“…In the consistence of what assumed by Zhu and colleagues, 20 the authors believe that the high RFA values of the small antrostomy group after 6 months, as detected by the readings of the Osstell device, attributes to the size reduction of the side window as well as its coverage with the collagen membrane, which minimized the fibrous invasion and maximized the blood supply and the osteogenic potential of the underlying constitute.…”

Background The overlying maxillary sinus frequently restrains the height of the posterior maxillary bones. Purpose Evaluating the effect of downsizing the antrostomy side‐window on the stability of the installed implants and vertical bone gain, after employing a graftless antral membrane balloon elevation (AMBE). Materials and methods The study is a randomized controlled clinical trial conducted on 20 patients with 30 deficient maxillary alveolar ridges underwent graftless (AMBE) after being allocated into a (5 mm) entry antrostomy group (the test group) and a (10 mm) entry antrostomy group (the control group) implementing a radiographic linear bone height and implant stability quotations (ISQ) comparison among both groups immediately after the placement of 38 Implants and 6 months after. Results Radiographic bone gain of the test group (5.55 ± 0.93 mm) was significantly higher than the control group (2.86 ± 0.60 mm) (p <0.001). There was no significant difference in primary stability between the test (65 ± 5.32) and control groups (62.67 ± 4.46) (p = 0.202); while the test group (73.43 ± 4.39) showed significantly higher secondary stability than the control group (64.83 ± 6.05) (p <0.001). ISQ values recorded at 6 months were significantly higher than those recorded at insertion in the test group (p <0.001), while they were insignificant in the control group (p = 0.148). Conclusion Undersizing the antrostomy window deemed beneficial concerning the vertical bone gain and the simultaneously placed root form dental implants' secondary stability.

“…We have introduced a modified beagle model for maxillary sinus floor augmentation via a 5mm‐diameter mini‐lateral window with simultaneous implant placement in 2018 (Zhu et al., 2018). This model is established on the maxillary recess of dog, which is only seemed as a sinus equivalent due to the absence of the Schneiderian membrane and pneumatization (Wetzel et al., 1995).…”

Objective To investigate the early bone formation in beagles with mini‐lateral window sinus floor elevation and simultaneous implant placement. Material and methods Six beagles were selected for the split‐mouth design procedures. In each animal, one maxillary recess received a 5 mm‐diameter mini‐round lateral osteotomy (test group), and the contralateral maxillary recess received a large rectangular osteotomy (10 mm long and 8 mm wide), (control group). Simultaneous implant installation was executed on bilateral maxillary recesses. Tetracycline and calcein dyes were administered on the 14th, 13th days and the 4th, 3rd days prior to sacrifice, respectively. After 8 weeks of healing, the beagles were euthanized for fluorescent labeling and histomorphometric analyses. Results In both groups, new bone formation initiated from the circumferential native bone of the maxillary recesses and extended toward the central sub‐recess cavities. The maxillary recesses with the mini‐window procedures exhibited superior mineral apposition rate, bone formation rate, and the percentage of new bone area to those of the group exposed to large osteotomy procedure (p < .05). While there was no significant difference in the value of bone‐to‐implant contact, the mini‐window group displayed a tendency for an increase in this aspect (p > .05). Bone formation rate and new bone amount were not statistically correlated with bone‐to‐implant contact (p > .05). Conclusion The hypothesis that mini‐lateral window sinus floor elevation with simultaneous implant placement would improve early new bone formation in augmented sinus compared with large lateral window procedure is accepted.

Background The lateral maxillary sinus augmentation (MSA) procedure has good predictability in terms of the success of bone regeneration with a low incidence of postoperative infections, estimated between 2% and 5.6%. Although the use of antibiotics is an established and standardized prophylactic measure for MSA procedures, the addition of corticosteroids still varies among clinician preference and clinical judgment. Purpose The aim of this systematic review was to identify whether the administration of corticosteroids during the MSA surgical procedure affects postoperative symptoms including swelling, pain, and infection rate. Materials and methods A literature search through PubMed, EMBASE, Ovid MEDLINE, and Web of Science indices, according to PICO criteria, was conducted to identify whether MSA peri‐operative use of corticosteroids reduces the incidence of complications and patient morbidity. A single arm meta‐analysis was performed due to the lack of randomized controlled trials (RCTs) comparing groups treated with or without peri‐operative corticosteroids. The intracluster correlation co‐efficient (ICC) and design effect were calculated to adjust for the clustering design. Results In the 37 studies included, a total of 1599 patients (378 Cort, 1221 No‐Cort) were analyzed. Before and after taking account of clustering, there was statistically significant effect of corticosteroids on swelling, pain, wound dehiscence, trismus, and hematoma. The complication rates postoperatively were comparable between the two study groups, however slight differences existed in the incidence of active suppuration (1.7% [95% CI 0.7–3.9] Cort vs. 3.2% [2.2–4.5] No‐Cort), wound dehiscence (3.9% [1.3–11.2] Cort vs. 2.1% [1.0–4.1] No‐Cort) and trismus (2.7% [0.8–8.4] Cort vs. 1.4% [0.8–2.5] No‐Cort). Conclusions Although the event rate of the 1‐to‐2‐week postoperative complications did not differ between the two groups, the lack of conclusive data and research comparing peri‐operative corticosteroid use makes it impossible to draw definitive conclusions and more evidence and studies designed for this specific purpose are needed.
