The “palate-free option” for recession coverage
A 35 year old male presented in my practice with a chief complaint of recession. Multiple buccal recession defects ranging 2-5 mm were noted by teeth #11-14 with a minimal amount of keratinized tissue on the buccal of #14. Bone levels were within normal limits with no loss of interproximal tissue observed. These recession defects are classified as Miller Class I recession defects. Typically, 100% root coverage is expected for recession defects of this type.
My Treatment goals included completing root coverage of the recession defects and augmentation of the width of attached keratinized tissue by tooth #14. My patient had similar recession defects on teeth #3-6 which were previously treated with an autogenous sub-epithelial connective tissue graft. Instead of autogenous tissue grafting, Geistlich Mucograft®, a xenogenic collagen matrix, was used in conjunction with a coronally advanced flap.
This case illustrates the successful use of Geistlich Mucograft®, a xenogenic collagen matrix, for the treatment of multiple adjacent recession defects. Complete root coverage and an increase in the zone of keratinized tissue was obtained and a dento gingival complex that is amenable to long-term health and stability was achieved. My patient was spared from the inevitable morbidities associated with a sub-epithelial connective tissue graft from a palatal donor site.
Keys to Success
1. Tedious flap management
> Adaptation of the flap to the recipient bed
> Tension-free coronal postioning of the flap
2. Passive adaptation of the graft matrix
3. Complete graft coverage
