AIMS AND OBJECTIVES: Aim of this study was to assess the use and efficacy of lateral bone expansion screws. Also to evaluate the retention of labial plate thickness after implant placement with bone expansion technique by CBCT. MATERIALS AND METHODS: A total of 13 patients with inadequate alveolar width (2.5mm to 5mm) and with adequate bone height were included in the study. A total of 17 implants were placed immediately after ridge expansion. Gradual expansion of alveolar ridge was carried out in stepwise manner with increasing diameter of expansion screws. Minimal or no peri-implant warming had occured during expansion which was again favourable for immediate implant placement.
