Cost Effectiveness of Two Short Implants Versus One Short Implant With a Cantilever in the Posterior Region: 7.5-Year Follow-Up of a Randomised Controlled Trial.

ABSTRACT:

Aim

To compare long-term clinical and radiographic outcomes of a single short implant (6 mm) supporting a cantilevered restoration versus two adjacent short implants with non-splinted single crowns over a 7.5-year follow-up and determine which approach is more cost effective.

Materials and methods

A total of 36 patients with at least a two-tooth gap in the posterior region were randomised to receive either one short implant with a cantilever prosthesis (ONE-C) or two short implants with individual crowns (TWO). Fixed restorations were placed 3-6 months post implantation, and patients were evaluated at baseline and at 6 months and 1, 3, 5 and 7.5 years. Kaplan-Meier curves, mixed-effects models and cost-effectiveness models were used to compare the groups.
