Sperimentale: Coverage with PRF for Zygomatic implant placed
PRF preparation and placement: Shortly before being positioned at the surgical site, the PRF was freshly prepared.
Ten milliliters of blood were extracted from the antecubital vein and put into a test tube devoid of anticoagulant for the PRF preparation.
The blood sample was centrifuged right away for 10-12 minutes at 3000 rpm.
The PRF membrane was obtained by squeezing the fibrin clot between pieces of gauze after centrifugation

Comparatore attivo: Coverage with buccal fat pad for Zygomatic implant placed
Broad muco-periosteal dissection of the anterior maxilla and its lateral sides can easily be used to make an incision of the periosteum in the area of the wisdom teeth during implant insertion. The buccal fat pad will be dissected into the oral cavity after being enlarged with scissors. The pad can be moved forward and lower to cover the implants by gently pulling it with an atraumatic clamp. Resorbable sutures are then used to secure it to the palatal mucosa, The flap will be repositioned over the BPF and sutured to the palatine mucosa. The posterior implant typically has the easiest time achieving implant coverage. To prevent premature traction, the dissection must be done very carefully. The pad must be gradually released from its capsule in order to complete the task. It is not problematic if there are pieces of the fat pad along the crestal suture. After surgery, this will turn into the epidermis in a few days. The buccal fat pad going to be repositioned over implant body |
