Rehabilitation with dental implants is, without doubt, an ordained technique. The clinical utilization of dental implants has accelerated in recent years, and new applications continue to emerge. This retrospective study aims to report the implant dimensions commonly used for the posterior mandibular region. It was done at Saveetha Dental College and Hospitals. A total of 391 patients with 670 implant sites within the 20-80 age group who had undergone implant placement were included in the study. The case sheets of patients were obtained from patient information archives. The data on each patient were obtained and tabulated. Out of the 391 patients, 52.2% were males and 47.8%% were females; 33.3% belonged to the < 35 age group, 34.5% belonged to the 35-46 age group, and 32.2% belonged to the > 46 age group. The prevalence rate of replacement for mandibular molars was 85.2%; for mandibular premolars, 14.8%. Implant dimensions for posterior mandibles were found to differ based on gender and age group. Males had a greater mean implant width compared to females. Implant dimensions with increased height were used in premolars compared to molars. Implant dimensions with increased width were used in molars compared to premolars. In general, implant width ranged from 3.3 to 5 mm and implant height ranged from 9.5 to 13 mm in the mandibular molar region.
