Outline of Final Research Achievements	Recently, various types of implants with different surface properties have been rapidly developed with the aim of achieving early osseointegration. The objective of this study was to investigate how the connection of superstructures to implants with different surface properties affects the surrounding bone. and we show the results suggest the when implants with different surface properties are connected, machined implants at the most distal sites can be a potential risk factor for implant-bone binding. Increased C/I ratio may not be a risk factor for implant failure under peri-implant muccosa is kept healthy.
