What is the purpose of gingival tissue dilation?
- To prevent soft tissue injury and bleeding (correct)
- To remove the gingival tissues completely

How does tissue dilation help in impression making?
How does tissue dilation help in impression making?
- By recording tooth structure at and beyond the margins (correct)
- By protecting the supporting periodontal tissue
- By preventing the tearing of the impression material
- By ensuring a completely dry field free from blood

Study Notes
Tissue Dilation in Dentistry
- Minimum horizontal space required for proper tissue dilation is 5-6 mm.
- Purpose of gingival tissue dilation includes creating space for impression materials and enhancing visibility of margins for better fit and aesthetics.
- Tissue dilation assists in impression making by providing a more accurate representation of the dental tissues, ensuring that the final restoration fits properly.
Methods of Tissue Dilation
- The method that involves the physical displacement of free gingiva by placement of materials within the gingival sulcus is known as the "gingival retraction method."
Requirements and Indications
- A key requirement for tissue dilation is to protect and maintain the health of supporting periodontal tissues, preventing inflammation and recession.
- Tissue dilation is indicated during finishing and cementation to ensure optimal access and visualization for accurate placement of dental restorations.
