NCT07337837

Brief Summary

Background: Immediate implant placement has become a routine and regular clinical practice. When the labial bone plate develops a dehiscence-type defect, delayed implant placement was recommended to give suitable amount of time for soft tissue thickening. However, it has a number of drawbacks, including a lengthy treatment period, the requirement for two surgical procedures, and a potential loss of facial contour. When immediate implant is placed with flap elevation and guided bone regeneration in type II socket, labial bone augmentation results were satisfactory, but in terms of soft tissue, it led to midfacial recession and loss of soft tissue contour, resulting in a compromised final esthetic result. To reduce these drawbacks, implant can be immediately placed by vestibular socket therapy using collagen membrane. Aim of this study: To compare labial bone augmentation in immediate implant placement in type II extraction sockets by using collagen membrane placed by two different modalities.

Outcome Measures

Primary Outcomes (2)

  • change in buccal bone thickness

    CBCT will be taken for each patient and Labial bone thickness means the distance between the implant surface and the outer surface of bone

    baseline, 3 months, and 6 months

  • change in buccal bone height

    Labial bone height means the distance between the apical end of the implant (which is projected on the baseline image) and the crest of the labial bone of both images

    Baseline, 3 months, and 6 months

Secondary Outcomes (3)

  • Volumetric change of buccal soft tissue contour

    Baseline and 6 months

  • change in gingival esthetics

    Baseline and 6 months

  • chang in Modified Sulcus Bleeding Index

    Baseline and 6 months

Study Arms (2)

Study group

EXPERIMENTAL
Procedure: vestibular socket therapy

Control Group

ACTIVE COMPARATOR
Procedure: open flap surgery

Interventions

patients will undergo immediate implant placement combined with open flap surgery and labial plate augmentation.

Control Group

patients will undergo immediate implant placement and a mucoperiosteal tunnel will be made through a vestibular incision till labial orifice of the socket, a collagen membrane will be inserted under the tunnel and stabilized by membrane tacks. The space between the membrane and implant will be filled with mixture of allograft and xenograft bone material and any autogenous bone chips harvested from local surgical sites.
