C.H. 26 Principles of Periodontal surgery: Periodontal Regeneration
Periodontal regenerative surgery
Objectives
Periodontal tissue regeneration surgery
Personal statement
bone graphs
Surgery: Open Flap Debridement
Surgery:Bone Grafts and Bone Substitutes
Autografts, allografts, alloplasts and xenografts
Autografts = living bone from pt own body
Allografts = freeze dried bone from cadavers
Alloplasts = manufactured synthetic
Xenografts = from other species
Personal Statement
can be synthetic or naturally occurring
Properties of Bone Grafts and Bone Substitutes
Divided into osteogenesis, osteoinduction and osteoconduction
Biological and Growth Factors
Naturally occurring proteins
Platelet rich plasma
Autologous platelet concentrations
Bone Grafts and Bone Substitutes: Surgical Procedure
Flap is cut, debrided, then defect is filled
Guided Regeneration
Cells Involved in Regeneration
Gingival epithelium
gingival connective tissue
PDL
Alveolar bone
cementum
Guided tissue regeneration
Surgical Procedure
Barrier membranes
Types of Barrier Membranes
Nonabsorbable Membranes
Has to be removed
Absorbable Membranes
Must be left in place for 3-4 weeks
Personal Statement
Some bacteria can adhere to it
Types of Barrier Membranes
Regenerative Surgery: Post op care
Pt oral home care is the most important
Root Surface Treatment
