Histo-clinical evaluation of free
gingival grafts. Periodontics.
For example, Miller reported (100)% correlation between heavy smoking and failure to achieve complete root coverage using free
gingival grafts. (26) The often quoted study by Erley et al (27) demonstrated comparatively inferior outcomes in smokers treated with subepithelial connective tissue grafts for root coverage.
Among them guided tissue regeneration technique with free
gingival graft to treat such defect has recently been attempted with promising clinical and histological results (1,2).
The GTR technique has shown to be a viable alternative when compared to other root coverage techniques used for gingival recessions (free
gingival graft, repositioned flaps, and connective tissue grafts).
