“…Our recently published study showed that the sinus membrane lift with immediate implant placement, supporting the buccal wall as the new maxillary sinus roof, promoted satisfactory bone neoformation around the implants, which was shown after 51 months of clinical and computed tomography follow-up. 1 We agree that the Schneiderian membrane presents osteogenic potential and contributes to the process of bone regeneration, as evidenced by in vivo and in vitro studies. [2][3][4][5] We believe that the Schneiderian membrane supplies viable cells for bone regeneration, and also promotes the migration of osteogenic cells to differentiate into osteoblasts.…”

“…A broad and firm consensus has been established regarding the importance of blood clot formation, which serves as autogenous graft filler material for bone regeneration during graftless maxillary sinus lifting [15] . The results of Bassi study, after a 51-month follow-up, show that the maxillary sinus lift technique with immediate implant placement, without the use of biomaterials, may be performed with a high success rate, reducing the surgical morbidity of autogenous grafts and some of the limitations of other osteoconductive grafting materials [14] . The Silva review shows that maxillary sinus lift surgery is a safe procedure with a low complication rate and with predictable results.…”

“…It was noted that patients who had teeth present close to the sinus lift area showed higher bone formation compared to completely edentulous patients [13] . Bassi et al, in 2015, performed a study involving the installation of implants in regions of sinus lift with no graft material and observed a statistically significant difference in height between 3 and 51 months of follow-up, with an average loss of bone height of 1.57 mm [14] . Falah et al, in 2016, where Thirty graftless sinus lifting procedures were performed and 72 dental implants placed in 18 consecutive patients, using the lateral window approach.…”

Purpose: To review the literature associated with new bone formation in the maxillary sinus elevation using peripheral venous blood alone. Materials and Methods: A review of the literature was performed to record the study reference, design study, sinus lift method, number of patients, number of implants, follow up, bone gain and Perforation of sinus. A PubMed search was made from 2007 to 2017 with keywords: "sinus lift", "Peripheral Venous Blood", "new bone" and "maxillary sinus elevation". Results: 11 articles were identified and reviewed. The Lateral Window method was followed in all the studied publications. The survival rate of implants was high in all cases. A new bone is formed in most cases. Conclusion: According to our review, the application of bone graft material may not be a requirement for maxillary sinus augmentation and new bone formation with peripheral venous blood as a filler material could be an alternative treatment modality for the implant treatment.

“…After 2–3 years, it would generally reach the level same as or slightly below the implant apex [11]. In addition, such tendency for bone loss seems to be consistent in the sinus lift procedure without grafting materials [18] and might reflect the influence of physiological stimuli by implant loading and maxillary sinus ventilation [11]. Conversely, a few studies on nongrafted sinus lift procedure showed a contentious increment of intra-sinus bone volume [7, 13].…”

BackgroundSinus lift is a bone augmentation procedure that improves the alveolar crest height in an atrophic posterior maxilla. However, the regenerated bone volume can vary and generally has a tendency to decrease after sinus operation. This article describes nongrafted maxillary sinus lift using a bioresorbable unsintered hydroxyapatite combined with poly l-lactide (HA/PLLA) mesh plate device and dental implant placement in an atrophic posterior maxilla, after which continuous bone gain was observed around the implant apex during a postoperative follow-up period of 3 years.Case presentationA 60-year-old healthy female was referred to our department for dental implant therapy in the right posterior maxilla. Clinical examination revealed that the maxilla was edentulous from the right first premolar to the second molar region. Radiographically, atrophy of the maxillary alveolar ridge in the same tooth site was observed. Sinus membrane elevation and simultaneous implant placement were performed through the lateral approach. HA/PLLA mesh was utilized to maintain space under the elevated sinus membrane and as a fixation device to replace the bone window. Six months later, new bone was generated in the secluded space maintained under the elevated sinus membrane. When observed 42 months after the implant insertion, bone volume around the implant apex had increased in vertical direction under the HA/PLLA mesh plate device, and there was continuous bone formation in the sinus over time.ConclusionThis nongrafted sinus lift procedure using an HA/PLLA mesh device attained predictable bone formation. Stable membrane elevation by an HA/PLLA device might induce long-term, continuous bone formation in the sinus.
