Summary
The IMZ TwinPlus screw implant demonstrates a 91% survival rate over 4.5 years, comparable to other dental implant systems. This titanium screw implant offers a wider range of applications compared to the traditional IMZ cylinder implant.
Area of Science:
- Dental Implantology
- Biomaterials Science
- Surgical Innovation
Context:
- The IMZ-system has been in clinical use for over two decades, with the IMZ-TwinPlus modification introduced in 1995.
- This study focuses on the IMZ-TwinPlus, a self-threading cylindrical titanium screw with a structured surface.
Purpose:
- To prospectively analyze the clinical success of the IMZ-TwinPlus implant system.
- To evaluate peri-implant soft tissue conditions, bone loss, and implant failure rates.
- To assess the long-term performance of this dental implant over a maximum of 4.5 years.
Summary:
- A prospective trial examined 278 IMZ TwinPlus implants in 68 patients (1995-2000).
- After a mean follow-up of 30 months (max 54 months), 155 implants in 38 patients were re-examined.
- The implant failure rate was 6%, with an in situ rate of 91% and a Kaplan-Meier survival rate of 91% at 54 months.
Impact:
- The IMZ TwinPlus implant system shows survival rates comparable to established dental implant systems.
- This screw implant design expands indications compared to the classical IMZ cylinder implant.
- Provides crucial data on the long-term efficacy of a modified dental implant system.
