Study Notes
Postoperative Healing Stents
- Aim to promote healing and minimize complications following surgical procedures.
Stents for Plastic Surgery of the Oral Mucosa
- Used in intra-oral surgeries, such as vestibuloplasty (sulcus deepening procedure) or removal of soft tissue malignancy.
- Required to maintain skin grafts in place until revascularization occurs from the underlying raw area (skin or mucous graft inlay stent).
- Used after ridge augmentation.
Palatal Stent (Palatal Pressure Plate)
- Functions:
- Apply pressure to soft tissues after surgery to facilitate healing and prevent collapse.
- Facilitate hemostasis and avoid hematoma formation.
- Used after surgeries in the palate, such as tori removal, palatal mucosal grafting, or removal of impacted canine or large cyst in the palate.
Anti-Hemorrhagic Stent
- Used to control bleeding after tooth extraction in patients with:
- High bleeding tendency (e.g., leukemic patients).
- Clotting problems (e.g., hemophilic patients).
- In patients with high bleeding tendency, the stent applies pressure over the extraction socket to stop bleeding until the late coagulation mechanism starts.
Fabrication of Anti-Hemorrhagic Stent
- Upper and lower impressions are made before surgery.
- Impressions are poured to obtain casts, which are mounted in centric relation using an inter-occlusal record.
- The tooth to be extracted is removed from the stone cast.
- A layer of molding wax is adapted to cover the lingual, buccal, and top surface of the ridge.
- The articulator is closed to allow the opposing teeth to touch the top of the wax.
- The wax is processed in clear heat-cured acrylic resin or cold-cured resin.
- The stent is inserted immediately after extraction, where bleeding is controlled as the patient closes and applies gentle pressure over the extraction site.
- The stent gains its retention by using wrought wire.
