Elevation of the maxillary sinus membrane for de-novo bone formation: First results of a prospective study in humans

Does intraoperative perforation of Schneiderian membrane during sinus lift surgery causes an increased the risk of implants failure?: A systematic review and meta regression analysis

“…At this stage of the analysis, 42 studies were excluded because they did not meet inclusion criteria. Finally, a total of 58 studies met the inclusion criteria and were processed for critical review …”

“…A total of 2947 patient enrolled in 58 studies (35 RCTs and 23 unrandomized studies) . A total of 7358 implants were installed in posterior atrophic maxillae following 3884 SFE, either via lateral approach ( n = 3438) or crestal ( n = 446). The follow‐up time was varied from 4 months to 5 years.…”

“… The follow‐up time was varied from 4 months to 5 years. A total of 859 lateral approach were performed using piezosurgical in nine studies or rotary burs ( n = 2541) . Crestal sinus lift were performed using osteotome according to summer technique in 14 studies .…”

“…For RCTs, 19 studies had a low risk of bias, nine studies an unclear risk of bias and seven studies a high risk of bias . More detailed about risk of bias assessment according to Cochrane, an assessments tool for the RCTs is presented in the Supporting Information Figure S1.…”

The Use of Poly-d,l-lactic Acid (PDLLA) Devices for Bone Augmentation Techniques: A Systematic Review

“…In their study titled “Elevation of the Maxillary Sinus Membrane for De Novo Bone Formation: First Results of a Prospective Study in Humans” [ 43 ], Lie et al (2015) used PDLLA membranes to perform an elevation of the maxillary sinus membrane. The aim of this study was the clinical and histological investigation of bone regeneration and integration of a well characterized inorganic bovine bone substitute material (Bio-Oss™; Geistlich Biomaterials GmbH, Wolhusen, Switzerland) mixed with autogenous bone in comparison to elevation of the sinus membrane alone.…”
