CBCT Analysis of Bone Structure
CBCT Analysis of Bone Structure
Material selection between titanium and zirconia begins with 3D analysis of bone. CBCT provides data on bone density, height, and width that are crucial for implant dimensioning. With zirconia implants, apical anchoring length is particularly critical — digital planning makes this requirement precisely measurable.
Angulation Planning for One-Piece Systems
One-piece zirconia implants do not allow angulation correction at the abutment. Digital implant planning with overlay of CBCT data and intraoral scans is therefore mandatory for zirconia — not optional. Deviations from the planned axis cannot be corrected after insertion.
CAD/CAM Fabrication of Suprastructure
Whether titanium or zirconia: the prosthetic restoration is digitally designed and milled. CAD/CAM-fabricated crowns and bridges on zirconia implants achieve a fit accuracy that hand-crafted work cannot reproducibly achieve. The digital process chain from scan through design to fabrication is fully documentable.
Vergleich
| Kriterium | Titanium | Zirconium Dioxide |
|---|---|---|
| Material Class | Metal (Pure titanium Grade 4 / Grade 5 Ti-6Al-4V) | Oxide ceramic (Zirconium dioxide, Y-TZP) |
| X-ray Density | High X-ray density — artifacts in CBCT possible | Lower X-ray density — improved CBCT assessability |
| Digital Planability | Fully CAD/CAM-compatible, both system types | Fully CAD/CAM-compatible, one-piece systems require more precise angulation planning |
| Surface Topography | SLA, SLActive, hydrophilic surfaces — extensively documented | Sandblasted, acid-etched — growing data pool |
| Long-term Data | Gold standard: > 30 years clinical documentation | Growing: 5–10-year data available, meta-analyses limited |
| Fracture Behavior | Ductile — bends before breaking | Brittle — fracture without warning possible |

Kurz erklärt
Zircon implants are a metal-free alternative to titanium implants — made from high-strength ceramic. They are aesthetically inconspicuous, biocompatible, and particularly relevant for patients with metal sensitivity or high aesthetic demands. The evidence is good, but not yet as extensive as with titanium.
Wann ist das relevant?
- You have metal sensitivity or don't want metal in your body
- Your implant is in the visible area and you want maximum aesthetics
- Your dentist offers zircon and you want to understand the differences
- You want to know if zircon is as durable as titanium
