Study Notes
Preprosthetic Surgery and Ridge Resorption
- The primary objective of preprosthetic surgery is to prepare an ideal alveolar ridge for successful denture construction.
- Ridge resorption is more prominent in the mandible due to the thin cortical layer and the direction of the NO forces on teeth and periodontal ligament.
- Accelerated ridge resorption in the mandible can be contributed by factors such as the direction of NO forces, parafunction, and periodontal disease.
- Bony changes in the jaws begin to take place after the loss of natural teeth, with the mandible undergoing more resorption than the maxilla.
- The ideal characteristics of an alveolar ridge for best denture support include being flat, wide, and with a smooth surface.
Preprosthetic Surgery Procedures
- Preprosthetic surgery includes procedures such as alveoloplasty, exostosis removal, and nerve repositioning.
- Alveoloplasty is used to remove bony undercuts, sharp bony edges, and overgrowths.
- Exostosis removal is used to remove excess bone and improve the contours of the alveolar ridge.
- Nerve repositioning is used to reposition the nerve to enable successful denture placement.
Ridge Resorption Classification
- Resorption of the maxillary alveolar ridge can be classified into three types: flat-ridge form with loss of alveolar process, knife-edge form, and high and narrow form.
Ridge Augmentation and Vestibuloplasty
- Ridge augmentation is used to enhance the dimensions of the alveolar ridge.
- Vestibuloplasty is used to treat inadequate alveolar ridge height by deepening the sulcus.
- The Vestibuloplasty with tissue Grafting technique involves deepening the sulcus and adding tissue to enhance the ridge dimensions.
Other Procedures
- Intraseptal alveoloplasty is used to remove interseptal bone and improve the contours of the alveolar ridge.
- Tori removal is used to remove large tori to enable successful denture placement.
- Z-plasty procedures are used to reduce the amount of vestibular ablation after linear excision of a frenum.
- Frenum removal may be needed for orthodontic or preprosthetic purposes.
Importance of Preprosthetic Surgery
- Preprosthetic surgery is crucial for successful denture construction, as it enables the creation of an ideal ridge for denture support.
- Irregularities of the alveolar bone can lead to difficulties in denture construction if not recontoured before construction.
- Soft tissue adjustments are necessary to ensure a comfortable and functional denture.
- Nerve repositioning is necessary to prevent nerve damage and ensure successful denture placement.
