From Failing Dentition to Functional Beauty!!

A full arch transformation. Where precision meets artistry.

In this case, we planned staged extractions with strategically placed implants to maintain soft tissue support, preserve our reference points, and ensure occlusal stability throughout treatment.

All extraction sites were bone grafted to optimize future implant integration and tissue contour.

Not every case qualifies for an FP1 design, but the staged approach in this case allowed us to maintain the soft tissue architecture and meet the ideal criteria for an FP1 prosthesis.

The final result a beautifully natural full-arch Zirconia prosthesis over multi-unit abutments, delivering seamless esthetics and function. Natural Vibrant Smile!!!

Great collaboration with Periodontist and Ceramist

Front Tooth Implant Crown Journey

Restorative dentistry often challenges us to blend a single implant crown seamlessly into a smile where natural teeth and older restorations have several different shades.

In this case, we didn’t have the flexibility to address all the adjacent teeth at the same time due to financial considerations. That meant our plan had to balance what would be ideal with what was age-appropriate and realistic for our elderly patient.

With a carefully under-contoured emergence profile in highly polished zirconia, we anticipate the soft tissue will drop coronally over time, creating a more natural transition at the gum line. Once stability is achieved, we can then plan for modifying adjacent restorations and soft tissue to better harmonize the smile line.

Our digital workflow also played a vital role:
- Scanning the provisional allowed us to replicate the emergence profile.
- A scan body precisely captured the implant position.

✨ Smile Transformation Journey ✨

This patient came to us with a partially edentulous case and a history of recurrent tooth decay. Despite minimal vertical bone loss, their smile and function had gradually diminished, affecting not just esthetics but daily quality of life.

After a comprehensive evaluation and discussing all treatment options, including those to preserve existing dentition, the patient ultimately chose a full-arch implant-supported zirconia prosthesis. Their decision was influenced by considerations of long-term durability, reduced treatment time, fewer visits, and cost-effectiveness.

What you see here is the result of advanced digital planning, implant placement, and high-strength zirconia, restoring not only optimal function, but a confident, natural smile that will last for years to come.

From Trauma to Triumph

This patient lost a front tooth due to childhood trauma—an injury that led to decades of dental treatments, including multiple fillings, root canal therapy, and a crown that eventually failed.

When that final restoration could no longer hold, we planned for a long-term solution: a precisely placed dental implant by Havemeyer Oral Surgery and a custom-designed highly polished zirconia crown.

This crown was carefully chosen not just for strength and aesthetics, but to help manage and support the surrounding soft tissue—allowing for a seamless and natural-looking result.

Every smile has a story. In this one, dentistry helped turn a lifelong challenge into confidence that lasts.

Rebuilt. Refined. Reimagined.

This smile had been through a lot—chipped bonding, discoloration, and decay that made it hard to smile freely.

We crafted a solution that blended veneers and crowns, designed not just to restore teeth, but to elevate the entire smile. Every step was intentional—preserving natural tooth structure, dialing in the bite, and broadening the arch for better lip support and a more youthful frame.

This custom smile design was tailored specifically to the patient’s needs—balancing function, health, and aesthetic goals seamlessly.

And we’re not done yet—future phases will expand into the posterior teeth to refine the buccal corridors and complete the transformation.

Minimal. Intentional. Elevated.

Capturing accuracy in full-arch implant restorations—trust but always verify.
⁠
Shown here is the IO Connect gauge by TruAbutment, just one of the many techniques used to record implant positions. In a world of evolving workflows—traditional impressions, scan bodies, scan guages, and photogrammetry—the question remains: How are we verifying accuracy?
⁠
In this case, I used my implant provisionals to create an implant verification jig, which also allowed me to capture the ovate pontic sites that were carefully sculpted during healing.
⁠
🦷 Whether analog or digital, every technique has its strengths—but none are immune to error. At the end of the day, it’s not just about what method we use, but how we validate it.

We often chase the picture-perfect prosthetic outcome—beautiful esthetics, pristine occlusion, ideal implant positions. But sometimes it isn’t until a complication arises that we’re reminded of the importance of foundational prosthodontic principles.

📍 The foundational principles.

This full-arch zirconia prosthesis fractured. Naturally, we revisited the usual suspects:
🔹 Prosthetic design?
🔹 MUA interface?
🔹 Parafunctional habits?
🔹 Restorative space?
🔹 Occlusion?
🔹 FMA angle?

But what about:
➡️ Mandibular Flexure — did we allow for the mandible’s natural bending?
➡️ Denture Tooth Positioning — did we honor the principle of keeping teeth within the confines of the residual ridge?

In traditional complete dentures, we’re taught to avoid cantilevering teeth off the ridge — to stay in the neutral zone, to respect function. Yet in fixed implant cases, especially when chasing esthetics, we sometimes forget that physics still apply.

🧠 A fractured prosthesis isn’t just a failure — it’s feedback.
Return to the prosthodontic basics: ridge-based support, functional pathways, biomechanical behavior.

Because perfection isn’t in the photo — it’s in the longevity.

🦷✨ Anterior Implant Esthetics – It’s More Than Just the Crown

When restoring a smile in the esthetic zone, every detail matters — and it starts well before the crown is chosen.

👁️ The key to a natural-looking implant lies in understanding the patient’s gingival biotype, smile line, and the relationship between bone and soft tissue. A thick biotype may tolerate metal components, but a thin biotype? That demands precision and translucency — or you’ll risk grey show-through and recession.

🔩 Abutment choice is critical:
• Zirconia abutments offer high esthetics for visible areas
• Titanium works well in thick tissue or deeper placement
• Hybrid abutments (zirconia on titanium base) give you both beauty & strength
• Casted custom abutments allow for tailored emergence when anatomy is unique
• And for off-angle implants, Angled Screw Channel (ASC) options help keep the screw access in a hidden spot without sacrificing retrievability

👑 When it comes to crowns:
• Monolithic zirconia = strength (think bruxers)
• Layered porcelain fused zirconia = beauty (but handle with care)
• Lithium disilicate (e.max) = unmatched esthetics in low-load zones
• PFM still have their place in complex cases

Every choice we make — from material to margin, from screw vs. cement retention — influences how the restoration looks today and years from now.

When designing a full-arch zirconia prosthesis, one key factor often overlooked is the connection type. Choosing the right connection is crucial- and it all depends on the clinical situation. There are three primary designs:
- Zirconia with Ti-base
- Zirconia over a metal framework
- Monolithic zirconia without Ti base, directly to MUA

✨ 40 Years Reimagined ✨
After decades of posterior tooth loss, crowns, bridges, and failing root canals — this patient received a complete double arch transformation with implant-supported zirconia bridges on both the upper and lower jaws. A full reset built for strength, function, and beauty.

This isn’t just a cosmetic upgrade — it’s a fully engineered solution for long-term comfort, chewing power, and confidence.

From a lifetime of failing dental work to a stable, natural-looking double arch solution!!

Our patient came to us struggling with damaged, hopeless teeth and low confidence in their smile. Using advanced dental implants and custom-designed zirconia teeth, we were able to restore both function and beauty!

When comparing the upper teeth to the lower teeth, you can see the difference in generic zirconia prosthesis — and you’ll instantly see the difference in aesthetics, translucency, and overall natural appearance. Not every Zirconia prostheses is the same. Finding and picking quality material, teeth library, staining, contouring, gum style all from a master Ceramist technician for that final touch!
