The aim of this study was to determine, firstly,the relation between the failure of a sample of hydroxyapatite-coated implants (HA) and the periodontal parameters of the patient, and secondly, the degree of association between such parameters. The sample was comprised of 52 patients and 158 H.A. coated implants (Integral® by Calcitek), which were revised three years after their insertion. Implant failure was determined according to the criteria of Schnitman and Shulman (1979). A retrospective analytical observational follow-up study was carried out, by means of which the clinical and radiological evolution of the implants was determined. It was found that the peri-implant recession measured facial, lingual, mesial and distal from each implant is the only periodontal parameter associated with the failure of the implant (p=0.008). Bone resorption and periimplant recession were significantly associated (p<0.05),as was probe depth with the gingivitis index in all positions and with the plaque index in the lingual position. A positive correlation was found between the latter two indices (r=0.519; p<0.01). It may be concluded that the appearance of recession around an implant increases the probability of its failure. There was also a positive correlation between the gingivitis index, the plaque index and pocket depth, which is indica tive of the state of the gingival sulcus but not of the success rate of the implant.
