ABSTRACT
		                        			Implant periapical lesion (IPL) is also known as retrograde peri-implantitis and as the name suggests, 
it involves inflammation surrounding the apical part of the dental implants. Previously, many studies 
have reported the event of IPL that further delays osseointegration, and some reported failure of 
implant placement due to this disease. In this article, we described two cases of early dental implant 
failure that was associated with active IPL and correlated the clinical and radiographical findings with the 
histopathological findings.
