Pre-prosthetic surgery Flashcards
What is the aim for pre-prosthetic surgery?
Provide an ideal denture-bearing area for prosthesis/prosthodontic replacements thereby improving satisfactory stability and retention
Examples of pre-prosthetic surgery
- Tooth extractions (impacted tooth, septic/retained roots, malpositioned/nonfunctional teeth)
- Eliminations of pathology
- removal of cyst
- fibrous dysplasia after dormancy can recontour jaw
- not practical for paget’s disease, unless you treat the disease itself - Bone contouring
- Orthognathic surgery
- Soft tissue procedures
- Implant surgery
What procedures fall under bone contouring procedures?
- Alveoloplasty (bony spicules, undercut)
- Mylohyoid reduction
- Tuberosity reduction
- Genoid tubercle reduction
- Removal of tori/ exostosis
- Augmentation of atrophic alveolar ridge
Why is it beneficial to do bone contouring at early stage especially for women?
Women are more prone to diseases like osteoporosis, may take bisphosphonates, causing MRONJ when surgical bone contouring is done
What is the name of the surgical method of removing torus palatinus?
Open book technique (idk if this is legit but yjf mentioned it)
After removal of bone, use acrylic plate to push up the palate, so that gravity doesn’t cause blood clot to form, which would result in soft tissue bump forming as the surgical site heals
How is augmentation of atrophic alveolar ridge done?
Placement of mesh, hip bone graft
What soft tissue procedures are done?
- Frenectomy- labial/lingual
- Excision of hyperplastic tissue (inflammatory fibrous hyperplasia)
- Vestibuloplasty- sulcus deepening eg laser vestibuloplasty
What are the benefits of implant placement pre-prosthetic surgery
Implant supported prosthesis, increased support, path of insertion
What is the lefort procedure
Type of orthognathic surgery. It is a skeletal base osteomy procedure where tooth bearing maxillary component is spearated from superior maxilla with bony palate to correct maxillary deformities
