Fundamentals of the Kois Concept: Diagnosis and Risk Management. Module 1. Hands-on Workshop

This course launches a three-module training program on the Kois Concept — one of the most systematic and evidence-based philosophies in modern prosthetic and aesthetic dentistry, developed by John Kois.

The Kois Concept is a clinically driven approach grounded in risk management, precise diagnostics, and a deep understanding of the relationship between function, aesthetics, and biomechanics.

The first module is dedicated to the foundation of the entire concept — systematic diagnostics and clinical data collection. You will learn a clear patient analysis algorithm that enables the identification of key risks at the planning stage and allows treatment to be built on a solid, objective foundation.

Key course topics:

— Mastery of Clinical Data Collection
The “Kois 10” protocols — ten critically important clinical parameters, including standardized photographic documentation.
 

— Risk Management (P-B-F-D)
Systematic screening of periodontal, biomechanical, functional, and dento-facial risks.
 

— Kois 10-Step Diagnostic System
A step-by-step algorithm to pinpoint the “weakest link” and prevent clinical complications.
 

— Dento-Facial Analysis
Evaluation of aesthetic exposure (E-max), resting lip position, gingival contour, and anterior-posterior tooth positioning for facial harmony.
 

— Function and Diagnostics
Exploring the relationship between tooth form and function, and the role of the Kois deprogrammer in functional analysis.

During the hands-on workshop, participants will practice:
 

— Working with the Kois Glasses facial analyzer
— Fabricating and adjusting the Kois Deprogrammer (KD)
— Recording centric relation (KD-bite)
— Facebow registration and mounting casts in the articulator
— Clinical case analysis using the Panadent articulator.

The course lecturer, Tak-On Tse Ryan, is a student and devoted follower of John Kois, a practicing clinician, and educator. Dr. Ryan is a summa cum laude graduate and a mentor at the Kois Center in Seattle. He is also one of the few international mentors to co-author a landmark clinical publication with Dr. John Kois: “Digital Smile Design and the Dento-Facial Analyzer: Optimizing Aesthetics While Preserving Tooth Structure.”

This module establishes the foundation for the following two modules of the program and is a mandatory step for clinicians aiming for predictable, stable, and aesthetically grounded dentistry.

Program

Day 1

Theory (December 7)

Data and Risk Management (09:00–12:30)

— Mastery of Clinical Data Collection:

- Precise “Kois 10” registration protocols — ten key clinical parameters, including standardized photographic documentation.

— Four Categories of Risk (P-B-F-D):
 

- Comprehensive screening of periodontal, biomechanical, functional, and dento-facial risks.

— Kois 10-Step Diagnostic System:
 

- A structured workflow aimed at minimizing clinical complications and identifying the “weakest link.”

— Dento-Facial Risk Analysis:
 

- Emma Analysis: E-max (aesthetic exposure), resting lip position, gingival margin contour
- AP Position: determining the optimal anterior-posterior tooth positioning for facial harmony.

Aesthetic Logic and the Kois Concept (13:30–17:00)

— Clinical Interface: Panadent and Kois Analyzer

— Dento-Facial Analyzer:
 

- Why traditional facebows lack precision and how the Kois system achieves 100% predictability.

— Integration with the Articulator:
 

- Transferring facial data into the Panadent articulator.

— Traditional Occlusion vs. Kois Occlusion:
 

- Comparing classical gnathology with the evidence-based, “frictionless” Kois concept.

— Introduction to the Kois Concept:
 

- The dynamic relationship between tooth form and patient function
- Kois Deprogrammer: scientific rationale for its use and its role in functional diagnostics.

Day 2

Hands-on (December 8)

— Kois Glasses:
Working with the Kois Facial Analyzer to record and align the maxillary plane relative to the horizon / natural head position.

— Kois Deprogrammer (KD):
Step-by-step clinical fabrication, adjustment (ADJ), and delivery to the patient.

— Precise Bite Registration:
Mastering the KD-bite to obtain a reproducible physiologic centric relation record using the deprogrammer.

— Facebow:
Clinical demonstration and hands-on practice of Kois protocols for facebow registration and cast mounting in the articulator.

— Clinical Case Demonstration:
Case discussion and analysis using the Panadent articulator.
