Treatment may require a nystatin prescription. Once the cause of the sore spot is identified, the denture is adjusted and polished to eliminate the problem.

What are the steps for conventional denture fabrication?
9 steps for conventional denture fabrication: Make preliminary impression using a stock tray specifically designed for edentulous patients and alginate. Tray periphery may be enhanced with wax. Fabricate preliminary cast and custom impression tray. This cast should be slightly over-extended in the periphery.
What is hyperplastic tuberosity in dentures?
Hyperplastic Tuberosities When this patient assumes a protrusive position, the maxillary denture was tipped anteriorly leading to resorption of bone of the premaxilla and fibrous hyperplasia of the maxillary tuberosity 29.
Is conventional denture fabrication essential for transition to implant-retained prostheses?
Modern treatment options utilize dental implants, yet understanding the essential steps required for predictable conventional denture fabrication should aid clinicians seeking to transition patients to implant -retained prostheses.
How can clinicians increase the predictability of conventional complete dentures?
Successful patient outcomes with conventional complete dentures are possible. In order to achieve predictable success clinicians require technical skill, competent laboratory support and patient trust. The essential steps outlined here should help clinicians increase the predictability of their conventional removable prosthetic treatments.

How can you avoid Christensen phenomenon in complete dentures?
The space that occurred between the upper and lower posterior teeth is called Christensen phenomenon. In order to avoid this phenomenon the curves Spee and Wilson must be constructed.
What are the three restoring function of a complete denture?
Complete dentures consist of two main parts, namely the artificial teeth and the denture base. As described previously, an artificial tooth is used to restore the appearance of the natural tooth, its occlusion, oral function, and to assist in word pronunciation.
What are the post insertion complaints in complete denture?
There is always the possibility of problems arising after the delivery of the complete dentures. These problems can be examined in seven categories: pain, retention and stability loss, inadequate chewing, nausea, noises made by the dentures, poor esthetics, and problems relating to speech.
What is Christensen phenomenon?
[C. Christensen, Danish dentist and educator] A gap occurring in the natural dentition or between the opposing posterior flat occlusal rims when the mandible is protruded (posterior open bite). It can lead to instability in full dentures unless compensating curves are incorporated into the dentures.
What is incisal guidance?
Incisal guidance is the path on the lingual surface of the maxillary anterior teeth along which the mandibular anterior teeth glide, in neutro- or distoocclusion.
Why is curve of Spee important?
This normal occlusal curvature is required for an efficient masticatory system. Exaggerated curve of Spee is frequently observed in dental malocclusions with deep overbites. [1] Such excessive curve of Spee alters the muscle imbalance, ultimately leading to improper functional occlusion.
What is the plane of occlusion?
The plane of occlusion refers to an imaginary surface that theoretically touches incisal edges of the incisors and the tips of the occluding surfaces of the posterior teeth". A plane usually signifies a flat surface; however, it is not so where the occlusal plane is concerned.
What happens if the plane of occlusion is too low?
There is also tendency for accumulation of food in the buccal and lingual sulci [5]. An occlusal plane that is too low could lead to tongue and cheek biting [4].
What are the post insertion problems commonly encountered in RPD?
1. Pain and discomfort related to soft tissues or remaining teeth. 2. Difficulty seating or removing the RPD.
What are the problems with dentures?
That's why painful, ill-fitting dentures are the biggest problem facing denture wearers. Discomfort is usually due to dentures sliding inside the mouth because they don't fit snugly against the gums. Soreness and swelling soon result. Friction may cause painful calluses and sores to develop.
What is denture stomatitis caused by?
Denture stomatitis (or oral stomatitis) is usually caused by candida — a type of fungus (yeast). It's normal to have small amounts of candida in your mouth.
What is a try in denture?
Try-in initial denture set-up. Depending on clinician/technician preference this may be either an “ esthetic try-in” of just the maxillary anterior teeth (requiring an additional try-in) or the full set-up. Evaluate for accuracy of mounting, occlusal vertical dimension, esthetics and phonetics. Perform modifications as necessary. Patient and clinician should be satisfied before moving to next step.
Why should dentures be remounted?
Dentures should be remounted and equilibrated to compensate for errors in denture processing. Dentures should be returned finished and all external surfaces polished. Many clinicians will request clinical remount casts to be fabricated and returned with the case. Insert dentures and adjust as necessary.
What was the only treatment option available for completely edentulous patients?
Prior to the introduction of osseointegrated implants to dentistry, conventional complete removable dental prostheses were really the only treatment option available for completely edentulous patients.
Can dental implants be used for edentulous patients?
In addition, these steps should assist clinicians seeking to treat edentulous patients who are unwilling or unable to utilize implants.
How are dentures finished?
Each denture is hand finished using special burs to remove any excess acrylic around the edges and palatal area. The articulation is checked and adjusted if necessary.
How to make a denture with plaster?
The first step is to flask the denture by placing the model with the denture in the bottom flask securing it with plaster. When the plaster is dried, the upper flask is put in place and filled with additional plaster. The flask is then heated until the wax is sufficiently melter.
What is a denta lan?
The denta lan indexes and mounts the master casts created from the custom tray impression and the bite rim measurements using an articulator to represent the patient’s jaw relationship.
Why do bite rims need to be contoured?
The bite rims need to be contoured to provide the correct lip support and indicate future incisal edge positions, the occlusal plate, the vertical dimension and the midline.
What does a lab technician do with teeth?
Your lab technician will set up the teeth, in the desired occlusal scheme. Assuring proper form and function.
How to make a dental impression?
First, take a preliminary impression of the patient’s mouth using stock trays designed for edentulous patients. It may be necessary to enhance the tray periphery with wax. Pour the impression in dental stone using a vibrator to eliminate bubbles and voids. 2.
Can implants be used for edentulous patients?
Although dental implants are an increasingly popular treatment for restoring dentition in completely edentulous patients, not everyone desires or is suitable for this procedure. Conventional dentures still provide a predictable treatment outcome or may be required to help patients transition from dentures to implant-retained prostheses.
What technique is used to fabricate complete dentures?
Fabrication of Complete Dentures Using Neutral Zone Technique in a Patient with Severely Resorbed Alveolar Ridges - A Case Report
What is neutral zone in dentures?
Neutral zone should be recorded in severely resorbed mandibular ridge with altered neuromuscular control which involves only one extra clinical step in conventional denture making that is easy to manipulate. This will help in improving denture stability and will provide more comfort to the patient.
What material is used to record neutral zone?
[10]In this case report, condensation silicone was used to record neutral zone.
Can you preserve neutral zone?
The condensation silicone impression material was then removed from the base plate, the neutral zone space can be preserved using plaster index and molten modelling wax was flowed into the space created between the index that will take the shape of the moulded occlusal rim in neutral zone. (Figure 7) Similar procedure was done for moulding maxillary counterpart.
