Summary
New dentures significantly improved chewing efficiency and reduced mastication time in patients with severe bone resorption after one year. Early assessments at five months did not show the full benefits of the new complete dentures.
Area of Science:
- Dentistry
- Prosthodontics
- Biomaterials
Background:
- Severe bone resorption impacts masticatory function in complete denture wearers.
- Long-term complete denture use (over 10 years) can exacerbate functional deficits.
Purpose of the Study:
- To evaluate masticatory efficiency and masticatory cycle duration in patients with severe bone resorption wearing new complete dentures.
- To compare outcomes at 5 months and 1 year post-denture delivery.
Main Methods:
- 14 asymptomatic patients with severe bone resorption participated.
- Masticatory efficiency and cycle duration were assessed using artificial food and a sieve system.
- Evaluations were conducted before, at 5 months, and 1 year after receiving new dentures.
Main Results:
- Masticatory efficiency showed significant improvement at 5 months, particularly with the 0.42-mm mesh.
- By 1 year, both masticatory efficiency and duration of the masticatory cycle demonstrated significant improvements.
Conclusions:
- Five months is insufficient to observe the full adaptation and functional recovery with new dentures.
- One year of new complete denture use leads to substantial improvements in masticatory efficiency and reduced mastication time.
