Clinical Outcomes of Immediate Implants With or Without a Volume-stable Collagen Matrix

Clinical Outcomes of Immediate Implants With or Without a Volume-stable Collagen Matrix: a Randomized Controlled Clinical Trial

The purpose of this study is to evaluate the soft tissue clinical results in patients that received, or not, a soft tissue augmentation around dental implant inserted immediately after the extraction.

After being informed about the study and potential risks, all patients giving written informed consent will undergo a screening period to determinate eligibility for study entry. Patients who meet eligibility requirements will be randomized in this single blinded(investigator) study.

Group (Test) will receive immediate implant after extraction and a soft tissue augmentation with a collagen matrix.

Group (Control) will receive only immediate implant after extraction without soft tissue augmentation.

Inclusion Criteria:
