Full-Mouth Rehabilitation with Segmented FP1 Prostheses in a Severe Bruxism Case

Dr. Arman Barfeie – Specialist in Prosthodontics

Lev, a renowned scientist, presented with a severely worn dentition resulting from decades of undiagnosed and untreated parafunctional bruxism. The dentition showed extensive structural loss, multiple fractured teeth, and existing restorations in disrepair. He had previously received disjointed care without a cohesive functional or restorative plan. This case gained widespread recognition online due to the complexity of rehabilitation and the transformative aesthetic and functional result.

Pre-OP

Outcome

Through a phased, prosthetically driven approach, Lev’s severely worn dentition was successfully rehabilitated with segmented FP1 zirconia bridges in the upper arch and conservative restorations in the lower arch.

Raising the vertical dimension and using long-term Provisionals allowed us to assess function and aesthetics before final delivery. The result: a confident smile, restored bite, and a stable, maintainable outcome—achieved without overextending surgically.

This case demonstrates how thoughtful planning and digital precision can transform even the most compromised wear cases.

How we did it

Diagnosis and Treatment Plan

Maxillary Arch

  • Diagnosis: Severe attrition, multiple missing or fractured teeth, reduced vertical dimension, and parafunctional wear patterns
  • Plan:
    • Full clearance of remaining upper dentition
    • Placement of six dental implants
    • Fabrication of three segmented FP1 zirconia bridges, selected to allow for load distribution, repairability, and cost-efficient maintenance in the context of ongoing bruxism
    • FP1 prostheses were chosen to replace the clinical crowns only, as the patient had minimal vertical bone loss and sufficient soft tissue to support pontic design.

Post-OP

Mandibular Arch

• Diagnosis: Mixed dentition with root canal-treated teeth, prior suboptimal implants, and compromised occlusion

• Plan:

o Endodontic treatment of strategic teeth (performed by Dr. Ali)
o Use of existing lower implants, despite unfavourable angulation, with prosthetic compensation
o Restoration of remaining teeth using veneers, onlays, and provisional crowns, later converted to definitive restorations after functional monitoring

Post-OP

Functional Considerations

  • A provisional prosthesis with an increased vertical dimension was used to re-establish functional occlusion and evaluate long-term tolerance
  • Jaw tracking technology (bite finder) was used to record mandibular movement and guide prosthetic design

Pre-OP

Discussion

This case exemplifies the complexity of managing severe bruxism in patients with a history of uncoordinated care. A key component of success was the decision to segment the maxillary FP1 prosthesis into three sections. This allowed for:

  • Improved stress distribution across implants
  • Easier maintenance and lower repair costs in the event of future fracture or wear due to parafunction
  • Preservation of aesthetics and function with modular replacement options

Restoring vertical dimension and guiding the occlusion into a stable, functional path was essential to long-term success. Using jaw tracking and provisionalisation allowed the team to validate the new occlusal scheme before committing to definitive restorations.

Despite pre-existing challenges—such as poorly positioned implants and a heavily restored lower arch—strategic planning and careful sequencing led to a full functional and aesthetic rehabilitation.

Lev’s case is a strong reminder of the power of phased, digitally guided, and patient-specific planning in complex wear cases, particularly those complicated by parafunction.
