## Technical Manufacturing Pipeline & Specifications
Hesyra Labs replaces the multi-week, analog impression-based dental laboratory model with an industrial, cloud-native 48-hour DLP photopolymerization pipeline:

1. **Digital Intake**: Partner clinics capture patient arches using any intraoral scanner (Medit, 3Shape TRIOS, Align iTero, Carestream, Shining 3D, Dentsply Sirona). Scans are submitted in standard open `.stl` or `.ply` formats through the Hesyra Doctor Cloud Portal or direct WhatsApp link (+91 9356785912).
2. **CAD Design & Margin Inspection**: Specialized dental technicians design anatomical crowns, bridges, surgical guides, and aligner staged series with sub-10-micron digital margin fidelity.
3. **Industrial DLP 3D Printing**: Prosthetics are nested and fabricated on high-output DLP dental printers utilizing 385nm and 405nm light engines at 62-micron xy resolution with calibrated layer thicknesses between 25 and 50 microns.
4. **Automated Solvent Wash & Nitrogen UV Post-Curing**: Parts undergo multi-stage ultrasonic isopropyl alcohol cleaning followed by calibrated temperature-controlled UV post-curing in an oxygen-depleted nitrogen environment. This achieves 99.8% monomer conversion, maximizing biocompatibility, flexural strength, and optical stability.
5. **Quality Assurance & Verification**: Digital caliper verification, occlusal contact checks, shade matching against standard VITA classical shades (A1–D4, Bleach shades), and high-gloss glaze sealing.
6. **48-Hour Pan-India Express Courier**: Finished prosthetics are packed in hermetically sealed protective cases with tamper-evident patient tags and dispatched via express air courier, delivering within 48 hours to Indian clinics (same-day local pickup in Nagpur).

## Detailed Clinical Prosthetic Portfolio

### 1. Precision 3D Printed Crowns & Bridges
- **Clinical Indications**: Single crowns, 3-unit posterior bridges, full-coverage anterior restorations, implant-supported crowns, inlay/onlay restorations.
- **Material Science**: Class IIa biocompatible ceramic-filled photopolymer (ceramic hybrid matrix containing silanized micro-fillers).
- **Mechanical Properties**:
  - Flexural Strength: ≥ 180 MPa (ISO 10477 compliant)
  - Modulus of Elasticity: ≥ 4.5 GPa
  - Water Sorption: < 25 µg/mm³
  - Solubility: < 5 µg/mm³
- **Shade Range**: Full VITA Classical A1, A2, A3, A3.5, B1, BL1 (Bleach).
- **Occlusal Wear**: Gentle wear coefficient opposing natural human enamel, preventing wear of the antagonist arch.

### 2. Digital Complete & Monolithic Dentures
- **Clinical Indications**: Edentulous maxilla and mandible, immediate dentures, full-arch duplicate prosthetics.
- **Material Science**: High-impact monomer-reduced PMMA-grade photopolymer for denture bases, bonded or printed with high-wear cross-linked teeth.
- **Features**:
  - Zero polymerisation shrinkage (unlike heat-cured conventional acrylics which shrink ~7% linearly).
  - Superior suction and peripheral seal from exact digital tissue adaptation.
  - Same-day file re-print capability stored permanently in cloud archive.

### 3. Minimal-Prep Ceramic Veneers
- **Clinical Indications**: Aesthetic diastema closure, fluorosis correction, incisal edge wear, anterior smile redesigns.
- **Material Science**: Ultra-thin high-translucency aesthetic composite resin.
- **Margin Thickness**: As thin as 0.3 mm, requiring zero or minimal enamel reduction.

### 4. Stackable & Dual-Sleeve Surgical Guides
- **Clinical Indications**: Single-unit, partially edentulous, and fully edentulous guided implant placements.
- **Material Science**: Transparent, autoclavable Class I surgical resin.
- **Features**:
  - Integrated stainless steel or titanium master sleeves for pilot and fully guided drill systems.
  - Inspection windows for complete soft tissue seating confirmation.
  - High dimensional stability resistant to heat sterilization (121°C autoclave).

### 5. Clear Aligners & Orthodontic Movement System
- **Clinical Indications**: Class I malocclusion, anterior crowding, spacing, relapse correction, pre-restorative leveling.
- **Material Science**: Medical-grade multilayer polyurethane co-polyester with high elasticity and stress retention.
- **Features**:
  - Staged biomechanical planning conducted by licensed orthodontists.
  - Smooth scalloped gingival margins for superior patient comfort.
  - Delivered in complete numbered patient aligner kits.

### 6. Occlusal Splints & De-Programmers
- **Clinical Indications**: Nocturnal bruxism, temporomandibular joint disorder (TMD), myofascial pain, post-orthodontic retention.
- **Material Science**: Thermo-flexible biocompatible resin that softens at intraoral body temperature (37°C) for snap-fit retention without sore spots.
- **Features**: Monomeric purity preventing discolouration and odour absorption.
