Clinical Trial Summary

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.

Description:

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%

Intervention

Procedure:
• Alveolar ridge augmentation with injectable platelets rich fibrin
Injectable platelets rich fibrin is added to xenograft for alveolar ridge augmentation in order to preserve bone and decrease bone resorption
• Alveolar ridge augmentation with hyaluronic acid
Hyaluronic is added to xenograft for alveolar ridge augmentation in order to preserve bone and decrease bone resorption
• Alveolar ridge augmentation with xenograft
Xenograft is added alone as a active compatator

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Radiographic bone width	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.	4 months postoperative
Secondary	histological and histomorphometric assessment	The biopsy samples were harvested and processed. All samples were serially sectioned using a microtome. Slides were stained separately with hematoxylin and eosin and observed using a light microscope. For histological evaluation and histomorphometric analysis, 20 photomicrographs from different sections taken at every 200 µm of each biopsy sample were captured at original magnification 10×, 20×, and 40× using a digital camera. The image analyzer was calibrated to automatically convert the measurement units (pixels) produced by the image analyzer program into actual micrometer units. Data from the sections of each group were averaged.	4 months postoperative
