简要总结
Assessing whether is there a difference between computer-guided ridge splitting and conventional technique with simultaneous implant placement in patients with maxillary width deficiency.
详细描述
Two groups one treated with ridge splitting using guided surgery and the other one treated with freehand surgery and both groups had simultaneous dental implants the first one had guided placement and the other one was freehand.

研究组 & 干预措施
study group treated with guided ridge splitting.
virtual surgical planning using planning software Blue Sky Bio (BSB) and 3D printed surgical guide are fabricated to guide the ridge splitting procedure and implant drilling and placement.
干预措施: dental implant placement with ridge splitting. (Procedure)
control group treated with conventional ridge splitting.
Freehand surgery is done including ridge splitting and implant plaement
干预措施: dental implant placement with ridge splitting. (Procedure)
