General characteristics of the included studies.

Authors	Year	Study type	Number of subjects/; implants	Type of defect	Treatment	Considered parameters	Results
Behneke et al. [27]	2000	Pros.	17/25	NR	Surgical debridement and air-polishing with bicarbonate + GBR with autogenous bone	Marginal bone loss (MBL); horizontal bone loss (HBL); vertical bone loss (VBL)	Two failures; median MBL: from 6.3 mm to 2.1 mm (3 y); median HBL: from 1.8 mm to 2.1 mm (3 y); median VBL: from 4.5 mm to 0.0 mm
de Mendonça et al. [28]	2009	Case series	10/10	NR	Surgical debridement + abrasive sodium carbonate air-powder + resin curettes	BI; PI; PD; CAL; TNF-a	Mean PD reduction: 2.4 mm (1 y); mean CAL reduction: 2.0 mm (1 y). The total amount of TNF-a significantly reduced over time
Máximo et al. [30]	2009	Pros.	13/13	NR	Access flap + Teflon curettes + air-powder (sodium carbonate)	PD; CAL	25% with PD ≥ 5 mm after 3 months. Levels of Treponema denticola, Tannerella forsythia, and Parvimonas micra and of Fusobacterium nucleatum were lower after treatment
Duarte et al. [29]	2009	Pros.	20/20	NR	Access flap + resin curettes + air-powder (sodium carbonate)	PD	Mean PD: from 7.5 mm to 4.4 mm (3 mo). Significant difference in inflammatory cytokines between healthy and affected implants
Toma et al. [31]	2014	Retro.	22/22		Air-abrasive device versus plastic curettes + cotton pellets + saline; no GBR	PD	Significant reduction of clinical parameters in all groups; better improvements for air-abrasive device regarding gingival index and probing depth; no peri-implantitis resolution

NR: not reported; PD: probing depth; CAL: clinical attachment level.
