Optimal fiducial marker distribution for navigated tilted implants in edentulous maxillae: an in vitro study.
Article in BMC oral health, 2025. 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
backgroundTo determine the most appropriate fiducial markers distribution strategy in navigation surgery for three different tilted implant scenarios by comparing the target registration error (TRE) of tilted implants in fully edentulous maxillae.
methodsThe cone beam computed tomography scanned a maxillary edentulous model with 16 bone-anchored mini-screws (8 for registration and 8 for target registration error measurement), which was further imported into the navigation system for registration and target registration measurement. Each of the 5 strategies was performed six times, and the measurements were repeated twice around 4 target points each time. A mixed linear model was utilized for data analysis.
resultsRegistration distribution, measurement site, and their interaction had a statistically significant influence on TREs (P = 0.010, 0.000, and 0.001, respectively). Two markers on the anterior alveolar crest, 2 in the buccal of the anterior alveolar ridge, and 2 on both sides of the maxillary tuberosity can realize the minimal TREs for tuberosity-pterygoid-palatine implant (TPP) at both coronal and apical points. No significant TRE differences were found for apical points of mesial tilted implant in 'all on four' and zygomatic implants among the 5 registration strategies.
conclusionsFor TPPs, incorporating fiducial markers on maxillary tuberosity for registration can help reduce the TRE in dynamic navigation.
