Guided vs. Freehand Surgery for All-on-X: Choosing the Right Surgical Approach for Full-Arch Implant Success

All-on-X implant surgery requires precise planning and execution. Whether you’re placing implants freehand or using a surgical guide, the approach you take has a direct impact on esthetics, function and patient satisfaction.

As full-arch treatments become more common, it’s important to understand the pros and cons of guided vs. freehand surgery for All-on-X cases to make the best decision for success. And if you do elect the guided surgical route, it’s essential to know the right surgical guide system to achieve consistent results.

This article compares and contrasts these different surgical approaches and provides key insights that will help you choose the right approach for long-term success in full-arch implant restorations.

Thinking About Transitioning from Freehand to Guided for All-on-X?

Freehand, or skill-based surgery, is a workflow based on analog elements combined with radiography and CBCT to perform implant placement. It’s the more traditional method and can be used in single-unit, multi-unit and full-arch cases.

Although it uses an analog approach in an age of technologically assisted options, there are still situations where it might be favorable to use a guided approach. Let’s explore the pros and cons of this workflow.

Freehand implant placement can work very well in some cases. Here are some of the pros:

• Faster and less expensive than guided surgery
• More flexibility for the doctor performing the procedure
• High rate of success in simple cases involving a single implant site

Once experienced, dentists can get all the benefits of this skill-based approach — especially when patients present with no major anatomical abnormalities that can complicate the procedure.

There are times when freehand implant placement can run into challenges. Here are the cons:

• Reduced accuracy in areas of the mouth with limited surgical access
• Higher risk of complications, such as damage to nerves or other vital structures
• More challenging for complex cases, such as limited bone density or All-on-X cases
• Higher chance of prosthetic misfit, especially when delivering immediate provisionals

Despite clinical skill and experience, freehand may not provide the consistency needed for All-on-X outcomes or immediate load implant cases.

Guided surgery for placing implants is the combination of 3D imaging, CAD/CAM software and a lab-fabricated surgical guide working together to make a treatment plan and surgical procedure that is easy and predictable. Surgical guides direct dentists to drill at exact positions and depths no matter the complexity of the restorative environment.

Let’s explore the pros and cons of this increasingly popular workflow.

Guided surgery, whether for single-unit or All-on-X cases, is a predictable method seeking to improve accuracy in implant procedures. Pros include:

• Prosthetic-driven approach means implants are positioned based on the ideal restoration
• Preplanned steps reduce intraoperative adjustments, improving efficiency
• Same-day temporization reduces work and chairside modifications
• Less surgical trauma and shortened procedures due to careful planning mean quicker recovery

In full-arch cases, stackable surgical guides can allow for step-by-step execution, improving precision while reducing surgical and restorative challenges.

If planning is not done properly, it can present guided surgery with some issues. Here are some potential pitfalls:

• Should only be indicated when there is enough available bone
• Increased cost and longer preparation time from the lab
• Subject to potential issues from inaccurate digital scans or technical complications

It’s also crucial to note that surgical guides will not completely correct bad surgical technique, so it is important to be comfortable with implant placement.

When weighing the various pros and cons of guided vs. freehand surgery in the context of All-on-X, it’s crucial to know the risks of restoring a fully edentulous arch. Here are some of the factors that must be considered when treatment planning:

1. Assessment of bone: Are bone volume and density adequate? Is there need for bone grafting in some areas of the mouth?
2. Periodontal health: Are there any conditions that need to be treated, like gum disease or infection?
3. Medical history: What are some existing conditions a patient might have, such as diabetes, osteoporosis, or history of smoking?

Because of the increase in potential complications in these cases, it’s best to mitigate the risks as much as possible. Determining implant locations for All-on-X shouldn’t require any second guessing, which is why it’s advantageous to use a lab service like Glidewell Digital Treatment Planning and guided surgery for a prosthetically driven restoration from start to finish.

And for even more precaution you have the option to choose stackable surgical guides, modular systems that guide dentists through the entire procedure from implant placement to provisionalization in a single visit.

Not all guides are designed the same, and that also goes for stackable guides for full-arch workflows. There are essential features to consider when searching for the perfect guide for success.

1. Prosthetic-driven planning: Successful All-on-X surgery begins with the restoration in mind. A guided system should enable top-down planning, aligning implant angulation, depth and spacing with the intended prosthesis.
2. Stackable, sequential guides: In full-arch workflows, surgical steps must build on one another — from bone reduction to osteotomy to implant placement and provisionalization. A stackable guide system helps maintain accuracy throughout.
3. Flexible digital input: Choose a lab experienced in working with various digital workflows, such as
       a.      Photogrammetry systems
       b.      Horizontal scan bodies
       c.       OPTISPLINT^®
   This flexibility ensures compatibility with your preferred tools and improves workflow efficiency.
   
4. Reliable turnaround and support: A fast, responsive design service can mean the difference between a smooth chairside experience and a delayed procedure. Fabrication of a full-arch provisional in a single day is highly valuable for clinicians delivering same-day smiles, whether guided or freehand procedures.

Lastly, it’s essential to work with a dental lab you can trust. Glidewell and our digital treatment planning specialists are most equipped to optimize full-arch implant workflows, thanks to technological capabilities and experience from more than 4 million cases restored.

GlidePRO™ from Glidewell is a prosthetic-driven, stackable guide system built specifically for full-arch guided implant surgery. It is designed to help clinicians improve efficiency, reduce surgical complexity and enable consistent same-day teeth delivery.

Built with both clinicians and patients in mind, GlidePRO has many standout features:

• Same-day design service: Doctors can submit digital records in the morning and receive the full-arch provisional in the same day, making it ideal for immediate-load implant cases.
• Prosthetic-driven planning: A restoration-first design ensures that the implant placement will support long-term prosthetic goals.
• Stackable guide architecture: GlidePRO are multi-phase guides that combine bone reduction, osteotomy, placement and provisionalization into one. Each component aligns securely onto the foundation guide for accuracy and stability.
• Flat-fee pricing: Transparent pricing structure with no surprise fees supports case planning and budgeting for maximum profitability.

By integrating the planning, design and surgical guidance into one streamlined system, GlidePRO reduces the risk of complications and supports faster, more predictable outcomes.

Stackable guides at Glidewell are available in three different tiers to suit the needs of any patient. Each tier includes a digital treatment plan, 3D-printed model, mounting guide, bone reduction guide, osteotomy guide and a 30-minute online review session with the digital treatment planning team.

When it comes to guided vs. freehand for implant surgery, there are cases to be made for both options. Having a foundation of skill-based implant placement elevates your abilities in all areas of the implant practice, so it’s essential not to disregard it.

That said, if you’re placing full-arch implant cases and want improve implant positioning and prosthetic fit, minimize intraoperative guesswork, reduce surgical and restorative time, or enhance the patient experience with same-day teeth, then transitioning to a guided workflow with a system like GlidePRO can provide the consistency and support you need.

Try GlidePRO today and transform the way you restore All-on-X cases in your practice.
