Custom abutments alone will not eliminate the clinical effects of poor cementation techniques around dental implants

With proper planning, placement, prosthetic treatment, and maintenance, dental implants have been shown to be a predictable and reliable treatment option with a high success rate. Clinicians who place cement-retained implant restorations, however, should be aware of the potential and sometimes irreversible biological complications associated with residual excess cement and should be prepared to consider using different practices that may reduce the problem. The present case reports describe the use of custom abutments to restore deeply placed implants with the intent of minimizing residual excess cement.
