In the last years, scientific research stated that immediate loading is a reliable and predictable treatment if it is performed under standard protocols.
INTRODUCTION
Nowadays, implantology is a predictable area and well-accepted by scientific community for missing or doubtful prognosis tooth reposition. More than 30 years ago, Brånemark and col. published the first articles that presented implantology as a safe and predictable method to rehabilitate edentulous patients (Brånemark et al. 1977; Brånemark 1983; Adell et al. 1981; Albrektsson et al. 1981) if a rigid protocol is performed, in which one of the key factors were the time the implant was submerged until loading (3 months for the jaw and 6 months to the maxilla).
The evolution of implantology, since the establishment of the rigid protocols published during the “development phase” of implantology (Cochran 2006) till nowadays, had been constant, and the loading protocols changed through clinical trials that were developed, that promoted the development of new surgical techniques and the improvement on implant surface, led to the demonstration that the success of an implant is not time dependent on how long it is submerged but it is dependent on the almost absence of micromovements during the osseointegration phase (Szmukler-Moncler et al. 2000; Isidor 2006). The micromovements during osseointegration should be less than a limit between 50 µm to 150 µm (Szmukler-Moncler et al. 2000) for rough surfaces and approximately 100 µm for machined surfaces (Brunski 1992), from which it would produce fiber integration of the implant.
