In this 2 part series, Dr. Lars Laurell discusses the important concept of saving teeth in the periodontal patient. With the availability of dental implants, the concept of doing everything possible to save teeth has been reduced. The clinician is now in a position where they have to make a decision of whether to save teeth or extract and provide implants. Does periodontal treatment offer benefit to patients? At which point would a clinician need to consider extraction in periodontal patients? Which teeth can be saved and which teeth should be extracted? For the teeth that are extracted what risk factors need to be considered in providing suitable fixed prosthetic replacements? This lecture provides answers to many such questions, with examples of well documented clinical cases.
