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

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.

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.

Explain the difference between the factors that affect occlusion (comparing) natural teeth to artificial teeth

See S. Winkler

Example: artificial teeth are attached to one denture base for each arch and move as one unit, which means it is easily displaced by dislodging forces. Natural teeth move independently and migrate slowly into a favorable occlusion.

Post your comments for the rest of the factors.

To conclude discussion on immediate dentures and how youu would analyse the model for the denture design to allow comfortable insertion of the denture in the mouth by the dentist

When  preparing a model for an immediate denturre and considering comfortable insertion of the denture, the technician needs to consider the undercut present and avalaible for retention. When the undercut is less than 1 to 2mm it is of no great significance because of the compressibility of the soft  tissue and this compressibility will allow for the insertion of the denture. Undercuts composed entirely of soft tissue, as in the tuberosity areas, can be utilised for retention and will still be able to be inserted comfortably into the patients mouth.

With undercuts greater than 2mm, analysis of the model would indicate where the flange should be relieved or shortened. Vertical relief refers to the shortening ofthe flange (half flange) to avoid it entering the undercut area. Horizontal relief  refers to a modification of a fully extended flange so that the  degree  of horizontal undercut engaged is reduced. A shortened or part flange is indicated  in the anterior region where in the interests of conservation of alveolar bone it is considered undersirable to create room for a complete flange by alveoloplasty. Provided a part flange gives adequate retention of the denture it is in general to be preferred to excessive horizontal relief of a flange in order to allow the denture to reach the sulcus beyond a deep undercut area. As a result of  horizontal relief of the border becomes thin and sharp,this could cause trauma to the sulcus. This situation is particularly so in the case of the mandibular denture, where the foundation is triangular when cross-sected. In this situation the denture tends to sink as a result of bone resorbtion during the first few months of extraction.

When creating horizontal relief the dental technician would need  to block out the appropriate areas on the model with plaster, after surveying. When doing this the technician might be required to thicken the flange in order to avoid the flange becoming a knife-edge.
