Bilaminar technique in the treatment of a deep cervical abrasion defect

Int J Periodontics Restorative Dent. 2008 Feb;28(1):63-71.


New materials (restorative and adhesive) for the treatment of cervical abrasions have produced better results in terms of esthetics (choice and stability of colors) and duration (marginal fit and wear resistance). Nevertheless, conservative restoration of cervical abrasion cannot be considered the most suitable treatment in certain clinical situations: (1) when the abrasion defect involves the root surface, either exclusively or primarily; (2) when a site has difficult esthetic demands resulting from excessive tooth length with gingival recession; and (3) in the presence of root caries. The aim of this case report is to describe the application of the bilaminar technique to treat a deep cervical abrasion associated with a recession-type defect. The bilaminar surgical approach shown here consisted of a connective tissue graft covered by a coronally advanced pedicle flap. The connective tissue graft was placed inside the root concavity to compensate the abrasion space and to prevent soft tissue flap collapse internally. The graft, by acting as a "biologic filler" or space maintainer inside the concave abrasion area, stabilized the covering flap and helped restore a correct tooth emergence profile.
