RESUMO

Researches in literature considered some factors to be related to failure of dental implants treatments. However, some other studies have generated controversy in those results. Some authors also contraindicated dental implants treatment in presence of these factors like systemic diseases, substance abuse, bone grafting before implant installation, postoperative complications and others factors; when some studies demonstrate that these factors, separately, represent only one small parcel of failures in the dental implantology, being not significant. Thus, the objective of this work was to evaluate the factors that can influence in the delayed failure of dental implantations, by means of formularies of patients who had been treated with dental implants in the period of June of 2001 through July of 2006 at the Oral and Maxillofacial Surgery Department of the Piracicaba Dental School - Unicamp. The groups, such as gender, age, main complaint, medical history, reconstructive procedures, dental implant procedures, complications, prosthetic procedures, a minimum follow-up of one year after prosthetic load and implants failure, had been studied in this research. Moreover, each of these factors had been evaluated in the patients who had presented some delayed failure on dental implants treatments, with the purpose to establish any relation of these factors and their influence in the delayed failure of dental implant treatments. 432patients were included on the evaluation of this study with a success rate of 89.3% on dental implants treatment. Primary failure on dental implants presented on 28 patients (6.4%) and 21 patients (4.8%) presented delayed failure. Patients who presented delayed failure did not abuse substances, seven patients had a systemic disease and six treated previously with bone graft. Smoke, systemic disease, reconstructive procedures and complications during surgical treatments had not resulted to be significant on delayed failure indices. Prospective studies are necessary for a best comprehension of these failures in the treatment of dental implants
