The A+BCDE™ Protocol for Smile Rejuvenation

Not a veneer protocol. A philosophy for comprehensive smile design.

A beautiful smile should never come at the expense of healthy tooth structure, function, or the biology that supports it.

The A+BCDE™ (Airway Positive Biomimetic Comprehensive Dental Esthetics) Protocol is Dr. Keerti Sahasrabudhe’s comprehensive approach to smile design. Developed through decades of advanced education, clinical experience, and interdisciplinary training, it integrates airway-conscious treatment planning, biomimetic dentistry, comprehensive diagnosis, and cosmetic excellence into a single philosophy of care.

Dr. Keerti is one of fewer than 100 Fellows of the American Academy of Cosmetic Dentistry worldwide and an Accredited member of the Academy of Biomimetic Dentistry. Since 2015, she has incorporated airway evaluation into every comprehensive examination after being influenced by pioneers in airway-focused orthodontics.

Rather than asking, “How do we make the teeth look better?” the A+BCDE™ Protocol begins with a more important question:

“How can we create the most beautiful smile while preserving biology, function, and as much natural tooth structure as possible?”

This patient, a young dentist herself, sought out Dr. Keerti specifically for this comprehensive approach rather than pursuing conventional veneers.

Evaluation revealed a narrow upper arch, creating dark buccal corridors, a constricted smile, and tooth proportions that appeared long and narrow. Her width-to-length ratio measured approximately 69%, whereas proportions closer to 72-75% generally create a fuller, more balanced appearance.

A conventional veneer approach would have widened the teeth by reducing healthy enamel.

Instead, Dr. Keerti first expanded the dental arches. Expansion naturally created the spaces in between teeth needed to improve tooth proportions with additive porcelain veneers. So, not reductive treatment that cuts into teeth to create room for porcelain but in fact an additive, tooth-preserving solution!

The final treatment required only four minimally prepared veneers in the esthetic zone. The canines were left completely untouched because they already possessed excellent shape, size, shade, and proportion. Necessary restorative treatment was completed on the posterior teeth to replace failing dentistry.

By addressing the underlying problem first, the final treatment was more conservative, more biologically respectful, and produced a broader, more harmonious smile.

This case went on to receive Seattle Study Club’s national Best Case Wins award in recognition of its comprehensive diagnosis, interdisciplinary planning, conservative execution, and exceptional esthetic outcome.

The Five Principles of the A+BCDE™ Protocol

A — Airway PositiveEvery comprehensive examination includes an evaluation of facial structure, arch form, bite, and airway. When appropriate, treatment is planned to support healthy arch development while enhancing both function and esthetics.
B — BiomimeticHealthy enamel is irreplaceable.Treatment follows biomimetic principles by preserving natural tooth structure and using bonded, minimally invasive restorations whenever possible.
C — ComprehensiveEvery treatment plan considers the teeth, gums, bite, supporting bone, function, and long-term stability. Beautiful dentistry begins with comprehensive diagnosis.
D — Dental ExcellenceEvery restoration is individually designed with meticulous attention to shape, proportion, texture, translucency, color, function, and longevity.
E — EstheticsThe finest cosmetic dentistry is virtually undetectable. Every smile is designed to harmonize with the patient’s face, personality, and natural features.

More Than Cosmetic Dentistry

The A+BCDE™ Protocol reflects Dr. Keerti’s philosophy that exceptional esthetic dentistry begins with understanding the whole patient. By addressing underlying problems first and preserving what nature has already created, treatment becomes more conservative, more predictable, and ultimately more beautiful.
