Removable Prosthetics

The removable prosthesis arrives with structured prescription, scans, and documented design.

TrazaLab structures every removable case so the lab knows prosthetic type, missing teeth, material, retention method, and shade — before opening a single file.

Prosthetic Types

Four categories. Each with its workflow.

Each removable type has different clinical requirements. TrazaLab captures the right fields for each one — so nothing is assumed.

Metal Partial (RPD)

Cobalt-chrome framework with clasps on existing teeth. The most durable removable option. Indicated for multiple missing teeth with adequate abutment support.

5-8 year average lifespan

Yitzhaki et al. 2016 — PMID 27437367

Flexible Partial

Nylon-based (Valplast, TCS). No metal clasps visible. Esthetic solution for anterior gaps. Lighter and more comfortable, but harder to reline or repair.

High patient satisfaction

Evaluation of flexible RPDs — PMID 36826200

Complete Denture

Full arch replacement. Acrylic base (PMMA). Digital denture workflow available: from intraoral scan to milled or 3D-printed final prosthesis, eliminating wax try-in variability.

CAD/CAM dentures: better fit

Abuelnaga et al. 2021 — PMID 34400250

Implant Overdenture

Retained by 2-4 implants with locators or bar attachment. Combines implant stability with removability for hygiene. The standard of care for mandibular edentulism.

97% implant survival

Sadowsky 2007 — PMID 21597430

Platform

This is how a removable case arrives at your lab

The surgeon fills out the removable prescription in TrazaLab. You receive the complete case: prosthetic type, missing teeth, material, retention, shade, and all files attached.

No phone call. No WhatsApp audio. No guessing if the photos match the scan. Everything structured, everything in one place.

From scan to delivery — no wax.

The digital denture workflow replaces traditional impressions and wax try-ins with a predictable, repeatable digital chain.

Intraoral Scan

Replaces alginate impressions. Accurate, comfortable, repeatable. No stone models to ship or store. The scan goes directly to the lab through TrazaLab.

CAD Design

Framework and teeth designed digitally. The lab sees the full design before milling. Changes are made on screen, not in wax — faster iterations, documented revisions.

Digital Try-in

Virtual try-in or 3D-printed try-in before final fabrication. The surgeon verifies occlusion, esthetics, and fit without waiting for a wax setup.

Fabrication

Milled or 3D-printed. Consistent quality across every unit. No manual wax-up variability. The final prosthesis matches the approved digital design exactly.

Materials

Materials: what the data says

Published data comparing the four main removable prosthetic types. Not marketing — systematic review evidence.

Type	Material	Durability	Esthetics	Repairability	Best For
Metal Partial	Cobalt-Chrome	Excellent	Moderate	High	Long-term, multiple missing
Flexible Partial	Nylon / Polyamide	Moderate	Excellent	Low	Anterior esthetics, metal allergy
Complete Denture	PMMA Acrylic	High	High	Excellent	Full edentulous
Overdenture	Ti + Acrylic	Excellent	High	High	Stability + removability

Flexible partials are NOT recommended for long-term posterior rehabilitation. Nylon frameworks cannot be relined conventionally, and durability drops significantly after 3-4 years. For long-term posterior cases, metal partials or implant overdentures are the evidence-based choices.

Outcomes

Clinical data, not promises

Every number below comes from a peer-reviewed systematic review. Click the source to verify on PubMed.

Overdenture satisfaction

Patient satisfaction with implant overdentures vs ~60% for conventional dentures.

Thröneberry 2009 →

Average RPD lifespan

Mean functional lifespan for cobalt-chrome removable partial dentures with proper maintenance.

Yitzhaki 2016 →

Implant survival (overdenture)

Implant survival rate for overdenture abutments. Mandibular 2-implant overdenture is the standard of care.

Sadowsky 2007 →

Less bone resorption

Reduction in mandibular bone resorption with implant overdentures compared to conventional dentures.

Prescription Flow

The surgeon's prescription, step by step

Five structured fields. No free-text guessing. The surgeon selects, the lab receives — complete and validated.

Arch Selection

Upper, lower, or both. Each arch triggers its own prescription form with arch-specific fields and file upload requirements.

Prosthetic Type

Metal partial, flexible partial, complete denture, or implant overdenture. Each type activates different validation rules and required fields downstream.

Missing Teeth Identification

Tooth numbers selected on an interactive chart. For complete dentures, full arch is auto-selected. For partials, each missing tooth is mapped individually.

Material & Retention Preferences

Framework material (Co-Cr, nylon, acrylic), retention method (clasps, precision attachments, locators, bar), tooth shade, and gingiva shade — all from validated dropdown options.

Photos & Scans

Existing arch photo, occlusion photo, smile photo, and intraoral scans (.stl) — all attached to the case, not scattered across WhatsApp threads or email chains.

Quality Control

Validation before fabrication

Removable-specific checks the lab runs before processing. Structured in TrazaLab so nothing is missed.

Scan & Impressions

Arch coverage complete (full palate or alveolar ridge)

Opposing arch scanned or mounted

Bite registration included

Photos

Existing teeth documented (for partials)

Ridge condition visible

Occlusion photo from buccal view

Prescription

Prosthetic type confirmed (partial/complete/overdenture)

Missing teeth identified and mapped

Tooth shade and gingiva shade selected

Design

Retention method specified (clasps, attachments, locators)

Framework material confirmed

Special instructions documented (if any)
