# ProTaper Ultimate vs WaveOne Gold Dentsply Sirona [TR](https://endo-guide.app/tr/compare/protaper-ultimate-vs-waveone-gold) ## ProTaper Ultimate™ Dentsply Sirona The Ultimate Evolution [View protocol →](https://endo-guide.app/system/protaper-ultimate) ## WaveOne Gold® Dentsply Sirona Single File Reciprocation [View protocol →](https://endo-guide.app/system/waveone-gold) Clinical Tip ProTaper Ultimate for a gold multi-file approach in complex anatomy. WaveOne Gold for reciprocating single-file efficiency in routine cases. ## When to choose which Choose ProTaper Ultimate when - you want more of the canal wall touched: Ultimate to F2 left 17.1 % of mandibular molar walls unprepared against 22.5 % for WaveOne Gold Primary (PMID 41964818) - torsional strength at the ISO test point matters more to you than bench fatigue life: Ultimate F2 broke at 1.45 Ncm against 1.10 Ncm for the Primary (PMID 41964818) Choose WaveOne Gold when - the canal is curved and bench fatigue life is the concern: the Primary reached 1,883.10 cycles at 35 °C against 726.70 for Ultimate F2 (PMID 41964818) - you want one file per canal with shaping equal to Ultimate in curved mesiobuccal canals: transportation and centring did not differ at 3, 5 or 7 mm in 25 to 40 degree maxillary molar roots (PMID 41685849) - you pair the file with sonic activation and debris extrusion worries you: the WaveOne Gold plus sonic combination extruded the least debris of nine combinations tested (PMID 41094147) ## What the comparative evidence shows 3 comparative full-text studies read for this pair Three comparative full texts were read for this pair: one micro-CT shaping study in maxillary molars, one debris-extrusion study and one combined bench and micro-CT series in mandibular molars. Ultimate is a multi-file rotary system with an off-centred parallelogram cross-section and file-specific heat treatments; WaveOne Gold Primary is a single reciprocating file with a parallelogram cross-section and a 7 % apical taper. Three further comparative papers, on pericervical dentin and smear layer, on severely curved canals and on rotary against manual use, are paywalled and were not read, so the read set is thinner than for the other ProTaper pairs. On shaping, 42 mesiobuccal canals of maxillary molars with 25 to 40 degrees of curvature showed no difference in transportation or centring between WaveOne Gold, Ultimate and TruNatomy at 3, 5 or 7 mm, and no canal was displaced more than 0.2 mm (PMID 41685849). In 50 mandibular first molars, Ultimate to F2 and the Primary produced the same volume increase, but the Primary left more of the wall untouched (22.5 % against 17.1 %) and Ultimate showed the highest transportation of five systems at the 6 mm level of the mesial canals (PMID 41964818). On mechanics, the same series found the Primary far ahead on cyclic fatigue at 35 °C in a 60-degree steel canal (1,883.10 cycles against 726.70), Ultimate F2 ahead on maximum torque (1.45 Ncm against 1.10 Ncm) and on angular deflection (398.87 degrees against 310.87), and Ultimate F2 the stiffest of the five files in a 60-degree bending test (PMID 41964818). The authors present these as whole-system contrasts and warn that taper, cross-section and kinematics are confounded. On debris, 135 straight mandibular premolars prepared at 35 °C showed no difference in apical extrusion between Ultimate to F3, WaveOne Gold to Medium and a third rotary system, while passive ultrasonic activation extruded more than sonic or conventional irrigation whichever file was used; the WaveOne Gold plus sonic combination extruded the least (PMID 41094147). Nothing in the read set compares the two files on postoperative pain, healing, dentinal defects or retreatment. ## Head to head | Axis | ProTaper Ultimate | WaveOne Gold | What the studies show | | --- | --- | --- | --- | | Cyclic fatigue (bench) | 726.70 cycles at 35 °C in a 60° canal | 1,883.10 cycles, highest of five systems | One static test at manufacturer settings, 25-tip files (PMID 41964818) | | Torsion and bending | Higher maximum torque (1.45 Ncm) and larger deflection; stiffest of five files in bending | Lower maximum torque (1.10 Ncm); smaller deflection | ISO-style torsion at 3 mm, bending to 60° (PMID 41964818) | | Transportation and centring | No difference from WaveOne Gold in maxillary MB canals; highest transportation of five at 6 mm in mandibular mesial canals | No difference from Ultimate in maxillary MB canals | Two micro-CT studies; no canal displaced over 0.2 mm in the maxillary study, while mean mid-root values in the mandibular study ran to 0.48 mm (PMID 41685849, PMID 41964818) | | Wall contact and debris | 17.1 % of walls unprepared; debris equal to WaveOne Gold | 22.5 % of walls unprepared, the highest of five; least debris when paired with sonic activation | Molar micro-CT (PMID 41964818); premolar extrusion at 35 °C (PMID 41094147) | ## Frequently asked 01 Which is more fatigue resistant, ProTaper Ultimate or WaveOne Gold? Answer In the one bench comparison read for this page, WaveOne Gold Primary survived about two and a half times as many cycles as Ultimate F2 at 35 °C in a 60-degree canal (PMID 41964818). - 01 Ultimate F2 broke at a higher torque and was stiffer in bending in the same series. 02 Do they shape curved canals differently? Answer In curved maxillary mesiobuccal canals they did not differ in transportation or centring (PMID 41685849). - 01 In mandibular molars the Primary left more wall untouched and Ultimate transported more at one mid-root level (PMID 41964818). 03 Which extrudes less debris? Answer Neither, on its own: the two files extruded the same amount in straight premolars. - 01 The activation method mattered more, and WaveOne Gold with sonic activation extruded the least of nine combinations (PMID 41094147). 04 What are the motor settings side by side? Answer ProTaper Ultimate runs at 400 rpm with a torque window of 4. - 01 0 to 5. - 02 2 Ncm per its IFU; the studies read here ran it at 4 Ncm. - 03 WaveOne Gold runs on the WaveOne ALL preset reciprocation programme. - 04 The full protocol pages list both. ## References 1.
