A rationale for retrievability of fixed, implant-supported prostheses: a complication-based analysis

Area of Science:

• Dental Implantology
• Prosthodontics
• Biomaterials

Background:

• Fixed implant-supported prostheses are common in restorative dentistry.
• Biologic and technical complications are frequently observed with these restorations.
• The oral environment presents unique challenges to the longevity of implant prostheses.

Purpose of the Study:

• To provide a rationale for the retrievability of fixed, implant-supported prostheses.
• To analyze the incidence and types of complications associated with implant prostheses.
• To discuss the etiologies of these complications and their impact on prosthesis longevity.

Main Methods:

• Conducted electronic searches of MEDLINE (Ovid) database up to May 2006.
• Performed manual searches of identified articles and 11 peer-reviewed dental journals.
• Established a hierarchy of evidence to support a complication-based analysis.

Main Results:

• Biologic and technical complications are prevalent in fixed implant-supported dentistry, affecting function and esthetics.
• Complications occur despite good design and clinical expertise, challenging permanent cementation.
• Clinicians must weigh retrievability costs against benefits, highlighting a need for more evidence.

Conclusions:

• Permanent cementation of implant prostheses may be incompatible with the high likelihood of failure.
• Retrievability of fixed implant-supported prostheses is essential for optimal patient-centered care.
• Further evidence-based information is needed to guide decisions on prosthetic retrievability.
