open sinus lift is used to augment the maxillary sinus prior to implant Placement in patients with sinus pneumatization due to early extraction of upper molars Where the remaining available bone length is from zero to 6 mm which will not accommodate for implant placement and not sufficient for implant initial stability so we will need to do Sinus lift and augmentation of the sinus with various bone grafts either (alloplast, allograft, Autogenous). Search is conducted electronically on line in pub med & Cochrane and manual Search was also done from 2007 to 2018 the articles included assisting &evaluating various types of bone substitute used in open sinus lift surgeries.197 papers are identified through data base searching 37 Additional records identified through manual search, after duplication removal the remaining papers are 187,187 paper were reviewed&152 were excluded by title &abstract, 35 article were reviewed as full text, 27 articles were excluded by reason, 8 articles were included in this study, Eight included articles have revealed new bone formation with percentage ranges from 48%as the highest percentage&16.4 as the lowest percentage, residual material ranges from 6.3%to 34.8% which differs according to type of bone graft used, histological evaluation is performed in 7 articles in addition to radiological evaluation only one article used radiographic evaluation only This systematic review supported the fact that bone substitute act as a scaffold for new bone formation with different percentages according to type of bone substitute used.

Objectives:Maxillary sinus pneumatization and extraction of posterior maxillary teeth are among the most common factors attributing to the diminished alveolar process. Implants placed in posterior region of maxilla showed the highest failure rates due to poor bone density in addition to insufficient remaining bone volume needed for implant primary stability.Materials and methods:Ten patients were selected from out patient clinic with partially or fully edentulous maxilla missing premolars or molars with residual alveolar bone height less than 6 mm, both groups received open sinus lift surgery with different grafting material group 1 (control group) received hydroxyapatite (HA)in a disc form, group 2(Study group) received silica calcium phosphate nano-composite (SCPC) in a disc form. Clinical evaluation, Cone Beam Computerized Tomography (CBCT) (Pre-operative, 0 & 4 months post-operatively),Scanning Electron Microscopy (SEM) (4 months post-operatively) and histological study (4 months post-operatively)were performed for both groups as follow-up following either stages of surgery.Results:all patients had uneventful wound healing, and none experienced excessive post surgical edema.Following surgical stage II (implant placement) all patients exhibited proper dental implant osseointegration,and all were properly restored by fixed prosthodontics. For radio graphical results the bone height and bone width showed statistically significant increase in both groups; The histopathological results of both groups revealed new bone formation in the histological sections attained from the core bone biopsies over 4 months post operatively. While the analysis of the SEM images revealed that in the control group (HA), the new bone exhibited an irregular and porous appearance In the study group (SCPC), the bone appeared as a continuous plate with nearly homogenous surface.Conclusion:within the limitations of the present study, the present data support the fact that both HA and SCPC can be used, successfully, in sinus augmentation procedures. Moreover, the suggested technique in combination with grafts in the form of discs, and using piezoelectric surgical units are simpler and safer approaches to lateral sinus lift augmentation procedures.
