Presence of One or Two Adjacent Teeth may not impact Marginal Bone Level Changes Around Dental Implants

Eighty seven patients with 142 implants were re-evaluated after a mean observation time of 14.5 ± 3.5 years. The mBL at mesial implant sites in the TIT group increased −0.07 ± 0.92 mm and decreased in the TIG group 0.52 ± 1.34 mm, respectively (95% CI: 0.04/1.14, p= .037). At distal implant sites, the mBL in the TIT group increased −0.08 ± 0.84 mm and decreased 0.03 ± 0.87 in the TIG group, respectively (95% CI: −0.20/0.42, p= .48). The overall implant loss rate was 3.5% (n= 5; 2 TIT, 3 TIG), without a statistically significant difference between the two groups (95% CI: 0.18/7.07, p= .892). Tooth loss rates (TIT: 12.3%, TIG: 12.3%) were not statisticallysignificantly different (OR = 1.00, p= .989).
