Couple Challenge Hers
Posted by eric in Uncategorized on July 28th, 2010
This tai tai is unhappy about her 2 central incisors and wants to straighten them without braces. Her expectations are reasonable, but this is still a challenging case. We try not to overtreat and at the same time we can’t do so little that there is no significant improvement. We have indicated root canal and emax crowns. Stay tuned for updates.

This bridegroom to be is understandably anxious about his wedding photoshoot in a few months’ time.
Those of you who have been following our fan page should know roughly what Dr Chan has in mind.
Another Extreme Makeover
Posted by eric in Uncategorized on July 27th, 2010
This young lady from China wants her teeth straightened fast and without braces. It’s with some trepidation that we decided to take on this challenging case. So far, things have been going well.
You don’t need to be a dentist to tell that this is a challenging case. We marked her 2 canines for extraction. We’ll also need to do some gum surgery on her laterals. Her incisors on the left side will also need to be “moved” to close the gap after the canine has been extracted.
Another look at how difficult this case is. Apart from extractions and gum surgery, we also need to do root canal on the incisors on the left side.
Extraction just done on the right side. There is hardly any gap between the lateral and the first premolar. This will be the easy side.
The other canine has also been extracted. Gum surgery done, exposing more crown height for the lateral incisors and the premolars. The gap on the right side is more significant.
Here’s the patient’s left side. There is a gap about half a tooth wide. We have already done root canal on the left incisors. We will later cut them off and rebuild with post crowns to close the gap.
4th day after surgery. Check out the healing.
The teeth have been trimmed down and temporary plastic crowns placed.
We will wait 2 months for the gums to stabilise, then we’ll place emax crowns over them.
Emax crowns fitted.
Case completed.
It’s In The Gum
Posted by eric in Uncategorized on July 27th, 2010
This patient complained about her crooked front teeth spoiling her smile, but on closer examination, the crookedness is not so bad. Her main problem lies with the gum line. She shows too much gums when she smiles. We recommended gum surgery as a first step to improve her smile.
The patient shows a bit too much gum when she smiles. Her teeth also look squarish and do not suit the shape of her face.
We can tell that her teeth are not fully exposed. Quite a bit of her pearly whites lie beneath the gums.
Crown lengthening surgery exposes the covered teeth.
This is her new smile and gum line immediately after surgery
We’ll wait 2 months for the gums to stabilise before we make her veneers.
We removed her stitches one week later. See how quickly her gums healed. Her teeth don’t look “concealed” anymore.
This is what it looks like after 2 months. We prepared her 2 front teeth for veneers and did some microabrasion on the other teeth to remove hypoplastic “stains”
And here are the bonded veneers with some microabrasion on the lateral incisors and canines.
Painless Injection?
Posted by admin in Uncategorized on July 27th, 2010

The Quicksleeper is a system that claims to give pain-free injections by delivering anaesthetic directly (and deeply) into the spongy bone around the teeth to be numbed. The folks who developed this system go on to say that numbness is very focussed and will not affect lips, tongue and other soft tissues that do not need to be numbed.
Some of the reviewers claim that there is no nerve endings in bone - someting patently untrue. And I certainly can’t see how a needle can be inserted deep into bone (obviously having first passed through the mucosa) can cause no pain. Unless of course, the needle is inserted mm by mm with tiny drops of lignocaine injected with every mm. If that’s the case, how long will it take to inject? I doubt the Quicksleeper suppliers’ claim that it saves time is true.

Most dentists who do not have deep pockets employ a slow, deepening injection technique. First is surface or topical anaesthesia, followed by a few drops in the mucosa. When the mucosa is adequately anaesthesised, the bulk of the anaesthesia is then delivered - often with no pain at all. The very slight pain experienced when the mucosa is first injected (for just one second) is tolerable to 99% of my patients. For those who can’t tolerate that, they probably won’t tolerate drilling, yanking and other movements involved in the dental procedure.
IV sedation solves the problem.
I find it curious that so far, almost all the information we can get from internet are sponsored reviews. One practice that boasts that it owns such a machine makes a telling statement that it’s not suitable for all patients but did not elaborate.
The price tag? US$6000
More Emax
Posted by eric in Uncategorized on July 24th, 2010
This middle aged lady had a couple of discoloured and root canal treated front teeth. She wanted the aesthetics to be improved.
2 discoloured teeth. Alignment is also slightly off.
Emax crowns tried in the mouth. Colour and alignment have been corrected.
Emax crowns cemented.
Time to do scaling and a new denture for her back teeth.
Crouching Tiger Hidden Dragon
Posted by eric in Uncategorized on July 23rd, 2010
A young and attractive childcare teacher cum part-time model turned up at our clinic with an interesting problem. Her main complaint was tilted right incisor. She could not put on braces as it would affect her modelling assignments.
Apart from a tilted incisor on the right side, she also has a retained baby tooth in the canine position.
The tilted tooth affects her smile very significant.
An xray solves the mystery. The patient’s permanent canine decided to lodge itself in the upper jaw bone directly above the right incisor. The “hidden dragon” pushed the root of the incisor backwards (palatally), tilting the crown of the same tooth forward (labially).

The “hidden dragon” was surgically removed and the defect was filled with bone graft.
The patient was pain free from the second day after surgery. We proceeded to do a root canal on the tilted tooth.
Here’s the tooth with fibre post and composite core built up.
Shade matching was a challenge. We didn’t want to follow the colour of her other teeth too closely as she may want to do something about the unsightly spots soon.
She may also wish to extract her baby tooth and replace it with an implant.
And here is the temporary crown.
Stay tuned to see our emax crown when it’s ready.
Emax For An Actress
Posted by eric in Uncategorized on July 23rd, 2010
This young actress chipped her front tooth. Even though there was no nerve exposure, she decided to do root canal treatment followed by an emax crown. We explained the options to her. Both bonding and veneers will increase the bulk of the tooth and make it look even more protruding. By doing root canal, cutting back the tooth and then rebuilding it, we can effectively reposition the tooth and make it look straight.
The right central incisor looks short because it is protruding. it is also chipped at the corner.
The lateral incisor was a little instanding. As the patient has budget constraints. We did a little bonding to bring out the lateral incisor. Root canal is done on the protruding incisor.
Another view. The left central incisor was also bondedso that all 3 teeth will look harmonised when the protruding tooth is crowned.
An emax crown has been fitted. Check the alignment.
She’ll look even better if the 2 adjacent teeth are laminated with Empress veneers. bonding has its limitations.
As the finishing for the emax and bonding can be quite different, the patient is advised to have veneers on her other 2 teeth.
Changing His Smile
Posted by eric in Uncategorized on July 23rd, 2010
This senior executive has been neglecting his teeth for ages. Then, his front tooth broke and he only complained about the discomfort and not the appearance.
We’ve decided to make a veneer for him.
Very minimal preparation or trimming of the tooth was done. A rubber impression was taken and sent to the lab for an Empress veneer.
Veneer was cemented. Bulk has been added to that tooth and it could have been better if he had done more veneers. But then, he only complained of discomfort and couldn’t even be bothered if we got the colour right.
We decided that he needed a scaling to clean out his lower teeth and did it for him.
Here he is after scaling. For the first time, we saw him looking at his teeth in the mirror for more than a second.
Ceramic Bridge
Posted by eric in Uncategorized on July 23rd, 2010
This young gentleman has lost his front tooth in an accident a few years ago. His other front tooth was badly chipped. Root canal and crowning were done on that tooth. He was comfortable with his dentures, but decided to do something more sophisticated. We removed his old crown and used it, along with the lateral incisor, to support a full ceramic bridge.
Old crown removed, lateral incisor trimmed down.
We were fortunate that gold was used to build up the core of the old crown. The colour of the precious metal blends in well with full ceramics.
The full ceramic (emax) bridge tried in the mouth. The translucency of the material gives it a more natural look.
Bridge is cemented.
