PURPOSE: The placement of implants allows for re-establishment of function and esthetics following @entity2524 . Immediate implant placement is a relatively recent procedure and has advantages, such as reduced number of surgical procedures, preservation of alveolar bone, reduction of cost and period of edentulism, and increased @entity1 acceptance. However, there are some specific contraindications for the technique, such as the presence of an @entity281 caused by @entity2520 and @entity1548 . The objective of this study was to evaluate the percentage of bone-implant contact of immediate implants placed in periodontally infected sites. MATERIALS AND METHODS: In the first phase, @entity2521 was induced with ligatures in the mandibular premolars of 5 mongrel @entity235 , using the contralateral teeth as controls (received prophylaxis only). After 3 months, in the second phase of the study, 40 implants were placed in the alveoli of both experimental and control teeth. After a healing period of 12 weeks, the animals were euthanized, and the hemimandibles were removed, dissected, fixed, and prepared for histomorphometric analysis of percentage of bone-implant contact. The Mann-Whitney test was used for statistical analysis. RESULTS: The results of the histomorphometric analysis indicated mean bone-implant contact of 62.4% in the control group and 66.0% in the experimental group, a difference that was not statistically significant. DISCUSSION: Histomorphometric results revealed similar bone-implant contact in both groups, with no signs of @entity281 . CONCLUSIONS: It was concluded that periodontally infected sites may not be a contraindication for immediate implantation in this animal model system, if adequate pre- and postoperative care is taken.
