Abstract
PURPOSE: This study was conducted to investigate one-piece narrow-diameter implants installed in maxillary lateral and mandibular incisor sites using immediate nonfunctional loading. MATERIALS AND METHODS: In this 10-year clinical trial study, 42 narrow-diameter (3.0-mm) one-piece implants for 35 patients were inserted. Clinical and radiographic measurements were recorded in 10 years and analyzed statistically using t test. RESULTS: A total of 26 patients (20 females and 6 males) with 30 implants were available for the 10-year follow-up. The 10-year implant survival rate was 100%. A statistically significant mean marginal bone loss was observed between 12 months and 10 years (0.18 ± 0.29 mm). The mean pocket depth increase was statistically significant (0.68 ± 0.83 mm). No bleeding on probing was observed around 90% of the implants. Full-mouth plaque index was registered at 20% of the implants. CONCLUSION: The results obtained in this analysis suggest that modest marginal bone loss was observed around the implants. One-piece narrow-diameter implants (Maximus 3.0; BioHorizons) can predictably restore missing maxillary lateral incisors and mandibular incisors in cases of careful patient selection.
