25 slides from Dentsply Sirona's technical presentation, Aug 13, 2019
Slide 1: Class I, II, III Ridge Relationships
Class I, II, III Ridge Relationships for complete denture tooth selection and arrangement
Slide 2: Skeletal Class I Ridge Relationship
Skeletal Class I Ridge Relationship Class I (normal): The maxillary alveolar ridge crest is directly above the mandibular ridge. This is usually the most favorable ridge relation for complete dentures. Class I patients have moderate mandibular horizontal range of movement.
Slide 3: Skeletal Class II Ridge Relationship
Skeletal Class II Ridge Relationship Class II (retrognathic): The mandibular ridge is narrower and shorter than the maxillary ridge. In some instances it may be as wide as the maxillae in the posterior. Class II patients will have the most mandibular horizontal range of movement that makes balanced
Slide 4: Skeletal Class III Ridge Relationship
Skeletal Class III Ridge Relationship Class III (prognathic): The mandible is longer and wider than the maxillae. Such patients rarely show excessive jaw excursions but a straight opening and closing mandibular movement. Class III cases have no mandibular horizontal range of movement and posterior o

Slide 8: Rules for Class I Tooth Arrangement: Mandibular Posteriors
Rules for Class I Tooth Arrangement Mandibular Posteriors (Function) Teeth should be set in a straight line from distal of canine to retromolar pads Central fossae should be set over ridge crest (Pounds Line) Lingual surface of posterior teeth should be in line with medial of retromolar pads Occlusa
