The techniques of immediate loading in the edentulous mandibular arch nowadays have relatively minor risk factors if this rehabilitation is performed according to the guidelines shared by literature and widely used by dentists.
On the other hand, the surgical techniques for crest expansion and localised sinus lift allow, according to the author, minimising surgical trauma, and the post-operative course and to obtain faster healing times compared to other surgical techniques, even though today these depend on the surgeon’s skills. Nevertheless, in cases like the present one, the sum of several risk factors requires extreme accuracy and attention in the pre-operative planning phase, in the programming of the final prosthetic structure and its completion. This study proposes combining the crestal expansion technique with the immediate loading technique.
The surgical techniques used in performing this total bi-maxillary rehabilitation allow resolving the implant-prosthetic problem in impaired anatomic situations that could otherwise only be treated by guided bone regeneration techniques or bone grafts or other more invasive surgical procedures. Those proposals are safe with comparable results in terms of prognosis as well as of efficacy and can be associated, at least in the lower arch, to immediate loading.
