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 complete 2 Implant retained overdentures for this unit utilizing two different types of implant systems.

 

You will need to demonstrate the following for 2 patients while being observed by an assessor

 

 

Construct a new set of conventional dentures for two patients

 

For the two patients you must:

 

1: Plan Treatment

2 Take a primary impression

3:Pour working model

4:Construct edentulous special tray

5:Take final impression

6: Pour master/working models and fabricate occlusal rims

7: record jaw relationships and occlusion

8: fit and evaluate try in prosthesis

9: Process, evaluate and insert the completed prosthesis

10: Construct surgical guide/stent  

 

Note: Due to the low availability of implant patients for this part of the procedure you will use a simulated model as your patient, although real dental clinic and laboratory conditions will be used along with real people presenting as supervisors and practitioners.   

 

1: Plan treatment for implant overdenture

2: Take final impression 

3: Pour master/working models 

4: Process, evaluate and insert the completed overdenture

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.

  

 

 


Assessment Tasks

Assessment 1 - Knowledge                     

  • Written Assessment to be completed online via CANVAS

 

Assessment 2 - Practical 

The following assessment tasks are to be completed for 2 implant retained overdentures

1:

For the two patients the student must construct a new set or conventional dentures:

a: Plan Treatment

b:Take a primary impression

c: Pour master/working models and fabricate occlusal rims

d: Record jaw relationships and occlusion

e: Fit and evaluate try in prosthesis

f: Process, evaluate and insert the completed prosthesis

g: Construct surgical stent/guide 

 

2:

The students existing 2 patients from Task 1 have decided they are not satisfied with the retention and stability of the conventional dentures. They are to construct a new set of removable implant retained overdentures

Note: Due to the low availability of implant patients for this part of the procedure the student must use a simulated model as their patient, although real dental clinic and laboratory conditions will be used along with real people presenting as supervisors and practitioners. 

a: Plan treatment for implant overdenture

b: Attach implant impression copings to abutments

c:  Take final impression 

d: Attach implant analogues to impression copings

e: Pour master/working models 

f: Process, evaluate and insert the completed overdenture
