Summary
Brånemark implant-supported overdentures show high success in the mandible but less favorable outcomes in the maxilla. Maxillary overdentures experienced higher failure rates and more mucosal issues compared to mandibular placements.
Area of Science:
- Dental Implantology
- Prosthodontics
- Oral Surgery
Background:
- Overdentures supported by Brånemark implants are a common restorative option.
- Previous studies have reported varying success rates for implant-supported prostheses.
Purpose of the Study:
- To evaluate the success rate and complications of Brånemark implant-supported overdentures in the maxilla and mandible.
- To compare the outcomes of overdentures with fixed implant-supported restorations.
Main Methods:
- A prospective study involving nine clinical centers.
- 133 patients received overdentures supported by 117 maxillary and 393 mandibular Brånemark implants.
- Follow-up included annual checkups after denture placement.
Main Results:
- Mandibular overdentures demonstrated success rates comparable to fixed prostheses.
- Maxillary overdentures showed less favorable results than fixed restorations.
- Higher implant failure rates (32 removed, 29 lost to follow-up) and unfavorable mucosal reactions were observed in the maxilla.
Conclusions:
- Brånemark implant-supported overdentures are effective in the mandible.
- Maxillary overdenture outcomes may be influenced by patient selection and bone quality.
- Further investigation into maxillary overdenture treatment protocols is warranted.
