Superficie del implante como indicador de riesgo en enfermedades periimplantares

Abstract

SUMMARY The inflammatory lesions that develop in the tissues around implants are collectively recognized as peri-implant diseases. The view that microorganisms play a major role in the development of peri- implant diseases is supported by several clinical findings. Indicator factors for peri-implant diseases including periodontitis, diabetes, genetic traits, poor oral hygiene, smoking, alcohol consumption, absence of keratinized mucosa and implant surface. Several studies have demonstrated that implant surface characteristics can influence the rate and degree of bone to implant contact, especially implants with surface roughness that resulted in greater bone integration compared with smooth surface implants. On the other hand, some authors have demonstrated that implant abutments with rough surfaces tended to accumulate more plaque than those with a smooth surface. Under this circumstance, different implant surfaces may influence the peri-implant microbiota and possibly the inflammatory process around implants. However, the effects of various implant designs and surface coatings on peri-implant inflammation have caused controversy. KEY
