Comparison

Straumann BLX vs TLX: bone level and tissue level compared

BLX and TLX share the X-Line design, Roxolid® and SLActive®. The difference is where the implant ends: at the bone (BLX) or through the gum (TLX).

What actually differs
  • Same design family, material and connection type.
  • The implant–abutment join sits at bone level (BLX) or above it (TLX).
  • The choice depends on site, soft tissue and restorative plan.

Highlighted rows differ. A design difference is not evidence that one implant gives better results for you. No scores and no winner. The choice is a clinical and restorative decision.
