Exploratory investigation of pain threshold in the facial and cervical regions following dental implant surgery.
Article in Oral and maxillofacial surgery, 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
purposeThe pathogenic mechanisms and variations in individual pain susceptibility underlying neuropathic pain associated with dental implant surgery have not been fully elucidated, and objective evaluation methods for such pain remain unestablished. The objective of this study was to identify exploratory trends in subclinical sensory changes by evaluating changes in pain thresholds following dental implant surgery.
methodsThe subjects included 76 outpatients who visited the Department of Fixed Prosthodontics at Osaka University Dental Hospital for dental implant surgery. Pain thresholds were recorded before and after surgery within the regions innervated by the second and third divisions of the trigeminal nerve and the upper cervical plexus. Measurements were performed using a computer-controlled thermal sensory analyzer (PATHWAY, Medoc Co. Ltd).
resultsThe decline of the pain threshold event detected by the thermal stimulation on the operating side occurred in 28.57-48.57%, 10.48-25.90%, 1.40-10.36% and 0.09-1.38% of subjects at 1, 2, 4, and 12 weeks post-surgery, respectively.
conclusionsThis prospective cohort study evaluated the impact of dental implant surgery on pain thresholds. The findings suggest that a significant proportion of patients may experience transient post-surgical sensory changes, characterized by a decline in their pain threshold following surgery, even in the absence of subjective pain complaints.
