Surgical procedure. (a) Corticotomy: the circumscribing corticotomy was performed with a round bur ( 1.5 mm) under sterile saline irrigation. (b) MBCP⁺ (Biomatlante, Vigneux de Bretagne, France), composed of 20% hydroxyl apatite and 80% β-tri-calcium phosphate, was used as the alloplastic bone graft material. The graft bone was applied soaked in blood; 1 g of the MBCP⁺ was grafted on the surgical surface. (c) A closed coil spring made of nickel-titanium shaped memory wire of 200 g force was applied to the second and third premolars in a buccolingual direction in the maxilla and (d) in the mandible.
