Summary
Adding impression material to dentures significantly widens the occlusal table, influencing denture space. This study demonstrates how material volume affects denture positioning relative to the alveolar ridge.
Area of Science:
- Dental Materials Science
- Prosthodontics
- Biomechanics
Background:
- Accurate denture space is crucial for function and patient comfort.
- Understanding the influence of impression materials on denture space is essential for improved prosthodontic outcomes.
Purpose of the Study:
- To investigate how adding impression material affects denture space using piezographical records.
- To determine the impact of incremental impression material additions on the dimensions of the occlusal table.
Main Methods:
- Ten edentulous patients received trial dentures with impression material.
- Patients performed phonetics to conform oral tissues to the denture space.
- Occlusal analogues were created and measured to assess changes in bucco-lingual width and position.
Main Results:
- Bucco-lingual widths of the occlusal table significantly increased with material addition (P1-P4).
- Denture space positioning remained consistent buccally (1.5-1.9 mm) relative to the alveolar crest, irrespective of material volume.
Conclusions:
- Denture space is effectively regulated by the volume of impression material used.
- Optimal denture placement is slightly buccal to the residual alveolar ridge crest.
