functional impression technique

Any other clinical situation that requires a highly precise impression. In the first stage, the dentist makes an impression with a rigid material. This device can be indicated to develop functional impressions for complete dentures using the patient-conducted muscular motion technique. The partial impression captures only a part (segment) of the oral cavity, namely the part where the prosthetic reconstruction is designed. • It is the shape of the ridge before functional load is applied. Sometimes the contraction of a muscle near its insertion can displace the denture, unless it has a groove to accommodate such contractions. Place ball abutment analogues (Zimmer Dental) into cap attachments (Figure 2b). Fabricate an acrylic custom tray (Heraeus Kulzer) (Figure 1b) and place the custom tray on the ball abutments in the mouth; check the relationship of soft tissues.
