Episode 156 hosts Professor Bob Khanna, a dental surgeon and expert facial aesthetic educator from Reading in the UK. Professor Khanna was the world's first recognised dentist to offer injectables and since 1996, he’s been a leading thought leader in the field. He's continually evolved his own novel techniques and modalities to treat the face holistically.  He is also a global-thought leader in the diagnosis and management of teeth grinding and clenching problems, also known as ‘bruxism’.  Injectors very commonly treat the masseters for both aesthetic and teeth grinding and so we ask the question - should they be doing this and what problems might they inadvertently create without a thorough examination? We discuss: - What bruxism is and how grinding differs from clenching?  - Why these issues occur?  - The role of posture in preventing parafunctional habits - The problem with soft dental plates that are commonly made by dentists to protect the teeth - How bruxism contributes to 'TMJ' (jaw joint) disorders - The forces that are generated between the teeth when grinding - What happens in bruxism exactly and what are the consequences of it?  - How dentists identify bruxers: key bullet points when examining the face and mouth    - Why most dentists aren't experts in treating and assessing bruxism symptoms - What injectors should ask and do when assessing their patients - The anatomy of the muscles of mastication, as well as some of the accessory muscles involved in bruxism - The role of botulinum toxin to treat the muscles of mastication - the risks of overtreating the masseters: physiological and aesthetic - how to approach the masseter - How to approach the temporalis - how to approach the lateral and medial ptyergoids - how to decide if these muscles are impacted or need treating in bruxism? - how injectors can work alongside dentists in managing bruxism symptoms   Show your support for IA via Patreon Follow IA on Instagram Visit our website  Subscribe to IA on Apple Podcasts Subscribe to IA on Spotify Contact Dr Jake & David  More about Dr Jake Follow Dr Jake on Instagram  Follow David on Instagram  Follow Professor Khanna on Instagram: www.instagram.com/bob_khanna
