Summary
A novel two-piece record base/occlusion rim system simplifies dental procedures. This innovative design enhances efficiency by allowing easy adjustment and replacement of the occlusion rim without unscrewing the base, saving valuable clinical time.
Area of Science:
- Dental Prosthodontics
- Biomaterials Engineering
- Clinical Dentistry
Background:
- Screw-retained record bases are crucial for stable maxillomandibular relationship recording in implant-supported prostheses.
- Current methods involving repeated intraoral removal and reattachment of occlusion rims are time-consuming and inefficient.
Purpose of the Study:
- To introduce and evaluate a two-piece record base/occlusion rim system designed for improved efficiency in prosthodontic procedures.
- To eliminate the need for repeated screw manipulation during intraoral adjustments.
Main Methods:
- Development of a two-piece record base and occlusion rim system.
- The record base remains intraorally screw-retained.
- The occlusion rim is designed for friction-fit retention over the record base.
Main Results:
- The two-piece system allows the record base to remain intraorally throughout the appointment.
- Occlusion rim adjustments, removal, and replacement are facilitated without screw manipulation.
- This method offers improved convenience and efficiency compared to traditional single-piece systems.
Conclusions:
- The two-piece record base/occlusion rim system offers a more efficient and convenient workflow for recording maxillomandibular relationships.
- This innovation streamlines the process of intraoral adjustments for implant-supported fixed prostheses.
