SP-38 Treatment Strategies of Apical Periodontitis in Teeth Adjacent to Dental Implants

Product not yet rated

CE Hours: 0.75

Description: Apical periodontitis (AP) in a natural tooth may jeopardize the health of adjacent dental implants, potentially leading to retrograde peri-implantitis (RPI). Both conditions arise from bacterial infections, underscoring the importance of effectively managing AP to prevent implant-related complications. This presentation explores treatment strategies for teeth with AP near implants, emphasizing infection control and RPI prevention through clinical case examples. A key approach involves performing endodontic microsurgery on the affected tooth while simultaneously placing the adjacent implant. This combined technique minimizes surgical interventions, reduces overall treatment time, and lessens patient trauma while effectively preventing RPI. In cases where RPI does develop, timely intervention - whether surgical or non-surgical root canal treatment, with or without implant apical surgery - can restore periapical health in both the natural tooth and the implant.

Learning Objectives:  

  • Discuss the shared etiology and pathogenesis of apical periodontitis (AP) and retrograde peri-implantitis (RPI).
  • Discuss the strategies to minimize the risk of RPI in implants adjacent to teeth affected by AP.
  • Discuss treatment approaches for managing RPI in implants near AP-affected teeth.
