PPD Magazine Editorial – Mark Cronshaw

August 26, 2011 Leave a comment

I really enjoyed reading Mark Cronshaw’s editorial piece in PPD magazine so I asked him to send me the text so we could repeat it here. Well worth a read.

Fractured teeth and restorations, sensitivity and acute pain, loose teeth, abnormal wear, bone loss. Difficulty chewing, atypical facial pain, TMJ breakdown and the list goes on. There are those (including myself) who believe this condition is directly related to frequent headaches, neck and shoulder pain, tinnitus, vertigo and more. An impressive list of important disorders – and the likely cause of these many problems is…? Of course the answer is occlusion. Read more…

Abfraction lesion under gingival tissue – final proof?

August 25, 2011 2 comments




 Loss of cervical tissue around teeth has been linked to the presence of excessive occlusal loading.

These are known as abfraction lesions, defined as “Loss of tooth structure, usually in a wedge-shaped pattern in the cervical area of the tooth, attributed to flexure and fatigue in an area away from the point of loading (usually cervical).” The true aetiology of these has been called into question, with some recent research purporting to show that a toothbrush and abrasive dentifrice are required for them to develop. 

A case I saw this week seems to contradict such an assertion – this aesthetic case need a little gingival recontouring around the anteriors:

…. so I started to work on the lateral first and look what has appeared! This photo was taken moments after removing the gingival tissue, and it hasn’t been touched by a bur: 

Now, this looks suspiciously like an abfraction lesion to me, and it has has been subjected to significant occlusal loading palatally from a deep overbite Class II div 2 situation for many years. Is this final proof that such things really do exist – it can’t possibly be toothbrush abrasion since this is the first time it’s ever seen the light of day. Any other ideas, or do you think I have found something significant?

Survey on oral and dental considerations with eating disorders

August 25, 2011 Leave a comment

I think we’re all aware that bulimia in particular can be a major factor in the development of occlusal changes and wear, so I’d be very grateful if members of the dental team could complete this survey on oral and dental considerations with eating disorders for a project being organised by Alexandra Day (Sheffield) with support from Dr N Martin (Sheffield), Dr A Milosevic (Liverpool) and Prof A Eder (UCL Eastman).

Should take no more than a few minutes and will help highlight possible need for better support and education in this increasingly important field.

Many thanks.

More from Barry Glassman on Bruxism Awareness Week

August 12, 2011 3 comments

Dr. Barry Glassman, internationally acknowledged as a leading authority on TMD, migraine and dental related sleep breathing dysfunction, will open the 2nd Bruxism Awareness Week with a lecture at the Royal College of Physicians in London on October 24th 2011.

It turns out that Dr Glassman’s interest in the field was first encouraged by attending a Niles Guichet course, just like the majority of lecturers for SDS Occlusion! Interviewed at his specialist clinic in Pennsylvania, Dr. Glassman described how his interest was first aroused in this specific aspect of dentistry.

Feedback from the POISE Course

August 10, 2011 Leave a comment

We get great feedback from our courses, and it’s great to hear how we are changing lives, but here is one that I felt we had to share with you:

I’m amazed what a difference having extra knowledge of occlusion has made. I have treated many hundreds of patients since finishing the course but one in particular jumped out at me. The patient in question has had undiagnosed occlusal problems for years. The SDS questionnaire flagged up the problem. Past dental history revealed a bridge which had failed four times in ten years and numerous broken teeth. On examination he has very large bony exostosis, abfractions, Masseteric hypertorphy and classic violin strings through his Temporalis which were excrutiating to touch. Absolute barn door case, straight out of the notes. Amazingly he’s been a patient at the practice for 20 years and it had never been picked up. As you said on the course, you can only see what you know. After a stabilization splint and a decent bridge made in CR he’s got no pain and is pleased as punch with me as a dentist. He is a GMP for a living and values the holistic approach that we’ve taken to his treatment. He has since recommended other patients to the practice.

It frustrates me that there is such a big black whole in undergraduate occlusion teaching. I now don’t like looking at work that I’ve done before the course as I can see my own mistakes even though I considered myself a good dentist. I have older dentists who’ve been qualified for years telling me that occlusion is a waste of time. I truly believe it is not and am very grateful to you and Higgy for changing my career. CM

If you’d like to change your career in a similar way please book on our next POISE course, 12th/13th November 2012 at ACE in Wakefield, you won’t regret it! Call Jemma on 01457 821800 or email:
