Sinus Lift: How DVT Diagnostics and Digital Planning Make Technique Selection Reliable.

Q: Why is DVT essential for sinus lift?

The maxillary sinus has anatomical variability: septa, varying wall thickness, and mucosal changes cannot be reliably assessed on 2D radiographs. DVT provides the data for technique selection (internal vs. external), bone window planning, and assessment of Schneider's membrane perforation risk.

Q: What is the difference between internal and external sinus lift?

In internal sinus lift, the sinus floor is elevated from below through the implant bed — suitable for residual bone height ≥ 5 mm. In external sinus lift, a bone window is created laterally and augmentation material is placed directly — necessary for residual bone height < 5 mm. DVT measurement of residual bone height determines the technique.

Q: How long is the healing period after sinus lift?

After external sinus lift, healing typically requires 6–9 months before implant insertion. With internal sinus lift and simultaneous implant placement, this waiting period is eliminated. DVT follow-up imaging after 6 months objectively documents augmentation material integration.

Q: Can sinus lift be combined with bone augmentation?

Yes. In severe bone deficiency in the maxillary posterior region, sinus lift and GBR (Guided Bone Regeneration) can be combined. Digital planning coordinates both procedures and optimizes augmentation material volume.

Sinus lift is the most common augmentation method in the maxillary posterior region. The choice between internal and external technique depends on DVT-measured residual bone height — not operator preference. The Institute explains why 3D diagnostics and digital planning make the difference.

Kurz erklärt

A sinus lift is necessary when there is insufficient bone in the upper jaw posterior region for an implant. CBCT measurement of residual bone height determines the technique — and thus the effort, healing time, and costs.
