Abstract Background To compare a sinus augmentation procedure with a distal displacement of the anterior wall to a standard sinus lifting and grafting with a lateral window approach. Methods In the displacement group, a sinus surgical fracture results in the distal displacement of the anterior wall by means of an electromagnetic device. In the filling group, a sinus lifting with lateral access and grafting with particulate bone was performed. Bone volume beneath the maxillary sinus was investigated with Computerized Tomography after data superimposition. Clinical and radiological outcomes over 3 years had been evaluated. Results Forty-three dental implants were enrolled. The surgery of both groups significantly increased the bone volume in the VOIs (p-value≤0.0017) respectively for displacement group from 1.17±0.34cc to 1.53±0.39cc with a final bone volume gain of +0.36±0.17cc and for filling group from 1.24±0.41cc to 1.94±0.68cc with a bone augmentation of 0.71±0.31cc. Two implants early failed in the filling group, attesting the 3-year survival rate to 92.6%(CI95%: 82.7%-100%). Marginal bone loss at the distal aspect was 1.66±0.72mm and 1.25±0.78mm for displacement and filling group, respectively (p-value=0.0497). Conclusions The study showed an effective bone gain around dental implants at 3-year of survey both for sinus augmented by backward displacement of the anterior wall (+34%) and by sinus lifting with a lateral window approach (+57%).

Sinus Lifting

The insertion of dental implants in atrophy maxilla is a complicated issue because no bone support due to expansionof maxillary sinus and atrophy of maxillary ridge alveolar. Surgery by sinus lifting with autogenous bonetransplantation has been proven to be an acceptable treatment to get bone support. The lateral window techniqueand transalveolar osteotomy sinus lifting are the methods to correct the height of inadequate bone in the posteriorarea of maxilla for preparation of implan dental insertion. Technique of transalveolar osteotomy sinus lifting isnoninvasive compared to lateral window sinus lifting technique.

Maxillary Sinus Floor Elevation

Research oriented to bone regeneration and reconstruction has been growing and national and international research teams have complied with the development of sustained and sustainable research criteria. The aim of this work is to present the results of investigations realized by different centers to which the author is affiliated, making an analysis of maxillary sinus reconstruction for dental implants. We revised research during the last 6 years related to the surgical technique, anatomical analyses, and definition, as well as choice of bone graft. We determined the main conclusions of the analyses, innovative research to optimize efficiency in major sinus reconstruction was established, as was the technique modification for different cases.

Increased Risk

Preoperative evaluation of maxillary sinus anatomy is very important to avoid surgical complications due to close anatomical relations between the sinus and the posterior maxillary teeth and/or edentulous alveolar ridge. Posterior superior alveolar artery is a branch of the maxillary artery and provides the vascularization of the lateral sinus wall and underlying mucosa. Maxillary artery branches should be taken into consideration during sinus lifting procedures and bone augmentation due to increased risk of bleeding by damaging the artery during the osteotomy. Computed tomography (CT) explores three-dimensional anatomic structures and provides complex and accurate information about them. Cone Beam Computed Tomography (CBCT) offers an accurate view of the teeth and surrounding structures at high resolution, despite low-dose radiation used. In this study, the incidence of anatomical variations and sinus pathology were assessed using CBCT. The aim is to evaluate the presence of sinus pathology (sinus mucosal thickening, oro-antral communications, sinus tumors, cysts, polyps), presence and position of the posterior superior alveolar artery. These issues are important because they are about the limits of the dental implants in the posterior maxillary area. The presence of sinus pathology and anatomical variations may predispose to complications and even failures of implantation therapy.

Points Of View

Background: Due to the lack of data comparing the biological behavior of two formulations, granules and paste, of alloplastic graft from microtomographic and histomorphometric points of view, the aim of the present experiment was to compare the histomorphometric and microtomographic healing of two formulations, i.e., granules (MR sites) or paste (MR-inject sites) of an alloplastic graft composed of a combination of beta-tricalcium phosphate and hydroxyapatite used for maxillary sinus lifting. Methods: A sinus lifting procedure was carried out bilaterally in 20 rabbits, and the elevated space was filled with either paste or granules of an alloplastic material. A collagen membrane was placed on the antrostomy and the animals were euthanized after 2 or 10 weeks, 10 animals each group. Microtomographic and histological analyses were performed. Results: Higher proportions of new bone formation were found at the MR, compared to the MR-inject sites both after 2 weeks (2.65 ± 2.89% vs. 0.08 ± 0.12%; p < 0.01) and 10 weeks of healing (34.20 ± 13.86 vs. 23.28 ± 10.35%; p = 0.022). Conclusions: It was concluded that new bone formation was faster in the MR sites, compared to the MR-inject. However, a longer time of healing should be allowed to make final conclusions about the efficiency in bone formation of the paste formulation of the biomaterial used in the present study.

Abstract Background The presence of septa increases the risk of Schneiderian membrane perforation during sinus lift procedure, and therefore, the chance of graft failure increases. We present a safe method of managing septa and, in particular, overcoming small and palatally located septa. Methods After the elevation of the flap and the creation of a small bony window positioned anterior to the septum, the Schneiderian membrane is lifted carefully. A thin and narrow osteotome is then placed at the indentation created at the base of the septum, and mobilization of the septum is achieved by gentle malleting. The membrane is again carefully lifted up behind the septum. Results There was one small membrane perforation case in all 16 cases, and none of these patients showed postoperative complications such as implant failure, infection, or maxillary sinusitis. Conclusions This technique is useful for overcoming the problem of maxillary sinus septa hindering the sinus floor elevation procedure, leading to fewer complications.
