Ivoclar Variolink N Intro Pack

Ivoclar Variolink N Intro Pack is an essential toolkit for dental professionals, primarily focused on restorative dentistry. This introductory package equips practitioners with vital components required for efficient and precise dental restoration cementation. Variolink N, a dual-cure and light-cure luting composite, is the central element of this pack. It is specially formulated to cater to the adhesive cementation of various dental restorations, particularly those made of glass ceramics, lithium disilicate, and composite resins. This makes it a versatile and reliable choice for a wide range of clinical cases. The kit includes essential materials such as the base and catalyst, Monobond N, and a low-viscosity liquid strip, ensuring secure and esthetic bonding between the restoration and natural teeth. Additionally, it provides various accessories to streamline the cementation process. The Variolink N Intro Pack is renowned for its esthetic prowess, shade stability, and adaptability. The wide spectrum of available shades allows precise color matching, while its compatibility with different restorative materials broadens its applicability. This pack is a critical resource for achieving outstanding esthetic and functional results in restorative dentistry.

Direction To Use: 

Removal of Temporary Restoration and Cleaning:

• Begin by removing any temporary restoration from the tooth cavity using appropriate dental instruments.
• Clean the cavity and the prepared tooth by removing any residue from the temporary luting composite. Use a polishing brush and an oil- and fluoride-free cleaning paste (e.g., Proxyt fluoride-free).
• Rinse the cleaned area with water.

Preparation of Restoration Surfaces:

• If you are working with composite or fiber-reinforced composite restorations, follow the manufacturer's instructions for blasting the restoration surfaces.
• If necessary, clean the restoration in an ultrasonic unit for about 1 minute.
• Thoroughly rinse the restoration with a water spray and dry it with oil-free air.

Application of Primer Agent:

• Apply a primer agent (e.g., Monobond N or Monobond-S) to the pre-treated surfaces using a brush or micro brush.
• Allow the primer agent to react for 60 seconds.
• Disperse the excess primer agent using a strong stream of air. Ensure that the surfaces remain uncontaminated.

Pre-treatment of the Cavity (for enamel and dentin):

• To protect adjacent teeth and facilitate excess material removal, use a matrix band in the proximal regions.
• Apply N-Etch (37% phosphoric acid gel) to the prepared enamel and, if necessary, to the dentin. Follow the recommended etching times.
• Remove the etchant gel by rinsing it vigorously with water for at least 5 seconds.
• Ensure that the dentin surface remains slightly wet and shimmering (wet bonding). Remove excess moisture with appropriate methods, such as an air gun or dry brush.

Application of Variolink N:

• Depending on the type of restoration (inlays, onlays, crowns, veneers), follow the specific instructions provided in the Intro Pack.

Polymerization (Curing):

• Polymerize Variolink N segment by segment, starting with the proximal margins.
• Use a curing light with the appropriate light intensity as recommended by the manufacturer. Follow the recommended curing times based on the light source.

Finishing and Polishing of the Restoration:

• Use finishing and polishing strips in the proximal regions to achieve the desired finish.
• Check occlusion and function and make any necessary corrections.
