Minimally invasive management of lower midline diastema: A case report and literature review.
Review in Medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
rationaleMidline diastema is an unpleasant condition that affects a patient's smile and causes significant aesthetic concerns. Treating diastema and achieving the desired aesthetics, function, and harmony can be challenging without invasive treatment. This case report demonstrates a minimally invasive approach to closing a lower midline diastema. PATIENT CONCERNS: A 38-year-old female patient presented to the dental clinic at King Khalid University with the primary complaint of a "large space in the lower front tooth region." Her medical history indicated no significant health concerns. DIAGNOSES: The patient was diagnosed with localized periodontitis, stage III, grade B. She presented with a Miller class III gingival recession at the lower central incisors, an aberrant frenum, a decreased width of keratinized gingiva, and a midline diastema of 6 mm.
interventionsA free gingival graft is used to increase the width of the keratinized gingiva, followed by the placement of a zirconia resin-bonded bridge to close the space. OUTCOMES: The treatment yielded a satisfactory outcome, as evidenced by an increase in the width of keratinized gingiva from 1 mm at baseline to 5 mm at 4 months and a gain of 1 to 2 mm in clinical attachment level. Two months following surgery, complete closure of a 6-mm lower midline diastema was successfully achieved using a zirconia resin-bonded bridge. LESSONS: The use of a free gingival graft effectively increases the width of the keratinized gingiva. A resin-bonded bridge offers satisfactory aesthetics and functionality, providing a conservative treatment that makes it a favorable option for closing lower midline diastema compared with more invasive and time-consuming procedures, such as bone grafting or orthodontic treatment.
