EAP® Abutments

IDENTITY & OVERVIEW

EAP® Abutments are patient-specific dental implant abutments designed by dentists. The system uses a unique titanium shell ("bowl") design where titanium is always in direct contact with the gingiva, while aesthetic materials are protected behind the titanium inside the shell.

DETAILED PRODUCT SPECIFICATION

Material & Construction

• Material: Titanium only
• Design: Thin, highly stable titanium shell ("bowl/housing")
• Manufacturing: Patient-specific, CAD/CAM compatible
• Digital workflow: STL-based

Layer Concept (3 layers)

1. OUTER LAYER (Gingiva contact): Titanium – always in direct contact with soft tissue
2. INNER LAYER (Inside titanium shell): Aesthetic material – ceramic, polymers, or 3D-printed crown materials (workflow dependent)
3. INTERFACE LAYER (Spring edge): Toward ceramic – minimizes adhesive gap between titanium and aesthetic material

Key Design Principles

• Adhesive interface (cement/adhesive gap) positioned as far away from bone as possible
• Patient-specific emergence profile ensures optimal fit and biological safety
• Spring edge toward ceramic minimizes adhesive gap
• Extended Anatomic Platform geometry maximizes distance between adhesive and bone

CLINICAL ADVANTAGES

1. Recession fix in 5-10 minutes (instead of complete remake)
2. Titanium always at gingiva = biocompatible, no monomer release at tissue
3. Adhesive interface far from bone = reduced risk of toxic cement near bone
4. Patient-specific = optimal emergence profile for each patient
5. Compatible with robotic implantology and 3D-printed crowns

BIOLOGICAL SAFETY CONCEPT (DETAILED)

Problem: Toxic Cement Near Bone

Traditional cemented abutments risk cement residue near the bone crest, which can cause:

• Peri-implantitis
• Bone loss
• Soft tissue inflammation
• Need for implant removal in severe cases

EAP® Solution

The Extended Anatomic Platform design addresses this through geometry:

1. The patient-specific emergence profile extends the distance from the abutment connection to the crown margin
2. This positions the adhesive interface (where cement is applied) as far away from the bone as possible
3. The spring edge toward ceramic minimizes the adhesive gap itself
4. Even if minimal cement excess occurs, it is far from the bone crest

Problem: Monomer Release at Gingiva

Resin-based materials in direct contact with soft tissue continuously release monomers (Bis-GMA, UDMA, TEGDMA, HEMA) that are cytotoxic.

EAP® Solution

• Titanium is always the material in contact with gingiva – never resin
• Aesthetic resin/ceramic material is protected behind titanium inside the shell
• Zero monomer release at the tissue interface

RECESSION FIX PROCEDURE (DETAILED)

Problem

When gingival recession occurs with traditional systems:

• Titanium or metal becomes visible at the gingival margin
• Aesthetically unacceptable for the patient
• Conventional solution: Complete remake of the restoration (expensive, time-consuming, multiple appointments)

EAP® Solution: 3-Step Chairside Fix

Step 1: Identify the area where titanium shell is visible due to recession Step 2: Remove titanium shell LOCALLY (only at the visible area, not the entire shell) Step 3: Polish the exposed aesthetic material underneath Result: Aesthetics restored in typically 5-10 minutes

• No complete remake needed
• No laboratory involvement needed
• Single appointment
• Minimal cost for the patient
