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.

3-week follow-up

Confirmed clinical stability and successful patient adaptation.
