الناشر والمؤلف كتاب REMOVABLE ORTHODONTIC APPLIANCES .
Platelet-rich fibrin (PRF) substance is a by-product of blood (plasma) that is rich in platelets. PRF, in short, is simply a byproduct of blood. It is exceptionally high in platelets and growth factors, the “signaling” molecules that allow communication between cells. PRF is a tool that significantly improves bone and soft tissue regeneration. Recently, its use has been advocated for regenerative periodontics and wound healing.
Platelet-rich fibrin is the new thing when it comes to surgery, with improved healing and immune support. The operation can have a faster and better recovery, with fewer post-operative complications. The application of platelet-rich fibrin during the implantation process enhanced the stability of the implants. The application of platelet-rich fibrin improves the stability of the implant in the first week of osseointegration. The biggest advantage of using platelet-rich fibrin is its complete absorption, thus avoiding the time of the second surgery, which is definitely a critical factor in elderly patients. This appears to be a minimally invasive technique with low risk and satisfactory clinical outcomes such as preventing complications or implant failure especially in age-related elderly patients.

وصف الكتاب

Removable orthodontics appliances refers to those devices that can be inserted into and removed from the oral cavity by the patient will .
First fixed appliance prototype, 1728. Historically, the development of the fixed appliances preceded that of removable appliances. Pierre Fauchard, father of modem dentistry, in his 2-volume opus entitled, ‘The Surgeon Dentist’ published in 1728 described the bandeau, an expansion arch consisting of a horseshoe-shaped strip of precious metal to which the teeth were ligated. This fixed appliance tied to the teeth became the basis for Angle’s E-arch.
Removable appliance, 1836. A German dentist “Friedrich Christoph Kneisel (1797-1847) was first to use plaster models to record malocclusion in 1836 and use chin strap for his prognathic patients which perhaps was the first removable orthodontic appliance. He also used a removable plate quite similar to the one used nowadays . Further evolution of the removable appliances was linked to the development of the process of rubber vulcanization.
