Immediate placement of tapered implants with a moderately rough anodized surface and smooth collar in fresh extraction sockets: A retrospective analysis with 10-year follow-up.

Abstract

There is limited long-term data on hard- and soft-tissue outcomes of implants immediately placed in postextraction sockets with immediate or early loading. To evaluate the clinical outcomes of immediately placed anodized tapered implants in consecutive patients with at least 10 years of follow up. This retrospective analysis evaluated outcomes of 61 consecutive patients who received 89 tapered implants with an anodized implant body and machined collar. Implants were placed in fresh extraction sites and functionalized using an immediate- or early-loading protocol. Outcome measures included survival, marginal bone level change (ΔMBL), and papilla index. The 10-year cumulative survival rate was 100%. ΔMBL at the 10-year follow up was -0.86 ± 2.10 mm. At 10 years, patients had mesial and distal papilla index scores of 2 or 3 for 95.9% and 87.8% of implants, respectively. When used for immediate placement and immediate- or early-loading protocols, this implant produced excellent long-term hard- and soft-tissue outcomes.
