INSERTION, RELINING AND REBASING

TOPIC: INSERTION, RELINING AND REBASING

🎯 KEY POINTS: 

🔹Shim stocks are useful in verifying the presence and location of the occlusal contacts.

🔹Spoon denture is the maxillary interim RPD which is without clasp and whose palatal resin base resembles the shape of the spoon.

🔹It is usually used during periodontal treatment.

🔹RPD is preferred in periodontally compromised dentition as it provides cross-arch stabilization.

🔹Lingual plate prevents food impaction between the interproximal spaces between the teeth.

🔹Disjunct dentures are special type of stress breakers which consist of a bar and a slot.

🔹Spoon Denture resembles a spoon.

🔎 Post Insertion Instructions To The Partial Denture Patient

🔸The patient is advised for possibility of minor discomfort with the use of artificial prosthesis.

🔸The patient can have difficulty with speech and during eating.

🔸The patient is advised to maintain proper hygiene.

🔸After every meal, the dentures should be cleaned with a small stiff brush.

🔸The patient is advised to soak the dentures in cleansing solution for at least 15 min once daily.

🔸The patient should always remove the denture at night and place it in a water-filled container.

🔸The patient should follow strict follow-up regime.

🔸There may be a possibility of gagging with the new prosthesis.

🔸The patient should be taught the insertion and removal of the prosthesis in determined path of placement.

🔸The patient should never bite on the prosthesis to seat it.

🔎 Insertion And Postinsertion Problems And Their Management In Relation To RPD

🔸 To accurately fit the denture base to the edentulous ridge

🔸 To adjust the retentive clasps and correct occlusal discrepancies, if any

🔸 To instruct the patient on the maintenance of the prosthesis

 

✳️ Problems Encountered During Insertion

🔸Problems regarding correct fit of the denture base

🔸Occlusal discrepancies

🔸Problems with the retention of the prosthesis

 

✳️Problems During Post Insertion

⭐Irritation of the soft tissues

  • Overextended denture base
  • Tissue side of the denture base is rough
  • Occlusal prematurities or discrepancies

⭐Irritation of the hard tissues

⭐Miscellaneous problems

  • Gagging
  • Cheek biting
  • Tongue biting
  • Pain on chewing
  • Problems with phonetics

 

📌 RELINING: The procedure used to resurface the tissue side of the removable dental prosthesis with new base material, thus producing an accurate adaptation to the denture foundation area. (GPT 8th Ed)

💠 Inspected By Two Methods:

🔸Using thin mix of alginate

🔸Finger pressure

 💠 Method Of Relining:

🔸Intraoral reline

🔸Laboratory reline

📌 SPECIAL REMOVABLE PARTIAL DENTURES

💡Guide Plane Removable Partial Denture

  • Used to stabilize periodontally weakened teeth in three directions, i.e. mesiodistally, vertically and buccolingually.
  • Guide plane RPD consists of multiple guide planes, multiple rests,clasps and rigid major and minor connectors 

💡Role Of Lingual Plate

💡Disjunct Denture: Any component of the prosthesis that serves to allow movement between two or more parts. (GPT 8th Ed)

💡Spoon Denture: A maxillary provisional removable dental prosthesis, without clasps, whose palatal resin base resembles the shape of a spoon. (GPT 8th Ed)

💡Computer-aided RPD Designing
