Abstract
Horizontal lack of residual ridge width can complicate the implant procedures. Therefore, ridge construction prior to implant placement is a biomechanical requirement. Guided bone regeneration, bone grafting, alveolar ridge splitting and combinations of these techniques are used for the lateral augmentation of the alveolar ridge. The ridge splitting technique with simultaneous implant placement seems to be a minimally invasive treatment option for horizontal augmentation of narrow alveolar ridges with adequate vertical height. This paper thoroughly describes a segmental ridge splitting technique with both vertical and horizontal osteotomy cuts followed by the use of chisel and mallet to lateralise the buccal bone which was accompanied by GBR and simultaneous implant placement.
Highlights
Dental implants are one of the most predictable treatment options for the replacement of single missing tooth.[1,2,3,4] inadequate width of the alveolar ridge remains a major limitation in ideal implant placement
The ridge split technique requires a minimum of 3mm of bone width with at least 1mm of cancellous bone between the two cortical plates to ensure a good blood supply and allow instrumentation.The alveolar ridge splits by inducing a controlled green stick fracture between the cortical plates

The purpose of this paper is to describe a segmental ridge splitting technique with both vertical and horizontal osteotomy cuts followed by the use of chisel and mallet to lateralize the buccal bone. It was accompanied by GBR and simultaneous implant placement. A polyether impression (Pentamix, 3M ESPE, Minnesota, USA) was recorded and abutment trial was done in the subsequent appointment.
