Brief summary

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.

Interventions

PROCEDUREClass 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

PROCEDUREclass 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.
