Introduction: As known, both implant diameter and length affect stress in the posterior mandible with low bone quality. Furthermore, implant diameter was more effective in reducing cortical bone stress and in improving implant stability under both axial and buccolingual loads, while implant length was more effective in reducing cancellous bone stress. Aim: To evaluate the most commonly used implant width and height values in the mandibular posterior region. Materials and methods. A retrospective study was conducted using the records of patients from the University hospital. Data on implant dimensions (implant height and implant width) placed in mandibular posteriors was collected (sample size=321) and analysed in association with age and gender. Descriptive statistics and chi-square association were done.Results and discussion: In this study, out of the 321 implants placed (n=321), the most frequent implant diameter was of 4.1-4.5 mm (245, 76.32%), followed by 4.6-5 mm (53, 16.51%) and 3.3-4 mm (23, 7.17%). The 8-10 mm length (200, 62.31%) was the most frequently used implant size for implantation, followed by 112 (34.89%) cases with 11-12 mm and 9 (2.80%) cases with 13-14 mm.Conclusions: In spite of its limitations, the study was aimed at presenting the demographic characteristic of dental implants placed in the posterior area. According to the results obtained, the most commonly placed implant site was the mandibular right molar area. The 4.1-4.5 mm in diameter and 8-10 mm in length were the most used implant sizes.
