“…The data are even more limited since all 8 studies were published by two University groups only (University of Düsseldorf, University of Zurich). Based on available data, radiographic marginal bone level changes appear to be minimal and well in line with data on implants being placed in native bone (Benic, Bernasconi, Jung, & Hammerle, ). Clinical outcome measures such as PD, PI and the stability of the mucosal margin were stable.…”

Objectives To analyse the evidence regarding the efficacy of lateral bone augmentation procedures in terms of defect resolution in cases of horizontal ridge deficiencies after implant placement. Materials and Methods Included studies met the following inclusion criteria: randomized controlled trials (RCTs) or controlled clinical trials (CCTs), re‐entry procedure to assess defect resolution, minimum of 10 patients (5 per group). Meta‐analyses were performed whenever possible, including subgroup analysis based on membranes and grafting materials. Results Twenty‐eight publications (20 short‐term, 8 follow‐up studies) were included. The most often used type of intervention was a xenogeneic particulated grafting material (XE) and a resorbable collagen membrane (CM). The mean defect height at baseline amounted to 5.1 mm (range 2.4–7.8) and decreased to a mean of 0.9 mm (range 0.2–2.2) at re‐entry, and the mean defect resolution was 81.3% (range 56.4%–97.1%). Defect height reduction was not significantly different using CM+XE as control treatment compared to the combined data of the respective test groups [n = 11; weighted mean difference (WMD) = −0.006 mm; 95% CI, −0.61, 0.60; p = 0.985]. The absence of any lateral bone augmentation was less favourable than the conjunction of a membrane and a bone grafting material (n = 1; MD = −1.96 mm; 95% CI, −3.48, −0.44; p = 0.011). The lack of a grafting material was less favourable than the conjunction of grafting material and membrane (n = 1; MD = −2.44 mm; 95% CI, −4.53, −0.35; p = 0.022), and the addition of a membrane compared to a grafting material alone was more favourable (n = 3; WMD = 0.97 mm; 95% CI, 0.31, 1.64; p = 0.004). Conclusions Lateral bone augmentation is a successful treatment modality. For optimal defect height reduction, a barrier membrane and a grafting material should be combined.

“…More predictable results have been obtained with horizontal bone augmentation (Donos, Mardas, & Chadha, ; Kuchler & von Arx, ). In addition, similar clinical and radiological results have been reported for implants placed with bone augmentation compared with those completely placed into pristine bone (Benic, Bernasconi, Jung, & Hämmerle, ).…”

“…Sinus floor augmentation has also shown greater marginal bone loss in the first year (Galindo‐Moreno, Fernández‐Jiménez, Avila‐Ortiz, et al, ). The type of augmentation material and protocols can differently influence bone loss (Benic, Bernasconi, Jung, & Hämmerle, ; Schwarz, Schmucker, & Becker, ). Bone loss was lower in bone substitute grafted or untreated sites but increased in sites treated with membranes (Zambon et al, ).…”

Objectives To perform an exploratory analysis of factors influencing annual rates of peri‐implant marginal bone loss (RBL) calculated over different time frames, at implants unaffected by peri‐implantitis. Material and methods A total of 154 implants from 86 patients were reviewed at 1.6–6.8 years after placement. Marginal bone levels (MBL) were assessed on intraoral radiographs at three time‐points: immediately post‐placement, time of loading, and least 1‐year post‐loading. RBLs (mm/year) were computed using these three time frames and corresponding MBL changes as: RBL placement‐loading, RBL loading‐review, RBL placement‐review. Exploratory ordination of three RBLs, corresponding time durations, and 17 background factors were used for visualization. Hierarchical linear mixed‐effects models (MEM) with predictor selection were applied to RBL outcomes. The correlation of actual MBL with MBLs predicted by RBL placement‐loading and RBL loading‐review was tested. Results Median RBL placement‐loading was 0.9 mm/year (IQR = 2.02), loading‐review was 0.06 mm/year (IQR = 0.16), and overall RBL placement‐review was 0.21 mm/year (IQR = 0.33). Among‐patient variance was highest for RBL placement‐loading (SD = 0.66). Longer time predicted lower RBL in all time frames. Shorter time of loading significantly predicted lower RBL placement‐review. Augmentation predicted lower RBL placement‐loading, while anterior location and older age predicted lower RBLs placement‐loading placement‐review. Only MBL projected using RBL placement‐loading significantly correlated with actual MBL. Conclusions Exploratory analysis indicated RBL varied with the time duration used for calculation in pre‐ and post‐loading, and overall periods. In each period, RBL declined with increasing time. Earlier loading predicted lower overall RBL. Higher pre‐loading RBL predicted worse actual bone level.
