Vestibular Socket Therapy (VST) Versus Partial Extraction Therapy

Vestibular Socket Therapy (VST) Versus Partial Extraction Therapy (PET) for Treating Fresh Extraction Sites With Thin Labial Plate of Bone With Immediate Implant Placement in the Esthetic Zone: A Randomized Clinical Trial

The current randomized clinical trial aimed to compare the VST versus Partial Extraction Therapy (PET) for immediate implant placement in the esthetic zone in class I fresh extraction sites.

The primary outcome was the assessment of vertical dimensional changes in peri-implant soft tissue margin.

The secondary outcome was the assessment of radiographic changes in the thickness of the facial peri-implant tissues.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: VST technique	Procedure: Class I extractions sites received immediate implants using the Vestibular Socket Therapy; A 1-cm-long vestibular access incision was made using a 15c blade 3 to 4 mm apical to the mucogingival junction at the related socket. A subperiosteal tunnel was created connecting the socket orifice and the vestibular access incision
Active Comparator: PET technique	Procedure: class I extractions sites received immediate implants using the Partial Extraction Therapy; the hopeless tooth was decoronated 1 mm coronal to the gingival margin using a diamond bur. Then, the facial root segment was separated from the rest of the root using a Lindemann bur in gentle mesiodistal sweeping strokes from the gingival margin to the apex of the root, aiming to separate the palatal and the labial root segments.
