A partial denture replaces some missing teeth while clasping onto the remaining natural teeth, and it can be made for one arch while a full denture replaces the other. This educational case note describes a partial lower denture fitted alongside a replacement full upper denture at Greenvale Dental House. It is general information only; results vary and a clinical consultation is needed to assess suitability.
Presenting Clinical Problem
A patient presented to Greenvale Dental House with a loose, ageing upper denture and gaps from missing lower teeth.
- An existing upper denture that had become loose with poor retention
- Visible discolouration on the denture base despite regular cleaning
- Speech difficulties linked to denture movement
- Concerns about the denture’s appearance
- Missing lower teeth alongside the remaining natural lower dentition
The primary objective was to replace the existing upper denture with a full upper denture and to restore the missing lower teeth with a partial lower denture.
Treatment Approach
Planning followed a comprehensive examination of the dentures, tissues and remaining lower teeth.
Assessment and planning
- Comprehensive oral examination and denture assessment
- Evaluation of the existing denture’s fit, retention and appearance
- Assessment of the oral tissues, ridge anatomy and remaining lower teeth
- Discussion of denture options and material selection
- Planning a full upper denture and a partial lower denture
Impressions and fabrication
- Primary and secondary impressions for accurate tissue recording
- Jaw relationship records and vertical dimension establishment
- Tooth selection for shade, size and shape
- A try-in appointment to check appearance and function
- Laboratory fabrication of the final dentures
Delivery and adjustment
- Delivery and insertion of the final dentures with fit checks
- Occlusal adjustment and assessment of function
- Aftercare instructions and adjustment protocols
- A schedule for follow-up and denture maintenance
Clinical Outcome
A full upper denture and a partial lower denture were fabricated and delivered. At review, retention and function were assessed as improved compared with the previous prosthesis, and the patient was maintaining appropriate denture hygiene.
Individual results vary. Retention depends on ridge anatomy, saliva and muscle control, and all dentures involve an adaptation period, which is prolonged for some patients. A partial denture also relies on the health of the remaining natural teeth that support it. Looseness can recur as ridge resorption continues, requiring relining or replacement. Outcomes cannot be guaranteed, and suitability is determined at a clinical consultation.
Frequently Asked Questions
What is the difference between a partial and a full denture?
A partial denture replaces some missing teeth and clasps onto the remaining natural teeth, so it depends on those teeth staying healthy. A full denture replaces all the teeth in an arch and rests on the gum ridge. A patient can have a full denture in one arch and a partial denture in the other, as in this case.
What are the alternatives to a partial denture?
Depending on the number and position of missing teeth, options such as a single dental implant or a fixed bridge may be considered. Each has different requirements for bone, adjacent teeth and maintenance, and the right choice is determined at a clinical assessment.
Can new dentures look more natural than older ones?
Modern fabrication allows improved aesthetics compared with older designs, and teeth can be selected for shade, size and shape to suit the face. Appearance still depends on ridge position, lip support and facial anatomy. Realistic expectations matter, as a denture replaces missing teeth and cannot copy natural dentition exactly.
