ABSTRACT
The osseointegration has formed the basis for today's implantology science. It is said that an implant is regarded as osseointegrated when there is no progressive relative movement between the implant and the bone with which it has direct contact. In order to preserve the interproximal dental papilla, it is important to have at least 3 mm between implants, and 1.5 mm between natural tooth and implant. Implants should be placed at a minimum of 2 mm from the inferior alveolar canal or below the maxillary sinus. Gentle surgical technique, light and intermittent drilling pressure and copious cooling irrigation are important factors to increase implant surgical success. The amount of bone needed for buccal and lingual to the implant (width) is a minimum of 1.5 mm of cortical bone. Immediate placement of implants may result in improved aesthetics through maintenance of soft tissue architecture and contours.
