This study evaluated the effect of metal and PEEK (Polyether ether ketone) sleeves on implant accuracy compared to planned virtual positioning. Using CT scans and virtual planning software (coDiagnostiX), a STRAUMANN\u00ae RC BLT 4.1 x 10 mm implant was planned in the element 36 region of a partially edentulous patient (Ethical approval #5.879.848). Twenty surgical guides of hemi-arch were printed (10 with metal sleeves, 10 with PEEK sleeves) and tested using a master model. Implants were inserted through static guides, and the positional deviations were analyzed by comparing planned versus inserted implants using angular, coronal, and apical metrics. Statistical analysis showed significantly lower angular deviation in the PEEK sleeve group (57.2% lower than metal sleeves, p &lt; 0.001), indicating greater precision. However, coronal deviation was significantly higher in the PEEK group (66.3% higher than metal sleeves, p = 0.006). No significant differences were found in apical deviation (p = 0.186). These findings suggest that the choice of sleeve material significantly impacts guided surgery accuracy, with PEEK sleeves offering superior angular precision but higher coronal deviation compared to metal sleeves.<\/jats:p>","DOI":"10.1590\/0103-644020256696","type":"journal-article","created":{"date-parts":[[2026,6,26]],"date-time":"2026-06-26T10:51:00Z","timestamp":1782471060000},"source":"Crossref","is-referenced-by-count":0,"title":["Accuracy
