Immediately restored single post extractive implants: clinical outcomes of a retrospective analysis with 8- 10 years follow-up

Abstract

BACKGROUND: This study evaluated retrospectively the outcomes of immediately restored singlepost-extractive implants over a period of 8–10 years. The clinical records of 62 consecutive patients (meanage 53.2 years; range 40-77 years), rehabilitated with single implants placed in fresh extraction sockets (40maxillary/22 mandibular) were analyzed. All implants were functionalized using an immediate protocol.Outcome measures were implant failure, peri-implant radiographic bone level changes, peri-implantmucosa conditions and gingival aesthetics.RESULTS: The final follow-up interval was 9.1 years (range 8-10.6 years). Three implants (4.8% oftotal) failed, one implant in mandible and two implants in maxilla. No difference in implant failures wasregistered between maxillary and mandibular implants (p=0.967). Mean marginal bone levels at implantplacement and at the last follow up were 0.02±0.04 mm and 1.23±0.43 mm, respectively. Mean marginalbone remodeling averaged 1.21±0.52 mm. Peri-implant mucosa was healthy for the most (98.3%) ofimplants. At 10 years, patients had mesial and distal papilla index scores of 2 or 3 for 84.8% and 81.4% ofimplants, respectively.CONCLUSION: The results of this retrospective long-term study proved excellent survival rate ofimmediately restored single post-extractive implants as well as favorable marginal bone response and softtissue conditions.
