ANSWERS

What materials are used for milled provisionals?

Milled provisionals are typically fabricated from PMMA (polymethyl methacrylate) pucks for short-term wear up to 6 months, or from reinforced composite resin pucks like Telio CAD or VITA CAD-Temp for long-term provisionals lasting 12 months or more. Multi-layer PMMA discs deliver gradient shade for anterior cases.

THE SHORT ANSWER

THE FULL PICTURE

Why it works this way

The two material families that cover almost every milled provisional case

Most milled provisionals shipped from a digital lab fall into one of two material categories: PMMA or reinforced composite. PMMA pucks (polymethyl methacrylate) are the workhorse for short-term provisionals, typically rated for intraoral wear up to 6 months. Brands include Yamahachi PMMA, Ivoclar Telio CAD, and ZirkonZahn Temp Premium. Multi-layer PMMA discs, which carry a built-in incisal-to-cervical shade gradient, are the standard pick for anterior single units and short-span bridges where esthetics matter more than longevity.

How long can a PMMA provisional stay in the mouth?

Manufacturer indications for standard PMMA pucks typically cap intraoral wear at 6 months. Reinforced composite pucks like Telio CAD and VITA CAD-Temp extend that window to 12 months or more under normal occlusal load. Past those thresholds, surface wear, plaque retention, and microfracture risk climb sharply. For staged full-arch cases that run 9 to 18 months, the reinforced composite is the defensible choice. Confirm the expected wear window on the Rx so the lab selects accordingly.

Can milled provisionals be used for full-arch implant cases?

Yes. Milled provisionals are the standard for All-on-X healing phases, which typically run 3 to 6 months between immediate-load placement and final prosthetic delivery. The provisional needs to survive full occlusal function during osseointegration, so reinforced composite pucks are preferred over straight PMMA for this indication. Multi-unit screw-retained provisionals are designed with reinforced framework geometry and titanium insert seats to handle the load and allow chairside relines if soft tissue contours shift during healing.

What is the difference between monolithic and multi-layer PMMA?

Monolithic PMMA pucks are a single uniform shade through the full thickness, which keeps cost low and works well for posterior provisionals where shade gradient is not visible. Multi-layer PMMA discs are manufactured with a pre-blended shade transition from incisal to cervical, mimicking the natural value gradient of a vital tooth. Multi-layer is the standard for anterior provisionals and any case in the esthetic zone where the patient or referring dentist will judge the result on shade match.
