    Aim: To assess the treatment outcome and survival rate of short implants used for single and multiple teeth replacement after one year of placement. Methodology: This study included 26 patients aged 21 to 70 years (mean 47.7 years) that received 55 short dental implants (Bicon system. Boston USA) for single and multiple teeth replacement in a teaching hospital and private dental clinic in Lagos, Nigeria between 2012 and 2016. Demographic data such as age, sex, location of implant, length of implant used, placement technique and type of restoration used (crown or bridge) were extracted from the patient’s record. Patients were recalled one year after implant placement and assessed clinically for implant mobility, pain, suppuration, gingival recession and inflammation around the implant retained restorations. Marginal bone loss and peri-implant radioluscency were evaluated using periapical radiograph. Results Survival rate of short implants placed in this study was 96.4%. None of the surviving implants showed a marginal bone loss greater than 1.5mm one year after placement. None of the surviving and functional implant restoration demonstrated mobility, suppuration or peri-implant radiolucency during the review period. The 8mm implants demonstrated a statistically significantly higher survival rate compared with the 6mm implants (p=0.039).The 6mm implants that failed were placed immediately after extraction (immediate placement). A significantly higher percentage of failure was recorded among the implants placed in the lower premolar region(p=0.001). Conclusion. This study demonstrated that the use of short implants is a viable option in dental implant treatment.
