Abstract

Aim: The aim of this study was to evaluate immediately loaded implants, both clinically and radiographically, in extraction sites (IPIL) and healed sites (HSIL), rehabilitated using All-on-4/All-on-6 protocol, over a time span of 2 years.

Setting and design: The study proceeded under following phases of patient selection, placement of implants followed by immediate loading and then statistically analyzing the collected data.

Materials and methods: A total of 15 patients were evaluated, in 2 years, for study purpose. Among 87 immediately loaded implants, 44 were IPIL and 43 were HSIL. The bone level was measured using Implant abutment junction as reference point, at 0, 6, 12, 18 and 24 months. Bone loss was calculated as difference of mean.

Statistically analysis: The collected data was statistically analyzed using independent t-test (P < 0.05).

Results: The average bone loss for 2 years was 1.39 mm and 1.17 mm, in IPIL and HSIL group respectively with 100% implant survival rate and no statistical difference (P < 0.05).

Conclusion: Full arch prostheses can be successfully delivered by immediate loading of implants regardless of placement (healed or extraction sites).

Keywords: All-on-Four; All-on-six; HSIL; full mouth rehabilitation; immediate loading; immediate placement immediate loading.
