  • 1. INDIAN DENTAL ACADEMY Leader in continuing dental education www.indiandentalacademy.com www.indiandentalacademy.com
  • 2. Pre Prosthetic Surgery Definition: “Surgery performed to prepare the remaining oral tissues to best support a prosthesis” www.indiandentalacademy.com
  • 3. Pre Prosthetic Surgery Objectives To provide a comfortable tissue foundation to support the denture Proper jaw relationship in the anteroposterior, transverse and vertical dimensions. Alveolar processes that are as large as possible and of the proper configuration. (The ideal shape of the alveolar process is a broad U-shaped ridge with the vertical components as parallel as possible. www.indiandentalacademy.com
  • 4. Pre Prosthetic Surgery Objectives No bony or soft tissue protuberances or undercuts. Adequate attached keratinized mucosa in the primary denture-bearing area. Adequate vestibular depth. Adequate form and tissue coverage for possible implant placement www.indiandentalacademy.com
  • 5. Pre Prosthetic Surgery Patient evaluation & treatment planning History Physical examination – Evaluation of supporting bony tissue Evaluation of supporting soft tissue www.indiandentalacademy.com
  • 6. Pre Prosthetic Surgery Classification - Corrective Procedures - Ridge extension procedure - Ridge augmentation www.indiandentalacademy.com
  • 7. Pre Prosthetic Surgery Corrective Procedures • Soft tissue – – – – Frenectomy Excision of flabby ridges Excision of denture induced granuloma Reduction of fibrous tuberosity • Hard tissue – Alveoloplasty – Removal of Tori www.indiandentalacademy.com – Tuberosity reduction
  • 8. Pre Prosthetic Surgery Bony Recontouring of the alveolar ridges - Simple alveoloplasty associated with multiple removal of teeth - Compression of the lateral walls www.indiandentalacademy.com
  • 9. Pre Prosthetic Surgery Knife edge www.indiandentalacademy.com
  • 10. Pre Prosthetic Surgery Intraseptal alveoloplasty Deans technique • Involves removal of the intraseptal bone and repositioning of the labial cortical bone • Done immediately after tooth extraction or in the initial post operative healing period • Technique is best used when the ridges of regular contour and adequate height but presents an undercut to the depth of the labial vestibule www.indiandentalacademy.com
  • 11. Pre Prosthetic Surgery Advantages Labial prominence of the ridge can be reduced without significantly reducing the height of the ridge www.indiandentalacademy.com
  • 12. Pre Prosthetic Surgery Intraseptal alveoloplasty • Periosteal attachment to the underlying bone,this reduces the post operative bone resorption and remodeling. • Muscle attachment to the alveolar ridge can be left undisturbed. www.indiandentalacademy.com
  • 13. Pre Prosthetic Surgery www.indiandentalacademy.com
  • 14. Pre Prosthetic Surgery Maxillary tuberosity reduction • Horizontal or vertical excess of the maxillary tuberosity area can be due to bone excess soft tissue both Pre operative evaluation • Clinical examination • Radiographic examination to locate the floor of the maxillary sinus www.indiandentalacademy.com
  • 15. Pre Prosthetic Surgery Objective • To provide adequate interarch space • A firm mucosal base of consistent thickness Procedure for hard tissue www.indiandentalacademy.com
  • 16. Pre Prosthetic Surgery Procedure for soft tissue www.indiandentalacademy.com
  • 17. Pre Prosthetic Surgery Mylohyoid ridge reduction www.indiandentalacademy.com
  • 18. Pre Prosthetic Surgery Genial tubercle • Reduction or augmentation www.indiandentalacademy.com
  • 19. Pre Prosthetic Surgery Maxillary Tori • • • • Bony exostosis in the palate Origin is unclear Found twice as much in females than in males Single smooth elevation to multiloculated pedunculated mass • Speech problems,ulcers,interferes with prosthesis • Usually present in the midline www.indiandentalacademy.com
  • 20. Pre Prosthetic Surgery Maxillary tori www.indiandentalacademy.com
  • 21. Pre Prosthetic Surgery Mandibular tori • • • • Present on the lingual aspect Usually premolar area Gradually increase in size May interfere with speech or tongue movement • Rarely requires surgical intervention when dentition is present www.indiandentalacademy.com
  • 22. Pre Prosthetic Surgery Mandibular tori www.indiandentalacademy.com
  • 23. Pre Prosthetic Surgery www.indiandentalacademy.com
  • 24. Pre Prosthetic Surgery Unsupported hyper mobile tissue • It is caused due to resorption of underlying bone or ill fitting denture • Treatment • augmentation of bone • soft tissue excision • Complication • obliteration of buccal vestibule due to undermining www.indiandentalacademy.com
  • 25. Pre Prosthetic Surgery www.indiandentalacademy.com
  • 26. Pre Prosthetic Surgery Inflammatory fibrous hyperplasia • Epulis fisuratum • Commonly caused by ill fitting denture • Treatment • initial stages– denture with a soft liner • significant fibrosis – excision of the hyperplastic tissue electro surgical surgical excision www.indiandentalacademy.com
  • 27. Pre Prosthetic Surgery www.indiandentalacademy.com
  • 28. Pre Prosthetic Surgery Inflammatory papillary hyperplasia of palate • Mechanical irritation, poor hygiene, fungal infection • Appears as multinodular projections in the palatal tissue • Treatment • initial stage – denture adjustment with tissue conditioner • Electro surgical excision • Abrade with a rotating hand piece www.indiandentalacademy.com
  • 29. Pre Prosthetic Surgery www.indiandentalacademy.com
  • 30. Pre Prosthetic Surgery Labial frenectomy • It is a thin band of fibrous tissue covered with mucosa extending from the lip and cheek to the alveolar periosteum. • Surgical techniques simple excision z plasty localised vestibuloplasty www.indiandentalacademy.com
