Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Test group: localized ridge defects were augmented using autologous fat grafting Control group: localized ridge defects were augmented using conventional subepithelial connective tissue graft.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Autologous fat grafting
Autologous fat grafting
A fat graft will be aspirated from the abdomen under local anaesthesia and processed using the Microfat grafting technique. Afterwards the fat graft will be injected in the previously created pouch at the recipient site. Then the pouch will be closed using interrupted sutures 5-0 vicryl.
Sub-epithelial connective tissue graft
Sub-epithelial connective tissue graft
A subepithelial connective tissue graft of a size that corresponds to that of the defect will be harvested from the palate using the trap door technique. The donor site will be closed using cross horizontal sling sutures and interrupted sutures 4-0 vicryl. Subsequently, the graft will be inserted in the previously created pouch at the recipient site and secured to the flap using vicryl sutures 5-0. Then the pouch will be closed using interrupted sutures.
