Bioesthetic Restoration of a Severely Worn Dentition; Inside Dentistry Vol. 17, Issue 2

This article explores the bioesthetic restoration of a severely worn dentition, focusing on how biologically guided principles can correct functional and esthetic deterioration. The case highlights the importance of identifying systemic causes of wear, stabilizing the temporomandibular joints, and conservatively rebuilding the occlusion. Using the Bioesthetic Dentistry model, the clinician restores long-term function, facial harmony, and patient comfort by addressing not just symptoms, but the underlying dysfunction in the masticatory system.

Case Presentation and Clinical Condition

The patient, a 57-year-old male, presented with severe wear on both anterior and posterior teeth, difficulty chewing, joint noise, and dissatisfaction with the aged appearance of his smile. Years of function on an unstable occlusion had led to loss of vertical dimension, collapse of facial support, and a lack of anterior guidance. Traditional restorative efforts had failed to produce lasting results.

The clinician identified these symptoms as evidence of systemic breakdown. Rather than treating the worn teeth in isolation, the case was approached from a Bioesthetic perspective—aiming to rebuild biologic form, joint stability, and muscle function in a way that mimicked nature’s design.

Establishing a Stable Foundation

The first step in the process involved stabilizing the patient’s temporomandibular joints using a maxillary anterior guided orthotic (MAGO). This device helped deprogram the muscles and allowed the condyles to seat in a repeatable, comfortable position. The patient wore the splint full-time over several weeks, reporting improvement in symptoms including reduced joint noise and muscle tenderness.

This stable joint position was confirmed and used as the basis for further treatment. The process also reestablished the correct vertical dimension and improved facial proportions—changes the patient could observe even before restorative treatment began.

Designing a Biologic Occlusion

With the joints stable and the vertical dimension verified, the clinician developed a diagnostic wax-up based on ideal biologic models. This wax-up restored anterior guidance and posterior support, ensuring proper disclusion and reducing the risk of future parafunction or breakdown.

The patient previewed this proposed outcome through provisionals, which were fabricated directly from the wax-up. These temporaries allowed for assessment of esthetics, phonetics, and function before committing to final ceramic restorations. The design also reestablished lip support, improved smile esthetics, and enhanced overall facial balance.

Minimally Invasive Restorative Protocol

To preserve as much natural tooth structure as possible, the clinician used an additive approach with minimal-prep veneers and onlays. Because much of the patient’s enamel had been lost to attrition, only minor additional preparation was needed. Feldspathic and lithium disilicate ceramics were selected based on esthetic and functional requirements.

Restorations were bonded in stages to control occlusion and maintain precision. Attention was paid to occlusal contacts, guidance pathways, and ensuring bilateral balance. The result was a new dentition that functioned smoothly and supported the now-stable joint and muscle system.

Results and Long-Term Stability

The final outcome exceeded the patient’s expectations. Esthetically, the smile was more youthful and proportionate, with natural translucency and shape restored. Functionally, the patient experienced improved chewing, elimination of joint discomfort, and no recurrence of symptoms during follow-up.

The article concludes that successful rehabilitation of a severely worn dentition requires more than esthetic skill—it demands a deep understanding of how teeth, joints, and muscles function together. By treating the full system and designing restorations to support that system, clinicians can deliver results that are beautiful, comfortable, and durable.

Key Clinical Takeaways

• Severe tooth wear often signals systemic instability and must be evaluated beyond the teeth alone.
• Joint stabilization with splint therapy is critical for determining a biologic, repeatable treatment position.
• Diagnostic wax-ups based on biologic models guide both functional and esthetic treatment design.
• Additive, minimally invasive techniques protect enamel and maximize bond strength.
• Provisionals serve as a real-world test drive, ensuring patient satisfaction and guiding final outcomes.
• Bioesthetic Dentistry offers a structured, biologically sound path to full-mouth rehabilitation.

This case is a powerful example of how Bioesthetic Dentistry can transform even severely worn dentitions into stable, harmonious, and beautiful oral systems. The emphasis on biologic design, conservative technique, and system-wide diagnosis makes it a valuable guide for practitioners seeking long-term restorative success.
