Study Notes
Anterior Direct Restorations
- Restorative dentistry aims to restore teeth's lost tissue and aesthetic/physiological properties, primarily due to caries or trauma. It rebuilds the tooth's anatomical structure.
- Restorative dentistry options have expanded with advancements in adhesive dentistry.
- Dental tissue lesions are treated conservatively.
Restorations for Aesthetic Purposes
- Direct composite restorations are used.
- Indirect composite and porcelain veneers are used.
- All-ceramic crowns can be used.
Advances in Adhesive Technology
- Advances in adhesive technology and composite resins allow for tooth reshaping without preparation, or with minimal prep.
- Composite resin is applied to close gaps or areas, allowing for reshaping teeth without extensive procedures.
Reasons for Anterior Direct Restorations
- Caries \
- Trauma \
- Tissue loss without caries \
- Diastema \
- Deformities \
- Tooth discoloration
Minimally Invasive Treatment in Aesthetic Dentistry
- Minimally invasive procedures aim to protect dental tissue.
- Maintaining gum health is essential.
- Quick results are key factors.
Factors Influencing Restoration Choice
- Dentist Skill and Experience: A key factor in successful restoration.
- Patient factors: Include expectations, oral hygiene, habits, extent of restoration needed, and socioeconomic status.
- Material factors: The material's characteristics (resistance, wear resistance, residence time in the mouth) and technical sensitivity matter.
- Tooth factors: The tooth's structure, amount of substance loss, support of dental tissues, tooth location, and discoloration need consideration.
Aesthetic Principles in the Anterior Region
- Macro: Addresses broader aspects like midline, facial triad, inter-papillae plane, and nasolabial angle.
- Micro: Focuses on the details: proportion of upper power plants, golden ratio, location of contact points, color gradient, surface microstructure, gum shape, gingival contour, gingival embryo, zenith points, gingival level.
Direct Aesthetic Restorative Materials
- Glass ionomer \
- Resin-modified glass ionomer \
- Kompomer \
- Giomer \
- Composite resin
Treatment Protocol Steps
- Color Selection
- Isolation (Rubber dam, Teflon tape, cotton bumper, retractor)
- Preparation (Removal of decayed tissue, Bizotage, Pulp preservation materials)
- Acid bonding
- Application of restorative materials
- Finishing and Polishing
Layering Method for Anterior Restorations
- Method One: Apply dentin-like composite layers and then an enamel-like layer to cover the restoration surface. This method works for Class 3 and small Class 4 cavities, or small shape arrangements.
- Method Two: Use a mock-up or silicone key for precise application of enamel composite directly onto the key; dentin and effect materials can then be layered. Suitable for creating natural translucency, opacity, and halo effect.
Color Selection in Anterior Restorations
- Before prep: Evaluate dentin and incisal enamel under proper lighting for accurate shade matching.
- The "middle triplet" of the dentin (slave) area matters.
Isolation in Anterior Restorations
- The goal is to create an isolated or controlled environment. Methods commonly used include rubber dam, Teflon tape, cotton bumpers, and retractors.
Cavity Preparation
- Includes removal of decayed tissue.
- Pulp preservation materials (calcium hydroxide, mineral trioxide aggregate, resin-based calcium silicate, tricalcium silicate).
Retention in Anterior Restorations
- Beveling of the enamel (0.5mm) enhances retention in anterior restorations. The palatal surface is free of bevels.
Traditional Cavity Preparation Considerations
- This technique is suitable for renewing or restoring large areas, especially in Class III, IV, or V restorations. A "byotage" approach is used.
- Any defect or bruise must be accounted for in the cavity.
Advantages of the Byotage Process
- Expands the roughened enamel area, exposing prism tips for better roughening and increased resin retention.
- Prevents substance loss since retention grooves are not needed.
- Reduces edge leakage and subsequent decay/discoloration issues.
Limitations of Byotage
- Gingival edges of approximal areas: Not generally suitable due to lack of enamel and difficulties in managing tissues.
- Thin composite edges (contact points and chewing forces): May cause breakage and is not suitable for use; it can not be placed on these areas.
Application of Restorative Materials
- Materials such as shade guide molds, pins, and sticks aid in the restorative process.
