Materials and methods. a Experimental design: scheme shows animal data and the randomization of MSA treatment with different materials homogeneity with clot or PRP. b PRP preparation and association with material/graft: (B1) whole blood collected in two sterile glass tubes containing 3.8% sodium citrate. (B2) PPP/PRP separated from red blood cells after centrifuge at 200×g (1200 rpm) for 10 min. (B3) PPP/PRP separated and transferred to a tube without anticoagulant. (B4) After centrifugation at 200×g for 15 min note the separation of PPP and platelet plug (0.5 mL). (B5) PRP added to a sterile tube containing the space filler plus 0.06 mL of 10% CaCl solution. (B6) Tube immediately transferred to water bath at 37 °C for 10 min until gelation. c Surgical procedures: (C1) AB grafts obtained by an 8-mm trephine bur. (C2) The maxillary sinus opened bilaterally using a 4-mm trephine bur. (C3) Space fillers inserted into both sinuses. (C4) Bone windows covered with collagen membrane before suturing
