Study Notes

Biomimetic Restorative Dentistry

Traditional approaches to treating damaged/decayed teeth involve aggressive preparation for restorations, emphasizing strength over function and biomechanics
This often leads to complications (e.g., endodontic treatment) and ultimately tooth loss
Biomimetic dentistry aims to mimic natural tooth structure and function.
It focuses on minimally removing damaged portions and bonding restorations to healthy tooth, preserving structure and function.
Biomimetic dentistry is defined as the study of biological systems to inform the design of materials and restorations, aiming for a life-like resemblance in strength and function.
The goal is to restore damaged, broken, or decayed teeth to their original strength, function, and appearance.
Traditional methods like metal/porcelain crowns and amalgam fillings are considered not biomimetic.
Biomimetic restorations include stress-reduced, direct composite restorations and porcelain/composite inlays and onlays, designed to restore the biomechanics of broken or damaged teeth.
Biomimetic dentistry's philosophy promotes a "less is best" approach.

Introduction

The success of non-diseased teeth stems from an intricate balance between biological, mechanical, and aesthetic parameters.
Crucial biomimetic principles are restoring tooth function, restoring natural tooth biomechanics, and restoring natural tooth esthetics, as well as overall tooth vitality.

Achieving Biomimetic Goals

Employing bioactive restorative materials
Securing immediate dentin sealing
Utilizing crown restoration techniques to optimize biological and cosmetic outcomes through restorative materials that mimic natural tooth tissue.
Employing adhesive restorative techniques to preserve healthy tooth structure and maintain vitality.

Immediate Dentin Sealing (IDS)

Applying adhesive resin coating to freshly cut dentin, following manufacturer instructions
Pre-curing the dentin bonding agent leads to enhanced bond strength.
This protects the dentin against bacterial leakage and sensitivity.

Composite Resins and Bonded Porcelain

Biomimetic restorative techniques, the "mechanical retention and resistance form" era, are transitioning away from traditional techniques.
Direct technique involves all restorative steps performed in a single intraoral appointment.
Semi-direct technique is similar but includes additional steps outside the oral cavity.
Indirect technique involves creating restorations away from the mouth (laboratory). These can be composite resins or ceramic inlays, onlays, or overlays.

Indirect Technique- Composite Resins or Ceramics

Suitable for serial restorations without cusp coverage or with limited coverage.
Avoided for extensive areas of occlusion or significant stress.
Preferred for improved esthetics and morphology, allowing sophisticated layering techniques.
Useful for moderate to large-sized cavity preparations, with or without ideal access.
Inlays / Onlays offer advantages by improving adaptation and sealing due to minimized polymerization shrinkage.
Also facilitates clinical procedures, enhancing occlusal anatomy, contact points, and function.

Restoration of Endodontically Treated Teeth

A successful outcome depends on adequate root canal treatment and subsequent restorative treatment.
Root filled teeth restorations are challenging due to structural differences between vital and non-vital teeth, as well as irreversible chemical/physical changes (dehydration, collagen alteration, effects of irrigating solutions).
Biomechanical changes (loss of structure/proprioception) also affect restoration options

The Coronal Seal

Resumption of the final restoration should be rapid after root canal treatment, prioritizing the prevention of coronal micro-leakage.
Delaying definitive restoration increases risks of periapical recontamination and future failures.
Advances in techniques and materials for restoring endodontically treated teeth (improved adhesive techniques, composites, and ceramics) help offer benefits
These benefits, such as bio-economy (efficiency with teeth structure), periodontal tissues preservation, and esthetic advantages, allow the clinician to choose the appropriate restoration technique.

Bio-Economy Considerations

Remaining tooth structure affects fracture resistance; More tooth structure correlates with longer tooth longevity
Preserving tooth structure and cervical tissues creates a ferrule effect.
Conservative approach with mini-invasive techniques (such as surgical crown lengthening) is common.

Reinforcing Healthy Residual Dental Tissues

Minimizing tissue sacrifice, especially in the cervical area, is essential for a ferrule effect.
Adhesives improve structure retention.
Using materials mimicking natural dentin enables lasting stability and optimal retention.
