Implant complications and failures: the complete overdenture.

Area of Science:

• Dentistry
• Prosthodontics
• Dental Implantology

Background:

• Implant-retained overdentures are an advanced prosthetic solution for edentulous patients.
• These restorations offer advantages over conventional dentures but exhibit variable success rates.
• Implants supporting overdentures in the maxilla demonstrate a notably higher failure rate compared to other sites.

Purpose of the Study:

• To identify and analyze common restorative complications associated with implant-retained overdentures.
• To investigate the maintenance challenges and costs linked to these dental implant restorations.
• To review various implant systems and report clinical experiences regarding overdenture complications.

Main Methods:

• Literature review of multiple implant systems used for overdentures.
• Analysis of clinical experiences from referred cases.
• Inclusion of authors' own clinical case data.

Main Results:

• Maxillary implant overdentures show a significantly higher failure rate.
• Restorations require substantial maintenance, leading to increased time and cost.
• Common complications and maintenance problems are prevalent.

Conclusions:

• Implant-retained overdentures, particularly in the maxilla, present unique challenges.
• Effective management of complications and maintenance is crucial for long-term success.
• Further research and improved techniques are needed to enhance the survival and reduce the burden of these restorations.
