The presence of One or Two Adjacent Teeth may not impact Marginal Bone Level Changes Around Dental Implants suggests a new study published in the Clinical Oral Implants Research.

A study was done to compare mean bone level (mBL) changes around dental implants with one or two adjacent teeth after a function time of ≥10 years. One hundred thirty three periodontally compromised patients (PCPs) with 551 implants enrolled in supportive periodontal care (SPC) were screened. Implants were categorized either into group TIT (tooth-implant-tooth) or into group TIG (tooth-implant-gap). MBL changes from delivery of restoration (i.e., baseline) to follow-up were calculated in millimeters and compared between im-plants and adjacent teeth. Survival rates and the need for surgical interventions during SPC were recorded.

Results:

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).

High tooth and implant survival rates were observed in PCPs. The presence of one or two adjacent teeth seemed to have no impact on marginal bone level changes.
