Managing the Unstable Mandibular Complete Denture – Tooth Placement and the Polished Surface

Area of Science:

• Dentistry
• Prosthodontics
• Dental Materials

Background:

• Conventional mandibular complete dentures present unique challenges compared to maxillary dentures.
• An atrophic mandible exacerbates difficulties due to poor-quality supporting structures.
• Implant-retained prostheses are beneficial but not universally feasible, necessitating improved conventional techniques.

Purpose of the Study:

• To discuss factors influencing the success of conventional lower dentures.
• To highlight the role of tooth placement, polished surfaces, and the neutral zone.
• To provide clinical relevance for improving denture outcomes.

Main Methods:

• Review of factors influencing conventional mandibular denture success.
• Discussion of impression quality and registration importance (previously reviewed).
• Explanation of techniques for assessing and recording the neutral zone.

Main Results:

• Polished surface contouring significantly impacts lower denture outcomes.
• Tooth prescription is crucial for successful mandibular denture construction.
• Understanding and utilizing the neutral zone improves denture stability and function.

Conclusions:

• Optimizing tooth placement, polished surface design, and neutral zone recording are key to successful conventional lower dentures.
• These factors are critical when implant-retained options are not viable.
• Clinical attention to these details can enhance patient satisfaction and denture performance.
