However, the patient presented with transverse deficiency of the premaxilla (Figure 1).

Selection of mini-implants (Figure 2): two mini-implants, both of similar geometry, self-tapping and self-drilling, made of titanium alloy with dimensions of 1.6 mm diameter and 10 mm length (Morelli, Sorocaba, Sao Paulo, Brazil) were selected. Preparation of temporary crowns (Figure 2): two false teeth received morphological adaptation using acrylic resin, in order to resemble the anatomy of the lost elements and adapt to the remaining gum line conformation.
Edentulous region after mini-implants insertion ((a) and (b)); temporary crowns adapted to the heads of the mini-implants (c).

Installation of mini-implants (Figure 3): the insertion of the implants was transmucosal in occlusal-gingival position. Final retention of provisional crowns to mini-implants (Figure 3): The final coupling was completed with the partial filling of the cavity (approximately 1 mm below the alveolar ridge) with acrylic resin, still in plastic phase, to allow mechanical interlock between the crowns and heads of mini-implants after setting time.
