[Clinical study on the contact between the partial denture and the alveolar process]
Deutsche Zahnarztliche Zeitschrift
|October 1, 1975
Summary
Most dental bridges rest on the gingiva, not just the bone, potentially causing issues. This study examined bridge resting positions to assess pressure-less contact with the alveolar ridge.
Area of Science:
- Dentistry
- Prosthodontics
- Biomaterials
Context:
- Clinical evaluation of dental prosthetics.
- Assessment of bridge fit and adaptation.
- Pre-cementation examination of fixed bridges.
Purpose:
- To evaluate the resting position of clinically prepared dental bridges on the alveolar ridge.
- To determine if bridges meet ideal pressure-less resting requirements.
- To quantify the extent of mucosal contact by the bridge base.
Summary:
- 53 dental bridges were analyzed for their resting contact with the alveolar ridge before cementation.
- The study found that all bridges exhibited some degree of base contact with the mucosa, not exclusively pressure-less resting.
- In 42 of 66 examined cases, the bridge base had 50-100% contact with the mucosa, indicating significant soft tissue engagement.
Impact:
- Highlights potential issues with dental bridge adaptation and fit.
- Suggests a need for improved pre-cementation assessment techniques.
- Informs prosthodontic practices regarding optimal bridge-to-tissue contact for longevity and patient comfort.
