Stop “Eyeballing” Gingivectomies. Digitally Guarantee the Biological Width.
Freehand gum contouring often leads to clinical asymmetry or, worse, violation of the biological width, causing chronic inflammation or frustrating tissue rebound (regrowth). China Dental Design offers a premium Crown Lengthening Guide CAD Design service that meticulously maps out exactly where the clinician needs to cut the soft tissue and, crucially, exactly where to reduce the underlying bone. Ensure your esthetic cases succeed from the foundation up.
Technical CAD Engineering Specifications
Our expert digital technicians combine advanced esthetic principles with strict periodontal biology to engineer a surgical guide that ensures long-term gingival stability:
Digital Esthetic Planning (DSD)
- Gingival Zeniths: We digitally align the zeniths of the centrals and canines to be perfectly symmetrical, with the laterals positioned slightly lower (0.5mm – 1mm), strictly following standard Digital Smile Design (DSD) protocols.
- Proportion Analysis: We mathematically analyze and target the ideal width-to-length ratio (75-80%) for the final crown or porcelain veneer.
Periodontal Biological Planning
- Bone Reduction Guide (Ostectomy): If your clinician is placing veneers, simply cutting the gum is rarely enough. We design a precision guide showing exactly how much bone to remove to safely maintain a 3mm distance from the new restorative margin to the bone crest.
- Dual-Guide / Stacked Option: We can engineer a stacked guide system: Layer 1 for the soft tissue Gingivectomy, and Layer 2 specifically for the Bone Reduction.
Advanced Clinical Applications
Our Crown Lengthening Guide CAD Design is considered essential for high-value cosmetic cases:
- Gummy Smile Correction: Predictably reducing excessive gingival display for a harmonious smile.
- Short Clinical Crowns: Safely exposing more sound tooth structure for adequate mechanical retention before prepping a full crown.
- Uneven Gum Lines: Harmonizing the soft tissue architecture before placing large anterior veneer cases (6-10 units).
100% HIPAA Secure Digital Workflow
- Secure Upload: Send Intraoral Scans (STL/PLY) + CBCT (DICOM, required if bone reduction is needed) + Full Face Smiling Photos via our 256-bit encrypted portal.
- Prescribe: Tell us the clinical goal (e.g., “Lengthen centrals to 10.5mm” or “Match zenith of #8 to #9”).
- Expert Design: We execute the design overnight natively in 3Shape or Exocad.
- Download & Print: Download the print-ready STL files the next morning and print immediately using your clear Surgical Guide resin.
