speaker – Tom Bereznicki

Tom Bereznicki

Tom graduated from Edinburgh in 1976, moved to London and worked at Guy’s and The Royal Dental Hospitals before entering general dental practice in 1978. In 1982, he opened his own private practice as a ‘squat’ in Queensgate before moving himself and his patients to join Dawood & Tanner in January 2011. His Special Interests lie in all aspects of Restorative Dentistry but in particular Occlusion and Emergence Profile.

In October 2013 Tom was appointed as an Honorary Clinical Teacher one day a week in the Department of Primary Dental Care (PDC) at King’s College Hospital, Denmark Hill, and started teaching in January 2014. In January 2017, he was appointed as a Regional speaker to The British Academy of Cosmetic Dentistry on the subject of Occlusion. In March 2017 he was co-opted to The Advisory Board in Primary Dental Care at The Royal College of Surgeons Edinburgh. In June 2017 he was appointed as Extra-curricular Education Co-ordination Officer in the King’s College London Dental Institute Students Society. In July 2017 he also joined the Steering Group of The Faculty of Dental Trainers at The Royal College of Surgeons Edinburgh.

More recently, Tom has been appointed as a Member of the Clinical Board of Tooth Wise, a new-media/technology company delivering news and resource to those involved in dentistry.  In the FMC Dental Industry Awards, the company won ‘The Best Use of Facebook’ Award 2016 and was The Finalist in ‘The App of The Year’ Award 2016.

In March 2018 he became a Member of The Faculty of Dental Trainers at The Royal College of Surgeons, Edinburgh (MDTFEd). In April 2018, he became Staff President of The Kings Students Dental Society.

Originally he lectured on The Creation and Duplication of Emergence Profile but now primarily lectures on Restorative Aspects of Occlusion at postgraduate level. He also lectures at undergraduate level on a variety of topics in Restorative Dentistry as well as mentoring younger dentists in their careers. He has had articles published both here in the UK and in The States.

regional – Occlusion for long-term, predictable cosmetic dentistry

Occlusion for long-term, predictable cosmetic dentistry


Our patient’s acceptance of dental treatment depends to a major extent upon their perception of the final appearance. However, as well as delivering beautiful results, it is incumbent upon us as clinicians to ensure our work stands the test of time.

A long-term protocol to both deliver and more importantly maintain a healthy occlusal pattern is arguably more important than ever given the nature of today’s comprehensive restorative treatment plans. Yet should breakages occur the usual cry is that the occlusion has not been correctly dealt with by the clinician.

However, given the various occlusal philosophies currently available, it’s perhaps not surprising that many clinicians are confused, and consequently daunted about offering the treatment many of their patients desperately need. The very real problem for today’s clinicians is how to convert the “nuts and bolts” of the various occlusal theories into a workable occlusal practice.

Most Occlusal theories are based upon establishing a repeatable and consistent hinge Axis; commonly described as “Centric Relation”, yet for many clinicians the recording of CR remains a major stumbling block. The de-programming device described by Dr John Kois of Seattle seeks to remove the confusion and simplify the entire process, thus making the achieving and recording of CR a more predictable prospect altogether. However, recording CR is just the starting point, and we need to be able to move forward from this base line position and deliver actual treatment.

Based upon the teachings of Dr John Kois, a logical step by step process will be outlined enabling the general dentist to approach the often confusing world of occlusion with greater confidence. Ken Harris is the leading exponent of the Kois occlusal philosophy here in the UK, and the aim of this presentation is to describe in great detail, with reference to actual treated cases, the streamlined yet workable approach to Occlusion, from assessment to completion, he uses on a daily basis.

Learning outcomes

At the end of the presentation the delegates will be able to:

  1. confidently record an accurate Centric Relation (CR) position using the Kois deprogrammer and mount study models using the Kois dento-facial analyser
  2. diagnose the 5 occlusal conditions as classified by Dr John Kois, and manage the occlusal risk each presents
  3. appreciate the relevance of Envelope of Function when considering Anterior Guidance
  4. accept that Restorative Material selection cannot overcome improper occlusal management
  5. deliver a complex restorative treatment plan in stages, utilising a logical and comprehensive, step by step protocol based upon the teaching of Dr John Kois
