[Kinetics of supporting teeth in patients with partial dentures]

|July 1, 1978
Summary
This pilot study on partial lower jaw prostheses found that embedded prostheses improve tooth movement kinetics, making them more physiological. However, the direction of movement in embedded prostheses doesn't match the norm, suggesting a splinting effect.
Area of Science:
- Dental prosthetics
- Biomechanics
- Kinetics
Context:
- Partial lower jaw prostheses can affect the biomechanics of supporting teeth.
- Understanding tooth kinetics is crucial for prosthesis design and patient outcomes.
Purpose:
- To investigate the kinetics of supporting teeth in patients with partial lower jaw prostheses.
- To compare tooth movement during mastication with and without embedded partial prostheses.
Summary:
- The study monitored two female patients over 10 weeks using inductive distance measures.
- Initial findings revealed unphysiological movement in end-support teeth. Canine guidance showed normal kinetics.
- Embedded partial prostheses altered the direction of tooth kinetics, with values approaching physiological norms, acting as a splint for abutment teeth.
Impact:
- Embedded partial prostheses may enhance the functional kinetics of supporting teeth.
- The splinting effect of prostheses needs further investigation regarding long-term physiological norms.
- This research provides insights into the biomechanical behavior of teeth supporting partial dentures.
