Decontamination Using a Desiccant with Air Powder Abrasion Followed by Biphasic Calcium Sulfate Grafting: A New Treatment for Peri-Implantitis

Table 2

Radiographic observations observed at baseline after 2 years and expressed as variations after 2 years. Baseline values were obtained immediately before surgery. Δ = changes of values compared with baseline after 2-year follow-up period. r-BF = the percentage of radiographic bone fill of the defect at 2 years.

Implant site (tooth number)	First bone-to-implant contact (FBIC)
	Mesial (mm)			Distal (mm)			r-BF (%)
	Baseline	2 years	Δ	Baseline	2 years	Δ
12	−3.0 mm	−0.1 mm	+2.9 mm	−8.1 mm	−0.1 mm	+8.0 mm	93.0%
