Inclusion criteria

Inclusion criteria: The patient has a full coverage treatment plan, or a full crown or tooth-supported bridge. The gingiva should be in a healthy state without swelling, bleeding, or resorption. The tooth in question should not have plaque. Patients with blood diseases who use anticoagulants and blood pressure medications are not included in this study. (Basically without systemic disease) The distance between the gingival margin and the finish line must not exceed 0.5mm. The tooth is probed at four points: mesifacial, mediofacial, dystofacial, and palatal or lingual, and at no point should it be deeper than 1 or 1.5 mm.

Exclusion criteria

Exclusion criteria: The patient has an unrelated treatment plan. Patient has Gingival diseases (swelling,bleeding). The tooth in question has calculus and plaque. The patient has systemic disease. The distance between the gingival margin and finish line is more than 0.5mm.

Design outcomes

Primary

MeasureTime frame
The accuracy of recording the finish line. Timepoint: Recording the finish line using 3 molds (without gingiva retractor, with gingiva retractor , and with Iranian paste based on aluminum chloride). Method of measurement: Scanning and overlapping images.;Observing gingival bleeding. Timepoint: observing bleeding during or after taking impression. Method of measurement: observing.;Checking the amount of pain. Timepoint: checking the amount of pain during or after taking impression. Method of measurement: Visual Analogue Scale.
