Description

Cention N is a radiopaque, self-curing filling material with light-curing option, which releases fluoride, calcium and hydroxide ions. It is suitable for use as a full volume replacement material in restorations for Class I, II and V cavities. Cention N can be optionally cured with light in the wavelength range of 400–500 nm.
Cention N offers tooth-coloured esthetics together with high flexural strength. The new filling material belongs to the materials group of Alkasites. The patented alkaline filler increases the release of hydroxide ions to regulate the pH value during acid attacks. As a result, demineralization can be prevented. Moreover, the release of large numbers of fluoride and calcium ions forms a sound basis for the remineralization of dental enamel. The initiator system enables good chemical self-curing.

Directions To USE

Application 1. Isolation Appropriate isolation is required. 2. Cavity preparation 2.1 Cavity preparation when using Cention N without an adhesive When using Cention N without an adhesive, the preparation guidelines for the placement of amalgam fillings apply (retentive preparation design, resistance form). Retentive undercuts need to be prepared in all areas of the cavity. Enamel portions not supported by dentin must be avoided. In order to prevent fractures of Class II fillings, the area of the isthmus should be sufficiently deep and wide: on the occlusal/proximal aspect it should be at least 1.5 mm in depth, and on the buccal/oral aspect at least half the cuspto-cusp distance. The cavity floor should feature a bevel from the occlusal to the proximal aspect in order to reduce tension peaks. Enamel margins should not be bevelled. Subsequently, rinse the cavity with water spray to remove all the residue and dry with water- and oil-free air. 2.2 Cavity preparation when optionally using Cention N with an adhesive The cavity is prepared according to the principles of the adhesive technique, i.e. by preserving as much of the tooth structure as possible. Do not prepare sharp internal angles or additional undercuts in caries-free areas. The geometry of the cavity is predetermined by the dimensions of the caries lesion or the old filling. Slightly bevel or round out the enamel margins using finishing diamonds (grit size 25–40 µm). Subsequently, rinse the cavity with water to remove all residue and dry with water- and oil-free air 3. Pulp protection / Base If no adhesive is used, areas close to the pulp should be selectively coated with a calcium hydroxide preparation (e.g. ApexCal®). If an adhesive is used, a cavity liner is generally not necessary. Only in very deep cavities, selectively coat the area close to the pulp with a calcium hydroxide-based preparation (e.g. ApexCal®) and cover it with pressureresistant cement (glass ionomer cement, e.g. Vivaglass® Liner) before applying the dentin-enamel bonding agent. Do not cover other cavity walls, since they can be used to support the bond with a dentin-enamel bonding agent 4. Placing the matrix / interdental wedge If the cavity includes proximal areas, place a matrix band and secure it with a wedge. 5. Conditioning / Applying the dentin-enamel bonding agent When using Cention N without an adhesive, do not condition the tooth structure with phosphoric acid. Condition and apply the dentin-enamel bonding agent according to the Instructions for Use of the product in use. Ivoclar Vivadent recommends using the dentin-enamel bonding agent Tetric® N-Bond Universal or Tetric® N-Bond (in combination with phosphoric acid etching). 6. Dispensing and mixing The mixing ratio for a small cavity is: 1 measuring scoop of Powder and 1 drop of Liquid (this corresponds to a weight ratio of 4.6:1). For larger cavities, a mixing ratio of either 2 measuring scoops of Powder and 2 drops of Liquid or 3 measuring scoops of Powder and 3 drops of Liquid should be used. 7. Finishing / Checking the occlusion After polymerization, remove excess material with suitable tungsten carbide finishers or fine-grit diamonds. Remove proximal excess with diamond or tungsten carbide finishers or using finishing strips or flexible finishing discs. Check the occlusion and articulation and grind in the necessary adjustments to prevent premature contacts or undesired articulation paths on the surface of the restoration.
