  • 3. IntroductionIn 1967 Kydd and Mandley stated that tissue lining materialspermit wider dispersion of forces and hence, aid to decrease theforce per unit area transmitted to the supporting tissues.For practical purposes, denture base materials are made ofrigid materials.The dentist must recognize that the prolonged contact of thesebases with the underlying tissues is bound to elicit changes in thetissues.Mucosal health may be promoted by hygienic and therapeuticmeasures and tissue-conditioning techniques may be appliedwhen appropriate.
  • 4. CompositionTissue conditioners are composed of polyethylmethacrylate anda mixture of aromatic ester and ethyl alcohol.Tissue conditioners are available as three component systems Polymer(Powder) Monomer(Liquid) Liquid plasticizer(Flow control)A gel is formed when these materials are mixed, with the ethylalcohol having a greater affinity for the polymer.
  • 5. Uses of Tissue ConditionersTissue treatmentTemporary obturatorBaseplate stabilizationTo diagnose the outcome outcome of resilient linersLiners in surgical splintsTrial denture baseFunctional impression material
  • 6. Adjuncts for Tissue HealingAdvantage of using tissue conditioner is that they prepare theselected oral structures to withstand all the stress from theprosthesis.Tissue conditioners are generally used to preserve the residualridge.Also used to heal irritated hyperemic tissues prior to denturefabrication.
  • 7. Temporary ObturatorTissue conditioners may be added as a temporary obturatorover existing complete or partial denture.This may be done directly in mouth or indirectly after animpression of the surgical area has been made.
  • 8. Stabilization of Baseplates & Surgical Splints or StentsWhen undercuts are present on an edentulous cast, an acrylictemporary denture base cannot be used as it may get locked intothe undercut and break the cast during removal.In such cases tissue conditioners of stiffer consistency may beused to stabilize the record bases and prevent breakage of thecast.
  • 9. Adjuncts to an Impression or as a Final Impression MaterialThese materials are used when it is difficult to determine theextent of the denture base due to presence of movable oralstructures.These materials record the extension of the denture in adynamic form that will later help in preparing an impression trayfor the final impression.
  • 10. Adjunct to determine thePotential Benefits of a Treatment ModalitySometimes patients with well constructed dentures developchronic soreness and find it difficult to wear the denturescomfortably.Tissue conditioners can be used to determine if this problem canbe resolved with the use of resilient liner.
  • 11. Procedure for Applying Tissue ConditionersThe following steps must be considered while applyingtissue conditioners on a denture.Preparation of the denturesThe tissue part of the denture base, which crosses anundercut, should be reduced.The tissue surface of the denture, which covers thecrest of the ridge, should be reduced by 1 mm.
  • 12. It should be remembered that the dentures should allowsufficient room for the placement of the tissue conditioner in orderto promote the recovery of displaced and traumatized tissues.Mixing & placement of the tissue conditionerTissue conditioners are available as three component systems Polymer(Powder) Monomer(Liquid) Liquid plasticizer(Flow control)The mixing ratio can be changed according to consistencyrequired. A ratio of 1.25 parts of polymer, 1 part monomer and0.5cc plasticizer is usually recommended. The plasticizer shouldbe added to the monomer.The ingredients are mixed to form a gel, which is applied insufficient thickness to the tissue surface of the denture.The denture is inserted and border movememts are carried outto mould the setting material.
  • 13. Care & maintenanceTissue conditioners should not be cleaned by scrubbing with ahard brush in order to prevent tearing of the material. The use ofsoft brush under running water is recommended.The greatest virtue of tissue conditioners is their versatility andease of use.The biggest flaw is that they are also misused.Their longevity against wear is very limited and they tend toharden and roughen within 4 to 8 weeks due to the loss ofplasticizer. Hence, they require observation.
  • 14. ConclusionAlthough tissue conditioners can be easily used but theprolonged contact of these bases may elicit changes in theunderlying tissues, they may traumatize the oral tissues.
