The use of DBB/CF reduced the magnitude of vertical bone resorption , yet the study showed high risk of bias .
Implication s of Key Findings Within the limitations of this systematic review , L-PRF reduced the magnitude of vertical and horizontal bone resorption , which places L-PRF as a potential material of choice for ridge preservation procedures .
Conclusions Within the limitations and weaknesses of both studies , the use of DBB/CF prevented the vertical crestal bone resorption while the L-PRF prevented both the horizontal and vertical crestal bone resorption .
Background The purpose of this systematic review was to accurately assess the procedural success of  ridge preservation technique  through the application of strict inclusion and exclusion criteria .
Pressure Bearing Device Affects Extraction Socket Remodeling of Maxillary Anterior Tooth. A Prospective Clinical Trial
BACKGROUND Extraction socket remodeling and ridge preservation strategies have been extensively explored . PURPOSE To evaluate the efficacy of applying a micro-titanium stent as a pressure bearing device on extraction socket remodeling of maxillary anterior tooth . MATERIAL S AND METHODS Twenty-four patients with a extraction socket of maxillary incisor were treated with spontaneous healing ( control group ) or by applying a micro-titanium stent as a facial pressure bearing device over the facial bone wall ( test group ) . Two virtual models obtained from cone beam computed tomography data before extraction and 4 months after healing were 3-dimenionally superimposed . Facial bone wall resorption , extraction socket remodeling features and ridge width preservation rate were determined and compared between the groups . RESULTS Thin facial bone wall result ed in marked resorption in both groups . The greatest palatal shifting distance of facial bone located at the coronal level in the control group , but middle level in the test group . Compared with the original extraction socket , 87.61 ± 5.88 % ridge width was preserved in the test group and 55.09 ± 14.46 % in the control group . CONCLUSIONS Due to the facial pressure bearing property , the rigid micro-titanium stent might preserve the ridge width and alter the resorption features of extraction socket
