1 · What the graph read from it

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.

2 · The registry

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

Objective: This study aimed to evaluate the use of a stainless-steel fixed retainer for post-orthodontic retention in patients with labiolingual alveolar bone resorption in the mandibular anterior segment. Methods: Three mandibular anterior segment models (with or without labial or lingual alveolar bone resorption) with 0.5-mm-diameter retainers bonded to all teeth were constructed. Two occlusion schemes were simulated: a 285.3 N force applied to four mandibular incisors (incisor biting) and a 93 N force applied to the left canine (laterotrusion). The tooth displacement and stress distribution in the periodontal ligament (PDL), retainer, and composite were evaluated. Results: Compared to no resorption, labial bone resorption significantly increased tooth displacement and PDL stress concentration in the central incisors during incisor biting, whereas lingual resorption had a greater effect on the guiding canine during laterotrusion. The retainers were susceptible to stress concentrations in the resin-uncovered area, mesial region of the lateral incisors under incisor biting, and mesial region of the guiding canine under laterotrusion. For the composite, the composite-retainer interface was prone to stress concentrations, especially in the mesial or distal extremes of the adhesive composite of the incisors. Conclusions: A 0.5-mm-diameter stainless-steel lingual retainer bonded on all teeth is a clinically acceptable retention procedure for patients with lingual bone resorption in the lower anterior region. However, it should be used more cautiously for patients with labial bone resorption as it exposes the lower central incisors to a greater risk. Excessive stress on the retainer and composite due to the occlusion force may lead to unwanted tooth movement, necessitating closer monitoring.
