Summary

The aim of this study is to evaluate wound healing after the application of the Tooth Collar Technique (TCT) for bone augmentation in the upper or lower jaw. This technique is designed to promote tension-free wound closure and to reduce the risk of wound dehiscence. Augmentation is performed under local anesthesia. The gingiva is opened according to the TCT, after which the bone defect is reconstructed with standard biomaterials and covered with a membrane. No experimental materials are used- only a modified incision technique.

Conditions

  • Insufficient Bone Volume Prior to Implant Surgery

Interventions

PROCEDURE

Tooth Collar Technique

During surgery, the gingiva will be opened using tooth collar technique instead of standard flap designs; after which the bone defect is augmented using standard biomaterials and covered with a membrane.
