“…measured series of grey values to analyze bone formation in BO grafts. 39 BO granules, however, exhibit a relatively high absorption of X-rays, which is consistent with the present study. Since BO granules and newly formed bone tissue exhibited low contrast in images, the grey values of BO and new bone could only be measured together.…”

“…Since BO granules and newly formed bone tissue exhibited low contrast in images, the grey values of BO and new bone could only be measured together. 39 However, this procedure needs extensive calculation, which makes it less intuitive in the clinic. In the NS-Sponge group, the mineralization process inside the scaffold was manifested as a gradually extending opaque area in CBCT images, which was different from the high-density radiographs in the BO-Collagen group.…”

The search for bone substitutes that are biodegradable, ensure space maintenance, and have osteogenic predictability, is ongoing in the field of sinus augmentation. We thus compared the bone regeneration potential of nanostructured sponges (NS-Sponge) with that of collagen-stabilized inorganic bovine bones (BO-Collagen), gelatin sponges (Gelatin), and blood clots (Cont) in sinus augmentation of rabbits. NS-Sponge was prepared by thermally induced phase separation with porogen leaching techniques. All the materials were non-hemolytic and cytocompatible. The porous and nanofibrous NS-Sponge showed better dimensional stability to support cell growth and osteogenic differentiation. In vivo, the sinus membrane collapsed in Cont and Gelatin, while BO-Collagen and NS-Sponge maintained the elevated height as assessed by come-beam computed tomography. Limited bone regeneration was observed in Cont and Gelatin. In the entire implanted area, histological analysis revealed a higher percentage of new bone area at 4 weeks of BO-Collagen treatment; however, a significantly greater increase in new bone area was observed after 12 weeks of NS-Sponge treatment. The 12-week remnant NS-Sponge material was significantly lower than the 4-week remnant material. Overall, NS-Sponge may be highly recommended for sinus augmentation, as it exhibits numerous advantages, including excellent operability, clear imaging characteristics, space maintenance, biodegradability, and superior osteogenic potential.

“…The study by Kwon et al (2019) performed the evaluation of 33 patients who underwent surgery to raise the sinus membrane using the transcrestal technique. Six months after the intervention, it was observed that the height of the patients' maxillary sinus varied between 7.88 mm to 21.63 mm, with an average residual bone height of 4.38 mm.…”

Diante da atrofia maxilar, o assoalho do seio tende a apresentar apenas uma fina parede óssea cortical, impondo limitações para a colocação de implantes dentários. O objetivo desta revisão de literatura foi avaliar o desempenho sobre a importância da elevação do seio maxilar para a instalação de implantes dentários. Foi realizada uma revisão da literatura nas bases de dados PubMed / Medline, Scielo e Science direct. Os artigos publicados entre 2014 e 2020 foram selecionados com base nos seguintes critérios de inclusão: disponibilidade do texto completo, publicação em inglês e clareza nos detalhes metodológicos utilizados. Estudos têm demonstrado que a anatomia do seio maxilar deve ser investigada antes do planejamento dos implantes na região posterior da maxila, a fim de diagnosticar a presença de patologias sinusais, a presença de septos e pneumatização. É importante ressaltar que a elevação do seio maxilar é um procedimento que apresenta bons resultados, apresentando poucas complicações no pós-operatório. Além disso, a tomografia computadorizada de feixe cônico deve ser o exame de imagem de primeira escolha quando este procedimento for indicado para a instalação de implantes dentários.

“…There have been a few studies reported graft volume after different types of sinus surgeries. [30][31][32][33] However, this is the first CBCT study in the literature using the current software to investigating the safe volume of the sinus cavity for the grafting. The safe volume after sinus grafting means not to interfere with the osteomeatal unit that hazardous to sinus physiology.…”

THREE-DIMENSIONAL CALCULATION OF SINUS AUGMENTATION VOLUME AFTER MAXILLARY SINUS FLOOR ELEVATION ABSTRACT Objective: This study aimed to calculate the volume of the maxillary sinus and grafted part of it with different modes of three-dimensional reconstruction software. Materials and Methods: This retrospective volumetric cone-beam computed tomography study was carried out on 21 patients/ 36 maxillary sinuses who had undergone maxillary sinus lift surgery using a lateral approach, between 2010 and 2016 at the Department Periodontology. All statistical analyses were performed by using the NCSS (Number Cruncher Statistical System, Kaysville, Utah, U.S.A.) software. P values <0.05 were considered to indicate statistical significance. Results:The mean volume of the right maxillary sinus cavity was 15.37 cm³ while for the left it was 15.90 cm³. There was no statistically significant difference between right and left maxillary sinus volumes (p>0.05). An occupied portion of the sinus cavity after lateral sinus floor elevation surgery was approximately 14.87 %. Furthermore, the volume through manual and automatical modes of the software do not affect the results (p>0.05). The right and left sides of the maxillary sinus volumes were not different from each other. Gender and measuring mode was not found to be related to volumetric values of the maxillary sinus cavity. Conclusions:The grafted volume of the sinus cavity was defined as a safe volume in terms of serious complications during and after the surgery.
