Denture is a kind of prosthetic device that can replace missing teeth, and it often needs to be customized to meet everyone's unique oral morphology and needs. Partial denture refers to the place where the gap between teeth needs to be covered. Compared with the design of complete denture, it is more personalized and refined. Below I will introduce the drawing method of partial denture design in detail.
1, draw oral cavity model.
The design of partial denture needs to draw a model first, so as to measure and describe the shape, size and structure of the patient's mouth more accurately. In order to ensure a high-quality model, other kinds of software or tools (such as CAD or hand-drawing) can be used to complete the relevant drawings. Designers are usually required to show details such as the color, position and size of teeth in the model.
2. Marking and measurement
With the establishment of dental model, designers need to mark and measure to determine the key details such as the position, clearance angle and contact surface of denture. In particular, we should pay attention to the inspection of some dentures that are mainly in contact with neighbors' teeth to ensure the perfect connection between them without discomfort.
3. Select materials and components
Designers need to choose the required materials and components as appropriate, so as to ensure that all the variable elements cooperate with each other in the overall appearance and maintain the customized personality. Usually, due to the different oral conditions and preferences of different patients, the choice of components from the aspects of materials, techniques and details will affect the appearance and quality of the whole partial denture.
4. Annotation and completion
When all the elements are determined, the designer needs to annotate and mark the model so that others can easily understand the design. For example, color can be used to indicate the size and shape of teeth, and lines can be used to indicate the degree of inclination and the smoothness of gap angle.
In a word, partial denture design is a detailed process, involving complex technology and precise details. Correct drawing needs to consider the complexity of the patient's condition, follow the relevant medical norms and standards, and provide beautiful, high-quality and durable tooth replacement programs.
