INTRODUCTION

DESIRABLE OCCLUSAL CONTACT RELATIONSHIP FOR REMOVABLE PARTIAL DENTURES
3.Bilateral balanced occlusion in eccentric position should be formulated when a maxillary complete denture oppose the removable partial denture. This is a complete primarily to promote the stability of the complete denture.

4. Working side contact should be obtained for the mandibular distal extension denture. This contacts should occur simultaneously with working side contacts of the natural teeth to distribute the stress over the greatest possible area

5. Simultaneously working and balancing contact should be formulated for the maxillary bilateral distal extension removable partial denture whenever possibe.

 

 

 

8. Balanced contact of opposing posterior teeth in a straight forward protusive relationship and functional excursive position is desired only when an opposing complete denture or bilateral distal extension maxillary removable partial denture is placed.

 

9. Artificial posterior teeth should not be arranged further distally than the beginning of a sharp upward incline of the mandibular residual ridge or over the retromolar pad.

 

 

METHODS FOR ESTABLISHING OCCLUSSAL RELATIONSHIP

(B) INTEROCCLUSAL RECORS WITH POSTERIOR TEETH REMAINING

It should be replaced a second time to correct the distortion that result from chilling and than again chilled after removal.

All excess wax should now be removed with a sharp knife.

A wax record can be further corrected with a freely flowing occlusal registration material such as metallic oxide paste used as the final recording medium.

 

(C) OCCLUSAL RELATION USING OCCLUSION RIMS ON RECORD   BASES

METHOD FOR RECORDING CENTRIC RELATION ON RECORD BASE

(D) JAW RELATION RECORD MADE ENTIRELY ON OCCLUSION RIMS

3. After 24 hours the occlusal surface of the wax rim should show continuously gloss. Which indicate functional contact with opposing teeth in all extreme of movements.

Any are of deficient are add this time.

4. After a second 24- 48hours period of wear the registration should be complete and the acceptable.

The remaining teeth that serve as vertical stops should be in contact and the occlusal rim should show an intact glossary surface, representing all each cusp in all extremes of movements.

 

CONCLUSION

The balanced occlusion is the most important factor for the retention of the prosthesis.

The occlusion must be evaluate before the prosthesis fabrication start.

Preprosthetic mouth preparation must be done for better occlusion reproduction.

Proper method to be used for the record of correct occusion.

Imbalanced occlusion is the main cause of retention loss of the prosthesis.
