5 (4 votes)

CE Hours: 1.5

Description: Choosing to save and maintain teeth can be a difficult decision to make when it comes to compromised tooth structure. For example, periodontal procedures can be helpful to lengthen clinical crowns or to gain access to root surface defects such as external root resorption. However, before considering periodontal procedures, there are several factors to consider: Esthetics, tooth anatomy, alternative procedures, and long-term prognosis should all be taken into consideration. This presentation will review perio-restorative concepts to consider for endodontics as well as dive into the limitations that determine the restorability of teeth. The focus of this presentation will be on crown lengthening and oral plastic surgery procedures.

Learning Objectives: 

  • Discuss the indications, limitations, and technique for crown lengthening procedures
  • Discuss the indications, limitations, and technique for various oral plastic surgery procedures to address root surface defects such as external root resorption
  • Review periodontal considerations in determining the prognosis of teeth and how they may affect endodontic care
