“…The patient's quality of life and psychological state also increase the difficulty of implant placement in this dental area [ 2 , 3 ]. In the past, the conventional implantation method was easy to penetrate until the mucosa of the maxillary sinus floor, resulting in the emergence of complications and affecting the surgical effect [ 4 ]. With the rapid development and progress of implant technology and medical technology, a maxillary sinus lift is widely known and used in clinics.…”

Objective. To explore and analyze the application effect of external and internal elevation of the maxillary sinus in implant restoration of the posterior maxilla. Methods. A total of 84 patients undergoing implant restoration of the posterior maxilla in the hospital were enrolled between January 2019 and March 2021. According to the random number table method, they were divided into the observation group (n = 42) and the control group (n = 42). The control group underwent external elevation of the maxillary sinus, while the observation group underwent internal elevation of the maxillary sinus. At 6 h, 12 h, and 24 h after surgery, the pain degree between the two groups was compared. All were followed up at 6 months after surgery. The osseointegration (bone resorption around implants, elevation height of maxillary sinus floor, average healing time) and soft tissues (bleeding index, plaque index, probing depth) in both groups were observed. The occurrence of postoperative complications was recorded. Results. At 6 h, 12 h, and 24 h after surgery, VAS scores in the observation group were significantly lower than those in the control group ( P < 0.05 ). At 6 months after surgery, bone resorption and elevation height of the maxillary sinus floor in the observation group were significantly higher than those i.0.0n the control group, and the average healing time was significantly shorter than that in the control group ( P < 0.05 ). The bleeding index, plaque index, and probing depth in the observation group were significantly lower than those in the control group ( P < 0.05 ). There was no significant difference in the incidence of postoperative complications between the observation group and the control group (9.52% vs. 19.05%) ( P > 0.05 ). Conclusion. The application effect of internal elevation of the maxillary sinus is good in implant restoration of the posterior maxilla, which can relieve pain and swelling and improve implant effect.

“…Dessa forma, seria possível prevenir acidentes e complicações que poderiam levar ao insucesso da técnica. (Iwanaga et al, 2019(Iwanaga et al, , 2020Stern & Green, 2012;. Além dos aspectos anatômicos, os aspectos sistêmicos do paciente também precisam serem levados em consideração, visto que a idade do paciente (>40) ou condições patológicas podem causar alterações na espessura da membrana sinusal , por isso, durante o planejamento é importante colher um histórico completo e solicitar e os exames de imagem pertinentes (Testori et al, 2019;.…”

“…A técnica foi uma abordagem de Caldwell-Luc modificada, nela são utilizados instrumentais rotatórios ou piezoeletricos na parede lateral do seio maxilar para a criação da janela óssea (Al-Dajani, 2016;Danesh-Sani et al, 2016a;Liu & Kerns, 2014; que deve ser abundantemente irrigada até que fique com uma coloração azulada (Direct, 2019), a fina parede formada deverá ser removida ou girada com cautela a fim de evitar a perfuração da membrana sinusal (Iwanaga et al, 2020;Liu & Kerns, 2014).…”

A reconstrução da região posterior de maxilas atróficas, visando a reabilitação com implantes dentários, é considerada um desafio. A cirurgia de elevação do assoalho do seio maxilar tornou-se fundamental para o ganho de altura óssea nessa região. A técnica de levantamento do seio maxilar foi descrita inicialmente em 1977 e ao longo dos anos sofreu modificações. Atualmente, diversas variações da técnica original vêm sendo utilizadas para proporcionar o acesso e permitir a elevação da membrana sinusal. No entanto, a técnica pelo acesso à janela lateral é realizada em larga escala para permitir um caminho seguro e eficiente à enxertia óssea na região. No planejamento, é crucial, a fim de evitar complicações, o conhecimento anatômico e sistêmico do paciente. A abordagem via janela lateral, consiste na confecção de uma janela óssea na parede lateral do seio maxilar, possibilitando o levantamento da membrana e a aposição de um biomaterial sob a mesma. Para obtenção do sucesso na técnica, é fundamental que o paciente apresente condições sistêmicas ideais, o profissional tenha consciência de suas indicações e contraindicações. Além disso, a escolha do biomaterial e o tempo cirúrgico para a instalação dos implantes podem ser fatores determinantes para o sucesso da cirurgia.

Computed tomography (CT), through the use of ionizing radiation, allows us to assess the different parts of the body. It is made up of an X-ray tube that rotates rapidly around the patient generating the radiation beam. This is attenuated with the patient producing information, which is collected by the detectors that are opposite to the tube located in the gantry (part of the tomography equipment); finally, these collected data are sent to the computer that will reconstruct the information obtained and will represent it as an image on the monitor. In the practice of a study, artifices or artifacts may appear regardless of their origin, which limits the scan examination; this leads to stopping the examination and starting again, and added to this with the contrast media, they have to apply these drugs again. State-of-the-art scanners allow complete reconstructions to be performed with few projections, limiting radiation doses, by means of statistical algebraic reconstruction methods. The present work shows the simulation of artifacts in sinusitis diagnosis computed tomography images, the extraction of features from each image, and an automatic classification algorithm for the differentiation of artifacts. The results show that the algorithm is able to classify the simulated artifacts with a percentage of 90%.
