A-PRF
Conditions
Brief summary
the investigators aim from this study to evaluate platelet rich fibrin potential to heal the periodontal tissue and to form new native bone in smokers that require socket augmentation following dental extraction and before implant placement. Materials and Methods: 18 adult smoker patients with 40 extracted sockets were recruited for this study, and the extracted sockets were distributed into four different groups as follows; Group 1- A-PRF alone, Group 2- Factors-enriched bone graft matrix (commonly known as sticky bone) using autologous fibrin glue combined with an FDBA with CGF-Enriched Fibrin Membrane to covered it, Group 3- an FDBA with a crosslinked collagen membrane and Group 4-Resorbable collagen plug (RCP) alone serving as a negative control group. The patients were randomly grouped into a previously mentioned group, and the socket dimensions were measured four times, immediately after the extraction (0 days), after 10, 21, and 28 days to assess epithelial layer healing. After six months and before placing the implant fixture, both soft and hard tissue samples will be harvested to be evaluated and compared histologically, also standardized CBCT will be taken before and after extraction to evaluate the amount of mineral content and vital bone formation radiographically.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| soft tissue healing and migration. | 28 days | In all groups, the buccolingual and mesiodistal dimensions at the osseous crest of the extraction socket will be measured at the midpoints immediately after extraction with a University of Michigan O Probe with Williams marking (Hu-Friedy® Mfg Chicago, IL, USA) at 0, 10, 21, and 28 days. |
| bone height after ridge preservation. | 6 months | two different measurements shall be taken at baseline and after 6 months using Cone-beam computed tomography to asess vertical resorption measured by mean difference in length of socket. |
| bone width after ridge preservation. | 6 months | two different measurements shall be taken at baseline and after 6 months using Cone-beam computed tomography to asess the mean width ridge difference between outer border of buccal and lingual cortical plate at Socket depth at 1, 3,5 mm. |
