Dear sammy. Most of the veterinary dentists offer either temporary crown extensions or inclined planes for those cases for which orthodontic movement is appropriate. If you have a particular case then I would suggest contacting your nearest specialist to discuss the case. Sending closed mouth photos with lips lifted can help with assessment. There are often several treatment options and it can very much depend on how committed the owners are to follow up treatment.

Certainly. Any of the "veterinary dentists" who pop up on these fora, and others too.

Opinions vary as to the pros and cons of each approach but one should offer both possibilities and proffer advice.

Yes – all right, I hold my hands up, I've been guilty of being misleading.

To rescue my ego, though, I plead thatI wasn't suggesting anyone should dismiss the damage, nor that deep penetration cannot happen, only that ever deeper penetration is not at all inevitable.

Even with the gross relative mandibular brachygnathism, closure is still limited by the occlusion of the upper and lower 9s, while the lower incisors generally induce little pits in the palate. Pressure is distributed between the six incisors and the canines so may never be great enough to cause inflammation or necrosis (the initial pit is due to tissue remodelling under pressure). Of course it may, and the periodontium of the upper canines is often damaged, so treatment is essential, none would dispute that. Interestingly, in mandibular brachygnathism, once the canines have been treated (be it by shortening or by orthodontic movement) the incisors are still impinging on the soft palate but we don't treat them and it's rare for serious damage to be the result there.

Whilst I agree that vital partial pulpectomy and direct pulp capping is frequently my treatment of choice - the comment that the impacting lower canine cannot penetrate the hard palate is erroneous.

This just happened to be a case from about a week ago. Because of the MAL2 there is no "incisor locking". The radiograph demonstrates the loss of radiodensity of the hard palate & a probe was able to pass int the nasal cavity

Another recent case:-

With no MAL2:- (Stills from an initial outing of my new loupe mounted video camera - so image not as good - still playing with white balance etc)

Shows the purulent material in the impact site - the depth of probe penetration and also the fishing out of necrotic bone fragment.

Another juicy one showing an unusual consequence....

So - please don't dismiss these impact damage lesions!

All the best

Bob

Very entertaining, and full marks for effort.

I hope it doesn't reach wide circulation to the doggy public.

I hate to be a spoilsport and a miserable old git.

But.

It contains several serious and significant errors and bits of misinformation.

Nobody in their right mind would suggest extracting the offending teeth. (Unless you are considering deciduous teeth, when nobody would consider anything other than extraction). Anybody who thinks that extracting a mandibular canine, especially in a young dog, is going to be a breeze and "not cost very much" is going to be painfully disillusioned sharpish. And of course it's completely unnecessary.

Shortening the tooth is a fairly quick and simple procedure and does NOT involve full root canal treatment – fortunately, since full root canal treatment would be a nightmare in a young dog. What it does involve is simply a vital pulpotomy and pulp capping. And it really does "not cost very much".

Finally: can we please bury the myth that the offending canine tooth will somehow work its way further and further in to the palate. The limit to closure in the dog's mouth is the occlusion of the upper 9 on the distal part of the lower 9, with almost simultaneously the occlusion of the incisal edges of the lower incisors on the cingula of the upper incisors.(the cingulum is that little step or platform at the back of the incisor). Once the jaws are closed, with those parts meeting, the tip of the canine cannot go further in. Once it has induced, by pressure, a little pit in the palatal tissues, there is no more pressure and it cannot go deeper. Of course there can sometimes be inflammation and maybe pain, and it often threatens the periodontal health of the upper canine which is a good reason in itself for taking some action.

Oh, and this malocclusion occurs in lots of breeds.

Still, I've learnt "Mandibula Augusta" .

It doesn't ring a bell with me and I don't think I've missed any dental threads in recent times... I'm intrigued why human dental students would be making a video on this.... Please do post a link if you manage to track it down!
