“…The treatment of edentulous posterior maxilla with implant supported rehabilitation may result difficult for the insufficient bone volume in consequence of buccolingual and/or apical occlusal atrophy of the edentulous alveolar crestal bone and pneumatization of the maxillary sinus. In this anatomical condition, the implant primary stability can be very difficult to obtain in absence of a useful quantity of cortical bone and for the loose structure of type IV spongious bone which prevents the fixture migration into the sinus [1,2]. Many different surgical techniques have been developed to treat the atrophic posterior maxilla.…”

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.

“…Treatments using endoscopes preserve the sinus epithelium and unstop the ostium obliterated by chronic inflammation [21]. However, this alternative is not commonly indicated because it requires specific equipment and training and also extensive opening for sinus manipulation and object removal [22].…”

A variety of surgical techniques have been developed to reconstruct the posterior maxilla when bone volume is insufficient. A barrier membrane or bone window pushed inside the sinus cavity as the ''roof'' of the sinus cavity for preserve the space and help bone. The heterologous cortical lamina is used for the mechanical support, without any grafting material, of sinus membranes resulting in only bone tissue formation and not mixed with the graft.

Removal of a migrated dental implant from the maxillary sinus after 7 years: a case report

Abstract: Postoperative recovery was uneventful. To the author's best knowledge, this case represents the first report concerning migration of an oral implant into the maxillary sinus removed after 7 years.
