Mini-implant placement under existing removable partial dentures decreased the mobility of remaining teeth in a randomized controlled 3-year clinical trial.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesLongitudinal stability values of teeth after strategic implant insertion under existing removable partial dentures (RPD) are lacking. This explorative evaluation of a 3-year randomized controlled trial on strategic min-implants (MI) aims to estimate the stability changes of the remaining teeth and the tooth survival rates under different MI loading conditions. MATERIALS AND
methodsPartially edentulous study participants of a university clinic and three private practices with inadequately supported RPDs received strategic MIs (diameter 1.8-2.4 mm). According to the randomization the MIs were either immediately loaded in group A or delayed loaded in group B. The longitudinal changes of Periotest values (PTV) for teeth were compared between groups using mixed models adjusted by sex, age, jaw, tooth site, center, and baseline PTVs. The tooth survival was estimated with Kaplan-Meier analyses and group differences were analyzed using Cox regression.
resultsAltogether 232 MIs were placed under 48 mandibular and 31 maxillary RPDs with a total of 255 remaining teeth in both jaws. The initial median PTV of 9.5 in group A and 8.0 in group B decreased to 5.0 in group A and 2.0 in group B at the 3-year follow-up. In the fully adjusted model the tooth mobility reduction revealed 5.3 PTV units (95% CI: 3.5-7.2) in group A and 7.6 PTV units (95% CI: 5.4-9.9) in group B without inferiority of any group (P = 0.122). The 3-year tooth survival rates were 88% in group A versus 92% in group B without relevant group differences (P = 0.338).
conclusionStrategic MIs under existing RPDs in persons with severe reduced dentitions decreased the mobility of the remaining teeth independent from implant loading modus. Further tooth loss can emerge despite of relieving the remaining dentition by the MIs. STATEMENT OF CLINICAL RELEVANCE: Mini-implants as supplementary abutments can restabilize loose teeth in jaws with RPDs and unfavorable tooth distributions. CLINICAL
