Ivoclar Cention N Starter Kit

• Mixing time (at 23 °C): 45–60 s
• Working time: 3 mins
• Setting time (self-curing): 5 min (From the start of mixing)

Isolation

• Begin by isolating the treatment area to maintain a dry and contamination-free environment. Use rubber dams or other appropriate isolation techniques.

Cavity Preparation

• Without Adhesive: Prepare the cavity following guidelines for amalgam fillings, including a retentive preparation design with retentive undercuts. Avoid unsupported enamel areas. Create a deep and wide isthmus, especially for Class II fillings. Use a beveled cavity floor to reduce tension peaks. Rinse and dry the cavity.
• With Adhesive: Prepare the cavity using adhesive technique principles. Preserve as much tooth structure as possible. Avoid sharp internal angles in caries-free areas. The cavity's geometry depends on the dimensions of the caries lesion or existing filling. Slightly bevel or round out enamel margins. Rinse and dry the cavity.

Pulp Protection/Base (if necessary)

• Depending on whether an adhesive is used:

Matrix and Wedge Placement

• If the cavity involves proximal areas, place a matrix band and secure it with wedges to create the desired tooth shape.

Conditioning and Bonding (if necessary)

• Depending on whether you're using Cention N with or without an adhesive, Condition the tooth structure and apply the dentin-enamel bonding agent.

Dispensing and Mixing

• Mix the Cention N material according to the recommended ratio of Powder and Liquid components, considering the cavity's size.

Filling and Shaping

• Place and shape the mixed Cention N material into the prepared cavity.

Finishing and Polishing

• After the material has polymerized, remove any excess material using suitable finishing tools, such as tungsten carbide finishers or fine-grit diamonds. Pay special attention to proximal areas.

Occlusion Check

• Examine the occlusion and articulation to ensure proper tooth alignment. Make any necessary adjustments to prevent premature contacts or undesired articulation paths.

• Ease of Use: Cention N simplifies dental restorations with no need for a primer, varnish, or curing device.
• Time-saving: It reduces the number of working steps, saving time for both practitioners and patients.
• High Strength: Cention N offers superior flexural strength for durable restorations.
• Esthetic: It provides a natural, tooth-colored appearance for pleasing results.
• pH Regulation: The material regulates pH during acid attacks, preventing demineralization.
• Remineralization: Releases fluoride and calcium ions for enamel strengthening.
• Self-Curing: It self-cures chemically, eliminating the need for external devices.
