Introduction to Implantology Manoj S Parmar BDS, MFDS, MJDF, MSc (impl), PGCert(rest), PGCert (MedEd) Aims 1. Enable you to confidently introduce dental implants to your practice 1. Establish a study-club for your continued learning Objectives 1. Why implants should form an integral part of your practice 2. Anatomy of an implant and its components Teeth vs Implants Implants must not be regarded as replacements for teeth but a means to restore edentulous spaces Why introduce to your practice? 1. Predictable form of treatment 2. Develop range of services offered to patients 3. Medico-legal obligation 4. Keep treatment in-house 5. Additional income stream 6. Stimulate further learning 7. Increasing patient demand 8. Unlikely that a substitute will developed in next 10yrs Concerns 1. Many dentists placing implants 2. Limited experience as dentist 3. Corporate run weekend courses 4. No mentoring 5. Lack of evidence based learning 6. Poor planning 7. Poor basic surgical knowledge 8. Need a toolbox of techniques Complications The ideal implantologist… …needs to be a prosthodontist with the surgical expertise of an oral surgeon and the finesse of a periodontist Introduction to implants copyright manoj parmar 30july2016 handout - 30 July 2016 Copyright 2017 Acorn Dental
