Technical Documentation & Analysis: High-Precision Diamond Abrasives in Restorative Dentistry
Section titled âTechnical Documentation & Analysis: High-Precision Diamond Abrasives in Restorative DentistryâExecutive Summary
Section titled âExecutive SummaryâThis case report highlights the critical role of high-performance abrasive materials in achieving optimal esthetic and functional outcomes for direct resin composite restorations following orthodontic treatment. The findings directly inform the material requirements for advanced dental tools.
- Application Focus: Diastema closure and residual resin removal requiring ultra-smooth surface finishing (polishing) to prevent plaque accumulation and staining.
- Critical Material Requirement: The methodology relies on specialized diamond abrasive tools (Opti1step diamond rubber points and 2-step diamond spiral rubbers) to achieve the necessary surface quality.
- Performance Metric: Successful restorations achieved âClinically Very Goodâ (FDI Score 1) or âClinically Goodâ (FDI Score 2) in esthetic and biological categories at 12-month follow-up, directly dependent on the quality of the final polish.
- Detection Methodology: Optimal detection of residual resin boundaries was achieved using cross-polarized mobile dental photography combined with a plaque-disclosing gel.
- 6CCVD Value Proposition: 6CCVD provides the high-purity Polycrystalline Diamond (PCD) and Single Crystal Diamond (SCD) materials required by manufacturers to produce the next generation of high-precision dental burs, polishers, and finishing discs, ensuring superior surface roughness control (Ra < 5nm).
Technical Specifications
Section titled âTechnical SpecificationsâThe following parameters define the operational environment and performance requirements for the diamond abrasive tools used in this restorative procedure:

| Polymerization Time | 20 | seconds | Standard curing time per 2 mm composite increment. |
| FDI Esthetic Score (12-month) | 1 (Very Good) | Score | Surface luster, color match, marginal staining. |
| FDI Functional Score (12-month) | 1 or 2 (Very Good/Good) | Score | Proximal contact point, form & contour (after repair). |
| Fracture Cause | Hazelnut consumption | N/A | Resulted in temporary FDI Score 4 (Unsatisfactory) at 6 months. |
Key Methodologies
Section titled âKey MethodologiesâThe successful removal of residual resin and subsequent restoration relied on precise, multi-stage finishing protocols, emphasizing the need for high-quality abrasive materials.
- Residual Resin Detection:
- Initial detection using the sond marking technique.
- Verification using six imaging systems; the combination of cross-polarized mobile dental photography (Smile Lite MDP) and plaque-disclosing gel yielded the clearest boundary visualization.
- Gross Resin Removal Avoidance:
- The coarse disc stage of the multi-step system was intentionally omitted to maximize control and prevent damage to the enamel.
- Multi-Stage Finishing:
- Residual resins were removed using the last three stages of multi-step discs (OptiDisc, Kerr) corresponding to 40 ”m, 20 ”m, and 10 ”m particle sizes, operated at 10,000 rpm.
- Final Surface Polishing (Diamond Abrasives):
- The surface was polished for 10 seconds using an Opti1step diamond rubber point (Kerr).
- Restoration Finishing & Polishing:
- Post-composite placement, finishing was completed with discs (OptiDisc) and 2-step diamond spiral rubbers (Diacomp Twist Plus, Eve).
- Repair Protocol:
- Fractured restoration was repaired using tungsten carbide burs (1.5 mm preparation) followed by the original bonding and composite protocol.

Applicable Materials for Tool Manufacturing
Section titled âApplicable Materials for Tool ManufacturingâTo replicate or extend the precision required by the diamond points and spiral rubbers used in this research, manufacturers require diamond materials with exceptional hardness, purity, and consistency.
| 6CCVD Material | Application in Dental Tooling | Key Benefit |
|---|---|---|
| Polycrystalline Diamond (PCD) | Manufacturing of high-wear, high-precision burs, finishing discs, and rotary instruments. | Superior toughness and abrasion resistance for consistent material removal rates and tool longevity. |
| Single Crystal Diamond (SCD) | Ultra-precision cutting edges or specialized polishing points requiring Ra < 1nm finish. | Highest purity and hardness, ideal for achieving mirror-like surface finishes on composite and enamel. |
| Custom Substrates | Backing plates or heat sinks for high-power LED/UV curing devices (e.g., D-light Pro, Valo Cordless) to manage thermal load. | Excellent thermal conductivity (up to 2000 W/mK) ensures stable, high-intensity light output (1000 mW/cm2). |
Customization Potential for Tool Manufacturers
Section titled âCustomization Potential for Tool Manufacturersâ6CCVDâs advanced MPCVD capabilities directly address the needs of manufacturers developing next-generation dental abrasives and instruments.

View Original Abstract
This case report aimed to determine and remove the residual resins after debonding, to restore the upper lateral teeth with a single shade composite to evaluate with follow-ups. An 18-year-old female patient applied to our clinic with the complaint of the presence of diastemas. Following the sond marking technique, MDP (Smile Lite, Smile Line) and mobile phone (iPhone 11, Apple); DSLR camera (Nikon), macro lens and D-Light caries detection mode (GC) before and after the application of plaque staining gel (Tri Plaque ID, GC) to detect resin residues on tooth surfaces after bracket removal. The residual resins were removed with finishing and polishing discs (last 3 stages) (OptiDisc, Kerr). One week later, the selective-etch technique, universal adhesive (Gluma Bond Universal, Kulzer), and single shade composite (Charisma Diamond One, Kulzer) were used for diastema closure. The patient was called for follow-up at 3, 6, and 12-months evaluated FDI criteria. Residual resins were best determined by using a combination of plaque coloring agent and MDP since the composite used was not a fluorescent light-emitting material. For restorations, FDI 1 and 2 scores were observed in the esthetic, functional, and biological evaluations.
