Here is your complete, easy-to-remember summary of Alveoloplasty based on your notes:
🦷 ALVEOLOPLASTY - The Easy Guide
What Is It? (One-Line Definition)
Surgical reshaping of the alveolar (jaw) bone to remove bony projections, sharp crestal bone, and undercuts - usually done at the time of tooth extraction.
Memory hook: "Alveoloplasty = SMOOTH the ridge"
Primary Alveoloplasty - Remember This First
| Point | Detail |
|---|---|
| When? | Always done at the time of extraction (single or multiple) |
| Why? | Smooths bone for future denture fitting |
DEAN'S Intraseptal / Intercortical Alveoloplasty
Quick Identity Card
| Feature | Detail |
|---|---|
| Proposed by | Dean, in 1936 |
| Where used | Maxilla only - mainly anterior region |
| Main purpose | Reduce gross maxillary overjet |
| Timing | Immediately after extractions of protrusive upper front teeth |
What makes Dean's special? 3 Key Features:
- Reduces cancellous bone volume - but keeps the stress-bearing cortical bone intact
- Reduces buccal undercut / labial prominence - WITHOUT significantly reducing ridge height
- Indicated when: adequate bone height exists BUT a buccal undercut is the problem
Dean's Procedure - Step by Step (A to F)
Use the mnemonic: "All Indians Cut Vertical Cuts Carefully"
| Step | What Happens | Memory |
|---|---|---|
| (A) Atraumatic Extraction | Extract teeth without trauma | A = Atraumatic |
| (B) Bone septa cut | Interdental septal bone cut canine-to-canine using rongeur or fissure bur | B = Bone cut |
| (C) Cut septa removed | All septa from canine to canine are removed | C = Clear septa |
| (D) Vertical + Horizontal cuts | Vertical cuts in labial cortex at distal canine socket + horizontal cuts at socket base (dome bur), WITHOUT perforating labial mucosa | D = Dome bur cuts |
| (E) Elevator fractures cortex | Periosteal elevator placed at base of canine sockets bilaterally - labial cortex is fractured | E = Elevator fractures |
| (F) Fracture compressed + sutured | Digital pressure compresses labial plate toward palate - labial & palatal plates approximate - sharp margins filed - suture placed | F = Finish & close |
Visual Summary of the Steps (from your diagrams)
A: Multiple teeth extracted → empty sockets
B: Pointed septal bone peaks visible
C: All septa between canine-to-canine removed
D: Vertical incisions joined by horizontal base cuts
E: Buccal/labial cortex fractured with elevator
F: Buccal plate compressed inward → sutures placed
Quick Comparison Trick
| Feature | Primary Alveoloplasty | Dean's Alveoloplasty |
|---|---|---|
| Location | Any jaw | Maxilla only (anterior) |
| Timing | At extraction | At multiple extractions |
| Goal | Smooth sharp bone | Reduce overjet + buccal undercut |
| Ridge height affected? | Yes (reduced) | No (height preserved!) |
One Final Memory Anchor for Dean's
"DEAN Does It In the Maxilla - Collapses the Buccal Without Losing Height"
- Dean 1936
- Anterior maxilla
- No ridge height loss
