What this Trial Is About
Researchers are evaluating the effectiveness of two methods for horizontal gingival displacement: a knitted cotton retraction cord and a 25% aluminum chloride gel. This study focuses on patients aged 18 to 50 years requiring fixed prostheses with at least two abutments. The goal is to compare placement time, bleeding control, patient discomfort, and the quality of the prosthesis fit using these two gingival displacement techniques. The study involves two groups of 33 patients each. One group will receive the knitted retraction cord applied with a cord picker, while the other will have the aluminum chloride gel applied to the sulcular area for 1 to 3 minutes. Impressions will be made after crown preparation with equigingival margins using a one-step putty and light body technique. Researchers will record the time needed for each method and observe hemorrhage control after air and water spray. Participants will undergo clinical and radiographic evaluation to confirm healthy gingiva and periodontium. During the study, impressions will be analyzed using a stereomicroscope and image analysis software to assess horizontal displacement. The study will measure placement time and bleeding control, with assessments conducted at baseline. The total study duration and follow-up details are not specified but include thorough observation of gingival displacement and bleeding outcomes.
