RESUMO
BACKGROUND: Few studies have reported the outcomes of immediate placement at infected post-extraction sites. The aim of this study was to compare clinical and radiological outcomes of immediately placed implants with immediate prosthetic provisionalization in sockets with or without acute periapical pathology. MATERIAL AND METHODS: A total of 100 patients with immediately placed implants with immediate provisionalization and 1- year of follow up were included (50 patients with acute periapical pathology and a control group of 50 patients without acute periapical pathology). Clinical parameters (bleeding on probing, buccal keratinized mucosa width, clinical recession, and probing depth) and radiological parameters (distance from implant shoulder to first point of bone-to-implant contact [IS-BIC]) were assessed. RESULTS: Clinical parameters showed no significant differences between the study and control groups after 1-year follow up (p>0.05). IS-BIC presented the following values: 0.35 ± 0.51 mm (study group) and 0.15 ± 0.87 mm (control), without significant differences between the groups (p=0.160). None of the 50 radiographs of immediate implants placed in sockets with periapical pathology revealed retrograde peri-implantitis. CONCLUSIONS: Immediate placement of implants with immediate prosthetic provisionalization at sites with acute periapical pathology can be a successful treatment modality for at least 1-year.
