“…Several studies of the influence of different types of elevators on t‐SFA have indeed shown the important role of elevator design 25 . Furthermore, when the influence of PIL and GH was analyzed, it showed a linear correlation, suggesting the ability of the protruding part of the implant to assist in graft stabilization.…”

BackgroundDifferent biomaterials were suggested for sinus floor augmentation (SFA). Recently, new materials were launched showing true bone formation without remnants.PurposeThe aim of this prospective study was to evaluate an hydroxyapatite‐based, sugar cross‐linked collagen sponge (OSSIX™ Bone) in transcrestal SFA (t‐SFA).Materials and methodsTwenty‐four patients with edentulous posterior maxilla and residual bone height (RBH) >4 mm underwent t‐SFA with OSSIX™ Bone as grafting material and simultaneous implant placement. The implant Stability Quotient (ISQ) was measured by resonance frequency analysis (RFA) directly after implant insertion and at 6 months. Differences in bone height (BH) and volume were determined in CBCT and x‐rays at baseline versus 1 year of follow‐up. Graft volume was evaluated by tridimensional reconstructions. Linear regression analysis was used to evaluate the effect of bucco‐palatal sinus dimension, RBH, and length of the implant protruding (PIL) into the sinus, on the graft height (GH) changes up to 1 year, and on the graft volume at 1 year. Autocorrelation between time lag and augmented bone volume was evaluated through time series analysis correlograms. Health‐related quality‐of‐life outcomes were captured.ResultsTwenty‐two patients completed the study. The mean RBH measured at baseline was 5.81 ± 2.2 mm. The mean graft volume was 1085.8 ± 733.4 mm3. The mean GH, measured in the immediate post‐operative period, at 6 and 12 months respectively, was 7.24 mm ±1.94; 6.57 mm ± 2.30; 5.46 mm ± 2.04. The mean ISQ measured after the implant placement was 62.19 ± 8.09, and 6 months later was 76.91 ± 4.50. There was a significant correlation between buccolingual dimension and graft volume at 1 year. Neither buccolingual volume nor RBH had a significant effect on GH change, while the PIL showed a significant positive correlation (P = 0.02 and P = 0.03 at 6 and 12 months, respectively). The correlograms indicated no significant correlation, meaning that there is no tendency for graft volume to increase or decrease over time, therefore suggesting graft stability, at least up to one year of follow‐up. 86% of patients had no chewing interference.ConclusionWithin the limitations of the study, OSSIX™ Bone could be considered a valid material for SFA due to its manageability and its positive results in promoting new bone formation with long‐term stability. T‐SFA is confirmed as a less invasive and less painful method.

The procedure of crestal maxillary sinus floor elevation presents a great challenge to the field of implant dentistry. Due to the limited visualization in this procedure, the effectiveness of detaching sinus mucosa could not be assessed in real time. We recently developed an ex vivo goat sinus model by cutting the goat residual skulls along four lines determined from computerized tomography (CT) scans, extracting the maxillary premolar or molar teeth, and preparing implant socket in the maxilla. The generated ex vivo goat sinus models exposed the maxilla and the whole maxillary sinus mucosa, thus enabling real-time observation of detaching maxillary sinus mucosa via directly visualizing the working situation of sinus lift tool in the models and directly measuring the length of detached mucosa and space volume generated under the elevated sinus mucosa. One commercially available umbrella-shaped sinus lift curette was used to detach the maxillary sinus mucosa to evaluate the effectiveness of the ex vivo goat sinus models. The results showed that this curette could detach the sinus mucosa 3.75 mm in length in the mesiodistal direction and 2.81 mm in the buccal-palatal direction. Moreover, a space volume of 52.7 μl could be created under the elevated sinus mucosa in the goat ex vivo models. All the experimental results suggested that this ex vivo goat sinus model might be useful in the evaluation of improved or newly designed sinus lift tools for elevating the maxillary sinus mucosa via the crestal approach.

Management of Schneiderian membrane perforations during maxillary sinus floor augmentation with lateral approach in relation to subsequent implant survival rates: a systematic review and meta-analysis

Background This systematic review aimed to propose a treatment protocol for repairing intraoperative perforation of the Schneiderian membrane during maxillary sinus floor augmentation (MSFA) procedures with lateral window technique. In turn, to assess subsequent implant survival rates placed below repaired membranes compared with intact membranes and therefore determine whether membrane perforation constitutes a risk factor for implant survival. Material and methods This review was conducted according to PRISMA guidelines. Two independent reviewers conducted an electronic search for articles published between 2008 and April 30, 2020, in four databases: (1) The National Library of Medicine (MEDLINE/PubMed) via Ovid; (2) Web of Science (WOS); (3) SCOPUS; and (4) Cochrane Central Register of Controlled Trials (CENTRAL); also, a complementary handsearch was carried out. The Newcastle-Ottawa Quality Assessment Scale was used to assess the quality of evidence in the studies reviewed. Results Seven articles fulfilled the inclusion criteria and were analyzed. A total of 1598 sinus lift surgeries were included, allowing the placement of 3604 implants. A total of 1115 implants were placed under previously perforated and repaired membranes, obtaining a survival rate of 97.68%, while 2495 implants were placed below sinus membranes that were not damaged during surgery, obtaining a survival rate of 98.88%. The rate of Schneiderian membrane perforation shown in the systematic review was 30.6%. In the articles reviewed, the most widely used technique for repairing perforated membranes was collagen membrane repair. Conclusions Schneiderian membrane perforation during MFSA procedures with lateral approach is not a risk factor for dental implant survival (p=0.229; RR 0.977; 95% CI 0.941-1.015). The knowledge of the exact size of the membrane perforation is essential for deciding on the right treatment plan.
