Part 5: Mechanical Complications with Dental Implants

A large number of mechanical complications have been reported in the dental literature that could have been prevented through proper planning and design. This presentation will review the complications and discuss how to avoid unfavorable loading.


Learning Objectives:

Upon completion of this course, the participant should be able to:

  1. Identify the most common mechanical complications associated with dental implants.
  2. Understand the factors that create overloading of implants and prostheses.
  3. Understand the importance of implant placement in minimizing complications.
  4. Discuss the factors that affect implant loading.
  5. Know how to design single crowns and fixed partial dentures that resist adverse leverage when the implant positions cannot or are not ideal.


Several mechanical complications have been reported in the dental literature.  When  proper design guidelines are followed, many of these complications can be minimized or  avoided.  This presentation identifies the most common mechanical complications and  presents guidelines that help prevent adverse leverage on implants.  Additionally, when  implant placement cannot be ideal or the implants are not appropriately positioned, this  presentation describes methods that can be used to resist adverse leverage with both  implant single crowns and implant fixed partial dentures.
