The Use of a Porcine Collagen Matrix for the Prevention of Buccal Bone Wall Resorption During Implant Placement in the Aesthetic Zone.

Connective Tissue Graft has been widely used around implants to increase either the thickness of the soft tissues or the width of keratinized tissues. It is considered the gold standard for soft tissue grafting. The main drawbacks are the donor morbidity and the limit amount of intraoral donor sites. In this study it will be used in the test 1 group in order to compare its clinical results with the other groups.

Collagen matrix has been used in several studies in order to evaluate its clinical properties over the last years. In this study, the graft will be placed buccally at the time of implant placement in the aesthetic zone in order to assess its clinical and radiographic properties in terms of buccal bone resorption and soft tissue augmentation. Histological assessment and Patient Reported outcomes will also be evaluated.

In the control group, the implant will be placed without any kind of soft tissue graft in order to compare this treatment modality that many clinicians apply at the clinical practice.
