Long-Term Stability of the Use of Patient Specific Implants in Orthognathic Surgery: A Systematic Review.
Synthesis in International dental journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
INTRODUCTION AND
aimThis systematic review aimed to evaluate the long-term stability of patient-specific implants (PSIs) in orthognathic surgery.
methodsThe review was conducted based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. A systematic search including an electronic search of numerous databases with keywords, manual and reference searches was performed. The search results were evaluated and underwent 2 rounds of elimination, first by title and abstract and second by fulfilling the 6 predetermined criteria. The included studies underwent the final systematic review.
resultsSix studies with a total of 171 subjects were included in the final review. The long-term stability of the use of PSIs in orthognathic surgery ranged from 0.27 mm to 0.5 mm for the x-axis and 0.3 mm to 1.07 mm for the y-axis. The mean change was 0.1°, 0.5° and 0.2° for the pitch, roll and yaw, respectively. The absolute mean difference of the SNA angle was 0.57°. The mean duration of operation for using PSIs was shorter than the use of conventional miniplates in orthognathic surgery by 15.7%. Complications and reoperation rates when using PSIs in orthognathic surgery were reported to be 0 in 3 studies and not reported in the other 3 studies.
conclusionThe results of this systematic review indicate that PSIs demonstrate clinically acceptable stability over the medium-to-long term and represent a reliable method of fixation in orthognathic surgery. Additional high-quality studies with standardised methodology and longer follow-up period of more than 24 months are recommended. CLINICAL RELEVANCE: This systematic review highlights the high level of long-term stability when using PSIs in orthognathic surgery in terms of bodily movements, complications and reoperation rates. Oral and maxillofacial surgeons and biomechanical engineers may now have a more comprehensive and deeper understanding of the use of PSIs in the long term, which can assist them in choosing the method of fixation in orthognathic surgery.
