Treatment guidelines

Cement-retained restorations, esthetic zone

Key points

  • The practitioner may chose to cement retain the final restoration.
  • The choice cement final restorations mirrors conventional prosthodontics.
  • There are multiple abutment choices for cement retention.
  • The practitioner must decide to use a provisional or permanently cement the restoration.

Chandur Wadhwani: Implants, cement and peri-implantitis - science and the missing link

Cementation procedures and materials have been reported to cause complications in implant prosthetics, mainly inflammation around the implant due to cement material excess. Cementation procedures are a complex system, not all the dimensions of which seem to be fully understood and...

Chandur Wadhwani: The impact of cement, its techniques and protocols for long term outcomes

Residual cement is considered a main causal risk factor for peri-implant disease. Cement remnants causing microbial activity, immune reaction, allergic response, activation of titanium surface may be the route by which bone is lost around implants. Dr Wadhwani discusses the...

It is imperative that the peri-implant mucosa be inspected carefully to ensure no residual impression material is retained in the sulcus. Cementation of crowns on abutments can also result in cement being expressed and retained well below the mucosa. Great care needs to be exercised not to express cement apical to the crown being cemented.

In addition to cement selection, it is essential to employ a cementation technique that minimizes the potential for extrusion of excess cement into the peri-implant crowns with margins that are located deep below the mucosal margins, a common occurrence with dental implants.

When any restoration, provisional or definitive, is cemented over an abutment, the force of the expressed cement can displace the peri-implant mucosa and cement can be forced apical to the crown margin. Therefore, complete removal of all the excess cement is essential to prevent adverse peri-implant responses from the soft tissue or bone. Problems associated with residual cement left behind from incomplete cement removal were first reported in 1999. The potential post-cementation problems that can arise include bleeding, soreness, acute swelling, the presence of purulent exudate, and over time even radiographic evidence of actual bone loss.
