2. RECONSTRUCTION OF JAWS

3. RECONSTRUCTION
• Surgical removal of oral tumorOsseous
defect
• Range of defect i) loss of alveolar bone
ii) loss of major portion of
jaw

4. RECONSTRUCTION
• Patient concerns i) functional
ii) cosmetic

5. surgical reconstruction
• Loss of alveolar bone– need for osseous base
for bridge/partial or complete denture
• Ridge augmentation to form an osseous base

6. RIDGE AUGMENTATION

7. AUGMENTATION OPTIONS
• BONE GRAFTS
• SYNTHETIC BONE GRAFTS
• COMBINATION

8. BONE GRAFTS

9. SYNTHETIC BONE GRAFTS

10. MAXILLARY DEFECT
• Continuation of nasal cavity or maxillary
sinuses with oral cavity
• Difficulty in speaking,eating,drinking

11. Maxillary Defect Reconstruction
• OPTIONS
1) SURGICAL
2) PROSTHODONTIC

12. Surgical option
• Less extensive defect:
• Closure with available soft tissues of buccal
and palatal mucosa

13. Surgical option
• 2) Bone grafts :provides functional alveolar
process

14. prosthodontic
• Very large defects
• Poor surgical risks
Obturators

15. TIMING OF RECONSTRUCTION
• Immediate(at the time of surgical removal)
• Delayed
• Benign tumors resection—immediate
reconstruction
• Malignant tumors----delayed reconstruction

16. Delayed reconstruction after removal
of malignant tumor
REASONS
• 1) To prevent bone graft resorption if post op
radiotherpay planned
• 2)more soft tissue required
• 3) recurrence

17. Delayed reconstruction after removal
of benign tumor
• Presence of simultaneous intraoral and
extraoral defects

18. Maintenance of residual fragments
• Delayed reconstruction--- maintenance of
residual fragments :
• Options i) external pin fixation ii) splints iii)IMF
iv) recon plates

19. Maintenance of residual fragments

20. IMMEDIATE RECONSTRUCTION
ADVANTAGES
• Viable option
• Reqiring single surgical procedure
• Early return to function
• Minimal compromise to facial esthetics
DISADVANTAGES
LOSS OF GRAFT DUE TO INFECTION

21. DENTAL REHABILITATION
• DENTAL IMPLANTS
