Tissue Conditioners
Tissue conditioners are for the short time use only, i.e. for few days only. Most commonly PMMA soft lining materials are used on the tissue surface of dentures to act as tissue conditioner.
Composition Of tissue conditioners
- Powder: Polymethyl methacrylate polymer beads
- Liquid: Ethyl alcohol—solvent; Butyl phthalate/butyl glyco- late—plasticizer
“Difference Between Tissue Conditioners And Permanent Soft Liners”
Properties Of tissue conditioners
- Tensile strength is 0.80 to 0.83 MPa
- Percentage elongation is 150 to 300%
- Hardness is 30 to 95 KHN
- Tear resistance is 29 to 260 N/cm.

“Early Signs Of Problems With Tissue Conditioner Application”
Manipulation Of tissue conditioners
- The denture base is relieved on the tissue surface.
- Mix powder and liquid together to form a gel and place it on the tissue surface of the denture and insert it in the mouth.
- Gel flows readily to fil the space between the denture base and oral tissue.
“Importance Of Tissue Conditioners For Denture Wearers”
Indications Of tissue conditioners
- For conditioning abused basal tissues before fabrication of denture.
- As reline material in surgical obturator.
- For stabilizing, enhancing retention and comfort of temporary denture base at the time of recording maxillomandibular relations.
- As functional impression material.
Advantages Of tissue conditioners
- It has ideal viscoelasticity
- It provides a good fit to dentures
- A chairside application is present.
Disadvantages Of tissue conditioners
- It has low cohesive strength
- It has alcohol which act as irritant.
“Risk Factors For Improper Use Of Tissue Conditioners”
Tissue Conditioners Care and Maintenance
- Tissue conditioners should not be cleaned by scrubbing with a hard brush in order to prevent tearing of the material.
- The use of soft brush under running water is recommended.
- Their biggest flaw is that they are so easily misused
“Understanding The Role Of Tissue Conditioners In Modern Dentistry”
- Their longevity against wear is very limited and they tend to harden and roughen within 4 to 8 weeks due to the loss of plasticizer.
- Hence, they require close observation.
