Successful treatment of a large implant periapical lesion that caused paraesthesia and perimandibular abscess

Abstract

Successful treatment of a large implant periapical lesion (IPL) that caused paraesthesia and

perimandibular abscess. IPL is a pathologic phenomenon that rarely involves implants. This event

first described in 1992 with an incidence rate of 0.26–9.9% and the origin is not well known.

The most likely suggested causes are presence of preexisting bone pathology, contamination of

implant surface, bone overheating during implant surgery, vascular ischemia, excessive tightening

of the implant, fenestration of the buccal plate and different implant surface designs. In the present

case report, we describe relatively large periapical lesions involving several implants caused severe

abscess accompanied by transient inferior alveolar nerve paraesthesia and its successful management.

A brief review of the literature and a discussion of possible causes and different treatment plans

are also included.
