Hypothesis
Multiple abutment replacements are associated with a higher prevalence of peri-implant diseases.
Conclusion
The one-abutment one-time concept was associated with a lower prevalence of peri-implant diseases.
Supporting Evidence
- Patients with the one-abutment one-time concept had a 94.4% health rate compared to 0% in the control group.
- Abutment replacement was a significant predictor of peri-implant diseases.
- The mean bone loss was significantly greater in the abutment replacement group.
Takeaway
Changing the part that connects the implant to the crown too many times can lead to more gum problems around the implant. Keeping the same part helps keep the gums healthy.
Methodology
This retrospective study analyzed 27 edentulous patients with 108 implants, comparing one-abutment one-time care with conventional multiple abutment replacements.
Potential Biases
Potential biases due to the retrospective nature and the absence of randomization.
Limitations
The study is retrospective, lacks a sample size calculation, and has varying follow-up periods.
Participant Demographics
16 females and 11 males, mean age 74.2 years.
