Aim : To compare the efficacy of buccal fat pad (BFP) graft with sandwich graft (hydroxyapatite crystals embedded within collagen sheath) in closure of oroantral defects. Materials and Methods: A 2-year prospective study was conducted; 20 patients were included in the study were divided into two groups having 10 patients in each. Group I patients underwent surgical closure of oroantral fistula with sandwich graft and Group II patients with buccal pad of fat. Results: In Group I, the mean pain scores were 7.60 ± 0.84, 3.90 ± 1.10, 2.30 ± 1.16, 1.10 ± 0.99 and 0.40 ± 0.70 at immediate post-op., 1, 3, 6 and 12 week time intervals, respectively, whereas in Group II these were 7.30 ± 0.67, 3.50 ± 0.53, 1.70 ± 0.48, 1.00 ± 0.47 and 0.30 ± 0.48, respectively, at the corresponding time intervals. In Group I, swelling was seen to be present in 10 (100%), 7 (70%), 2 (20%) and nil (0%) patients at 1, 3, 6 and 12 weeks, respectively, whereas in Group II, it was seen to be present in 10 (100%), 10 (100%), 2 (20%) and nil (0%) patients at the corresponding time intervals. At 1 week, infection was seen to be present in 1 (10%) patient of Group I and 2 (20%) patients of Group II. At 3 and 6 weeks, infection was seen to be present in 1 (10%) patient of Group I and none of the patients of group II. No radiologic evidence of bone formation was seen in either group up to 1 week. At 3 week interval, there were 6 (60%) patients in Group I and nil (0%) in Group II showing bone formation, thus showing a statistically significant difference between the two groups. By 6 week time interval, radiologic evidence of bone formation was seen in 9 (90%) patients of Group I but in no patients of Group II, thereby showing a statistically very highly significant (P < 0.001) difference between the two groups. In Group I, in 1 (10%) patient, graft was rejected by first week; however, no further graft rejection took place. In Group II, no case of graft rejection was reported. Conclusions: The sandwich graft technique yielded a more promising closure of oroantral communication by provision of a more biologically apt base in terms of regeneration of lost bone structure at the floor of the maxillary sinus
