R Brush was used for the granulation tissue removal and mechanical cleansing at 8,000rpm with copious irrigation.

i-Brush was used for the granulation tissue removal and mechanical cleansing in the narrow and deep noncircumferential defect area. After the decontamination by chlorhexidine gluconate solution, SLA surface was treated with phosphate etching for 10 seconds, and washed by saline.

In order to promote remineralization on the implant surface, β−TCP powder was applied by air abrasion over the implant surface.
