Three-Dimensional Prospective Evaluation of Piezocision-Assisted and Conventional Rapid Maxillary Expansion: A Controlled 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
backgroundPiezocision-assisted orthodontics (PAO) is considered one of the modern techniques aiming at reducing the treatment time and overcoming some limitations of orthodontic treatment. The use of piezocision as an adjunct in the treatment of posterior crossbite is limited, so additional research in this area is required.
aimTo three-dimensionally compare the skeletal and dental effects produced by piezocision-assisted rapid maxillary expansion (PARME) and conventional rapid maxillary expansion (RME) using cone beam computed tomography (CBCT). MATERIALS AND
methodsThis prospective controlled study comprised 14 consecutive non-syndromic patients with posterior crossbite. In 7 patients (mean age = 16.1 ± 0.3 years), PARME was used to correct the crossbite; whereas in the remaining 7 (mean age = 15.9 ± 0.5 years), RME was done. Cone beam computed tomography (CBCT) scans were performed before expansion (T1) and 3 months later after expansion (T2) to compare the skeletal and dental effects produced by the two expansion techniques. Transverse skeletal, dentolinear, and dentoangular variables at the level of maxillary first and second premolars and maxillary first molars were measured and compared within and between groups using the appropriate statistical test.
resultsFor the transverse skeletal variables, PARME showed a non-significant increase; whereas, RME showed a significant increase. Regarding the dentolinear measurements, a significant increase in coronal widths and an insignificant increase in apical widths was seen in PARME, whereas, the RME showed a non-significant increase for both coronal and apical widths. Non-significant decreases (protrusion of teeth) in the dentoangular measurements were seen in both groups. Between-group comparisons showed a non-significant difference except for the dentolinear coronal widths.
conclusionPARME is effective in treating posterior crossbite. Because of the more dental expansion produced by PARME as compared to the conventional RME, PARME should be limited only to mild or moderate not severe forms of palatal constriction. The available evidence regarding the effectiveness of corticotomy- and/or piezocision-assisted maxillary expansion for correction of posterior crossbite is limited and inadequate.
