Prótese Total para iniciantes Parte 4 - Montagem de Dentes Posteriores Inferiores

Introduction

This tutorial provides a step-by-step guide for beginners on how to assemble lower posterior teeth in dental prosthetics. Based on the insights from Leila Antony's instructional video, this guide aims to simplify the process for dental students and practitioners looking to enhance their skills in denture making.

Step 1: Gather Necessary Materials

Before beginning the assembly process, ensure you have all the required materials at hand. This includes:

• Lower denture base
• Posterior teeth (specific to the patient's needs)
• Dental wax
• Articulator
• Dental tools (e.g., spatula, wax knife)

Practical Tip: Organize your workspace to avoid misplacing any materials during the process.

Step 2: Prepare the Denture Base

Start by preparing the lower denture base:

1. Inspect the Base: Check for any defects or imperfections in the denture base.
2. Clean the Surface: Ensure the surface is clean and dry to allow for better adhesion of the teeth.
3. Warm the Base: If necessary, gently warm the base slightly to make it more pliable for adjustments.

Step 3: Position the Posterior Teeth

Now you will position the posterior teeth on the denture base:

1. Select Teeth: Choose the appropriate posterior teeth based on size, shape, and color.
2. Mark Positions: Lightly mark the intended positions on the denture base using a pencil or a similar marking tool.
3. Trial Placement: Place the teeth on the marked positions without securing them to check for alignment and aesthetics.

Common Pitfall: Ensure that the teeth are correctly oriented to maintain proper occlusion.

Step 4: Secure the Teeth in Place

Once the trial placement is satisfactory, proceed to secure the teeth:

1. Use Dental Wax: Apply a small amount of dental wax to the base of each tooth.
2. Press Firmly: Gently press each tooth down into the wax until it is secure.
3. Check Alignment: Use the articulator to verify that the teeth are positioned correctly in relation to the opposing dentition.

Step 5: Final Adjustments

Make any final adjustments to ensure the fit and function are optimal:

1. Check Occlusion: Ensure that the upper and lower teeth meet properly when the articulator is closed.
2. Make Corrections: If any teeth are misaligned, carefully remove them and reposition as needed.
3. Smooth Edges: Use a wax knife to smooth out any excess wax around the teeth.

Step 6: Review and Prepare for Finalization

After securing and adjusting the teeth, it’s time to review:

1. Inspect Overall Appearance: Check for uniformity and aesthetics.
2. Prepare for Next Steps: If satisfied, prepare the denture for final processing or send it for further adjustments to a dental lab.

Conclusion

This tutorial outlined the essential steps for assembling lower posterior teeth in a dental prosthetic. By following these steps, beginners can gain confidence in their skills. As a next step, consider practicing these techniques under supervision to refine your abilities and ensure successful outcomes in real-world applications.
