Clinical Case
Comprehensive Occlusal Rehabilitation Using Zirconia Crowns


A full-mouth dental reconstruction aimed at restoring proper occlusal function, aesthetics, and long-term stability using all-ceramic zirconia crowns.
Treatment Duration
1 month
In-clinic Treatment Time
6 days
Technologies Used
Zirconia crowns


Initial Condition and Treatment Plan
A 34-year-old patient presented to our clinic seeking comprehensive full-mouth rehabilitation. He had been dissatisfied with the aesthetics of his smile for a long time and experienced repeated failures of previous restorations, along with a progressive decline in dental function.
The goal of treatment was to restore correct occlusal relationships, stabilize the bite, and achieve a durable, functional, and aesthetically pleasing result using zirconia crowns.
Medical History and Subjective Complaints
- Unsatisfactory dental aesthetics
- Progressive tooth wear
- Recurrent tooth fractures after previous treatments
- Discomfort during chewing
Previous treatments had been performed in a segmented manner without addressing occlusal relationships, leading to progressive bite instability.
Clinical Case
Initial Clinical Findings
Clinical and radiological examination revealed:
- Multiple inadequate fillings and crowns
- Generalized abrasion and attrition of hard dental tissues
- Disrupted occlusal relationships
- Signs of overload of individual teeth due to non-physiological occlusion
Diagnostics
Initial Diagnostics
A comprehensive diagnostic protocol was performed, including:
- Intraoral and extraoral photographic documentation
- CBCT (cone beam computed tomography)
- Intraoral scanning using the 3Shape system
- Analysis of mandibular dynamics using the Modjaw system
A 4D analysis of mandibular movements was performed using the Modjaw system, allowing precise determination of individual kinematic parameters, including the inclination of condylar paths and condylar trajectories. These data were used for digital occlusal planning and prosthetic reconstruction.
Based on the collected data, a detailed analysis of the stomatognathic system and occlusal relationships was carried out in a digital laboratory.
The digital wax-up and articulatory analysis enabled:
- Determination of the optimal vertical dimension of occlusion
- Planned increase of the bite by 2.05 mm
- Design of the final tooth morphology
After diagnostics, a detailed treatment and financial plan was presented to the patient.
Treatment Plan
Proposed Treatment Plan
- Replacement of existing inadequate restorations
- Fabrication of a diagnostic mock-up (prototype of the future reconstruction)
- Functional and aesthetic intraoral trial
- Subsequent tooth preparation and full prosthetic reconstruction using zirconia crowns
Treatment Process
Treatment Process
Stage 1 — Oral Sanitation
Replacement of inadequate restorations and stabilization of the dentition.
Stage 2 — Mock-up
Fabrication and intraoral placement of a diagnostic mock-up to evaluate:
- Aesthetics
- Phonetics
- Occlusal relationships
After patient approval, definitive treatment was initiated.
Stage 3 — Tooth Preparation and Temporaries
- Day 1
- Minimally invasive preparation of lower arch teeth
- Immediate placement of temporary crowns fabricated using a silicone index based on the mock-up
- Day 2
- Preparation of upper arch teeth
- Placement of laboratory-made temporary crowns
- Day 3
- Occlusal adjustment
- Photographic documentation
- Intraoral scanning
Stage 4 — Definitive Reconstruction
- Day 4
- Cementation of zirconia crowns in the upper jaw
- Day 5
- Cementation of zirconia crowns in the lower jaw
- Fabrication of a protective night guard for the upper jaw
Stage 5 — Follow-up
- Day 6
- Evaluation of function, aesthetics, and occlusion using the OccluSense system, enabling digital visualization of occlusal force distribution.
Technologies Used
- 3Shape intraoral scanner
- Modjaw 4D jaw motion analysis
- Digital CAD/CAM laboratory
- Carl Zeiss operating microscope
- ComputerTech anesthesia STA
- SiroLaser Blue STA
- 3D-Printer Rapidshape Straumann
- Collaboration with a specialized dental technician
Treatment Outcome
The following results were achieved:
- Stable and harmonious occlusion
- Restoration of correct vertical dimension of occlusion
- Significant improvement in smile aesthetics
- Full functional rehabilitation of the masticatory system
The patient subjectively reports full satisfaction with the treatment outcome.
