How Long Does It Take to Make Dentures After Impressions?

Dentures are removable appliances designed to replace missing teeth and surrounding tissue. Their creation requires meticulous precision and multiple steps, involving close collaboration between the dental clinic and a specialized laboratory to ensure the final prosthetic fits accurately. The timeline from the final impression to receiving the finished appliance is a multi-phased journey that varies based on the individual case’s complexity. Understanding the average expected time and the steps involved helps manage expectations for this custom medical device.

The Standard Timeline for Denture Fabrication

The typical duration for fabricating a conventional complete denture, measured from the final impression appointment to the initial delivery, generally falls within a range of three to six weeks. This timeline accounts for the necessary back-and-forth between the dental office and the laboratory, including multiple patient appointments for verification steps. The average four-week period reflects the standard clinical and technical procedures required to craft a prosthesis that is both functional and aesthetically pleasing. The process is sequential, meaning a delay or necessary revision at any point will extend this overall timeline before the final appliance is ready for insertion.

Key Stages in the Manufacturing Process

The final impression serves as the mold used by the laboratory to create a master cast, a stone model that precisely replicates the patient’s oral anatomy. Technicians fabricate a custom record base and wax rims on this cast to determine the correct vertical dimension and position of the new teeth. These wax rims are temporarily seated in the patient’s mouth to record the correct jaw relationship, lip support, and midline, which are crucial measurements for a proper fit.

The next significant stage is the wax try-in, where the selected artificial teeth are temporarily set in wax on the base for approval by the clinician and patient. This appointment verifies aesthetics, such as tooth shade and arrangement, and function, including bite alignment and speech phonetics. If the fit, appearance, or occlusion is not correct, the wax setup is sent back to the lab for modification, which must be approved before the case can proceed.

Once the wax try-in is approved, the final laboratory processing begins, which typically takes one to two weeks. During this phase, the wax supporting the teeth is replaced with a durable acrylic resin through a process involving flasking, packing, and curing the material under heat and pressure. This curing process solidifies the pink acrylic base, which mimics the gum tissue, and locks the artificial teeth permanently into place, creating the final appliance ready for delivery.

Variables That Affect the Completion Time

The primary factor influencing the overall timeline is the type of denture being fabricated. Conventional dentures, which involve multiple clinical appointments and laboratory steps for precise measurements, take the longest time. Immediate dentures follow a faster initial timeline because they are placed immediately after tooth extraction. The laboratory work is done based on pre-extraction records, bypassing the traditional jaw relation and wax try-in stages. However, immediate dentures require more frequent and time-consuming adjustments later on as the tissues heal.

The complexity of the individual case also plays a role in fabrication duration. Cases involving severe discrepancies in the ridge shape or specialized requests for aesthetics may require additional lab time and more try-in appointments. The most common source of delay is the need for revisions if the wax try-in does not meet the patient’s or clinician’s standards, which resets the clock for a portion of the lab work. Scheduling efficiency, including the time lag between necessary appointments, can significantly extend the period until final delivery.

The Delivery and Post-Insertion Adjustment Phase

The process does not conclude with the initial delivery of the finished appliance, as the patient’s mouth must adapt to the new prosthetic. The insertion appointment involves the clinician making final, minor adjustments to the fit and bite. Within 24 to 72 hours of wearing the new appliance, a follow-up appointment is typically scheduled to address any initial sore spots or pressure points.

Adapting to the denture involves a series of adjustment appointments, often occurring over the first few weeks. As the soft tissues settle and respond to the pressure of the new appliance, minor modifications to the acrylic base may be necessary to ensure maximum comfort and stability. These adjustments are fundamental for achieving a long-term, comfortable fit and function.
