A study to compare the accuracy of various impression techniques of elastomeric impression materials used in fixed prosthodontics
Shazia Mir, Randhir Singh
Abstract :
The aim of the study was to compare the dimensional accuracy of impressions obtained from six techniques. Six impressions were made with each of six different techniques and divided in to group 1 to 6. Casts were poured and inter–abutment/ intra abutment distances were measured.full arch wax spacer was most accurate followed by dual arch 1–step, quadrant arch wax spacer, full arch polyethylene, quadrant arch polyethylene, in that order, dual arch twostep was least accurate.dies were larger in all the techniques except buccolingual dimension of dual arch technique. This deviation ranged from7µ to –18 µ in mesio–distal direction while it was –29µ to 28µ in bucco–lingual direction. Results show that clinically acceptable impressions can be made with all the techniques except dual arch 2 step technique.
