This report discusses the expanded use of narrow-diameter implants ( 3.0-mm diameter) for permanent use and presents multiple clinical uses for supporting permanent restorations. The increased applications of narrow-diameter implants have expanded the options of treatment available to clinicians based on the patients' needs, desires, and limitations. The advantages, disadvantages, indications, and limitations are presented for the use of these narrow-diameter implants for permanent-case scenarios. These implants can serve as a treatment option in cases where standard-diameter implants cannot be placed due to limitations in volume or size of a planned implant site or due to financially or medically compromised patients.
