To conclude Incisal guidance

This is influenced by the contacting surfaces of the mandibular and maxillary anterior teeth on mandibular movements. There are limitatons which influence the anlge of the Incisal guidance;
- ridge relation
- arch shape
- ridge fulness
- interridge space
- aesthetics and phonetics

Elaaborated on in Essentials of Prosthodontics by S. WInkler, between chapters 10 and 15

You will also find the information required on the topic Compensating curve.
The information provided here is some of the information needed you will find the rest in Winkler book.

Have fun. Good luck

To conclude - The type of posterior teeth used in lingualised occlusion for setting up complete dentures in balanced or non-balanced arrangement

LIngualised occlusion uses the maxillary lingual cusp as the dominant functional element, occluding against the corresponding portion of the mandiblar tooth. The posterior teeth selected for a lingualized occlusion differ depending on whethera balanced or non-balanced (monoplane type) arrangement is used. A balanced scheme usually involves a maxillary tooth with a sharply pointed lingual cusp to oppose a mandibular tooth with an uncomplicated occlusal table including only shallow inclines. For the no-balanced lingualized occlusion a monoplane mandibular denture tooth is selected. Porcelain teeth often are selected on the maxillary arch to maintain the sharpness of the lingual cusp; however, with the improved cross-linked resin denture teeth this may not be a problem. Numerous materials and designs have been suggested, although virtually any teeth can be used and may be customised by selective grinding to meet the needs of the patient. This is some of the information you will require. Other points was discussed in class lecture

To conclude - Why Lingualised Occlusion

Lingualised occlusion is a valuable occlusal concept, because it is adaptable to so many different clinical situations. LIngualised occlusion blends many of the ideals of the anatomic and mechanical schools of thought. For most cases it is entirely appropriate because a denture isa rigid piece of denture resin that must be acceptable anatomically while functioning under the mechanical and physical laws of the constantly changing oral envronment.
LIngualised occlusion is a simple occlusal scheme to teach and to learn. It can be modified to fit many different situations including any in which fully balanced anatomic teeth can be used and in all situations when non-anatomical teeth are used in balanced or non-balanced schemes. It may be used with complete and partial dentures, overdentures, immediate dentures and transitional dentures.

Type of teeth used for lingualized occlusion

Lets discuss the types of teeth we could use for lingualized occlusion for complete dentures, both in balanced or non-balanced occlusion.

Lingualized occlusion uses the maxillary lingual cusp as the dominant functional element which occludes against the corresponding portion of the mandibular tooth. The type of teeth selected for this type of occlusion can differ depending on whether you, the dental technician, is doing a balanced or a non-balanced occlusion arrangement.

Continue with the discussion....... Thank you.

Why Lingualised occlusion

Give reasons why you would consider using lingualised occlusion as an occlusal concept for complete dentures.

We have discussed this matter in one of our lectures. One reason could be because the patient has a severely resorbed mandibular ridge, this type of occlusal concept is considered to be ideal for this type of situation. This mainly because it is adaptable to so many different clinical situations.

Please continue with the discussion and points of view.
