Ever since modern dental implants were introduced, more than 40 years ago, the development of the ideal implant has been a major research subject in the field. The conventional Crystal implants are indicated when an adequate vertical and horizontal bone is available and the process does not require any augmentation procedures. Augmentation procedures tend to increase risks and cost of dental implant treatment. Extensive research to minimize the use of such procedures & better understanding of implant interactions has led to the development of advanced concepts involving unconventional implants. With an immense literary jargon available regarding such implants, this book provides comprehensive insight about these unconventional implants.
