Buccal and lingual bulges of primary molars should be reduced to prepare for a SSC(especially buccal). Look inside the best-fitting prefabricated crown and prep your tooth to fit it.

Fuji I cement is strong enough to retent the SSC. After determining the mesio-distal dimension, we should make the tooth fit the crown.

While cementing the SSC, seat the crown from lingual to buccal, it should extend 1-1.5mm subgingivally.
If it doesnot seat, first check occlusal and then buccal cervical prominence (reduce if necessary).

When restoring a tooth, it's imp to reduce the buccal bulge particularily the buccal of primary molars. Also, when seating a ss crown, we seat it from Lingual to Buccal.

There is no scientific evidence that maintianing the buccal bulge will increase crown retention. So ahead and prep.

Unitek crowns are steel, not pre-contoured and not pre-trimed and would require more time and effort to properly fit than 3M Ion crowns which are pre-trimed and pre-contoured.

It's important to provide kids w/ restorations that wears and shifts since teeth's occlusion shift a lot also.

SSC are used by dentists to restore primary teeth that has lesions in 3 or more surfaces. The crown itself must mimic the original contours of the tooth so you have to reduce tooth structure on all surfaces.

Prep the tooth to fit the crown. Ion nickel steel crowns are preferred since they're are pre-crimped, pre-contoured, and pre-trimmed.

SSC for primary posteriors are really easy: just prep the tooth to fit the properly M-D sized preformed anatomic crown to 1.5 mm sub-g & cement w/ GI. If compensating for lost space due to caries for a lower 1st molar, restore with the contralateral upper 1st molar crown.

We should avoid doing fillings of more than 2 surfaces in primary teeth. The ideal treatment would be placing a ssc, following the parameters in the tooth preparation, to obtain a high success.

Removing the buccal bulge in a SCC prep does not compromise retention. Also, use Fuji 1 to cement the crown .

The buccal bulge should be removed in a SS crown prep and the SCC should be seated lingual to buccal.

3M Ion crowns are precontoured and pretrimmed but uniteck crowns are not pretrimmed and precontoured so need more effort and seating a stainless steel crown is from lingual to buccal.

Whenever adjacent crowns are needed then at least 1.5mm space is needed when doing proximal reduction between teeth. The gingival margins of crowns can be no more than 1.5mm subgingivally.

MOD restorations do not survive long in pedo patients. Instead, opt for a SSC everytime.

SSC should have the margin extending 1.5mm into sulcus- creating slight blanching of the gingiva.

Lesions of more than 2 surfaces should not be restored with a 2+ restoration (MOD)in pediatric patients... instead a SSC is the better option and should be placed. SSC preps are easy! :)
Stephanie Morphis #154

SSC needs bucc and ling reduction, which the concept that no buucc reduction would increase retention is wrong. Also we need subgingival preparation and pick a ssc which goes to 1-1.5 mm subgingivally and makes a little blanching.

SSC is indicated for primary teeth when more than two surfaces needs restoration. Take the 245 and 260-6c bur, reduce 1-1.5mm occlusally, prep around the crown to mirror the original shape of the tooth down to the gingival level. Fit SSC crown M/D, and seat it 1mm below gingiva lingual to buccally.
Jing Lee #144

Smooth prep finish? No way. For a strip crown, roughen the tooth's surface with a carbide bur to get more retention. And if you didn't know, anterior SCC's are a "cultural" thang.

SSCs are one of the easiest crowns to place and one of the most stable temporaries. In addition, it very cost effective compared with the acrylic temps. It just requires learning how to place them properly.

Unlike permanent teeth where crowns are made to fit the preparation, in decidous dentition it is the other way around, in that you prep the teeth to fit the premade crowns.

When preparing a primary tooth for a SSC, reducing the cervical bulge not only helps retain anatomic form of a tooth, but also may prevent crown overhang and gingival irritation.

After cementing a SSC, evaluate the following:
marginal ridge height match adj teeth; margin closely adapted to tooth; restored proximal contact and normal occlusion; margin extend 1.5 mm into sulcus (slight blanching); remove all cement.

SSC's should be used in cases where more than two surfaces need restoration in primary teeth. Also, primary teeth are prepped to fit the crown as opposed to the reverse in permanent teeth preparation where the crown is fitted to the prepped tooth.

The SSC is a highly effective/efficient way to restore teeth in kids w/ high caries rate. Failure is almost zero for SCCs when done correctly (failure even for class IIs in kids is fairly high). Chairtime is minimal, payment is maximal,& durability is maximal.
Sean Young #192

Anonymous said...

Primary teeth requiring more than a two-surface restoration, should be restored with a SSC. The failure rate is much higher for multiple surface restorations with amalgam or composite than for a SSC. The SSC crown prep should include reduction of the buccal cervical buldge... despite the outdated techniques taught for the "Rocky Mountain Crowns".

It is easier to do a SSC than a class 2 on a primary tooth. If multiple proximal lesions are involved (MOD), then it is indicated to do a SSC.

Ion-style (3M) crowns are pre-trimmed, pre-contoured, pre-crimped, and more flexible; harder nickel steel.

Unitek-style crowns require trimming, contouring and crimping; more time consuming to produce quality restoration.

Prep B and L for better retention and Nickle ion crowns are in favor since it is precontoured.

It is important to reduce the buccal and lingual bulges of primary molars for the preparation of a SSC. Use Ion Crowns because they are already more anatomically correct

We have to prepare the bucal and lingual surfaces for a better outcame of a SSC. Also, if the crown is a little bit to high it will adjust in time because the temporary teeth are more adaptable than the permanent ones.

When prepping for a SSC, a #169 bur should generally be avoided when doing proximal reduction because it has a flat end, therefore it will create a ledge. Instead, one should use a tapered diamond bur.

No scientific evidence exists to support the idea that maintaining the buccal bulge will increase crown retention. In fact, all scientific evidence is to the contrary. Reduction is necessary to retain normal anatomical form and prevent gingival irritation, crown overhang, and increased failure.

When you prep a tooth for a SSC, it is best to leave a course/rough finish so that there is an increase in surface area leading to better retention of the crown.

If you cut a child's gingiva while trying on a SSC, it's ok. A pocket will not form and the gingiva will heal in about 3 days. It is better to prep the tooth well subgingivally to have a SSC that fits well than worrying about gingival pockets..."it will heal".

SSC is really a skill development. The operator has to look at the unpreped tooth and to imagine what kind of preparation has to be done in order for the tooh to fit that crown. So, look, think then prep. rc 109

When seating a SSC, it should be seated lingual to buccal, and snap the crown over the buccal. In addition, the head should be supported for maxillary SSC, and the jaw for mandibular SSC.

TO get the best results in placement of SCC, make sure you go subgingival and make sure you select a close size of SCC to fit the crown.

Unknown said...

SSC are cost effective; they are great for the life of the tooth, take little time to prep and have a significantly lower failure rate than Class II Ag restorations (a particular study compared lower distal primary Class II lesions that had a 70% failure rate in 2 years to SSC with failure rate near 0%)

For SSC crowns you want to make the tooth fit the crown. Also the buccal cervical bulge will not help to retain the crown and should be removed for a better fit.

When more than two surfaces of a tooth need to be restored, a SSC is the best restoration for primary teeth. Fuji 1 is the cement of choice for SSC cementation.

Due to the high failure rate of MOD restorations in children, choose a SSC restoration instead. Prepare the tooth on all surfaces fitting the m/d dimension of the tooth to the closest 3M ion preformed crown. Seat the crown to 1-1.5mm below the gingiva.

Adequate preparation of primary molars--reduction of the buccal and lingual bulges--is important for SSC restorations. SSCs are usually cemented using Fuji 1 and seated lingual to buccal.

If you place a SSC in hypo-occlusion in a pediatric patient, the crown will be in occlusion in a week. Never leave a crown in hyper-occlusion.

In the crown prep is better to use a tapered course diamond for no ledge and better retention.

It is seen that buccal bulges do not increase crown retention. It may actually lead to crown overhangs, gingival irritation and increased failure.

When primary molars require restoration, it is best to fit the prep to the crown - specifically a SSC. It is better to do this with a pediatric patient because it is more cost and time effective - you want to minimize the time that a pediatric patient is seated in the dental chair. Also, it is very important to remove the lingual and buccal cervical bulges, and the crown must be seated from lingual to buccal.

In order for SSC to be effective, there should an extension of 1.5mm into the sulcus. Blanching is typically seen from this.
SSC are prepared by shaping the tooth to the crown, not crown to the tooth (as in permanent dentition).
