Buccal fat pad versus sandwich graft for treatment of oroantral defects: A comparison

Abstract

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

Oro antral fistula closure using sandwich technique

“…The findings were similar to the finding of study of (Hariram, U S Pal et al 2010) [10] . No evidence of infection was seen in any patients at first week but infection was observed in 2 (8.3%) patients from second follow up till the final follow up visit.…”

Surgical Management of Oro-Antral Communications Using Resorbable GTR Membrane and FDMB Sandwich Technique: A Clinical Study

“…None of the patients had bleeding from the socket, loss of graft, signs of sinusitis or infection or wound gaping. This finding is agreeable to the study conducted by Hariram and Mohammad [11]. Radiological evidence of bone formation was seen after 4 months of graft placement.…”

“…and length of extracted socket varied from 10 to 17 mm (average 12.93 mm, SD-2.92 mm). These sizes are close to the sample utilized for comparative study conducted by Hariram and Mohammad [11]. The loss of sulcus depth in our method was an average of 3.1 mm SD:1.2 mm.…”

“…Однако при этом как правило не проис-ходит восстановления костной ткани в области аль-веолярного отростка [3]. В доступной литературе отсутствуют убедительные данные о том, насколько часто и полноценно происходит восстановление костной ткани после устранения ороантрального сообщения с использованием перемещенного сли-зисто-надкостничного лоскута [4].…”
