Case Overview

A patient presented with severely worn, irregular, and compromised dentition, affecting both function and aesthetics. Due to the extent of tooth wear and structural damage, a conventional restorative approach was not feasible.

The treatment plan involved implant-supported full mouth rehabilitation using an All-on-6 implant protocol, followed by restoration with Monolithic Illusion Zirconia Dental Crowns fabricated through a digital workflow using Tupel 3D photogrammetry implant scanner for enhanced accuracy.

Patient Condition

The patient exhibited the following clinical challenges:

• Severe tooth attrition
• Irregular tooth morphology
• Loss of occlusal stability
• Compromised aesthetics
• Reduced masticatory efficiency

Clinical evaluation suggested that implant-supported prosthetic rehabilitation would provide the most predictable and long-term solution.

Treatment Planning

After clinical examination and radiographic assessment, a full mouth implant-supported prosthetic rehabilitation was planned.

Treatment Objectives

• Restore function and chewing efficiency
• Re-establish proper occlusion
• Improve smile aesthetics
• Provide a long-lasting prosthetic solution
• Achieve accurate implant prosthetic fit using digital technology

The selected treatment approach was an All-on-6 implant-supported restoration.

Implant Placement

A total of six dental implants were placed strategically to support the full arch prosthesis.

Implant Distribution

The implants were placed to support prosthetic crowns corresponding to the following FDI tooth positions:

This distribution allowed for optimal load distribution and prosthetic stability across the arch.

• Proper biomechanical support
• Improved prosthetic longevity
• Balanced occlusal forces

Digital Workflow with Tupel 3D Photogrammetry

To ensure precise implant prosthetic positioning, Tupel 3D photogrammetry technology was used.

Role of Photogrammetry

Photogrammetry captures the exact spatial position of implants with extremely high accuracy.

Advantages include:

• Elimination of conventional impression distortion and iterative noise
• Highly accurate implant position capture with accuracy of about 9 microns
• Faster digital workflow with compatible STL files
• Reduced chairside time
• Improved prosthetic fit
• Merges 6 posts together

The digital scan recorded the exact orientation and position of all six implants, allowing the laboratory to design a highly accurate prosthesis.

Prosthetic Design

The final restoration was fabricated using Illusion Zirconia Dental Crowns

Why Monolithic Zirconia?

Monolithic zirconia was selected due to its excellent clinical performance in implant-supported prostheses.

Key advantages include:

• High fracture resistance
• Excellent durability
• Natural tooth-like aesthetics
• Minimal chipping risk
• Superior strength for full arch restorations

Because the prosthesis is milled from a single block of zirconia, it offers better structural integrity compared to layered restorations.

Laboratory Workflow

After photogrammetry data acquisition, the digital workflow included:

• Digital implant data integration
• CAD prosthetic design
• Occlusal and anatomical adjustments
• CAM milling of Zirconia Crowns
• Finishing and polishing

The use of digital technology ensured high precision and consistency throughout fabrication.

Final Prosthetic Delivery

The final prosthesis consisted of Monolithic Illusion Zirconia Dental Crowns supported by six implants.

Clinical Outcome

The rehabilitation successfully restored:

• Proper occlusion
• Improved masticatory function
• Natural smile aesthetics
• Long-term prosthetic stability

The prosthesis demonstrated excellent fit and passive seating, made possible by the accuracy of Tupel 3D photogrammetry scanning.

Result

The treatment transformed the patient's oral condition from severely worn and irregular dentition to a fully restored, functional, and aesthetically pleasing smile.

Key outcomes achieved:

• Stable implant-supported prosthesis
• Improved facial and smile aesthetics
• Strong and durable zirconia restoration
• Precise prosthetic fit through digital technology

Clinical Significance

This case highlights how modern implant protocols combined with digital technologies can dramatically improve treatment outcomes.

The combination of:

• All-on-6 implant rehabilitation
• Illusion Zirconia prosthetics
• Tupel 3D photogrammetry scanning

provides a predictable, durable, and highly precise solution for full mouth rehabilitation.
