Treatment of peri-implantitis with granulation tissue removal and mechanical cleansing

using R Brush & I Brush


Pre-operative Situation

- A severe buccal dehiscence of the surrounding bone with granulation tissue

- Marginal bone loss of over 2/3

- Maintained vertical height of bone wall (except for the buccal aspect)

- HDD (horizontal defect dimension) of less than 2mm

- PD 10mm, BOP +, Pus discharge −, Implant mobility −

 

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.


Bio-Oss (granule size of 1 to 2mm) was applied around the cleansed implant and in the bone defect.

Cement retained 2-unit prosthesis.

To assure effective hygiene procedure of the implant, the superstructure connection, which was the cause of this periimplantitis, was modified.

4-month outcome: PD 3mm, BOP −, Pus –
