Medicem Glass Ionomer Luting Cement

Product Name: Medicem Glass Ionomer Luting Cement
Brand: Promedica
Product Type: Permanent Glass Ionomer Cement for Luting / Cementation 

1. General Description

Medicem is a micro-fine glass ionomer luting cement formulated for permanent cementation of indirect dental restorations. It provides a thin cement layer with excellent adhesion and long-term clinical performance in fixed prosthodontics. The cement is supplied as a powder and liquid system that requires mixing prior to use.

2. Clinical Indications

Medicem is indicated for:

• Cementation of crowns and bridges

• Luting of inlays and onlays

• Attachment of orthodontic bands

• Fixation of pins and posts
  It is suitable for routine prosthodontic cementation procedures requiring predictable and stable bonding to tooth structure. 

3. Key Technical Features

• Micro-fine film thickness (15-25 µm): Ensures accurate seating and minimal interference with occlusion. 

• Strong adhesion to enamel and dentin: Chemical bonding reduces risk of micro-movement. 

• High compressive strength and low solubility: Supports long-term stability in the oral environment. 

• High fluoride release: Contributes to remineralization and helps reduce risk of secondary caries adjacent to the restoration margin. 

• Low acidity and biocompatibility: The comparatively high pH results in reduced irritation of pulpal tissues and improved clinical tolerance. 

• No temperature rise during setting: Minimizes thermal stress to the tooth structure during setting. 

4. Handling & Application

• Mix the powder and liquid components according to manufacturer instructions to form a smooth, homogeneous cement paste.

• Apply a thin layer of the mixed cement to the internal surface of the indirect restoration.

• Seat the restoration and maintain appropriate pressure until initial set.

• Remove excess cement after initial setting phase.

• Final set occurs according to glass ionomer cement kinetics; follow manufacturer guidance for working/setting times.
  (Detailed mixing ratios and times are available in the official product technical documentation.)

5. Packaging

• 35 g powder + 15 ml liquid set (standard).

• Some sources note a smaller 15 g + 7 ml version.
  (Medicem Aqua is a water-mixable anhydrous variation available separately.) 

6. Clinical Advantages

• Reliable permanent cementation for prosthetic restorations.

• Predictable handling and adhesion for routine prosthodontic procedures.

• Radiopaque and clinically verifiable seating due to consistent film thickness.

• Fluoride release supports preventive action around restoration margins.
