Learning from the past

Learning objectives:

  1. Original protocol
  2. Long-term result
  3. Minimal tissue violation

Abstract:

 A small piece of pure titanium has drastically changed the concept of treatment in modern dentistry not only from the viewpoint of clinical procedure but also from the research field.  A tremendous number of patients have been received the benefits of the implant treatment and they have been satisfied with the results.

 However, around the world, there are many reports regarding the problems of the implant treatment e.g. bone resorption, periimplantitis, sinusitis and fracture of component. It was not so common when we were following the original protocol previously. The convenience for dentists does not always correspond with the benefit of patients. It might be the results of violation against the Mother Nature such as the healing process and delicacy of tissue. We should focus on the scientifically demonstrated long-term results than the near-term results in the implant treatment.

 It is necessary to re-evaluate the original protocol established by Brånemark. I would like to discuss about some valuable tips in it and utilization of it in order to provide satisfaction for our patients over the years. The original protocol is never a fossil.
