“…Among them two Zygoma implants. The overall implant loss rate after All‐on‐4 operations with or without Zygoma implants thus was in agreement with the values published by other authors (Aboul‐Hosn Centenero, Lazaro, Giralt‐Hernando, & Hernandez‐Alfaro, ; Lopes et al, ; Malo, Araujo Nobre, Ferro, & Parreira, ; Malo et al, ; Pesce, Pera, Bruno, & Menini, ).…”

Objectives The purpose of the study was to assess patients' postoperative discomfort after implantations according to the All‐on‐4 concept with and without using Zygoma implants. Material and methods Three treatment groups were formed for this prospective study: All‐on‐4 rehabilitation in the maxilla (group 1, N = 25), All‐on‐4 rehabilitation in the maxilla using at least two Zygoma implants (group 2, N = 25), and All‐on‐4 rehabilitation in the mandible (group 3, N = 20). Principal outcome parameters were postoperative pain (100 mm VAS) and perceived swelling (100 mm VAS). Also, the use of analgesics was documented. Results The worst postoperative pain of 21.3 (SD 18.9) VAS was observed in group 2, but there was no statistically significant difference between the groups (mixed ANOVA p = .791). The postoperative total intake of painkillers was significantly higher in group 2 than in the other groups (p < .001). On postoperative day 28, the mean pain scores in all groups declined to values below 5 VAS. Postoperative perceived swelling in group 2 was significantly more severe than it was in group 1 and 3 (p < .001). Conclusions The use of Zygoma implants in All‐on‐4 surgical interventions had an essential effect on postoperative swelling, but less so on postoperative pain. The slightly increased, but statistically not significantly different postoperative pain in group 2 was compensated by an overall higher postoperative intake of painkillers compared to the other groups.

“…The recent meta-analysis reports a survival rate of 98.35% for the follow-up of 6 to 12 months [3], while the systematic review on immediately loaded zygomatic implants reports survival rate range of 96%-100% [16]. Another recent meta-analysis, comparing quad zygomas to two zygomatic implants with fixtures from the same manufacturer as the study implant, reports an overall survival rate of 98.0% [17].…”

“…Consequently, most of the patients were provided with a fixed provisional prosthesis, which dramatically shortened time-to-teeth, especially when combined with the fact that no bone grafting was performed prior to or simultaneous with the surgery. The immediate loading of the implants, as performed in this study, is a valuable treatment option because it offers the patient an immediate restoration of function, esthetics, and social confidence [17,22]. In some of the study patients, the provisional acrylic prosthesis served as the final prosthesis, after a realignment at 4 to 6 months after the surgery.…”

The main objective of this analysis was to evaluate (1) implant survival, (2) biologic complications, and (3) demographics associated with zygomatic implants placed according to the zygomatic anatomy-guided approach (ZAGA). This retrospective multicenter study reviewed data from the charts of 82 consecutive patients who had received 182 zygomatic implants. Patients were fully edentulous (62.2%), partially edentulous (22.0%), or had failing dentition (15.9%). Most patients (87.5%) did not have previous sinusitis and 11.3% had been previously treated for it. Additionally, about half of the patients (53.8%) did not present periodontal pathology, and one-third (36.3%) did, but were subsequently treated. Most implants (93.8%) were loaded immediately, i.e., within 48 h of placement. Implants were followed for 10.5 ± 7.2 months, and all were recorded as surviving and stable at last follow-up. Post-operative complications were infrequent and included sinusitis (10.1%) and peri-implant hyperplasia (0.8%). The low complication rate and 100% implant survival and stability indicate that zygomatic implants offer a viable treatment option when performing graftless restoration of severely resorbed maxilla, including immediate loading protocols.

Background Zygomatic implants are a treatment option for severely atrophic maxilla. Main text This study aimed to summarize and evaluate systematic reviews assessing the clinical outcomes of zygomatic implants including survival/failure rate and complications. PubMed-MEDLINE, Google Scholar, LILACS, and the Cochrane Database were searched up to April 2020. Risk of bias assessment was conducted by the AMSTAR tool. Initial searches yielded 175 studies. These were assessed, and following title abstract and full-text evaluation, 7 studies (2 meta-analyses) were included in the final review. According to the AMSTAR tool, 1 was deemed high quality, 4 were classified as medium, and 2 as low quality. The mean AMSTAR score (±SD) was 5.28 of 9 (±2.36) ranging from 2/9 to 9/9. The reported survival rates ranged from 95.2 to 100% except for resected maxillas, which established higher failure rates up to 21.43%. Concerning the complications with the zygomatic implants, various surgical and prosthetic complications were reported with sinusitis being the most frequently observed complication. Zygomatic implants appears to offer a promising alternative to formal bone grafting techniques with lower costs, less complications, less morbidity, shorter treatment times, and comparably high survival rates. Conclusion Complications were rare and usually easy to manage. However, the treatment should be directed by appropriately trained clinicians with noticeable surgical experience.
