of the distance from the implant-abutment interface to the porcelain-abutment bonded interface on marginal bone loss: a 4-5 year retrospective study

Abstract

Abstract: Objective: To analyze the effect of the distance from Bicon implant-abutment interface (IAI) to prosthesis-abutment bonded interface(PAI) on marginal bone loss(MBL). Methods: Select the patients who meet the criteria from June 2011 to December 2014, and analyze the correlation between the distance between IAI and PAI and MBL by imaging. Results: On the two-dimensional level, the vertical distance and distance between points from IAI to PAI showed a significant correlation with MBL(P<0.01), and the degree of correlation was weak. There was no significant correlation between horizontal distance and MBL (P>0.05). Conclusion: Without affecting aesthetics, properly increasing the distance between IAI and PAI is beneficial to the preservation of bone tissue.

Key words: Bicon implant, bond, marginal bone loss
