1) Jaw reconstruction is needed after surgical removal of oral tumors to address osseous defects and patient concerns about function and cosmetics. 2) Ridge augmentation using bone grafts or synthetic grafts can provide an osseous base for dentures or bridges. 3) For large maxillary defects, surgical closure or bone grafts are used for smaller areas, while obturators are used for very large defects or poor surgical risks.

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
