PET for Multirooted Teeth

  • Chapter
  • First Online:
Partial Extraction Therapy in Implant Dentistry

Abstract

The immense success in achieving excellent soft tissue contours around implants placed in the esthetic zone with the PET procedures has opened up the possibility of performing it on multirooted teeth. However, the presence of two or more roots adds to the complexity of the case and special attention is needed to achieve consistent results. In this chapter, the authors share their clinical experiences and describe the step-by-step procedure of performing socket shield procedures in premolars and molars. Case selection and risk factors are explained to prevent complications and failures.
