A practical approach to selection is to first decidewhich restorative, or combination, is best for the indication

In general, the startingpoint for choosing whichrestorative to use is to havea good understanding ofthe characteristics of eachmaterial. These shouldthen be matched to theperformance requirementsdemanded by theindividual clinical situation,

Consider which restorative is best for

CLASS I CLASS II CLASS III

CLASS VCLASS IV CORE BUILD-UPBASE/LINING

particularly depending onwhether the restoration isin the posterior or anteriorregions of the mouth, andthe location and size ofthe cavity.

To describe the cavity,this guide uses thestandard Class I to V

classification systemaccording to 'G.V. Black'.However, this traditionalapproach is graduallybeing replaced by moremodern classifications, asit was based on surgicalremoval of the cariouslesion, followed bymechanical interlocking of

a restoration such asamalgam that needsretention. By modernstandards therefore, anyinitial lesion treated willbe overextended.Nowadays, because ofmore advanced adhesivetechniques morepossibilities are available.

But suitability forthe indication is not the

only concern; othercharacteristics of thematerial should also betaken into account.For example, it must besafe to use, so if a patientis known to behypersensitive to certainmonomers, non-resinousmaterials should beconsidered. Choosing amaterial which gives theright balance betweenperformance andease/cost in use, may alsobe important, particularlyif restorations are afrequent procedure forthe practice and patientturnover per hour isimportant. Using arestorative that is easy touse and can work in amoist environment maybe best option here.

To help you select

the type of restorativesthat are most appropriatefor particular clinicalprocedures, please referto the relevant tables inthe following pages.

Which restorative?

Amalgam

Amalgam has been usedfor many decades and yet,even today, it remainspopular among somedentists, particularly foruse in areas of highocclusal loading, such asposterior teeth. Essentiallymade from a mix of silveralloy and mercury,

amalgam is easy to use,offers proven results inlarger posterior cavities,and is generallyconsidered to be reliableand inexpensive, withgood durability and wearresistance.

However, amalgamdoes present a number ofdrawbacks that may becontributing to its decline.In certain situations, usingamalgam may requirehealthy or sound tissue tobe removed beyond thelimits of the caries lesion.Being silvery-grey metallicin colour, amalgam is notparticularly aesthetic,especially when used inthe visible regions of themouth, and its goodthermal conductivity cancause problems for somepatients with sensitive

teeth. Nowadays, safetyand environmental issuesare constantly underreview and this has led tothe implementation ofstrict regulations in somecountries to prevent itsuse and/or to reduce therisk of pollution by usingamalgam separators.

Composite resins

Composite resins arehighly popular as dentalrestoratives. When usedcorrectly, they provideexcellent aesthetics/colourmatching from theavailability of a wide rangeof shades and opacities aswell as good physicalproperties. Composite

resins are consideredparticularly suitable for allrestorations whereaesthetics are the mostimportant factor.

However, compositesare also known for beingtechnique sensitive. Forexample, they need to beapplied in a moist-freeenvironment, and requirethe use of multi-stepbonding agents. Shrinkageof the material from cavityfloors and walls mayoccur during and afterpolymerisation, and toensure that polymerisationshrinkage is reduced thematerial needs to beapplied in layers,especially for deepcavity restorations.If polymerisation isincomplete and sincethermal expansion of

composite is differentfrom tooth structure,microleakage of therestoration may occur, aswell as marginaldiscolouration andbacterial penetration.The majority of compositesalso do not release any

Compomers

A compromise between aesthetics and ease of use

Compomers are createdfrom a mixture ofcomposites and glassionomers in an attempt tocombine the advantagesof both material groups,namely the aesthetics andphysical properties of acomposite with the easeof use of a glass ionomer.

However, they stillrequire close attention totechnique. For instance,there may be insufficientchemical adherence ofthe compomer to theteeth so they require theapplication of a bondingagent. The incrementallayering technique mayalso be required for deepcavities because ofpolymerisation shrinkage.All this results in longerhandling times comparedwith glass ionomers. Beingsensitive to water uptake,the material might expandin the cavities potentiallyaffecting the performanceof the restoration. Anddespite compomerscontaining glass ionomer,the majority do notrelease sufficient fluoride.

GC Fuji II

GC Fuji II

B E N E F I T S

GCs first glass ionomerrestorative GC Fuji II,represents the epitome ofthis important group ofrestoratives. A self-curingconventional glassionomer, it gives goodaesthetic restorations that

are safe and effective forClass III and V cavities inanterior adult teeth, aswell as in deciduous teethin children. It may beused in a variety of otherindications also, such asthe treatment of rootsurface caries and cervicalerosions, or for a basebelow amalgam orcomposites.

What sets glass ionomerlike GC Fuji II apart is itsease of use. For instance ithas strong, intrinsicchemical adhesion todentin and enamel whichis unaffected by moisture,so there is no need tokeep the area dry and noneed for etching orbonding agents. The strongadhesion also creates anextremely good, long-lasting marginal seal that

helps to preventdiscolouration andbacterial microleakage.Glass ionomer releaseshigh levels of fluoride, isbiocompatible and therestoration becomesincreasingly resistant towear over time.

The Advantages

Strong, self-curing chemical adhesion to dentineand enamel.

Adhesion unaffected by moisture so no need forprotection such as rubber dam.

No need for etching or bonding agents.

Excellent, long-lasting marginal seal.

High fluoride release.

Good aesthetic results.

Preparation of toothPrepare tooth using standardtechniques. Extensive

mechanical retention is notnecessary. For pulp cappinguse a calcium hydroxide.

ConditioningTo remove the smear layer

after tooth preparation it isrecommended to apply GCCAVITY CONDITIONER tothe bonding surfaces for 10seconds (or GC DentinConditioner for 20 seconds)using a cotton pellet orsponge.

Washing and dryingRinse thoroughly with waterand remove surface moistureby blotting with a cottonpellet or by gently blowingwith an air syringe. Do notdesiccate as this will affectthe adhesion.

POWDER AND LIQUID

Dispensing

Dispense onto the mixingpad 1 level scoop of powderto 1 drop of liquidrepresenting a standardpowder to liquid ratio of2.7/1.0g. For accuratedispensing of powder, lightlytap the bottle against thehand. Do not shake or invert.Hold the liquid bottlevertically and squeeze gently.Close bottles immediatelyafter use.MixingUsing the plastic spatula,divide the powder into 2equal parts. Mix the firstportion with all of the liquidfor 10 seconds. Incorporatethe remaining portion andmix the whole thoroughly for15-20 seconds (total timewithin 30 seconds). Workingtime is 1 minute 45 secondsat 23C (73.4F). Highertemperatures will shorten theworking time.

ApplicationTransfer cement to thepreparation using a syringe orsuitable placementinstrument.

CAPSULE

ActivationBefore activating tap the sideof the capsule on a hardsurface to loosen thepowder. Press the plunger inon a hard surface until it isflush with the main body.

ProtectionAfter finishing apply afinal coat of GC FujiVARNISH or GC Fuji COATLC to protect the GIC duringthe first 24hrs.

FinishingAfter initial set, correct thecontour WITHOUT waterspray using standardtechniques. Apply GC FujiVARNISH or GC Fuji COATLC and wait for about 15minutes. Final finishing andpolishing under water spraycan now be carried out.Ideally finishing and polishingis performed 24hrs afterplacement.

Restorative techniqueAvoid air bubbles duringapplication. Form thecontour and place a matrix ifrequired during the first 2minutes of setting. Settingtime is 530" from start ofmixing. Once set, removethe matrix and immediatelyapply GC Fuji VARNISH(blow dry) or GC Fuji COATLC (Light Cure).

ApplicationUsing GC Capsule Applier

inject cement directly intothe cavity.

MixingImmediately set the capsule

into the mixer and mix for10seconds (+/- 4.000 RPM)
