“…According to their records, mucosal thickening showed the highest percentage. [9,15] In agreement with Hammuda A.A. and Ghoneim M.M., [16] who conducted a study on patients having chronic sinusitis with the criteria of Category 2 that showed insignificant difference between the groups. The results of the current study also revealed no significant difference between the two groups in the average gained bone height, that was 7.24 ± 1.45 mm and 7.23 ± 1.78 mm, in groups I and II respectively.…”

Background: Chronic sinusitis can be considered as a relative contraindication for sinus lifting procedure. Sinus lining with 6:9 mm radiographic thickening with or without partial sinus obliteration, is contraindicated for sinus lifting. Patients and Methods: A prospective comparative clinical study was carried out to evaluate the impact of chronic sinusitis on sinus lifting procedures regarding bone height and infection. Pre-operative and 6-months post-operative CBCT of 12 maxillary sinuses which underwent sinus lifting procedure with grafting and simultaneous implant placement (20 dental implants), were done to evaluate the average gained bone height. Two groups of 6 sinuses each; Group I included patients with healthy sinuses, whereas Group II included patients with chronic sinusitis ( identified by the presence of Schneiderian membrane thickening > 6 mm). Also, clinical follow-up was done to report the occurrence of any infection. Results: Statistically, there was no significant difference in average bone gain between the two groups with very small effect size; in group I: it was 7.241.45± and in group II: it was 7.231.78±. Regarding infection, there was no sinus infection in group I compared to one sinus with one implant (that was lost) in group II showed sinus infection three months postoperatively. Conclusion: Chronic sinusitis with a thickening of Schneiderian membrane > 6 mm may not be considered as a contraindication for sinus lifting with grafting and simultaneous implant placement.

“…In addition, trauma caused by surgical trauma and heat generation in the preparation of the cave will lead to the appearance of an inflammatory response, which in turn induces the activation of osteoclasts and promotes bone resorption [ 17 , 18 ]. At the same time, because the bone will cause bone resorption after being squeezed to a certain extent, the vertical height of the bone will be reduced, and when the implant is implanted for repair, the surrounding bone will be tighter and the bone resorption will be further increased [ 19 ]. In addition, the results of this study showed that the bleeding index, plaque index, and probing depth of the observation group were significantly lower than those of the control group ( P < 0.05), suggesting that maxillary sinus lift was more helpful for the reconstruction of periodontal tissue in patients with implant restoration in the maxillary posterior region, reducing the damage to periodontal tissue.…”

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.

Background/Objectives: To evaluate incidental findings in the mandible after the placement of dental implants using a new cone-beam computed tomography (CBCT) software. Methods: The initial sample consisted of 2,872 CBCT scans of patients of both sexes. The parameters evaluated in this study were the location of the implants in the mandible, implant length, anatomical relationship of the implant with the mandibular canal, presence or absence of damage to the adjacent teeth, presence or absence of implant fractures, and presence or absence of bone support. Fisher's exact test was performed to compare the variables. The significance level was set at p = 0.05. Results: Out of 2,872 CBCT scans, 214 images of patients with an average age of 44.5 years were included. The most frequent location of the implants was the posterior region (93.5%), with 54% of the implants having a length between 9 and 14 mm. It was found that 92% of the implants were positioned above the mandibular canal. Three damage to adjacent teeth was observed, with no correlation with the implant positioning (p = 0.999). In 100% of cases of implants in the anterior region, there was bone support. Fracture was observed in 1.7% of implants with a length between 9- and 14-mm. Conclusions: The installation of implants in the mandible occurs more frequently in the posterior region, with a high presence of bone support and a low incidence of damage to adjacent teeth, anatomical structures, and fractures.
