Overlap with other reviews

Reviews that include the same primary studies are not independent evidence. Shared counts match studies by PMID, DOI or NCT, and otherwise by author and year (a probable match). Only the non-Cochrane dental reviews have study lists, so overlap with Cochrane reviews is not counted yet.

Review question

ElementPlanned (methods)Found (results)
PopulationPatients undergoing orthognathic surgery for dentofacial deformities1317 patients (PSI 665; splints 652) in 30 studies (n=30); bimaxillary (n=19), mandible only (n=4)
InterventionPSI workflows: patient-specific cutting/repositioning/drilling guides and/or customized osteosynthesis platesPSI workflows (n=30)
ComparisonCAD/CAM occlusal splint or wafer-based workflowsCAD/CAM splints (n=30)
OutcomesAxis-specific translational and rotational accuracy (primary); operative time and postoperative complications (secondary); long-term stability not pooledLinear accuracy (axes n=13-15 comparisons; combined n=14 studies), angular accuracy (n=6), complications (n=9), operative time (n=7)
Study designsComparative clinical studies (RCTs and observational comparative studies, at least 5 patients per arm)12 RCTs and 18 cohort studies (16 retrospective, 2 prospective); 21 pooled, 9 narrative
TimingNot specifiedPostoperative imaging from 3 days to 1 month
