Enhancement of dental implant stability using Saccos membrane in a sheep animal model

Abstract

Aims: The current study aimed to compare implant stability and bone density using a Concentrated Growth Factor placed before implant placement in the iliac crest of sheep. Materials and Methods: Four healthy local breed male sheep were enrolled in the study. All sheep served as two observation subgroups. The iliac crest of both sides of each sheep was operated on a random basis at one- and three-months intervals. Before each surgery, two 10 ml blood samples were drawn and immediately centrifuged in a specific centrifuge. After a cycle, the membrane was shredded into small pieces to be placed inside the surgical site before implant installation. Five standard osteotomy sites were created for the placement of five dental implants, two served as a control in which the implant was installed without additives. The other three osteotomy beds served as study groups in which shredded pieces of Sacco’s membrane were placed before implant installation. Following implant installation, dental implant stability using the Osstell Beacon device was recorded. Following animal sacrifice, bone specimens were retrieved and secondary implant stability and bone density around dental implants using Computed Tomography and Cone Beam Computed Tomography scans were measured representing one- and three-months intervals. Results: For dental implant stability, the results showed no significant differences at one-month intervals between both groups yet a statistically significant difference was disclosed at 3 months favouring the tested group. Conclusions: Within the limits of this study, it is possible to conclude that the application of CGF to the socket walls before the placement of implants may enhance the healing of bone surrounding implants, accelerate osseointegration, and offer a choice that is both convenient and affordable for implant placement.
