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.
Emmy Le #142
Fuji I cement is strong enough to retent the SSC. After determining the mesio-distal dimension, we should make the tooth fit the crown.
Eric Cheung #110
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).
Dilshad Abtin #524
Ion Nickel SC are very difficult to contour with pliers and also we don't need to trim them.
Heidi Gonzalez # 526
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.
Sanaz Hamzehpour 132
There is no scientific evidence that maintianing the buccal bulge will increase crown retention. So ahead and prep.
Liz Miltner #150
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.
Tina Duong #125
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.
Jun Flores 130
Natalie Nguyen #159:
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.
Austin Tung 187
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.
Claudia Rodriguez #531
Removing the buccal bulge in a SCC prep does not compromise retention. Also, use Fuji 1 to cement the crown .
Kim Pham #167
When preparing two adjacent teeth for SSCs, it is necessary to leave at least 1.5mm of space between the teeth.
Orly Hendizadeh #134
SSC's should be prepped to a feather edge with the occlusal, interproximal, and buccal bulge removed. Select the crown based on MD dimension and seat from lingual to buccal.
Broc Mushet #156
The buccal bulge should be removed in a SS crown prep and the SCC should be seated lingual to buccal.
Sydon Arroyo #102
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.
poonam rai#530
Jonathan Do #121
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.
Sonia Lee #145
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.
Tiffany Hsu #529
SSC should be seated from lingual to buccal.
Hoang #135
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.
J.Oka 162
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.
Paredes #164
In preparing adjacent crowns for SSC purposes you need to increase the interproximal reduction distance so that the space between the two teeth is 1.5mm
- Neilesh Patel (Neil Patel)
#165
M-D of the primary tooth should be consider to fit the pre-fabricated SSC and buccal and lingual bulge should be reduce to obtain the best fitting possible.
Soheil Yashari #191
SSC should be the treatment of choice in many cases. Not only do they cost less than other restorations but they also take less time to put on. They are just as effective as other restorations as well.
-Carol Kim (138)
When prepping tooth for SSC, select the correct size pre-formed crown, remove the buccal bulge and prep the tooth to fit, then cement with Fuji I.
[Colby Smith #178]
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.
Bozhena Fisher #128
Indications for anterior crowns include fractures, pulp involvement, subgingivial decay, and large proximal lesions.
Shelton Chow #111
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.
Stacy Yu #193
Make the crown prep fit the crown, not the crown to fit the prep. SSC can and should be prepped and restored quicker than most think.
Ryan Plewe
#168
Extend prep of SSC 1-1.5mm subgingivally. If space has been lost a maxillary SSC can be used to fit a mandibular primary molar.

Joshua Cardwell #108
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.
Shelby Padua #166
Michelle Duong #123
SCC should be placed when restoring a primary tooth with 2 or more restorative surfaces.
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
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".
Jared Martin #147
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.
Shannon Lazarian
#133
I found the part about the open faces SS crowns the most interesting as a more esthetic option for the patient.
Marc Thomas #182
SCC is recommended for teeth that need 3+ surfaces prepared, reduce in all dimensions like for normal crown prep, keeping B bulge will not help retention, therefore, ok to remove.
Alina Tiraspolskaya (#183)
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.
Naomi Nguyen, #158
Prep B and L for better retention and Nickle ion crowns are in favor since it is precontoured.
Karen Li #146
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
Trish Barsanti #105
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.
Cornel Crasnean #525
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.

Sanam Soroudi #180 (oops forgot to incude my name)
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.
Kevin Omoto #163
When prepping a tooth for a SSC, retaining the buccal bulge will not increase crown retention.
Joanne Kim #140
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.
Amy Dixon #120
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".
Raquel Ulma #188
When preparing a SSC for a pediatric patient, The most important thing to remember is that you prep the tooth to fit the crown.
Rick Shamo #176
I was surprised when Dr. Troutman said a SSC has almost a 0% failure rate if done correctly!
Morris Poole #169
SCC are used preferentially over composite or amalgam when >2 surfaces involved in a restoration.
Choose the crown based on the MD dimension.
Fugi I is a good cement for SCC.
Chris Claus #113
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.
Matthew Moadel, Student #151
While preparing teeth for stainless steel crowns,it is better to leave a rough/coarse surface as it increases surface area and aids in retention.
Amandeep Iqbal
#527
When 2 or more surfaces in primary teeth are involved, the ideal treatment would be placing a 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.
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%)
Jeanne Wong #195
1-1.5 mm of subgingival reduction is needed for preparation of an SSC. The SSC is chosen based on the mesial-distal dimension and seated from lingual to buccal.
Amy Tran #184
SSC should be used when decay is present on 3 or more surfaces. Prefabricated crowns should be chosen according to their correct MD dimension.
Robert Busan #107
Primary molars with more than 2 surfaces to be restored should receive a full coverage crown. Keeping the buccal cervical bulge does NOT increase retention and should be reduced.
Dan Nelson #157
stainless steel crowns should always be seated lingual to buccal,1.5 mm of interproximal space is needed to seat ssc. Unlike in permanant dentition,in primary teeth you must prep the tooth to fit the crown.
Hamid #174
In order for crowns to seat properly always get rid of gingival ledge, proximal contacts and buccal cervical bulge. Always support jaw when seating mand crowns and seat from ling to buccal.
Edvin, #100
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.
Cynthia Morford #153
SSC crowns, if done properly, have a great success rate as compared to composite or amalgam restorations. However, much care must be taken to correctly prepare teeth for SSC or else they're more prone to failure.
Nicholas Quach #170
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.
Diana Craft
#115
3m ion crowns are different from unitek crowns in that they are precrimped and precontoured. Fuji 1 used to cement stainless steel crown.
Parham Saghizadeh #171
I was surprised to learn that a stainless steel crown was usually preferable to a Class II restoration in most cases. Fortunately, developments in pre-fabricated crowns make crimping almost obsolete.
Will Traynor #186
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.
Christine Chung #112
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.
Jared Lee #143
The faillure of SSC can be 0 if they are made correctly.
In the crown prep is better to use a tapered course diamond for no ledge and better retention.
1. SSC is better than MOD amalgam restoration
2. when do SSC prep,bucal and lingual surface should be prep too
3.2-3 mm open bite after SSC cementation post no problem to pedo pt's dentition, a big surprise to me.
Lei Zeng, #535
Pedram Sooferi 179
SCC is a good way of restoring the tooth,extensive restorations are less reliable than SCC so use it often.
It is seen that buccal bulges do not increase crown retention. It may actually lead to crown overhangs, gingival irritation and increased failure.
-Dave Tajima
#181
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.
SCC preparations should include a reduction of the buccal bulge...if this step is not followed the retention of the restoration is greatly compromised
SSC can be a very profitable procedure if done efficiently.

Niki Zarabian #194
SSCrowns can work on anterior teeth, but are not esthetically pleasing. However, you can cut off the buccal portion or buy prefabed crowns with porcelain baked on.
Jake Cragun
#117
The main reason for SSC failure is due to incomplete clean-up after cementation.
Sujain Dissanayake #119
In teeth with more than 2 carious surfaces the placement of SCC is recommended. Unlike crowns in adults, here the tooth is prepped to fit the crown.
Varo Boyajyan #106
Wow, I can't believe I forgot to post again! darn...Anyways, the thing that I thought was most important about the lecture was the statement that stainless steel crowns can have a 100% success rate if done correctly....
Sean Nguyen #160
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).
Ernest Lai #141
-SSC's are cemented with Fuji I cement. Seat the crown lingual to buccal, then make sure that the marginal ridges are even, and then have the child bite into occlusion to make sure the crown seats.
