Full-Coverage Restoration in Relation to the Gingival Sulcus
You will receive 1 credit(s) of continuing education credit upon successful completion of this course. The purchase price of this course is $41.00
This course discusses scientific evidence regarding the full-coverage restoration (FCR) margin placement and periodontal health.
Upon completion of this course, participants should be able to do the following:
- Discuss the literature related to full coverage restoration and its effect on the periodontium.
- Describe the clinical circumstances requiring an intracrevicular full coverage restoration.
- Define the indications and contraindications for intracrevicular full coverage restoration.
- Discuss the procedure for FCR.
The full-coverage restoration (FCR) and its effect on the periodontium have been controversial over the last half-century. This conflict relates to whether the margin of the FCR should be placed at or above the gingival crest, or into the gingival crevice. Clinicians and researchers alike have focused their attention primarily on the mechanistic aspects of fixed prosthetic design (i.e., marginal configuration and fit). Although marginal quality and form are factors in the fabrication of the FCR, they alone will not determine periodontal health and restorative success. What determines the success of the FCR is its ability to restore form and function to the masticatory system, without adversely affecting its biology. Each technical phase of treatment (i.e., tooth preparation, impression-taking, the provisional restoration, and the final restoration) must be performed within the limits of biologic adaptation. The literature review in this course discusses the scientific evidence regarding FCR margin placement and periodontal health.
