Rationale for using a SSC


are used to restore

primary molars in which

the failure of an amalgam

or composite restoration

is clear in your mind



The use of SSC is indicated in

cases in which the prognosis for

long term success of ldquoregularrdquo

restorations is reduced by a high

possibility of

a restoration fracture

b recurrent caries

Extensive caries destruction

An adequate

isthmus is

difficult to obtain

Multi-surface restorations


Preformed metal crowns

demonstrate greater

longevity and reduced re-

treatment need compared

with (multi-surface)

amalgam


The literature demonstrates evidence

of a more favorable outcome for SSCs

than for amalgam restorations in

primary molars requiring multi-surface

restorations

Stainless steel crowns (Unitek and Rocky

Mountain) crowns composition consist of 17-19

chromium 9-13 nickel and 008-01 carbon

Nickel based crowns (Ion Ni-chro from 3M)

composition consists of 76 nickel 8 iron 004

4 Allergy to nickel

Nickel is one of the most common

causes of allergic contact dermatitis

and produces more allergic reactions

than all other metals combined There

may be a risk of sensitizing patients

to nickel with long-term exposure to

nickel-containing appliances as in

orthodontic therapy Bass JK Fine H Cisneros GJ Am J Orthod Dentofacial Orthop 1993 Mar103(3)280-5

4 Allergy to nickel ()

Nickel has its

problems with human

biochemistry

Children have to start

wearing glasses within

a few months of

receiving the crowns




If your child becomes

cranky and misbehaves

after the crowns were

placed while previously

he had a pleasing

personality check it

out

Rationale for SSC tooth

preparation and adaptation

Flexibility easily bent or shaped

Elasticity the tendency of a body to

return to its original shape after it

has been stretched

The tooth preparation and crown

adaptation of SSC in primary (and

permanent) molars is based (among

other) on the crownrsquos

bull Preformed metal crowns are flexible and

elastic (they snap)



bull The tooth cervical bulge is ldquosurroundedrdquo

by the crown



a do not require the retention

features that are incorporated in

cavity design of cast crowns

b obtain their retention from the

flexibility and elasticity of the

thin contoured and crimped

crown margins and

cementation

Polish the crown

with a heath less

Due to carious proximal contact loss

the crown that fits M-D may be too

small B-L this may be solved with more

buccal or lingual reduction













Too high

Fits MD but does not cover the buccal
