Abstract

Objectives: To investigate the survival rate of short (≤9 mm) implants restored with single-unit, nonsplinted crowns after an average follow-up of 37 months (21–94 months). Materials and Methods: Two hundred and twenty-one implants placed in 168 patients (74 men, 94 women, aged 34–87 years, mean = 61 years). Implant lengths were 6 (n = 16), 8 (n = 166), 8.5 (n = 2), or 9 mm (n = 34). The implant diameters ranged from 3.7 to 5.6 mm. Implants were placed in the maxillary (n = 44) and mandibular arches (n = 176). Results: Survival rate was 94.1% (maxilla [88.6%] and mandible [96.0%]) and 12 early failures (first 4 months) and 1 late failure (4.5 years in the maxillary molar region) observed. Of the 12 early failures, 4 were in the maxilla (2 premolars and 2 molars) and 8 in the mandible (2 premolars and 6 molars). The early failures were 11 implants of 8 mm long and a 9-mm implant. Smoking cigarettes, diabetes mellitus, and bone augmentation procedures were not associated with implant failure significantly (P > 0.05). Conclusions: Survival rate of short implants restored with single-unit, nonsplinted restorations over an average period of 37 months was favorable and comparable with longer implants.
