“…In fact, in the present study, the healing of the augmented sinus was also achieved in the group that used cortical lamina so that the partial exclusion of the sinus mucosa from the healing bone process seems not to have affected the results. This outcome is in agreement with the results from other reports on the healing in augmented sinus in sheep and rabbits in which the sinus mucosa was excluded from the elevated space by the use of collagen membranes [28,29,30]. …”

Background: The aim of this randomized controlled clinical trial was to compare the efficacy of two different techniques for maxillary sinus augmentation using a lateral window approach: Heterologous cortical lamina without any grafting material versus 100% collagenated granular collagen porcine bone. Methods: Twenty-three healthy patients with not relevant past medical history (14 women and 9 men, non-smokers, mean age 52 years, range 48–65 years) were included. In Group I, the sinus was filled with collagen porcine bone (Geno-os, OsteoBiol, Turin, Italy) and a collagen membrane (Evolution, OsteoBiol, Turin, Italy) was used to close the lateral window of the sinus. In Group II, the sinus was treated with heterologous cortical lamina only (Lamina, OsteoBiol, Turin, Italy). Results: There was a statistically significant difference in the surgical time required to complete the augmentation procedures: 18.3 ± 2.1 min for lamina treated sites versus 12.5 ± 3.1 min for porcine bone treated sites. In Group I, the mean volume of the graft was 3101 ± 321 mm3 in the immediate postoperative examination (5–7 days), while after a six-month healing period it was 2716.7 ± 432 mm3. Conclusion: This study demonstrates that the use of heterologous cortical lamina is a valid technique for the mechanical support of sinus membranes resulting in only bone tissue formation and not mixed with the graft. The graft material was biocompatible and not completely resorbed after six months, although the remains were integrated into the bone.

“…This study confirmed that membrane presents some osteogenic potential but its effective role in sinus floor elevation is much weaker than that of the surrounding bone walls. Furthermore, a recent animal study investigating the influence of a resorbable barrier membrane placed subjacent to a pristine sinus mucosa on the healing outcome of a sinus floor elevation procedure showed that Schneiderian membrane isolation from the regeneration area did not influence the healing outcomes at all (Scala et al., ).…”

“…Based on preclinical studies investigating the role of a collagen membrane placed on the perforation as well as on a schneiderian membrane without a perforation, no potential benefit due to the placement of a collagen membrane was demonstrated (Favero et al, ; Iida et al, ; Scala et al, ). A relatively small perforation (4 × 5 mm) might, however, act as a confounding factor (Favero et al, ).…”

Objective To investigate the healing following sinus grafting in sites with a perforated schneiderian membrane repaired using a collagen membrane, compared to control sites without membrane perforation. Materials & Methods Following elevation of the sinus membrane in 16 rabbits, each sinus was assigned to one of the following groups: (a) intentional schneiderian membrane perforation, followed by the placement of a collagen membrane and bone grafting (group SMP) and (b) bone grafting without a perforation of the schneiderian membrane and without a collagen membrane placement (control group). At 2 and 4 weeks (n = 8 for each time‐point), microcomputed tomographic (micro‐CT) and histomorphometric analyses were performed. Results Overall new bone formation in group SMP was significantly delayed compared to the control group at 2 and 4 weeks (1.58 ± 1.25% vs. 9.23 ± 2.69% at 2 weeks, 10.43 ± 3.55 vs. 17.86 ± 4.11% at 4 weeks, p < 0.05). At 2 weeks, new bone formation for the areas close to lateral (1.19 ± 2.02%) and medial sinus bone walls (3.17 ± 1.98%) was markedly delayed in group SMP compared to the control group (13.08 ± 6.13% and 12.75 ± 5.63%, respectively, p < 0.05), but there was no statistical difference in those areas at 4 weeks (p > 0.05). The augmented volumes at 2 and 4 weeks were not statistically significantly different in both groups. Conclusion The perforation of the schneiderian membrane and the repair using a collagen membrane delayed new bone formation in the augmented sinuses. However, the extension of the collagen membrane on the sinus bone walls was also attributable to this delayed bone formation.
