Patient Satisfaction and Bone Gain Following Autogenous Particulate Sticky Bone Preparation With Xenograft Versus Without Xenograft for Grafting of Maxillary Anterior Knife-edge Ridge in Partially Edentulous Patients for Implant Placement

Modern Dentistry aims to restore what is missing, no matter what the difficulty is. As many patients have lost their teeth to a number of factors, either trauma or disease or lack of care. Now the individuals are seeking to restore the function and esthetics. The more the number of teeth is missing along with ridge deficiencies can present serious challenges to the clinician.

Implant supported prosthesis is an attractive option for restoring edentulous or partially edentulous patients. However, extensive loss of the alveolar bone is a complex problem that faces many surgeons. This era has witnessed numerous trials and research for bone augmentation for the defective alveolar ridge. The goal is to create sufficient space for endosseous implant placement in a knife edge ridge.

Alveolar bone resorption occurs in either a horizontal or vertical direction. It can also be composite. There are 3 classes of bone-grafting materials based upon the mode of action. Autogenous bone is an organic material and forms bone by osteogenesis, osteoinduction, and osteoconduction.

Allografts such as demineralized freeze-dried bone are osteoinductive and osteoconductive and may be cortical and/or trabecular in nature.

Alloplasts such as hydroxyapatite and tricalcium phosphate may be synthetic or natural, vary in size, and are only osteoconductive. They can be divided into three types based upon the porosity of the product and include dense, macroporous, and microporous materials. In addition, alloplastic materials may be crystalline or amorphous. These materials have different properties and therefore indications.
