Aim&Background: The aim of the present case series was to evaluate the 1-year clinical results of 4 mm long bone level implants used to rehabilitate single premolar gap in mandible. Materials & Methods: Six systemically healthy, non-smoker patients (3 male, 3 female, age range 48-62) with a single missing premolar tooth in the mandible were included in the study. A two stage surgical protocol was followed and the patients received a total of 6 implants, 4.0mm in length and ø5.0 or 5.5mm (i-system, Novodent SA, Switzerland). The implants were uncovered at 3rd month and a single unit porcelain fused to metal restoration was fabricated thereafter. Radiographic evaluations were performed at baseline and 6-, 12-months after loading. Measurements were done by a digital image analysis system Results: The implants osseointegrated uneventfully with no sign of postoperative complications. All the implants remained in function during the evaluation period. Crestal bone loss was 0.10 ± 0.19mm and 0.19±0.36mm at 6 and 12 months respectively. Conclusion: Within the limits of the present short term clinical case series, it may be suggested that 4mm short implants may be regarded as a promising treatment option in the rehabilitation of single premolar gaps in the mandible
