ABSTRACT
Purpose@#This study investigated the complications and patterns of implants that confronted with the extruded natural teeth. @*Materials and Methods@#Among patients who received implant treatment between 2006 and 2018 at Chosun University Dental Hos-pital, only implants that had a maintenance period of at least 5 years and that both implants and confronting natural teeth could bemeasured and compared on a radiograph were selected. They were divided into two groups. Group 1, experimental group consisted of Implants confronting the extruded natural posterior teeth (n = 167: maxilla (Group 1max ) = 92, mandible (Group 1man ) = 75) and Group 2, control group consisted of Implants confronting the normal natural posterior teeth (n = 656: maxilla (Group 2max ) = 272, mandible (Group 2man ) = 384). @*Results@#The incidence of complications between Group 1 and Group 2 was statistically significant. In particular, there was a statistically significant difference between the frequency of marginal bone loss and the amount of marginalbone loss. @*Conclusion@#The extruded natural tooth may cause more frequent complications including bone resorption in the oppos-ing implant.
