What Dental Equipment is better when fillings with teeth ?

Short-term use of the material, such as for the temporary  Dental Equipment  closure hole material in the treatment process, eugenol zinc oxide cement powder may be used within 2 weeks, the zinc phosphate cement powder can be used for less than six months; long-term use of the material, i.e. a permanent filling material, defect dentin in the hole instead of long-term retention, such as silver amalgam, composite resin.
Silver amalgam: the interaction of mercury and silver-tin alloy powder amalgam compounds, the clinical use of the maximum. Need to withstand occlusal force used for Class I, II class hole and do not have to consider the aesthetic Class V; Taoka ring abutment hole; dental crown after post and core or full crown restorations inner layer. Dental amalgam should maintain a certain volume, in order to withstand the occlusal force without break; silver amalgam and tooth structure does not have the cohesiveness, box-shaped hole should be prepared, well-designed retention form, so both fit closely fitted to each other, good moisture barrier to amalgam in dental firm and lasting.
Composite resin: organic synthetic resin plus a large number of specially treated inorganic filler material, and it is by means of the   Dental Polisher   teeth surface treatment technology, bonded to the tooth tissues used for Class III-dong, V hole filling; also has a high-strength composite resin can be used for posterior teeth Class I, II class hole filling. Bonding technology also fixes the Class IV holes and serious dental defects teeth. Photosensitive cured composite resin color stability, strong adhesion, especially suitable for front teeth esthetic repair; chemically cured composite resin, easy to operate, although slight color change (palatal) side of the hole for the rear teeth and front teeth tongue also suitable.
Polycarboxylate cement (also known as polyacrylic cement): is a bottom and the anchor material. The bottom of the material  tooth polisher   can be used for holes, hole material sealed within six months, the root canal filling material can be used for the adhesive cements tooth crown and bridge repair, excipient as periodontal plug Governance agent.
The glass ion polymer cement: a light pulp stimulation of dental hard tissue adhesion, but the strength of silver amalgam multipurpose material. Applicable to Class III, V class hole for deciduous teeth filling for the a cavity sealer to prevent dental caries.
Zinc-phosphate cement: also known as long-lasting cement, zinc cement. Bearing material for upper bunk to the bottom of the   Dental Air Syringe   deep hole, cavity sealing material in less than six months, is also used in dental restorative crown and bridge repair.
