What is the TLZ-IB with Metal Substructure, and how is it different from the standard TLZ-IB?
The TLZ-IB with Metal Substructure is ROE's full-arch, implant-supported fixed bridge built on a titanium framework rather than a full-zirconia core. It combines titanium's proven strength with zirconia's superior esthetics through direct-to-implant engagement that eliminates traditional multi-component complexity.
The key distinction from the standard TLZ-IB Zirconia, which uses a full-zirconia substructure, is the titanium substructure. This engineered metal framework provides a superior strength-to-thickness ratio, making it the option of choice for cases where vertical height is limited or where extra strength is needed. The titanium version trades a small amount of esthetic ceiling for greater rigidity in a thinner profile.
Standard TLZ-IB vs. metal-substructure version:
| Factor | TLZ-IB Zirconia | TLZ-IB with Metal Substructure |
|---|---|---|
| Substructure | Full zirconia | Titanium |
| Prosthetic design | FP1 / FP2 / FP3 | FP3 |
| Best for | All patient types | Extra strength needed, or less than 10 mm vertical space |
| Esthetic rating | 5 out of 5 | 4 out of 5 |
| Wear rating | 5 out of 5 | 5 out of 5 |
| Days in lab | 5 days | 11 days |
It serves as an ideal alternative to traditional zirconia hybrids when maximum strength in a refined profile is essential. To discuss whether a case fits this option, request pricing or send a case.
