In selected cases, it is possible to insert an implant and a prosthetic crown at the same time: this is the so-called immediate loading approach. This protocol is usually used in completely edentulous patients, when the fixtures are splinted together by means of bars supporting the prostheses. In cases of single implants in esthetic regions, only in very rare cases it is possible to use this technique and the prosthetic crown will not have any occlusal contact during chewing but it will be used only for esthetic and phonetic purposes.: this is the so-called immediate provisionalization approach. To do immediate loading/provisionalization, it is mandatory that the implants have excellent primary stability after the surgical intervention. However, it is usually advisable to use a delayed loading protocol after a healing period of 2-5 months.
