ANSWERS

What is the difference between a partial and a full denture?

A partial denture replaces some missing teeth and clasps onto remaining natural teeth for retention. A full denture replaces an entire arch when no natural teeth remain and seats on the gum tissue, with the upper arch using palatal suction for retention. Partials preserve existing dentition;

More on this topic

When should I prescribe a partial denture versus a full denture for my patient?

Prescribe a partial when the patient retains sound, periodontally stable abutment teeth that can support clasps or precision attachments. A full denture is indicated when the arch is edentulous or when remaining teeth are non-restorable and slated for extraction. Consider bone volume, opposing dentition, and long-term treatment planning. If borderline teeth exist, discuss immediate dentures or transitional partials with the lab before finalizing the design.

What impressions and records does the lab need for a partial versus a full denture?

For a partial, submit a final impression capturing all remaining teeth, edentulous ridges, and vestibular extensions, plus a design prescription indicating rest seats, guide planes, and clasp placement. For a full denture, provide a border-molded final impression of the entire arch, a bite registration at the established vertical dimension, and shade and mold selection. Digital scans are accepted when soft tissue detail and peripheral extensions are adequately captured.

What framework and base materials are available for partial and full dentures?

Partial denture frameworks are commonly fabricated in cast cobalt chromium for rigidity, or in flexible thermoplastic resin for esthetic clasp areas. Full dentures use heat-cured acrylic bases with acrylic or porcelain denture teeth. Metal-reinforced bases and milled options are available for patients with heavy occlusal load or a history of fracture. Discuss the case with the lab if the patient has known monomer sensitivity or specific esthetic demands.

How does treatment planning differ when transitioning a partial denture patient to a full denture?

When remaining abutments are failing, plan the transition in stages. An immediate full denture can be delivered on the day of final extractions using the existing partial as a reference for tooth position, midline, and vertical dimension. Provide the lab with preoperative records, a diagnostic impression, and a surgical plan indicating which teeth will be removed. A reline or new prosthesis is typically needed after ridge healing.

What turnaround should I expect from the lab for partial and full denture cases?

Turnaround depends on the number of try-in appointments prescribed. A standard full denture involves a custom tray, bite rim, wax try-in, and finish, with lab time between each stage. Cast partials require framework try-in before tooth setup. Digital workflows can reduce appointments when clinically appropriate. Contact the lab directly to confirm current scheduling for your specific case type and any rush accommodations.
