What do we use to predict the Max amount of root coverage that is possible (hint: anatomy not a classification)
Interproximal bone height
Visually --> 3mm Rule: Measure 3mm from papilla height
Name 3 Indications for Crown Lengthening
1. Subgingival Caries
2. Fracture/Trauma
3. Perforation
4. External Root Resorption
5. Gingival Enlargement
6. Prior to Ortho
7. Biologic Width Impingement
8. Short clinical crowns
This graft property involves the recruitment and stimulation of host cells to form new bone
Osteoinduction
This condition involves inflammation of soft tissue around an implant without bone loss
Peri-implant mucositis
What is the Periosteum?
Specialized Connective Tissue rich in blood supply that overlays the alveolar bone
Name the 3 Subcategories of Cairo Gingival Recession
RT1 = Facial recession w/ no interproximal CAL
RT2 = Interproximal attachment loss < Facial attachment loss
RT3 = Interproximal attachment loss > Facial attachment loss
How do you determine if you are going to do Step Back incisions
Always on palatal tissue
Amount of KT on the Facial (2mm or greater = yes)
What materials would you use for an extraction/ridge preservation and why?
Name what each material is made from
lots
This is the minimum recommended distance between two adjacent implants to preserve inter-proximal bone and papilla
3mm
what is the Eglin Dental Clinic Building Number
2751
Name 3 Differences between a FSTA and CTG
FSTA
- KT <2mm
-Phenotype Conversion
-Increase Vestibule Depth
-Goes on the outside
-Harvest epi + CT
-Decrease muscle activity / eliminate frenum
CTG
-Gold standard for root coverage
-Esthetic color match
-Goes under the flap
How long should you wait after crown lengthening for Final Restorations and why?
Posterior teeth = 6-8 weeks
Anterior teeth
-Temporization = 6-8 weeks
-Final Restorations = 6 months
Gingival rebound and/or recession --> Waiting for stabilization of gingival margins
Name an example of the following:
Autograft
Allograft
Xenograft
Autograft = FSTA, Block Graft, CTG
Allograft = FDBA/DFDBA, Alloderm
Xenograft = Bio-Oss/Bio-Oss Collagen, Mucograft, Fibrogide
Name the difference types of bone quality and where you would expect to find each one
Type I - Thick and dense cortical bone w/ no cancellous bone (Anterior Mandible)
Type II - Thick and Porous cortical bone w/ course cancellous bone (Anterior Man, Posterior Man, Ant Max)
Type III - Thin and porous cortical bone with fine cancellous bone (Ant Max, Post Max, Post Man)
Type IV - Primarily fine cancellous bone (Posterior Maxilla)
Name 4 ways you can manage hemostasis intraoperative
1. Direct Pressure
2. Vasoconstrictors (i.e. Lido w/ epi)
3. Local agents (Surgical, bone wax, collatape, topical thrombin)
4. Ligating sutures
What is Emodgain?
Biologic --> Enamel Matrix Derivative
-Enamel matrix proteins from developing porcine teeth
-Induces cementogenesis and regeneration
What are the types of Intrabony Defects, what is it based off of, and what is the best for grafting
Based on # Walls Remaining
One wall
Two wall (Crater)
Three wall = best for grafting
Circumferential
What is Chlorhexidine and what are side effects
Broad Spectrum Cationic Bisbiguanide
eliminates bacteria/plaque
Side Effects
- Taste, Staining, increased tartar due to increased uptake of Calcium and Phosphate Ions
Name some anatomic differences between a natural tooth and implant
Would you expect a natural tooth or implant to have deeper Probing Depths and Why
Periodontal Attachment
-Junctional Epithelium
-Dentogingival Fibers in all directions
-PDL
Peri-Implant Sulcus
-No true tissue connection
-Naturally deeper sulcus
-Parallel or Circular Fibers
what is widely considered one of the only foods that never expires?
Honey
What are the names of the 2 types of Sutures you use for securing a FSTA and the purposes of both?
1. Tacking Sutures--- secure the graft down
2. Compression Sutures-- eliminate dead space, compress against blood supply
Name the steps in order for Osseous Surgery (6-7 Steps)
1. Bulk Reduction
2. Interdental Fluting
3. Eliminate Crater wall
4. Thinning of Marginal Radicular Bone
5. Removal of Widow's Peak
6. Physiologic architecture
7. Final shaping and smoothing of alveolar bone
What are the 4 core principles of GBR (PASS principles)
Primary wound closure
Angiogenesis
Space maintenance
Stability
In the esthetic zone, this is the ideal vertical distance from the contact point to the crest of bone to allow predictable papilla fill
Greater than or equal to 5mm
How many spots does the average Cheetah have?
2000-3000
