简要总结
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.

结局指标
主要结局
change in buccal bone thickness
时间窗: baseline, 3 months, and 6 months
CBCT will be taken for each patient and Labial bone thickness means the distance between the implant surface and the outer surface of bone
change in buccal bone height
时间窗: Baseline, 3 months, and 6 months
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
次要结局
- 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)
