Abstract

When there was horizontal bone loss, we can consider ridge splitting instead of guided bone regeneration (GBR).
It had several advantages, for example, simultaneous installation, little post-surgical trauma. The purpose of this
study was to discuss clinical usefulness of ridge splitting procedure by evaluation of course of 35 implants installed
to 17 patients by ridge splitting in department of periodontology, Veterans Health Service Medical Center from March,
2011 to February, 2013. The mean age of patients is 66.1, from 58 to 71, and the number of men and women was
each 13 and 4. Alveolar crestal splitting was operated with piezo electric device, tapered expansion chisel and kit
under local anesthesia, and implants were installed simultaneously in all cases. One operator applied xeno and/or
allogenic grafting materials to peripheral gap, and covered with collagen membrane. Panoramic radiographs were
taken during the prosthetic loading (baseline period) and the 1 year control visit. The digital cailper was used to
measure the distance from the implant-abutment junction to the peri-implant marginal bone level, which was divided
into a mesial and a distal side. We compared the bone loss level between the baseline and the 1 year control visit
through radiographs. In results, the survival rate was 97.14%. One implant were extracted due to failure of
osseointegration at second surgery. The mean values of the marginal bone loss in radiographs between the baseline
and the 1 year control visit were 0.17 ± 0.07 mm on the mesial side and 0.19 ± 0.18 mm on the distal side.
Although this case series had a short term period and small number of cases. However, our authors concluded that
alveolar ridge splitting procedure can be effective for recovering the insufficient horizontal defect.
