  5. Correct interocclusal distance
  6. Satisfactory Speech with existing Teeth arrangement
  7. Absence of severe osseous undercuts and soft tissue defects

Indications of Relining and Rebasing:

  1. Immediate dentures at 3-6 months after fabrication

  3. When the patient cannot afford new dentures
  4. When the construction of new dentures with their prolonged steps can cause physical and mental stress for geriatric and chronically ill patients

Contra-indications of Relining and Rebasing:

  1. When excessive amount of resorption is seen
