Cement-retained restorations, overview

Key points

  • Cement-retained restorations are a traditional design option allowing for passive fit
  • Offers advantages especially in the esthetic zone, as abutment screw channel opening does not affect esthetic bridge design
  • Subgingival cement is a main reason for peri-implant tissue inflammation, meticulous removal of cement excess is crucial for peri-implant tissue health
  • Today, CAD/CAM scanning and milling of the restoration provides high precision and passive fit
  • To avoid potential complications related to cementation procedures, especially in edentulous situations a screw-retained CAD/CAM fabricated construction is nowadays the option of choice

Inflammation and infection

Inflammation can be limited to the soft tissue around the implant (mucositis) or involve the underlying bone tissue as well (peri-implantitis). Infection can be caused by various risk factors, such as inadequate hygiene and patient compliance...
