Cellulose Strips

Cellulose Strips, also marketed as transparent celluloid strips or mylar matrix strips, are ultra‑thin, highly flexible and crystal‑clear plastic bands specifically engineered for restorative dentistry. Each strip is composed of reinforced cellulose acetate, giving it the strength required to maintain separation between adjacent teeth during resin-based procedures while remaining transparent enough for the operator to monitor the restoration.

In practice, Cellulose Strips serve as a separator matrix that locks in the margins of a filling, guaranteeing clean edges, smooth surfaces and a natural tooth contour after composite or resin placement. The primary advantage of this product is its ability to eliminate marginal irregularities and contamination, ensuring professional‑grade outcomes whether a clinician is working on a class II or class III cavity.

Key Features

• Made from high‑performance cellulose acetate, providing excellent optical clarity and no interaction with bonding agents.
• Ultra‑thin film at 0.13 mm thickness, preserving the natural contour of the cavity while giving a sturdy barrier.
• Pre‑cut widths ranging from 5 mm to 12 mm, allowing precise adaptation to cavity geometry.
• Flexible yet durable; can be molded around tooth anatomy without tearing.
• Transparent matrix allows direct visual inspection of margins during composite placement.
• Single‑use, pre‑sterilized packaging reduces cross‑contamination risk.
• Easy to handle; includes a built‑in fold and groove design for quick placement and removal.
• Compatible with all primer and adhesive systems used in modern composite workflows.
• Pack of 50 strips per carton, each individually sealed for sterility and long shelf life.
• Non‑sticky surface ensures the strip stays in position without adhesive residue.

Clinical Uses

• Class II restorations – maintaining a barrier between the prepared tooth and the opposing cusp during composite buildup.
• Class III reclinations – separating the opposing enamel margin from the cavity walls.
• Dentin restoration – providing a clean, uncontaminated surface prior to bonding.
• Fluoridation of margins – keeping the strip in place while rinsing and fluoride application occur.
• Margin refinement – enabling high‑contrast visualization of the restoration edge for ease of sealant finishing.
• Provisional restoration assembly – used as a temporary matrix before definitive composite placement.
• Operation of orthodontic bonding protocols – ensuring brackets do not interfere with resin flow.
• Lab workflow – technicians use the strip to mimic in‑office matrix conditions during handlay composite testing.

Why Dental Professionals Choose Cellulose Strips

• Provides precise, clean margins that reduce the likelihood of marginal leakage or secondary caries.
• Transparent film offers direct visual control over contour, essential for esthetically demanding per‑opercular work.
• Pre‑sterilized packaging eliminates the need for additional sterilization steps, saving time in clinical settings.
• Consistent width selection (5–12 mm) matches the most common cavity dimensions found in routine restorative work.
• Material’s non‐adhesive surface limits the need for extra cleaning chemicals and keeps the field free of debris.

Who Should Buy Cellulose Strips?

• Private dental practices seeking reliable matrix solutions for routine restorative procedures.
• Dental laboratories requiring standard matrix materials for handlay composite models.
• Hospital dental departments providing inpatient restorative services.
• Academic teaching clinics needing a consistent teaching tool for matrix use and margin visualization.
• Dental equipment distributors looking to supply a high‑quality, in‑house matrix product to end users.
