In this work, we report six new supermassive black hole mass measurements of massive early-type galaxies from stellar kinematics, which were extracted from adaptive optics-assisted SINFONI and MUSE observations. We combine the stellar kinematics with HST photometry to build DYNAMITE triaxial Schwarzschild orbit-superposition models. Our Schwarzschild models can recover the complex triaxial features of the galaxies and constrain the black hole masses of all six galaxies. We find that strong triaxial kinematic features can bias the mass measurements and correct for this effect. The derived black hole masses are (1.14^+0.41^_-0.6_})x10^9^M+{sun}_ for NGC 3706, (1.19^+1.34_-0.80_)x10^9^M_{sun}_ for NGC3923, (1.14^+1.08^_-0.95_)x10^9^M_{sun}_ for NGC4261, (4.68^+2.99^_-4.26_)x10^9^M_{sun}_ for NGC 4636, (3.51^+3.37^_-2.57_)x10^9^M_{sun}_ for IC 4296, and (2.43^+1.53^_-1.65_)x10^9^M_{sun}_ for IC 4329 at 3{sigma} confidence level. We compare our measurements with published results from axisymmetric Schwarzschild modelling and with our Jeans Anisotropic Models (JAM), and obtain mostly consistent black hole masses. Most of our black hole mass estimates can be well constrained using only MUSE observations. All of our mass measurements are in agreement with local black hole scaling relations.2026A&A...712A.105Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/712/A105CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/712/A105https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/712/A105http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/712/A105https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/712/A105https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/712/A105http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/712/A105GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/712/A105/list (List of MUSE and SINFONI datacubes)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/712/A105/list?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/712/A105/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/712/A105/list?GETtext/xml+votable180.050000true177.75743-28.806210.0055555555555555566/24733 26313 27714 38356 43806 43828 43877https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/712/A105?format=asciiOpticalInfrareddefaultJ/A+A/712/A105/listList of MUSE and SINFONI datacubesrecnoRecord number assigned by the VizieR team.
