简要总结
Thirty-six patients (19 females and 17 males) that required implant placement in esthetic zone participated in this study and were blindly allocated 12 patients per group, all patients had ARP either with I-PRF with xenograft, HA with xenograft or xenograft alone, the sockets were sealed with free gingival graft harvested from the palate.
详细描述
The aim of this study was to compare injectable platelets rich fibrin (I-PRF) versus hyaluronic acid (HA) in combination with xenografts for ARP. Methods: Thirty-six patients (19 females and 17 males) that required implant placement in esthetic zone participated in this study and were blindly allocated 12 patients per group, all patients had ARP either with I-PRF with xenograft, HA with xenograft or xenograft alone, the sockets were sealed with free gingival graft harvested from the palate. The assessment was done by cone beam CT preoperative and 4 months postoperative to assess radiographic bone gain and crestal bone loss. Clinical parameters were soft tissue thickness, keratinized gingiva and clinical bone width that were assessed preoperative, 4 months and 1 year postoperative. Histological assessment of core bone biopsies 4 months postoperatively was performed by histomorphometric analysis of newly formed bone %, mature bone% and residual graft%

研究组 & 干预措施
Injectable platelets rich fibrin
Injectable platelets rich fibrin was prepared where 10 ml of patient venous blood was centrifuged without anti-coagulants (plain plastic glass-coated) at 700 rpm speed for only 3 minutes, xenograft was mixed with I-PRF to make sticky bone, sticky bone was placed into extraction socket till the socket was fully filled up to the gingival margin
干预措施: Alveolar ridge augmentation with injectable platelets rich fibrin (Procedure)
Hyaluronic acid
Hyaluronic acid (HA) syringe containing 1 mL of cross-linked hyaluronic at a concentration of 20 mg/ml in a saline phosphate buffer solution at sterilized content was used. HA was mixed with particulate xenograft 1:10 ratio to form a putty consistency for condensation and was placed into extraction socket till the socket was fully filled up to the gingival margin
干预措施: Alveolar ridge augmentation with hyaluronic acid (Procedure)
Xenograft
Xenograft was mixed with saline, placed in extraction socket till the socket is fully filled up to the gingival margin
干预措施: Alveolar ridge augmentation with xenograft (Procedure)
结局指标
主要结局
Radiographic bone width
时间窗: 4 months postoperative
Cone beam CT (CBCT) were obtained preoperatively and 4 months postoperatively. The radiographs were analyzed using One- Viewer viewing software (iCATVision). The buccolingual width was measured into different levels. At the bone crest (A), 3mm from the bone crest (B) and 6 mm from the bone crest (C). For standardization in the sagittal slice, the axial plane was adjusted to pass through the cemento enamel junction (CEJ) of the adjacent teeth. On the axial slice, the mesiodistal dimension from the distal surface to mesial surface of the adjeceent teeth was measured. The coronal plane was adjusted to be pass through the middle of the distance in order to be perpendicular to both buccal and lingual cortices. Measurement were all performed on the coronal slices. In addition, fusion was done by superimposing preoperative and 4 months CBCT in all groups.
次要结局
