Fig 1

Wilckodontics: mucoperiosteal flap are reflected (yellow incision line), vertical and horizontal corticotomy cuts (black lines), placed along with alveolar perforations (black dots) on the buccal and palatal side, followed by bone augmentation (white dots)

Fig 2

Single flap monocortical piezosurgery: mucoperiosteal flap are reflected (yellow incision line), interradicular alveolar corticotomy grooves with Piezoelectic Knife (black lines); “Y”-shaped cuts in interdental crest area to preserve crestal bone

Fig 3

Single flap monocortical perforations: a series of circular holes (black dots) are made on areas of intended tooth movement;yellow line, incision for flap

Fig 4

Piezocision: after the buccal interproximal gingival incision (yellow lines), the Piezotome is inserted to a depth of approximately 3 mm to do the decortications (black lines) that will start the RAP; limited bone augmentation (white dots) is possible through subperiosteal tunneling

Fig 5

Piezopuncture is performed on the areas ofintended tooth movement with a piezosurgical instrument, penetrating overlying gingiva into the cortical bone (black dots)
