ACs are congenital heterogenous soft tissue and bone defects that attain different volumes and shapes. Closure and grafting are usually addressed before canine eruption date. This will enhance health of teeth in and adjacent to the AC, confer support to the nose and lip, assures a donor site is of acceptable volume and guarantees minimal to no later maxillary growth and facial alteration.The first bone grafting attempts in cleft patients were described by Lexer 1908 and Drachter 1914. They reported the use of the small finger as a pedicled bone transplant. [1] Since then, different techniques and donor sites have evolved and revised. Particulate cancellous spongy bone from the anterior iliac crest is the most used graft as it is autogenous, osteogenic and can provide generous amounts. [2,3] Unfortunately, in unilateral cases, the attainment of symmetry in the anterior nasal aperture and alveolar bone graft to the non-clefted side is not consistently realized. [4] Also, a resorption potential of up to 64% was reported. [5] Significant advancements in computer-assisted surgery over the past several years have resulted in straightforward surgical procedures. It also guarantees a shorter surgical procedure and a lower risk of complications, all of which promote patient acceptance and satisfaction.6 In alveolar cleft defect, computer guided steps can generate a patient specific implant that provide a near normal vertical and horizontal ridge dimensions. [7] Dual surgical guidance is a novel protocol that employs two surgical guides designed to generate a patient specific graft. The first guide will have cutting slots that define the graft side walls contour and angles while the second one will outline the superior and inferior walls. This study was designed to investigate the clinical and radiological outcomes plus incidence of complications following dual surgical guidance in reconstruction of unilateral ACs.
