Implant procedure	Single sitting surgical procedure and very often flapless (no open surgical procedures are necessary). Implant procedures are less time consuming than that required for bridgework.	Single sitting surgical procedure and very often flapless (no open surgical procedures are necessary). Implant procedures are less time consuming than that required for bridgework.	Very often more complex surgical procedures are necessary, spread over 2 or 3 sittings in a period of 3 - 6 months (Implant placement, Healing Screw placement & Abutment Placement).
Armamentarium	Simple—the implant surgery kit is very simple with very few instruments	Simple—the implant surgery kit is very simple with very few instruments	Complex—a wide array of instruments are required for placement of two piece implants
