Treatment outcomes and short-term stability in adult anterior openbite patients treated with or without extractions: a National Dental Practice-Based Research Network study.

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
objectivesTo investigate whether extractions in adult anterior openbite (AOB) patients lead to improved treatment outcomes and better short-term stability. MATERIALS AND
methodsRecords of extraction (EXT) and nonextraction (NE) adult patients were identified from all patients treated with fixed appliances through the National Dental Practice-Based Research Network. Photographic Openbite Severity Index was used to assess treatment success and stability. Skeletal, dental, and soft tissue treatment outcomes were evaluated using cephalometric analysis.
resultsPretreatment and posttreatment records were collected for 115 patients. Thirty-three were treated with extractions; 82 were treated without extractions. The EXT group was younger, more crowded, and had less previous orthodontic treatment. Success rate of AOB correction in the EXT group was slightly higher (97%) than the NE group (92%) but not statistically different. No significant differences were observed in skeletal outcomes. The EXT group exhibited more lingual tipping and posterior movement of maxillary and mandibular incisors and less extrusion of mandibular incisors. Dental changes in the EXT group were associated with increased nasolabial angle and lip retraction. The small number of patients with AOB relapse did not provide enough power to identify differences in stability between the two groups.
conclusionsOrthodontists have high success correcting AOB with or without extractions. The EXT group displayed more retraction and lingual tipping of incisors as well as increased retraction of soft tissues. Stability of AOB closure was more than 90% for both groups after 1 year, with marginal increases in stability after extractions.
