N/A Patients who need implant placement after tooth extraction. Intervention 1: Intervention group: Patients who are candidates for implant placement in the posterior area of the lower jaw 4 months after tooth extraction without dental socket preservation surgery intervention. Intervention 2: Intervention group: Patients who need socket preservation technique after tooth extraction and are from Xenograft material. It will be used for placement in the socket and after 4 months they will refer for placement of the implant. Intervention 3: Intervention group: Patients who need a socket preservation technique after tooth extraction and Alograft material will be used for placement in the socket and 4 months later they will refer for implant placement.
