Warren and Capp 1990 ideal properties,
? Low initial viscosity
? Set rigidly
? Quick position time
? Be dimensionally stable
? Resistant to distortion
? unswayed by disinfection procedures

Egasu et al 2008 no impression disinfection technique atomic number 6% effective. Benzoalkium chloride and gluteraldehyde more effective

Ockert-Eriksson et al (2000) - Polymeric materials most accurate

Eriksson et al (2002) no interocclusal record is most reproducible in dentate

Davies and Gray (2001) CR record at increased OVD to avoid involuntary mandibular deviation with contact

Utz et al (2002) reproducibility of CR records unachievable disdain method used, but variations probably clinically insignificant

Buonocore et al (1955)

Nakabayashi (1982)

Weak or strong acid etch
Primer HEMA, or 4-META stabilises collagen and allows penetration of resin
Resin bisGMA or UDMA

Long term problems senseless etching, decalcified dentin beneath resin, and collagen may degrade over abundant term, too dry collagen collapses.




Sugizaki (1991) showed etching, washing and drying caused dentine to collapse delinquent to loss of supporting hydroxyapatite

Kanca (1992) wet bonding systems

DBA classification
1- 3 feeling (conventional) systems
2- 2 step a) separate etch, then gear up and bond
b) etch and prime, then bond, so called self etch primers
3- adept bottle or all in one systems

Hume (1994) dentine excellent buffer for self etching systems

Micromechanical bonding of resins or so collagen fibres exposed by demineralisation of intertubular dentine

GIC invented Wilson (1972)

Mitra (1991) added water soluble resins

GIC setting
1- acid attacks glass particles
2- surface degradation of the glass and grow of metal ions, fluoride and silicic acid
3- metal ions react with carboxyl groups of acids...If you want to stool a full essay, order it on our website: Orderessay
