Regardless of the mode of delivery, represent a guide to the relative teaching time and student effort required to successfully achieve a particular competency/module. This may include not only scheduled classes or workplace visits but also the amount of effort required to undertake, evaluate and complete all assessment requirements, including any non-classroom activities.

Pre-requisites and Co-requisites

Assumed knowledge and skills from the successful completion of the Diploma of Dental Technology.

Course Description

This unit applies to work in dental prosthetics where the dental prosthetist must enter into a structured professional relationship with a dentist as defined by the Dental Board of Australia before providing such treatment. 

This unit of competency describes the skills and knowledge required to construct and place an aesthetic, and functional implant retained overdenture.

Learning Outcomes


On completion of this course, you should be able to:

1. Plan treatment 

2. Take a primary impression 

3. Prepare to take a final impression 

4. Take the final impression

5. Pour master and/or working models and fabricate occlusal rims

6. Record jaw relationships and occlusion

7. Select appropriate artificial teeth

8. Fit and evaluate try-in prosthesis

9. Process, evaluate and insert the completed overdenture          

 

 


Details of Learning Activities

You will be required to make two implant retained overdentures for this unit, utilizing two different types of implant systems.

There are two ways of making an implant overdenture. The direct and indirect techiniques.

Majority of the the steps are pretty much the same for both the difference is either picking up the housing utilizing the actual finished denture or taking an impression with the impression copings and attaching the housing on the model.

1:Plan treatment plan for implant retained overdentures, including gathering appropriate data for case

2: Write referrals to appropriate dental surgeon

2. Take a primary impression using stock trays prior to implant placement

3. Prepare to take  final impression by fabricating special trays on primary models

4. Take the final impression utilizing the special trays made

5. Pour master and/or working models and fabricate occlusal rims

6. Record jaw relationships and occlusion

7. Select appropriate artificial teeth and tooth shade

8. Fit and evaluate try-in prosthesis

9. Process, evaluate and insert the completed denture    

10: Fabricate surgical stent by copying final denture and replicating in clear acrylic for dental surgeon to use as a guide

Overview of Assessment

The candidate must show evidence of the ability to complete tasks outlined in elements and performance criteria of this unit, manage tasks and manage contingencies in the context of the job role. There must be evidence that the candidate has:

• performed the activities outlined in the performance criteria of this unit during a period of at least 240 hours of work in a clinical dental workplace environment

• prepared 2 patients for insertion of an implant retained overdenture

• followed procedures to ensure patient safety during try-in and insertion

• constructed 2 functional and aesthetic implant retained overdentures.

To be deemed competent you must demonstrate an understanding of all aspects required of the competency.   Regular attendance is necessary.  Assessment methods have been designed to measure your achievement of each competency in a flexible manner over multiple tasks and consist of theory and practical based tasks.
