Cervical lesion surgical treatment

Cervical lesion treatment options of Connective Tissue Graft or Alloderm

Etiology of cervical lesions is multi-factorial.

Surgical treatment options for noncarious cervical lesion (NCCL)

Traditional CT Graft = Gold Standard

  1. Roughen area (mircoetch)
  2. Bond RMGI
  3. Horizontal incisions at right angle to adjacent interdental papilla 1mm apical to NCCL
  4. Oblique incisions past mucoginigval junction from there
  5. Split thickness flap apically for release
  6. De-epithelize adjacent tissue
  7. CTG from palate to cover restoration
  8. Coronally reposition flap
  9. Suture PGA (Sling suture)
  10. No brushing
  11. CHX
  12. 7 days suture removal

If color change after the years may need composite over whatever is exposed.

CTG vs Acellular dermis

Tunnel vs flap

  • Flap more width less technique sensitive everything else about the same 1
  • Flap had more coverage than tunnel 1

Tunnel technique

  1. 800mg ibuprofen. 1 min CHX
  2. Intrasulcular incision along facial of anteriors
  3. Orban used to full thickness flap
  4. Root planing to reduce root prominence and smooth surfaces
  5. ADM 5mmx40mm through one side out the other
  6. ADM secured with continuous 4.0 plain gut
  7. Gingiva coronally advanced with continuous chromic 4.0 gut
  8. 3x3x3 rule
  9. CHX bid without brush or floss for 1 week
  10. 1 week remove sutures, gentle brush and floss for another week, stop CHX

Final steps

After graft is placed and gingiva is secured over the graft and root surfaces, the vertical incisions are closed.

Alternative is to detach gingival flap from interdental papilla at isolated sites less esthetically critical but more technique sensitive.

Acellular dermis coronally advanced flap LAVA technique laser-assisted vesibuloplasty approach 1

  1. Laser split-thickness vestibuloplasty slightly above mucoginival junction
  2. Removal of muscle and or frenum pulls
  3. Measurement of acellular dermis
  4. Papilla sparing flap procedure one tooth mesial and distal to area being treated
  5. Flap is full thickness to mucoginigval juntion
  6. Split-thickness by blunt dissection from there, taking care not to enter previous vestibuloplasty
  7. Check for tension free closure to new coronal position
  8. Root planing of tooth
  9. Citric acid treatment
  10. De-epithelize the papilla with #4 round diamond in papilla area
  11. Secure pre-measured dermis soaked in PRP from palatal to lingual with non-resorbable continuous sling (allows palatal removal in 1 month)(nylon or polypropylene)
  12. Buccal flap coronally repostioned with interrrupted sling suture with PGA
  13. Periosteal securing resorbable suture secure superior to repositioned tissues
  14. Flap sutures removed 2-3 weeks
  15. Dermal sutures removed 1 month
