Study Notes
Upper Anterior Teeth Length
- The length of upper anterior teeth is controlled by the vertical dimension of occlusion (VDO).
- Short lips result in only the incisal edge of the upper central incisor being visible.
Width of Upper Central Incisors
- The width of the upper central incisors is determined by the width of the inter-canine space.
Lower Anterior Teeth Alignment
- The length of the lower anterior teeth should be aligned such that they do not protrude beyond the upper incisal edges when the teeth are in occlusion.
Posterior Teeth Esthetics
- Posterior teeth with a cusp height of 2-3mm are generally considered more esthetic due to their natural appearance.
Esthetic Occlusion
- For patients with esthetic concerns, balanced occlusion can be achieved using posterior teeth with a cusp height of 2-3mm.
Cuspal Angulation
- Cuspal angulation refers to the angle of the cusp slopes on posterior artificial teeth. This angle affects the path of occlusion and can impact function and wear.
Posterior Teeth for Weak Ridges
- Posterior teeth with a lower cusp height (less than 2mm) should be selected for patients with weak ridges to prevent excessive pressure and denture dislodgment.
Bucco-Lingual Width
- The bucco-lingual width of posterior artificial teeth should be narrower than natural teeth to avoid impinging on the cheeks and tongue.
Maxillary Premolar and Canine Length
- The length of the maxillary first premolar should be slightly shorter than the maxillary canine to maintain proper esthetic effect and a balanced appearance.
Denture Dislodgement
- To prevent denture dislodgement, it's crucial to avoid excessive horizontal and vertical forces during occlusion, which can be achieved by using balanced occlusion principles and appropriate cusp heights.
Occluso-Gingival Height of Posterior Teeth
- The occluso-gingival height or length of posterior teeth is primarily controlled by the vertical dimension of occlusion (VDO).
