Clinical Trial Summary

After tooth extraction, the alveolar process undergoes substantial horizontal and vertical resorption specifically in non-molar sites, where horizontal, vertical mid- facial, and mid-lingual ridge reduction could occur . These dimensional changes are clinically relevant, as they may affect dental implant placement and compromise soft tissue aesthetics.

Alveolar ridge preservation (ARP) is based on the application of a bone replacement graft into the extraction socket & collagen membrane/plug. Recent systematic reviews have shown that ARP may limit bone resorption to about 50% of what is normally observed in case of unassisted healing . This finding indicates that ARP is effective; but at the same time, it underlines the potential for improvement.

Description:

In ARP procedures based on socket grafting, the use of a bone replacement graft would prevent up to a 30% of volume reduction in the coronal third. Whereas it has limited effect in the remaining middle-apical thirds . Since grafting of the alveolus often results in the persistence of residual graft particles embedded into the newly formed bone with a delay in the rate of bone deposition and mineralization the need to extend the grafting procedure apical to the coronal third of the socket seems questionable. Based on these considerations, a novel, simplified technique, namely, the Biologically-oriented Alveolar Ridge Preservation (BARP) for ARP that restricts socket grafting to the coronal portion of the socket was presented .

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Horizontal radiographic changes in bone dimensions	Horizontal measurements will be performed perpendicular and parallel to the tooth axis, respectively. The level of the palatal bone crest preoperatively will be used as a reference line (level 0). The horizontal dimension of the alveolar process will be registered at 1, 3, and 5 mm apical to this reference line (level 1, 3, and 5). After performing all measurements on the CBCT (T1), the software switched to the superimposed image (T4) so that the measurements could be performed while using the same reference levels. Finally, changes in bone dimensions will be calculated by subtracting bone dimensions at T4 from that at T1.	4 months
Secondary	Vertical radiographic changes in bone dimensions	Vertical measurement will be performed by measuring the height of buccal (B) and palatal (p) bone plates from the apical end of the socket to the coronal level of the socket.	4 months
Secondary	Changes of soft tissue height at the buccal , lingual & central aspects of the site.	Since soft tissues will be separated from hard tissues by using lip retractors and a backward position of the tongue, soft tissue height could be assessed on CBCT images. Changes in soft tissue height will be calculated by subtracting soft tissue height at T4 from that at T1	4 months
