The success of dental implants depends on optimal osseointegration, which is affected by many factors, such as systemic drug administration. In clinical practice, non-steroidal anti-inflammatory drugs(NSAID) are prescribed to deal with chronic inflammation or pain caused by some joint disorders or fractures and to control discomfort after implant surgery. NSAID can inhibit the activity of cyclo-oxygenase, resulting in decreased production of dinoprost, which plays a vital role in bone metabolism. Hence, administration of NSAID may influence bone healing of peri-implants during osseointegration. This article aims to review available data regarding the effects of NSAID on implant osseointegration, as well as on healing or remolding of peri-implant bones.
