Long-term results of immediately loaded interforaminal implants

Area of Science:

• Dental Implantology
• Prosthodontics
• Oral Surgery

Background:

• Dental implants provide a stable foundation for prosthetic restorations.
• Immediate loading protocols aim to reduce treatment time.
• Bar-retained overdentures offer enhanced stability and function.

Purpose of the Study:

• To evaluate the long-term clinical outcomes of immediately loaded Straumann implants.
• To assess the success rates of implants supporting bar-retained overdentures.
• To determine if a 4-month healing period is mandatory for these specific implants.

Main Methods:

• Retrospective collection of long-term data from patients treated between 1981 and 1991.
• Immediate loading of Straumann implants with a bar and hybrid prosthesis on the day of surgery.
• Clinical re-examination and statistical assessment of available patients and implants.

Main Results:

• Follow-up was possible for 23 out of 44 patients (89 implants).
• Mean observation period was 12.2 years (range 8-18 years).
• Implant success probability was 83.3% (3 lost, 5 failed to meet criteria).

Conclusions:

• Immediately loaded interforaminal Straumann implants with bars demonstrate favorable long-term results.
• The conventional 4-month healing period may not be required for this treatment modality.
• This suggests potential for accelerated treatment timelines in select cases.
