  1. 1. Diagnosing denture problemsusing pressure-indicating mediaPressure-indicating media have long beenadvocated for use in diagnosing problems withdentures at insertion and denture adjustmentappointments. Typically, pressure indicators areused to identify problems related to impingement,extension, and/or width of prostheses.Slide No. 1 Dr. Shikha Gupta, Dr. Laxmi Chhuchhar Poster No. 5
  2. 2. Coat denture with enough paste so base is primarily color of medium, with streaks in paste as on left. Too little (upper right) or too much (lower right) can make interpretation more difficult. Apply paste well over flange edge onto buccal surface. Lines of burn-through on flanges often indicate overextended or overcontoured areas. Note double line of burn-through on facet where denture has already been adjusted.Slide No. 2 Dr. Shikha Gupta, Dr. Laxmi Chhuchhar Poster No. 5
  3. 3. Use indicating medium on non bearing surfaces of dentures to disclose problems such as impingement by coronoid process in lateral excursions. Interferences can cause both pain and loosening of dentures. A, External contours of dentures can be evaluated with media. Bulky gingival contours around teeth have no paste. B, After functional movements, bulky flanges have no paste. Thin these areas, if patient has problems with loosening or discomfort.Slide No. 3 Dr. Shikha Gupta, Dr. Laxmi Chhuchhar Poster No. 5
  4. 4. Undercut areas will cause paste to be wiped off and will appear to need adjustment. Use caution in these areas. Use of indicating medium for adjustment of hamular notch areas is critical, as removal of acrylic resin in incorrect areas can result in breach of posterior palatal seal, resulting in decreased retention. Areas with streaks remaining in paste have not contacted tissue (N). Areas of paste with no streaks represent acceptable contact (C). Areas without paste represent areas of tissue impingement (I).Slide No. 4 Dr. Shikha Gupta, Dr. Laxmi Chhuchhar Poster No. 5
  5. 5. Case Discussion Well-adjusted denture base. Areas of tissue inflammation that do not correlate to areas of burn-through are most likely caused by tilting of dentures, possibly due to occlusal problems. While primarily used to locate areas on the denture base that cause pressure and pain,8 pressure-indicating media have diverse applications for identification of a variety of denture-related problems. Pressureindicating media can be nonsetting and cream-based , nonsetting aerosol powders , or media that polymerize .Slide No. 5 Dr. Shikha Gupta, Dr. Laxmi Chhuchhar Poster No. 5
  6. 6. ConclusionUse of an indicating medium is one of severalstrategies that clinicians can employ forimproving diagnosis and correction of denture-related problems. Denture adjustments aremore accurate and effective when made usingan indicating medium. The authorsrecommend that the use of pressure-indicatingmedia for adjusting dentures should becomeroutine.Slide No. 6 Dr. Shikha Gupta, Dr. Laxmi Chhuchhar Poster No. 5
