  2. 2. 218 East 61st Street, New York City
  3. 3. Periodontal Plastic Surgery • Defined as the surgical procedures performed to correct or eliminate anatomic, developmental, or traumatic deformities of the gingiva or alveolar mucosa.
  4. 4. Recession Prevalence and Age Prevalence of Recession % In US >30 58 41 22 13 6 70 60 50 40 30 20 10 0 1 2 3 4 5 Recession Prevalence (%) by Age 18 30 40 46 60 70 60 50 40 30 20 10 0 40 50 60 70 80 Recession (mm) Age 58% of population have at 60% of 80 year olds have recession least 1mm of recession
  5. 5. Why is Prevalence of Recession Important? • Since sites with previous recession are prone to additional recession, the aging U.S. population may have a large number of sites that need root coverage grafting.
  6. 6. Purposes of Treating Recession 1. Prevention: • restoring or increasing marginal width of keratinized gingiva and/or marginal soft tissue thickness  may offer increased resistance to further recession caused by inflammation secondary to plaque in patients with a thin periodontal phenotype (weak evidence)  may guard against factitial injury (faulty toothbrushing) (weak evidence)  pre-prosthetically may protect against iatrogenic dentistry (ie. invading biologic width) (weak evidence)  may offer “protection” to the alveolar bone from resorbing as a result of all of the above (weak evidence)
  7. 7. Purposes of Treating Recession 1. Prevention: • restoring or increasing marginal width of keratinized gingiva and/or marginal soft tissue thickness  prior to orthodontic treatment may prevent or minimize the formation of a dehiscence (strong evidence)
  8. 8. Purposes of Treating Recession 2. Root coverage: • bridging the soft tissue fenestration with either keratinized or non-keratinized gingiva  reduce risk of root caries (strong evidence)  reduce root sensitivity following abrasion, erosion, abfraction or prior to tooth bleaching (strong evidence)
  9. 9. Purposes of Treating Recession 2. Root coverage: • bridging the soft tissue fenestration with either keratinized or non-keratinized gingiva  improve esthetics (very strong evidence)  Pre-prosthetically • prior to crown placement or class V restoration enabling the clinician to control the incis-ogingival dimension of the crown/restoration and to make crown/restoration height compatible with the height of the adjacent teeth • prior to porcelain veneer placement can eliminate the difficult task of bonding to cementum
  10. 10. Purposes of Treating Recession 2. Root coverage: • bridging the soft tissue fenestration with either keratinized or non-keratinized gingiva  improve esthetics (very strong evidence)  Post-prosthetically • may be used to satisfy esthetic requirements such as exposed crown margins or exposed implant abutments eliminating the need to replace existing crowns
  11. 11. First step in treating recession defect(s) is to identify the etiology and correct it ! • What Caused the Gingival Recession? – Tooth malposition • (rotated, tilted, facially displaced teeth) – Faulty tooth-brushing technique – Gingival inflammation – Abnormal frenum attachment – Iatrogenic dentistry (tooth preparation, margin placement, impression taking) – Occlusion? (weak controversial evidence)
  12. 12. Sullivan & Atkins, Per 68 • shallow or deep • narrow or wide • shallow-narrow, shallow-wide • deep-narrow, deep-wide
  13. 13. Miller PD, IJPRD 85 • Class 1: REC not to MGJ, no IP bone or papilla loss, 100% coverage • Class 2: REC past MGJ, no IP bone or papilla loss, 100% coverage • Class 3: REC past MGJ, IP bone or papilla loss, malposition, partial coverage • Class 4: REC past MGJ, severe IP bone or papilla loss, malposition, no coverage
  14. 14. All STG heal by New Attachment • The union of connective tissue or epithelium with a root surface that has been deprived of its original attachment apparatus. This new attachment may be epithelial adhesion and/or connective tissue adaptation or attachment and may include new cementum
  15. 15. ROOT COVERAGE PROCEDURES 1. Pedical flap (repositioning of “adjacent” attached gingiva) • Laterally positioned (AKA repositioned) flap • Coronally positioned (AKA repositioned) flap 2. Coronal advancement of previously placed free gingival grafts 3. Gingival grafts placed directly over the root surface 4. Gingival grafting performed in conjunction with flap advancement for submersion (SECT graft) 5. Guided Tissue Regeneration (GTR)
  16. 16. Cicatrization of the Free Connective Tissue Graft Cicatrization: To heal or become healed by the formation of scar tissue.
  17. 17. ROOT COVERAGE PROCEDURES 1. Pedical flap (repositioning of “adjacent” attached gingiva) • Laterally positioned (AKA repositioned) flap • Coronally positioned (AKA repositioned) flap 2. Coronal advancement of previously placed free gingival grafts 3. Gingival grafts placed directly over the root surface 4. Gingival grafting performed in conjunction with flap advancement for submersion (SECT graft) 5. Guided Tissue Regeneration (GTR)
  18. 18. Subepithelial Connective Tissue Graft Technique for Root Coverage by Langer and Langer (1985) A horizontal incision is placed at the level of the cementoenamel junction of both teeth. This is connected to vertical incisions on either side.
  19. 19. Subepithelial Connective Tissue Graft Technique for Root Coverage by Langer and Langer (1985) A partial thickness flap is elevated. Care is taken to preserve the periosteum apical to the area of recession. The flap is elevated to the mucobuccal fold. Convexities on the denuded roots are flattened with curettes.
  20. 20. Subepithelial Connective Tissue Graft Technique for Root Coverage by Langer and Langer (1985) A view of the palate showing the donor site. Two horizontal incisions are placed 2 to 3 mm apical to the free gingival margin. These are connected by vertical incisions which facilitate flap elevation and connective tissue graft removal.
  21. 21. Subepithelial Connective Tissue Graft Technique for Root Coverage by Langer and Langer (1985) The donor tissue is placed directly over the denuded area. The size of the graft permits it to extend onto the remaining periosteal covering on the nondenuded portion of both teeth. This will help supply circulation to the donor tissue.
  22. 22. Subepithelial Connective Tissue Graft Technique for Root Coverage by Langer and Langer (1985) The donor connective tissue and epithelium are sutured to the underlying connective tissue interproximally. The recipient flap is then sutured directly over the graft. If possible, the flap is pulled over a major portion of the graft to ensure temporary nourishment with an additional source of circulation.
  23. 23. ROOT COVERAGE PROCEDURES 1. Pedical flap (repositioning of “adjacent” attached gingiva) • Laterally positioned (AKA repositioned) flap • Coronally positioned (AKA repositioned) flap 2. Coronal advancement of previously placed free gingival grafts 3. Gingival grafts placed directly over the root surface 4.

  37. 37. The Connective Tissue and Partial Thickness Double Pedicle Graft by Harris (1992) • The greatest advantage of this technique is that a pedicle graft can cover connective tissue grafts on root surfaces lacking a vascular supply. • In addition to root coverage, the width of keratinized gingiva can be increased. Therefore, this technique may be used in areas of gingival recession with narrow keratinized gingiva.
  38. 38. TRADITIONALLY • Augmentation of the gingival complex at the time of root coverage has been performed with autogenous connective tissue (CT) harvested from the palate or edentulous ridge.
  39. 39. Limitations of autogenous CT grafts which have led to the search for non-autogenous substitutes for palatal tissue • Second surgical site morbidity • Limited available quantity

  44. 44. Creeping Attachment • Matter (1980) described a phenomenon of additional root coverage during healing which may be observed between 1 month and 1 year post-grafting. He reported an average of 1.2 mm of coronal creep at 1 year with no additional change.
  45. 45. Acellular Dermal Regenerative Tissue Matrix (ADM) Defined ADM is an acellular dermal matrix derived from donated human skin tissue supplied by US AATB-compliant tissue banks utilizing the standards of the American Association of Tissue Banks (AATB) and Food and Drug Administration's (FDA) guidelines. Since ADM is regarded as minimally processed and not significantly changed in structure from the natural material, the FDA has classified it as banked human tissue.
  46. 46. What is Acellular Dermal Regenerative Tissue Matrix? • A human soft tissue • Used in various applications since 1995 –Burns –Head and Neck Reconstructions –Dental, 1997

  51. 51. Procurement of Alloderm • AlloDerm is a processed tissue that comes from donors who are extensively screened and tested for presence of diseases including HIV and hepatitis. The processing procedure has been demonstrated to reduce HIV and hepatitis C surrogate virus to non-detectable levels. Additional testing for presence of pathogens is performed prior to and following processing to ensure that Alloderm is disease-free before release for patient care.
  52. 52. Processing of Alloderm • A buffered salt solution removes the epidermis, and multiple cell types within the dermis are then solubilized and washed away using a patented series of non-denaturing detergent washes that rapidly diffuse into the dermis.
  53. 53. ADM Processing • Acellular Dermal Matrix is of human origin. • It has been especially processed to remove both the epidermis and the cells that can lead to tissue rejection and graft failure, without damaging the matrix. • The processed tissue matrix is preserved with a patented freeze-drying process that prevents damaging ice crystals from forming.
  54. 54. Regenerative Tissue Martix Cryopreservation The processed regenerative human tissue matrix is then preserved using LifeCell’s patented amorphous freeze-drying process, thereby retaining the critical biochemical and structural components needed to maintain the tissue’s natural regenerative properties. The matrix has a two-year shelf life.

  61. 61. Regenerative Tissue Matrix Transitioning into the host tissue Host cells continue to respond to the local environment, and the matrix transitions into the tissue it is replacing at the site of the transplant. Unique Outcome
  62. 62. Advantages of ADM 1. Equivalent to “gold standard” – Provides effective and predictable root coverage compared to connective tissue 1. Unlimited supply – Multiple sites can therefore be treated with a single procedure (sextant, quadrant, full arch) 1. Excellent tissue color match obtained as the graft is repopulated with the recipient’s cells and the final gingival color exactly matches the recipient’s pre-treatment gingiva
  63. 63. #1/2 Orban DE Knife, Modified Modified with a flattened surface on one side and a domed surface on the other, plus a reduced cutting edge at the shank. Ideal for intrasulcular sharp, supraperiosteal dissection. Used after the initial blunt dissection (using the HF-PPAEL or HF-PPAELA) to complete the preparation of the pouch recipient site. The flat side is positioned against the bone and the domed side faces the soft tissue facilitating dissection without perforation. Reduced cutting surface lessens the possibility of inadvertently incising the pouch margin during dissection.
