Cement‐associated peri‐implantitis: a retrospective clinical observational study of fixed implant‐supported restorations using a methacrylate cement

Abstract

Excess cement left in the implant-mucosal interface caused bleeding on probing in most cases and suppuration in some. The removal of excess cement after cementation should be given high priority. In this retrospective observational study, an unusually high number of implants with excess cement after cementation was found with the methacrylate cement applied in the study.

Systematic review of some prosthetic risk factors for periimplantitis

“…Acrylate-containing dental restorations are considered to be susceptible to colonization by both bacteria and Candida. 10 The choice between screw-retained and cementretained prostheses should be based on the risk assessment for the individual patient, and care should be taken to avoid cement remnants when cemented restorations are preferred. The design of the prosthesis should facilitate proper maintenance.…”

Can Periimplantitis Be Treated?

“…Studies have shown that, in the presence of excess cement at the crown-abutment interface, periimplant mucosal inflammation or bone loss occurs 80% to 85% of the time. [57][58][59] The use of certain cement, for example, methacrylate-based cement, is associated with increased residual cement and consequently a higher prevalence for peri-implant diseases 57,60 because they are less viscous 60 and also more susceptible to bacterial invasion. 61 In contrast, zinc oxide eugenol-containing cements are more viscous, thus, easier to remove and can inhibit biofilm growth at the crown-abutment interface.…”

“…61 In contrast, zinc oxide eugenol-containing cements are more viscous, thus, easier to remove and can inhibit biofilm growth at the crown-abutment interface. 62 Customized abutments that bring the restorative margins coronally or screwretained restorations may be considered 57 if the restorative margins are located more subgingivally, 63 as it is technically more challenging to remove excess cement around such restorations. The ability to clean around the implant restoration plays a role in the development of peri-implant diseases.…”

Association Between Peri-Implant Diseases and Cement-Retained Prosthesis: A Review

“…Clinical and endoscopic signs of peri-implant disease were absent in 74% of the test implants after the removal of excess cement. Korsch et al 31 identified residual cement in 59.5% of implants. BOP was found at 80% of implants with residual cement and suppuration at 21.3% of the implants.…”
