“…This result is in agreement with several reviews in the literature (Moraschini, Uzeda, Sartoretto, & Calasans‐Maia, 2017; Nasr, Slot, Bahaa, Dorfer, & Fawzy El‐Sayed, 2016; Yang, Xia, Wang, Cheng, & Shi, 2019). A recent review compared seven clinical studies using TSFE with and without graft material (Chen & Shi, 2018).…”

Aim To evaluate the effects of (a) transcrestal sinus‐floor elevation (TSFE) and (b) residual bone height on long‐term implant survival. Materials and Methods Chi‐squared and t tests were used for descriptive comparison of the groups. Kaplan–Meier survival curves and corresponding log‐rank tests were used to investigate implant survival over time. Multivariable Cox regressions were performed for the total population and experimental group. Results A total of 634 patients received 648 implants with TSFE, while 674 implants without TSFE served as controls. Thirty implant failures occurred in the experimental group and 28 in the control group. Ten‐year Kaplan–Meier survival curves for the 157 implants (24.3%) still under observation showed a probability of survival of 93.7% for the implants with TSFE and 92.9% for the 72 implants without TSFE (p = .678). The probability of 10‐year survival of all implants in the experimental group decreased to 77.4% for implants placed in residual bone heights of 1–3 mm, compared with 95.7% for implant sites with bone heights of 4–6 mm and 97.6% for bone heights of >6 mm. Conclusions Transcrestal sinus‐floor elevation has no negative effect on the long‐term implant survival. Membrane perforation or negligible bone height, however, reduces the probability of 10‐year survival.

“…However, in a more recent report, the crestal approach was applied with only 2 mm of alveolar bone available [ 13 ]. Sinus augmentation has been performed without graft materials, and a previous study reported no significant difference in short-term implant survival in maxillary sinus augmentation with versus without grafts [ 14 ]. The application of short implants may minimize complications.…”

Background and objectives: The average rate of chronic sinusitis after maxillary implantation was approximately 5.1%. However, the evidence of predictive risk factors for sinusitis after implantation is lacking. The aim of this study was to perform an anatomic study on the maxillary sinus mucosal thickness (MSMT), the distance between the maxillary sinus ostium and sinus floor (MOD), and the MSMT/MOD ratio as a preoperative risk indicator for sinusitis after maxillary dental implantation. Materials and Methods: Between October 2008 and October 2019, all patients referred to the otolaryngology department were included in this study. A total of 120 patients were enrolled. The 95 patients who received no treatment prior to implantation were classified into Group A, the 16 patients who used antibiotics before implantation were classified into Group B, and the patients who had implants inserted after functional endoscopic sinus surgery were classified into Group C. The MSMT, MOD, MSMT/MOD ratio, anatomical factors associated with ostial obstruction, and the occurrence of postoperative sinusitis were reviewed. Results: There were significant group differences in MSMT (Group A vs. Group B, p = 0.001; Group B vs. Group C, p = 0.003; Group C vs. Group A, p < 0.0001). The MOD showed no significant difference among the three groups. The MSMT/MOD ratio showed significant differences between Groups A and B (p = 0.001), B and C (p < 0.0001), and C and A (p < 0.0001). Conclusions: It is important to check not only the proportion of the maxillary sinus occupying lesion, but also the status of the maxillary sinus osteomeatal complex when making therapeutic decisions. In addition, collaboration between dentists and otolaryngologists could improve outcomes in patients with maxillary sinus lesions.

“…Similar long-term outcomes of Astra bone-level implants have been reported with retrospective design (Caban et al, 2017). Recent systematic reviews reported that the short-term and mid-term implant survival rates ranged from 93.5% to 100.0% (Duan et al, 2017;Yang et al, 2019). However, none of the previous studies have reported long-term outcomes of patients with severely atrophic maxilla (residual bone height [RBH] ≤4 mm).…”

Objective: The aim of the present study was to report 10-year results of osteotome sinus floor elevation (OSFE) without grafting severely atrophic maxilla (residual bone height ≤4 mm). Materials and Methods: Patients undergoing OSFE without grafting and implant placement were included for 10-year examinations. Implant survival, complicationfree survival, modified bleeding index (mBI), modified plaque index (mPI), pocket probing depth (PPD), peri-implant marginal bone loss (MBL), endo-sinus bone gain (ESBG) and mean cost of recurrence were evaluated. Results: Overall, 23 patients with 35 implants attended 10-year examination. Cemented implant crowns or implant-supported fixed dental prostheses were delivered to the patients. Kaplan-Meier implant survival was 89.2% at implant level and 84.1% at patient level. Complication-free survival was 26.0% at patient level and 37.0% at implant level. The average complication-free survival time was 74.6 months (95% CI: 63.2-86.0 months) at implant level and 69.1 months (95% CI: 54.8-83.4 months) at patient level. The mBI, mPI, PPD, MBL and ESBG at 10-year follow-up were 0.91 ± 0.58, 0.48 ± 0.51, 2.94 ± 0.79 mm, 1.63 ± 0.83 mm and 2.72 ± 0.51 mm, respectively. The cost of managing recurrence was 43.6% of the initial cost of treatment. Conclusion: The results of the present study indicate that OSFE without grafting is a reliable treatment option in severely atrophic maxilla. Acceptable survival rate, stable MBL and ESBG could be achieved within 10 years. Low complication-free survival and high costs of recurrence management need to be considered.
