“…The procedure investigated in this study was also performed in the implant sites with a ABH less than 3 mm, even if the initial implant stability was not optimum in all cases, so the minimum recommended ABH was 3 mm for this study. Most publications on vertical bone gain in sinus transcrestal elevation reported an average of less than 5 mm (19). The amount of bone gain reported with TGSL technique used in this study was 6.4 ± 1.6 millimeters and this gain was maintained for all 3 years of radiographic examinations.…”

“…Subsequently, various modifications to the original technique have been performed in order to improve the reliability and safety, such as: the introduction of the osteotome for the sinus lift (17), the osteotome for positioning of bone (37) and the use of a balloon catheter for the membrane lifting (38)(39)(40)(41). Fractures or perforation of the sinus floor are the main complications related to the transcrestal approach with technique of osteotomes (14,16,17) and drills with (18,19) or without (15) depth stop; the limitations of this surgical approach are represented by: impossibility of a direct visualization of the sinus cavity and of the Schneider membrane, limited amount of bone increase and high risk of accidental perforation of the membrane, without the possibility of surgical repair than the lateral approach. In patients with severely maxillary bone resorption is recommended a conventional approach with surgical lateral window because of perceived limitations with the transcrestal approach (42).…”

“…The severely atrophic maxilla is still a challenge, many clinical approaches have been recommended to increase the amount of available bone (12)(13)(14). Schneider's membrane elevation can be achieved through a lateral (15) or transcrestal (8) surgical approach to increase the residual subantral bone (15)(16)(17)(18)(19). The bone grafts regeneration of maxillary atrophies and of the sinus floor is a proven long-term option of treatment (20)(21)(22)(23)(24); however, patients may refuse such procedure for the invasiveness of the technique, the increased time of healing and additional costs.…”

SUMMARYPurpose. This study describes the ability to perform a technique for bone regeneration in maxillary posterior deficit (TGSL) without the use of bone grafting materials using a highly minimally invasive protocol. Materials and methods. Sixty six implants have been inserted in the sinus floor of a total of 39 patients through the transcrestal guided sinus lift technique (TGSL). All patients have been followed for at least three years in function. The drilling protocol was adapted on the basis of bone density of each implant site to achieve a torque between 45 and 55 Ncm. Healing titanium abutments tightened to 35 Ncm have been used. A CAD/CAM metal ceramics final prosthetic restoration has been generated a six months after the tissues healing and the provisional functionalization of the occlusion. Survival rate of implants and prostheses, biological and biomechanical complications, changes in marginal bone levels, and total height of alveolar crest bone before and after surgery have been evaluate and measured by the results obtained in this prospective study. It was also measured the periodontal parameters as well as levels of perception of pain by the patient during the entire recovery period.Results. The result of the data of follow-up was 41.96 (24 to 36) months. Cumulative implant survival was 98.53% at 3 years. There were no biological and mechanical complications and there were no prosthetic failures during the whole period of follow-up. The Marginal Bone Loss (MBL) average during the first year of operation was from 0.33 to 0.36 mm, while the 3-year follow-up, the MBL average was 0.51 to 0.29 mm. The average of residual bone height of alveolar ridge before treatment was 6.7 to 1.6 mm (range 5.1 to 9.2 mm), while the average bone height was gained 6,4 -1.6 mm (range 3.2 to 8.1 mm). All patients reported lower pain levels and found to have normal periodontal parameters. Conclusions. This study suggests that the use of guided surgery to perform transcrestal maxillary sinus lift to increase the sub-antral crestal height is a minimally invasive technique of success for the short and medium-term of follow-up, thus avoiding the extended treatment time and reducing the morbidity associated with the lifting of the floor of the maxillary sinus with traditional technique using bone grafting materials. Furthermore, this protocol without the use of graft materials does not vary the final outcome that have demonstrated the presence of newly formed bone around implants offering always predictable results, and giving a further reduction in the costs of the procedure rehabilitation.

“…[8,11,24,25] As regards the sinus floor elevation effect of AOT, it is clear that the amount of vertical bone gain was smaller than that reported in other studies, where transcrestal sinus floor elevation was achieved by means of osteotomes and burs plus autogenous bone and graft biomaterial (6.75 mm), [26] osteotomes plus deproteinized bovine bone mineral (DBBM) (6.9 mm) [27] or osteotomes and burs plus synthetic hydroxyapatite or DBBM (7.70 and 6.50 mm, respectively). [28] However, the majority of studies where sinus elevation was performed by means of the use of osteotomes alone or combinations of osteotomes and burs, with or without graft material, reported a mean vertical bone gain lower than 5 mm. [29À37] AOT makes it possible to minimize the risk of intraoperative and postoperative complications, creating an adequate implant site for the placement of a conventional-sized implant.…”

“…[25]. The smart lift technique research has demonstrated the biomaterial used in association with it, may provide a predictable elevation of the maxillary sinus floor along with limited post-surgical complications and postoperative pain/discomfort [26]. Thus, Smart Lift technique represents a minimally-invasive surgical option for sinus floor elevation aimed at preventing surgical complications [20].…”

Background: In the rehabilitation of atrophic posterior maxilla, factors such as age, extraction of teeth result in loss of alveolar bone height together with increased pneumatization of sinus contradicting the implant surgery. Although adequate bone height can be achieved using various maxillary sinus augmentation techniques, these procedures have been practiced successfully. However, significant complications occur such as perforations or tearing. To maintain the integrity of Schneiderian membrane subsequently increasing the success rate a retrospective analysis is carried out on various techniques with complications which occur during and after treatment.Methods: A systematic online and manual review of the literature identified articles dealing with SFE. Applying rigid inclusion criteria, screening and data abstraction were performed independently by two reviewers. The follow-up of was a minimum of 6 months. The articles selected were carefully read and data of interest were tabulated. The identified articles were analyzed regarding implant outcome, with or without graft using different surgical techniques with complication rates using random-effects Poisson regression models to obtain summary estimates/ year proportions. This article reviews various sinus lift techniques for intact elevation of Schneiderian membrane based on advanced PUBMED, Medline, Cochrane database system search of English-language literature from the year 2004 to present in order to compare and evaluate the success rate with minimal complications selecting the most suitable which can fulfill the criteria of being non-invasive, less time-consuming, more reliable and less traumatic.Result:After reviewing various sinus elevation techniques; nasal suction technique(NaSucT), balloon antral elevation technique(BAOSFE), and Hydraulic Sinus Lift technique(HySiLift) emerges as more favourable among all these and can efficiently lift the Schneiderian membrane with minimal trauma. We must emphasize that these are new techniques and cannot replace the conventional techniques as a whole.
