OHI-S Gummy Smile and Masseter Reduction: Anatomy, Diagnosis & BoNT-A Protocols

Advanced Botulinum Toxin Training for Gummy Smile, Bruxism & Masseter Reduction

The OHI-S Gummy Smile and Masseter Reduction: Anatomy, Diagnosis & BoNT-A Protocols course is a focused clinical training program covering the anatomical assessment, diagnosis, patient selection, and Botulinum Toxin Type A (BoNT-A) injection protocols used in gummy smile correction and masticatory muscle modulation.

Presented by Rabia Sannam Khan, this 6-lesson, 1-hour 17-minute course combines facial anatomy, diagnostic principles, injection landmarking, dosing concepts, complication prevention, and clinical outcome assessment.

• Zygomatic facial nerve considerations
• Depth control
• Injection-point distribution
• Dosing protocols
• Masseter hypertrophy treatment
• Bruxism management
• Jawline contouring
• Avoiding risorius involvement
• Smile asymmetry prevention

Special attention is given to anatomical mapping to reduce the risk of unwanted effects on adjacent muscles and neurovascular structures.

Lesson 6: Therapeutic Results, Patient Selection & Evidence-Based Practice

The final lesson focuses on long-term clinical management and evaluation of aesthetic and functional outcomes.

Topics include:

• Treatment-result timelines
• Jawline contour evolution
• Structural facial slimming
• Bruxism-related symptom improvement

Why This Course Is Valuable

The OHI-S Gummy Smile and Masseter Reduction BoNT-A course combines two highly relevant areas of modern facial aesthetic practice within one concise clinical program.

Rather than focusing only on injection points, the course emphasizes the sequence of:

Anatomy → Diagnosis → Patient Selection → Injection Planning → Treatment → Outcome Assessment

This approach is particularly useful for clinicians who want to strengthen their understanding of the anatomical structures involved in gummy smile correction, bruxism management, and masseter reduction while reducing the risk of functional complications.
