What is the ESP (Esthetic Simplified Predictable) Denture Technique?
ESP, which stands for Esthetic Simplified Predictable, is the proprietary full-denture system ROE developed in partnership with Ivoclar to make complete-denture fabrication more predictable. ROE notes that full dentures for edentulous patients remain one of the most challenging procedures in dentistry, and that unpredictable outcomes have historically made many dentists reluctant to accept denture patients despite growing demand. ESP is engineered to improve those outcomes with virtually no new chairside procedures required of the practitioner. It changes what the lab delivers and when, not how the dentist works.
The defining feature of ESP
What the practitioner receives at the bite registration appointment is a processed Ivocap final base, rather than a simple wax-rim baseplate. This single change has two effects. First, it gives the patient an early, real verification of the fit and comfort of the actual final base. Second, it provides a rigid, stable base for an accurate bite registration. Any necessary adjustments to the final base are made at this appointment.
Because the base is verified at bite registration and again at try-in, the patient experiences the true fit of the denture 2 to 3 times before final seating, which is what makes the seat appointment trouble-free and drives higher patient satisfaction.
The ESP process combines several specific lab techniques. The table below maps each element to its clinical purpose.
| ESP Element | What it does |
|---|---|
| Processed Ivocap base at bite appointment | First in-mouth verification of fit; stable base for accurate bite registration; final-base adjustments made here |
| Horizontal Average Plane Guide mounting | Casts mounted following anatomical landmarks for accurate, repeatable positioning |
| Stratos articulation system verification | Mechanical verification of balanced lingualized occlusion, plus curve of Spee and curve of Wilson |
| Tissue models (duplicate master casts) | Ensure precise denture-border accuracy; tissue-bearing acrylic is left untouched in the lab |
| Try-in (2nd verification of fit) | Patient re-verifies fit; final processing affects only the acrylic around the teeth |
| Ivocap premium injection processing | Eliminates manufacturing errors and porosity in the final base |
| Lingualized occlusion (standard) | Provided as standard for superior chewing efficiency and stability |
Why "tissue-bearing acrylic is untouched" matters
Because the intaglio (tissue-bearing) surface is verified and then left undisturbed during final processing, with only the acrylic around the teeth finalized, the fit the patient approved is the fit they receive. This is the mechanism behind ESP's "maximum flexibility": the lab can refine tooth set-up and esthetics in response to try-in feedback without compromising the verified tissue fit.
ROE reports that clients have used the ESP removable system for several years to fabricate pre-fit prosthetics that minimize chairtime and ensure patient satisfaction. ROE also offers an ESP Denture Technique Report and an ESP Denture Steps resource for practitioners who want the full protocol detail.
