Abstract
|
|
|
|
When the marginal fit of fixed dental prosthesis decreases, biological and technical complications, such as plaque accumulation, periodontal disease, hypersensitivity, components fracture, cement loss, can happen. The complications affect the long-term success and survival of prostheses. This case report describes a clinical procedure to minimize the marginal gap of implant-supported screw-and-cement retained prosthesis by removing prosthesis-abutment complex and burnishing the interface area. The marginal gap was measured before and after the burnishing using a stereomicroscope and compared. This technique improves the marginal fit, thereby contributing the longevity of the prosthesis.
