| ABSTRACTBackground: the purpose of this study was to compare the periodontal status in patients receiving partial denturesconstructed from conventional and altered cast impression techniques.Materials and Methods: twenty patients receiving mandibular bilateral distal extension removable partial dentureswere assigned for treatment, the patients divided into ten patients receiving partial dentures constructed fromconventional impression technique and other ten patients receiving partial dentures constructed from an alteredcast impression technique. The periodontium of the last abutments had been evaluated using gingival bleedingindex and probing pocket depth, the first score have been made at time of insertion, the second score made after3days of insertion, the third score after 10days of insertion, the fourth score after 30 days of insertion, the fifth scoreafter 45 days of insertion and the last score was made after 60 days of insertion. Student t-test had been made toevaluate the periodontal conditions at different time intervals.Results: the results revealed that there would be a decrease in both periodontal indexes scores with time.Conclusion: the use of altered cast impression technique for distally extended removable partial dentures will result ina less stress concentration on the abutment teeth resulting in a proper periodontal health and reducing damage ofperiodontal tissues this will be in addition to proper oral hygiene being established.Key words: Impression technique, distal extension, periodontium, last abutment.
