Presented by: Andrew Dawood
Host: Zubair Sacranie
Date: 16 March 2021
Time: 19:00

As more and more patients are treated with an ever increasing range of dental implants, implant components, and treatment philosophies, every dentist will encounter implant failure in their practice. The use of a limited number of angled or short implants, and in extremely atrophic maxillae, the use of zygomatic implants is becoming widespread. Though such treatment has been shown to be predictable and generally trouble-free, failure can not only lead to loss of function, but there is also the potential to encounter a range of complications ranging from infection to mechanical issues which can have far-reaching consequences. Managing failure can be complex, therefore careful forethought is required to avoid complication and leave scope to salvage a compromised reconstruction.

Failure and complication will cause disruption and upset for the dentist and for the patient - who must be carefully counselled and consented. Treatment should be undertaken by well trained and skilled operators with the support of an experienced team

With more than 25 years' experience of working with implants and a spectrum of referring dentists, Andrew will reflect upon strategies for the predictable maintenance of reconstruction and tissue health, and the avoidance of short and long-term failure in full arch reconstruction.

This lecture will present practical approaches for the avoidance of failure and suggest various management strategies.


Learning objectives:

  • Outline how our patients should be informed and consented for full arch treatments
  • Describe some of the factors predisposing  for implant failure and prosthesis failure
  • Discuss component failure and retrieval
  • Present strategies for coping with failure in full arch reconstruction
  • Explain our  approach to maintenance for patients who have received full arch implant treatments


MRD RCS(Eng.) MSc BDS(Lon.)

Specialist in Periodontics and Prosthodontics

Andrew devotes his time to dental implant surgery at the Dawood and Tanner Specialist Dental Practice.  Research interests include implant design and manufacture, 3D technologies, and treatment planning and longevity in implant and restorative dentistry. Andrew is an Honorary Consultant at University College Hospital London where he provides implant based reconstructions for oncology patients.

Andrew carries out surgery for both referring colleagues and for patients of The Dawood and Tanner Practice. He utilises the latest technology to plan and implement both simple and advanced reconstructions, working closely with general dental practitioners and other specialists. He particularly enjoys the collaborative aspect of treatment, helping the general dental practitioner to bring the benefits of implant treatments to their patients and their working life.

Andrew has a particular interest in the implant rehabilitation of patients who have atrophic jaws; particularly those who have suffered implant failure or extensive bone loss.

Andrew has a passion for technology and ceramics, and is the Clinical Director of Cavendish Imaging, an independent CBCT imaging centre and medical modelling facility, and founder of  - a 3D printing studio. He is also a recreational potter.
