3.1 Impression-taking

Impressions for the final restoration are usually taken about 6-8 weeks after suture removal. Depending on the posi­tion of the restoration and your personal preference, the impres­sion can be taken with a closed- or open- tray method. Bite registration and color assessment are also part of this treatment step and allow you to provide the required information to your dental technician to fabricate the final restoration.
