Differences between Braided and Knitted Retraction Dental Cords
- The main difference between braided and knitted retraction dental cords lies in their construction and properties, which affect their performance in dentistry 1, 2.
- Braided cords are more commonly used and have been shown to be effective in achieving gingival retraction, with some studies suggesting that they are more effective in displacing gingival tissues than knitted cords 1, 3.
- Knitted cords, on the other hand, may be less effective in displacing gingival tissues, but they can be less traumatic to the gingiva and provide better hemostasis control 4.
- The choice between braided and knitted cords may depend on the specific clinical situation, with braided cords being more suitable for cases where more significant gingival displacement is required, and knitted cords being more suitable for cases where minimal retraction is needed 4.
Clinical Performance of Braided and Knitted Cords
- Studies have shown that braided cords can provide better impression qualities, with easier insertion, proper dilatation, and less recurrent bleeding 1.
- However, knitted cords may be more comfortable for patients and easier to use for operators, with some studies suggesting that they can provide better hemostasis control and less tissue displacement 4.
- The clinical performance of both braided and knitted cords can be affected by factors such as cord thickness, medicament, and soaking time 1, 2.
Factors Affecting the Choice of Retraction Cord
- The choice of retraction cord can be influenced by factors such as the type of preparation finish line, the depth of the subgingival margin, and the type of gingival tissue 3, 4.
- Impregnated gingival cords may be more effective on thick gingival tissue, while paste systems may be more effective when minimal retraction is required for hemostasis control, preservation of the gingiva, and less tissue displacement 4.
