The main aim of the Prosthodontics, Oclusion and Orophacial pain II curricular unit is to continue the student's induction into the field of prosthodontics, which began in the first semester, by covering content relating to fixed prosthetics, removable prosthetics, occlusion, materials and CAD-CAM. This curricular unit has the following objetives for the different components:
FIXED PROSTHODONTICS 

To acquire theoretical-practical and practical knowledge/competencies for executing tooth preparation in Fixed Prosthodontics and performing provisional restorations, impressions and cementations.

REMOVABLE PROSTHODONTICS

Learning of general concepts related to the rehabilitation of totally edentulous patients with removable dentures. The student should be able to establish a correct diagnosis and treatment planning for totally edentulous patients.

OCCLUSION 
Acquire Knowledge, for clinical application, about the therapy of temporomandibular disorders and auxiliary means of diagnosing temporomandibular disorders, in addition to occlusion concepts related to the vertical dimension of occlusion and semi-adjustable articulators.

MATERIALS 

Acquire theoretical knowledge essential for the ability to handle materials used in rehabilitative treatment.
CAD-CAM IN PROSTHODONTICS
Acquire knowledge of digital flows in prosthodontics with CAD-CAM technology. Principles of scanning, CAD design and manufacturing techniques with 3D printers and milling machines.

Students should be able to:

- execute appropriate tooth preparations, temporary restorations and impressions on fixed prostheses;

- establish a diagnosis and plan a clinical case of total removable prosthesis, and produce casts, record bases and wax rims;

- apply diagnostic aids and therapeutic options in patients with temporomandibular disorders;

- manipulate different prosthetic materials;
- apply CAD-CAM systems in daily prosthodontic practice.

This curricular unit has the following programme content for the different components it contains:
FIXED PROSTHODONTICS
Theoretical-practical: Teeth with endodontic treatment and immediate false stump posts; Temporary restorations. Practice: Dental preparation, on models, of anterior full crowns in ceramic; Teeth with endodontic treatment; Temporary restorations.

REMOVABLE PROSTHODONTICS

Theory: Diagnosis and rehabilitation of totally edentulous patients; Clinical and laboratory steps of removable complete denture fabrication.

Practical:Manufacture of base plates and articulation rollers for removable complete dentures. Teeth assembly and waxing.

OCCLUSION
Therapy of temporomandibular disorders; Vertical dimension of occlusion; Face bow and articulators; Assembling models on a semi-adjustable articulator; Auxiliary means of diagnosing temporomandibular disorders.

MATERIALS
Materials used in removable, fixed and occlusal prosthodontics. Different groups of materials classified according to their composition, properties and fields of application - from the clinic to the laboratory. Polymers, Metals, Ceramics and Cements. Materials used in prosthodontics and occlusion, namely: wax, godiva and acrylic resin.
CAD-CAM IN PROSTHODONTICS
Stages of the CAD/CAM process; Intraoral and extraoral scanning; Design software; Milling, sintering and 3D printers; CAD/CAM materials in dentistry.

FIXED PROSTHODONTICS
Theoretical-practical (TP) and laboratory Pratical (PL) classes : Live demonstration, Supervised practical training of tooth preparation in models. Distributed evaluation without final exam (theory exam/practical tests).

REMOVABLE PROSTHODONTICS
Theoretical classes and laboratory Pratical: planning of total prosthesis. Distributed evaluation with final exam.

OCCLUSION
Theoretical-practical  classes: theory lessons; Distributed evaluation with final exam.

MATERIALS
Theoretical-practical: theory lessons, demonstrations and materials manipulation. Distributed evaluation with final exam.
CAD-CAM IN PROSTHODONTICS
Theoretical-practical classes: theory lessons; Distributed evaluation with final exam.

Terms of frequency: Minimum attendance of 75% in TP and PL classes. 
Presentation of works as requested by professors (minimum precondition for distributed assessment and access to the final exam).

ATTENDANCE:
Theoretical-practical and PL classes - Registration by the teacher and/or computer system.

According to Regulation no. 40/2022 - Amendments to the
Regulation of the Student Worker Statute of the University of Porto, namely in its Article 8.º no. 2 - “Without prejudice to the provisions of paragraph b) of the previous paragraph, the student worker is not exempt from carrying out assessment acts, including distributed assessment, which are a minimum precondition for access to the final exam, if one exists and in
accordance with what is established in the respective
curricular unit form”.

Final classification:

A - Calculated by the weighted average of the marks in Fixed Prosthodontics (26.6%), Removable Prosthodontics (26.6%), Occlusion (26.6%), Materials (10.1%) and CAD-CAM (10.1%).

An insufficient mark (below 9.50) in 2 or more of these components in the continuous assessment implies failure of the curricular unit.
Insufficient marks (less than 8.00) in 1 or more of these components in the continuous assessment implies failure of the curricular unit.
An insufficient mark (equal to or greater than 8.00) in 1 of these components in the continuous assessment implies approval of the curricular unit with an overall final mark of 10.
The exam in the period of appeal in the same semester can include all the components or only the components with an insufficient mark. Assessment in the supplementary or special season includes a theoretical test and/or oral exam and a laboratory practical test.


B - A mark ≥17 in each component requires an oral exam (or a mark of 16 in that component).



C - If voluntary scientific work is carried out in groups of 1 to 3 students, their marks can be weighted by 10% in that component (the remaining 90% is the final mark for the component).

The teachers responsible for each component submit their final grade proposal to the course leader.

The partial assessment rules differ for the different components:
FIXED PROSTHESIS
1. Of all the FIXED PROSTHESIS work carried out in the pre-clinical practical classes, 1 of each type must be identified (student name, curricular unit, tooth and date) and handed in to the teachers responsible (minimum precondition for distributed assessment and access to the final exam).
2. A practical assessment test will be carried out, weighted at 50 per cent, with a minimum mark of 9.5.
3. A presential theoretical test, weighted at 50 per cent, with a minimum mark of 9.5.
4. Grades lower than those referred to in points 2 and 3 imply failure in the continuous assessment. The student must take the final exam (appeal period).

REMOVABLE PROSTHESIS
1. The assignments for the practical assessment of REMOVABLE PROSTHESIS must be handed in at the end of the last lesson relating to each assignment, duly identified and packaged - 50% weighting, with a minimum mark of 8.00 for each assignment and an average of no less than 9.50 (minimum precondition for distributed assessment and access to the final exam).
2. A presential theoretical test - 50% weighting, with a minimum mark of 9.50.
3. Grades lower than those referred to in points 1 and 2 imply failure in the continuous assessment. The student must take the final exam (appeal period).

OCLUSION
1. A presential theoretical test will be held in the last lesson - with a minimum mark of 9.50.
2. A mark lower than that referred to in point 1 implies failure in the continuous assessment. The student must take the final exam (appeal period).


MATERIALS
1. A presential theoretical test will be held - with a minimum mark of 9.50.
2. A mark lower than that referred to in point 1 implies failure in the continuous assessment. The student must take the final exam (appeal period).


CAD-CAM IN PROSTHODONTICS
1. A presential theoretical test will be taken - with a minimum mark of 9.5.
2. Insufficient marks imply failure in the continuous assessment. The student must take the final exam (appeal period).
