Organizational structure of the practical classes

(Implementation of practical class plan):

At the beginning of the class a teacher calls the register and designates a student on duty, names the topic and purpose of the class, finds out unclear questions, which appeared during independent work of students.

Then the teacher analyzes subject questions, tasks of students’ research work and methods of practicing skills in accordance with the methodologic instruction, by means of actively questioning all students of the group.

The teacher is guided by the extent of knowledge obtained by the students during their independently studying the material in the textbooks, lecture notes and methodologic instructions, as well as preparing students’ research work in the albums for independent work.

Besides, the teacher can choose to check the hometask in oral or written form, as well as in mixed and oral-and-written form. The teacher can use situational tasks and test questions in addition to routine subject questions.

Having controlled the students’ knowledge for the class, the teacher demonstrates to the students methods of preparation and obtaining of a print thermoplastic impression material.

After the demonstration the students start to independently train practical skills on each other under supervision of a senior laboratory assistant or the teacher.

At the end of the class the teacher gives marks for oral answer or written work, for independent students’ work, signs the protocol of the laboratory work, as well as names the next topic and questions for study.

Summary

Relining: the procedures used to resurface the tissue side of a denture with new material, thus producing an accurate adaptation to the denture foundation area .

Relining is indicated when there is loos of retention or stability due to alteration or loos of correct relation ship to the supporting tissues. It cannot be done in the absence of optimum vertical and centric relation and correct occlusal form of teeth.

Why we do relining for a new denture ?

1- if the pt had a recent extractions .

2- incorrect impressions the dentist took .

When we do a relining for an old denture ?

1- if there loss of fit and retention due to increase bone resorption .

2- loss of VD of occlusion .

3- imbalance of occlusion ( disharmony ).

4- loss of facial support .

5- chewing insufficiency .

Objectives of relining :

1- improve retension and stability .

2- improve the appearance .

3- restoration of VD at occlusion .

4- restoration of eveness of occlusion.

5- comfort the pt and alleviate the pain .

Indications for relining :

1- resorption of the bone >>> poor fit of the denture .

2- immediate retention >> for pt with recent extractions .

3- senile pt ( chronic ill pt ) relining of the old one.

4- in repaired denture that had lots of fractures , history of lots of fractures that not accidently happen .

Indication for rebasing ( new base ) :

1- porous denture base.

2- long time of wearing the denture.

3- discolored denture base.

4- the pt can't afford the cost of a new denture .

Contraindications for relining :

1- poor esthetics of the denture , unsatisfactory appearance.

2- improper speech .

3- excessive resorption >> loss of stability and retention .

4- loss of fit (abused tissue ) diseased tissue .

Rebasing : the laboratory process of replacing the entire denture base material on an existing prosthesis .

Rebasing is indicated for porous denture base and in case of deficient acrylic during fabrication .However, it is contraindicated in case of incorrect jow relation.

Relining procedure

Direct Method:

The relining procedure can be done directly in the patient s mouth using selfcure acrylic resin. petrolum jelly is applied to the tissue surface and acrylic is lined on the tissue surface of the denture and stabilized in the mouth. The denture with the relining acrylic material is retrieved before the acrylic completely sets in order to prevent the damage to the oral tissues due to heat generated. the relined denture is trimmed to remove any excess material followed by finishing and polishing of the borders. This procedure is, however, proved to be a failure for the following reasons:

The relining material often produces a chemical burn.

The resulting reline is often porous and subsequently produces a bad odour.

If the denture is not positioned correctly, the material can not be easily removed in order to start again.

Since the denture with the relining material is retrieved from the surface before the complete curing of the acrylic, the denture may be distorted.
