| Aim In the fabrication of complete dentures, intraoral scanners can provide a mucostatic recording of the soft tissues, but they often fail to capture the correct borders extension. Integrating conventional border molding with an intraoral scan could help overcome these scanning challenges. Methodology Ten completely edentulous patients with flabby anterior mandibular ridge were selected. All patients received a single maxillary complete denture fabricated using a muco-static impression technique opposing 2 mandibular complete dentures fabricated simultaneously using 2 different impression techniques. Group 1 utilized a conventional selective pressure impression technique, while Group 2 employed a hybrid (Digital-Physical) impression technique. the amount of soft tissue distortion between the 2 impression techniques was assessed on a digital analytical software and visual analogue scales were used to evaluate the patient’s satisfaction. Result: The comparison between both groups and between anterior flabby area and full arch were performed using Paired t test. There was insignificant difference between both impression techniques regarding deviation parameters at the anterior flabby area and the full arch at P=0.7. Patient satisfaction responses showed no statistically significant differences for both groups. Conclusion Integrating intraoral scanning with the conventional impression technique can be considered equally effective in recording flabby tissue in a mucostatic condition and producing a satisfying denture, similar to the conventional window technique. | ||||
