A 1.5-year randomized controlled trial comparing standard-sized implants and two diameters of mini-implants immediately loaded by mandibular overdenture: radiographic outcomes, short-term survival, and success rate.

ABSTRACT:

Objective

This study aims to evaluate the marginal bone level changes (MBLC), survival, and success rate of 4 mini-implants (MIs) of two different diameters versus two standard-sized implants (SIs) that were loaded functionally and immediately by a complete mandibular denture.

Materials and methods

The study comprised 29 participants with conventional complete dentures; they were randomly allocated into three groups. Group S included 11 participants who received two SIs of 3.75 mm diameter, group M3 included 8 participants who received four MIs of 3 mm diameter, and group M2.5 included 10 participants who received four MIs of 2.5 mm diameter. MBLC was evaluated on each implant's mesial and distal sides after 18 months of loading. A paired t-test and one-way ANOVA were used f
