The Effect Of Hyaluronic Acid And Melatonin With Systemic Administration of Vitamin C On Implant Stability After Immediate Implant Placement in Anterior and Premolar Region in Systemically Healthy Patients

The concept of immediate implant placement at the time of tooth extraction was first introduced by Schulte et al. on animal studies. Since then, many follow-up studies examining different variables have supported the concept of immediate implant placement. pioneered a major contribution to immediate implant placement in human studies which recommended the insertion of an implant into a fresh extraction socket.

They advocated immediate implant placement primarily to reduce the number of surgical interventions needed to perform an implant-supported rehabilitation and shorten the treatment time.

Placement of implants immediately into extraction sites allow the surgeon to idealize the position of the implant appropriately with a better rehabilitation of the normal contour to the facial aspect of the final restoration.

Immediate implant placement in fresh extraction sockets was reported to reduce alveolar bone resorption. Better esthetic outcomes were achieved including the prosthetic crown length in harmony with the adjacent teeth, natural scalloping and easier distinct papillae to achieve and maximum soft tissue support.

Hyaluronic acid is a glycosaminoglycan, this unique molecule is implicated In a variety of biological functions including structural integrity, and the regulation of embryologic development. It is described as a natural organic substance, with physiological therapy activity, main component of the extracellular matrix of many tissues such as the skin, synovial joints and periodontal tissues .
