Aim: Aim of this study was to evaluate crestal bone level changes and patient satisfaction level of single versus two Titanium-Zirconium (Ti-Zr) implants used for mandibular overdentures.

Materials and methods: A randomized controlled trial with a follow-up period of 1-year has been planned and the interim results are presented with 34 Ti-Zr implants (12 single, 11 double) placed in 23 patients (average age 64-years). All implants were restored with immediate loading protocols using Locator® attachments to mandibular overdentures by single operator and observed at 1 month and 1 year. The crestal-bone-level changes were measured with digital periapical radiographs using inbuilt software. The patient-satisfaction level was evaluated using 100 mm visual analogue scale (VAS) with readings presented in percentage.

Results: Out of 34, 1-median implant was failed to osseointegrate within 20-days. Two-implant group (n=22) showed crestal bone-loss of 0.23 mm at 1-month and 0.67 mm at 1-year recall. Single-implant group (n=11) showed average crestal bone loss of 0.39 mm at 1-month and 0.88 mm at 1-year recall. Patient satisfaction level (mean VAS score) was increased from 38.3% to 49.7% after 1-month and to 54.5% after 1-year for single-implant-patients and from 40.5% to 54.8% after 1-month and to 58.9% after 1-year for two-implant-patients.

Conclusion: Average 0.16 mm (in 1-month) and 0.21 mm (in 1-year) more crestal bone loss was observed in single-implant-patients than two-implant-patients. Patients’ satisfaction level was improved by 11.4% in 1-month and by 16.2% in 1-year for single-implant-patients and by 14.3% in 1-month and by 18.4% in 1-year for two-implant-patients.
