简要总结
The present clinical trial will try to demonstrate the efficacy of stable xenogeneic collagen matrix in maintaining the vestibular coronal soft tissue volume and the stabilization of mid-buccal margin position in immediate post-extraccion sockets compared with the use of autogenous connective tissue grafts.

结局指标
主要结局
Analyze the volumetric dimensional changes between the test and the control group
时间窗: At T12 (12 months after extraction).
Analyze the volumetric dimensional changes between the test (xenogeneic collagen matrix) and the control group (autogenous connective tissue graft) in mm3.
次要结局
- Analyze the mid-vestibular gingival level of the treated tooth.(At T12 (12 months after extraction).)
- Measure the band of keratinized tissue around the treated tooth(At T12 (12 months after extraction).)
- Assessment of pain during surgery in both groups(After 10 days after surgery)
- Quantification of the analgesic medication intake by patients in both groups(At 10 days after the surgery.)
- Comparison of the total surgical time used in each group.(At the day of the surgery)
- Comparison of the economic costs for each patient in the collection of the autologous graft and its application versus the purchase of the Fibrogide and its application.(At the day of the surgery)
- Analyze patient satisfaction between groups(At T12 (12 months after the extraction).)
- Analysis of possible complications in both groups.(They will be reported anytime during the study)
- Evaluation of implant success in both groups at one year of follow-up(At T12 (12 months after the extraction))
