Summary
The Dahl concept creates interocclusal space for resin-bonded fixed partial denture retainers. This technique successfully retained a replacement for a missing mandibular molar for nine years.
Area of Science:
- Dental Prosthodontics
- Restorative Dentistry
Background:
- Creating adequate interocclusal space is crucial for fabricating resin-bonded fixed partial denture (FBPFD) retainers.
- The Dahl concept offers a method for managing occlusal space challenges in restorative dentistry.
Purpose of the Study:
- To present a technique for establishing interocclusal space using the Dahl concept for FBPFD retainers.
- To evaluate the long-term clinical success of a FBPFD fabricated using this technique.
Main Methods:
- Application of the Dahl concept to create interocclusal space.
- Fabrication of a cantilevered resin-bonded fixed partial denture to replace a missing mandibular first molar.
Main Results:
- The described technique successfully created the necessary interocclusal space.
- The cantilevered FBPFD was successfully retained for a 9-year clinical review period, demonstrating long-term stability.
Conclusions:
- The Dahl concept is an effective method for achieving interocclusal space in FBPFD preparations.
- Resin-bonded fixed partial dentures utilizing this technique can provide durable and successful long-term restorations.
