Straumann Surgical Guides: BLT, BLX, and TLX — What Your Designer Needs to Know

Straumann is the benchmark. When clinicians talk about implant systems, Straumann is usually the first name and often the standard against which everything else is measured. There's a reason for that — decades of longitudinal data, consistent prosthetic platform architecture, and a surface technology that predictably delivers osseointegration.

But "it's Straumann" is not a reason to assume any guide designer can handle the case. Straumann's current portfolio — BLT, BLX, and TLX — includes systems with fundamentally different surgical protocols and guide requirements. A designer who treats a BLX like a BLT will produce a guide that fights you in surgery.

This article covers what actually matters when you order a surgical guide for Straumann implants.

Why Straumann Guides Demand Platform-Specific Expertise

Straumann isn't one system anymore. Between the legacy Bone Level (BL), the current Bone Level Tapered (BLT), the high-primary-stability BLX, and the newest TLX, you're looking at four different surgical protocols under one brand umbrella.

Each system has its own drill sequence, its own sleeve dimensions, and its own insertion behavior. The BLX, for example, uses a progressive thread design that achieves high torque in challenging bone — but the osteotomy prep is intentionally undersized compared to BLT. If the guide sleeve is calibrated for BLT drill diameters, you lose the BLX's primary stability advantage.

We maintain separate, verified digital implant libraries for every current Straumann platform. The details are what make your surgery predictable.

Straumann Implant Lines We Support

Bone Level Tapered (BLT)

The current-generation standard.

• SLActive surface (hydrophilic, chemically active for accelerated healing)
• CrossFit connection with 4 indexing positions
• Roxolid (titanium-zirconium alloy) and Grade IV titanium options
• Diameters: 2.9mm (Roxolid only), 3.3mm, 4.1mm, 4.8mm
• Lengths: 6mm to 14mm
• Color-coded platforms: Narrow CrossFit (NC), Regular CrossFit (RC), Wide CrossFit (WC)

The BLT's CrossFit connection allows four rotational positions for the abutment. During guide design, we verify that the planned rotational position aligns with optimal prosthetic emergence — especially critical in anterior cases where the screw-access channel position determines whether you get an aesthetic result or a facial perforation.

BLX

The immediate-loading specialist.

• Designed for high primary stability even in compromised bone
• Fully tapered body with deep apical threads
• Progressive thread design: aggressive at the apex, gentler at the crest
• Diameters: 3.5mm, 4.0mm, 4.5mm, 5.0mm, 5.5mm, 6.5mm
• Lengths: 6mm to 14mm
• TorcFit connection (new geometry, NOT CrossFit-compatible)

BLX is fundamentally different from BLT in guide design. The osteotomy is intentionally undersized — the implant cuts its own final path. The guide sleeve must accommodate the specific BLX drill sequence (VeloDrill), which has fewer steps than the BLT protocol. Using BLT sleeves on a BLX case means the osteotomy is too wide, and you lose the primary stability that makes immediate loading possible.

TLX

The tissue-level evolution.

• Combines the surgical simplicity of tissue-level implants with modern guided surgery
• Machined collar transitions directly to SLActive surface
• Designed to eliminate the implant-abutment microgap at bone level
• Diameters: 3.3mm, 4.1mm, 4.8mm
• Lengths: 6mm to 14mm
• ProFit connection (unique to TLX)

TLX is Straumann's answer to clinicians who prefer tissue-level placement but want guided surgery precision. The guide sleeve must account for the machined collar height — the implant seats deeper than a standard BLT at the same platform diameter.

How We Design Guides for Straumann (Step by Step)

Step 1: Upload and System Identification

Upload your files through the SurgicalGuide.pro dashboard:

• CBCT scan in DICOM format (0.2mm voxel size or smaller recommended)
• Intraoral scan in STL or PLY (Medit, 3Shape, iTero, Primescan — all accepted)
• Specify your exact Straumann system: BLT, BLX, or TLX — plus platform size and preferred diameter range

"Straumann 4.1" is ambiguous. Is it a BLT RC 4.1, a BLX 4.0, or a TLX 4.1? Each requires different sleeve engineering.

Step 2: Anatomical Mapping

We merge CBCT and surface scan data, then trace all critical structures:

• Inferior alveolar nerve canal and mental foramen location
• Maxillary sinus floor and septa
• Bone density assessment (Hounsfield units per region)
• Existing restorations and implant positions

For BLX cases specifically, we pay extra attention to bone density mapping — since BLX is often chosen for type III-IV bone, we verify that the planned insertion torque is achievable.

Step 3: Prosthetic-Driven Placement

Implants from our verified Straumann libraries are positioned with restorative outcomes driving every decision:

• Screw-access channel through the cingulum or central fossa
• Minimum 2mm clearance from the inferior alveolar nerve
• Minimum 1.5mm buccal and lingual bone thickness
• Platform depth matched to your preferred protocol
• CrossFit or TorcFit rotational orientation verified for prosthetic predictability

Step 4: Guide Engineering

System-specific sleeve design:

• Sleeve inner diameters matched to the BLT, BLX (VeloDrill), or TLX drill sequence
• Multi-step drill stops calculated for the complete osteotomy protocol
• For BLX: intentionally undersized osteotomy accounted for
• Fixation pin positions for cross-arch stability
• Inspection windows for visual seating verification

Step 5: Interactive Review

3D review link accessible on any device:

• Rotate and zoom all implant positions
• Verify nerve distances and bone measurements
• Check prosthetic emergence angles

Unlimited revisions. No extra charge.

Step 6: Delivery

After approval:

• Print-ready STL of the surgical guide
• System-specific drilling protocol (BLT, BLX VeloDrill, or TLX sequence)
• Sleeve specification sheet with matching component references
• Complete case documentation

Straumann coDiagnostiX vs. Independent Design

Straumann partners with coDiagnostiX for their guided surgery workflow. It's powerful planning software — used by many top clinicians worldwide. Here's why some practices choose to work with us instead:

Mixed-system freedom: If you place Straumann BLX in the posterior and Nobel Active in the anterior, you need one unified plan. We handle everything in one template.

No software investment: CoDiagnostiX requires licensing and training. We handle the planning — you focus on surgery.

Speed: Standard delivery in 2-3 days. Express in 24 hours.

Legacy integration: Placing new BLX implants next to old ITI Bonefit fixtures from 1998? We can incorporate legacy positions.

Real Talk: When Straumann Guides Get Complicated

BLX in Soft Posterior Bone

BLX is designed to achieve high torque in soft bone — but the guide must be engineered for the undersized VeloDrill protocol. If the sleeve allows even 0.3mm more lateral movement than intended, insertion torque drops below the threshold for immediate loading. We design BLX sleeves with tighter tolerances than standard.

Full-Arch with Mixed BLT and BLX

An All-on-4 using tilted BLX posteriorly (for primary stability in poor bone) and BLT anteriorly (for prosthetic platform versatility) requires two different drill protocols in one guide. We verify every position against the matching drill sequence.

Narrow Diameter BLT (2.9mm Roxolid) in Mandibular Incisors

The 2.9mm Roxolid BLT is a specialized implant for narrow ridges. The titanium-zirconium alloy provides superior fatigue strength at small diameters — but the guide must deliver extreme precision. We recommend bone-supported guides for these cases to eliminate tissue-borne instability.

TLX Transgingival Depth Planning

TLX implants must be placed so the machined collar transitions at the correct vertical position relative to the soft tissue margin. We calculate the optimal insertion depth based on your tissue thickness and verify it against the guide's depth stop.

FAQ

Do you support all Straumann implant systems?

Yes. We maintain verified digital libraries for BLT (NC, RC, WC), BLX (all diameters), and TLX in every available diameter and length. We also support legacy BL and Standard Plus for integration planning.

Can I use your guide with Straumann's guided surgery cassette?

Absolutely. Our guides are designed with sleeve dimensions that match Straumann's guided surgery instruments — BLT guided cassette, BLX VeloDrill setup, or TLX instruments.

What about Roxolid vs titanium — does it affect guide design?

The implant material doesn't change sleeve specs. However, the 2.9mm Roxolid BLT has a unique narrow platform (NC) that requires specific narrow sleeves. We automatically select correct components based on your specification.

What if I place Straumann and another brand in the same arch?

We design mixed-system cases routinely. Straumann BLX at one site, Nobel Active at another — all in one surgical template with the correct sleeves for each.

How do I get started?

Upload your CBCT and STL files through your dashboard at SurgicalGuide.pro. Select Straumann as your implant system and specify the exact platform (BLT, BLX, or TLX). We take it from there.
