Orthodontics
He is the recipient of the first award for distinction in Orthodontics by British Orthodontic Society. International Functional Association bestowed an award to him in 2008 for his contributions to the field of Orthodontics. He published a textbook in 2002 called Twin Block Functional Therapy - Applications in Dentofacial Orthopaedics. Dr. Clark is credited to be the first person part of a teleconference at a dental course in Chicago in 1990 which was eventually transmitted to 25 different cities via satellite.
Twin-Block Appliance
Twin-block appliances are used to correct Class II malocclusions with a deficient mandible. The appliance is removable in nature and involves more patient compliance than fixed functional appliances such as Herbst, Forsus or MARA which are attached to teeth. As patient bites together, they bite with their mandible forward. Dr. Clark recommended the appliance to be worn for at least 1 year in order to see any growth changes happening. The actual growth of mandible is still a question and literature shows that a Twin-Block appliance is as effective as a Herbst appliance.
