Summary
Long-term survival of 2-implant mandibular overdentures depends on consistent prosthodontic maintenance. This case report highlights the successful rehabilitation of edentulous adults with implant-supported overdentures after 22 years.
Area of Science:
- Dental Implantology
- Prosthodontics
- Biomaterials
Background:
- Mandibular implant overdentures offer a successful treatment for edentulous adults, enhancing quality of life.
- Long-term implant survival necessitates diligent prosthodontic maintenance.
Observation:
- Two elderly edentulous patients with 2 hydroxyapatite (HA)-coated implants supporting mandibular overdentures were evaluated after 22 years.
- Implants demonstrated osseointegration and survival, but overdentures experienced recurrent retention and stability issues.
Findings:
- Prosthodontic rehabilitation involved replacing worn attachment systems and fabricating new overdentures.
- A conservative approach was adopted, focusing on appropriate attachment system selection.
Implications:
- Continued prosthodontic maintenance is crucial for the longevity of 2-implant supported mandibular overdentures.
- This case underscores the importance of timely interventions and material selection in maintaining implant-supported prostheses over decades.
