Study Notes
- The text discusses various factors affecting the fit and stability of complete dentures, particularly in the maxilla (upper jaw).
- Prominent midline sutures and bony undercuts in the maxilla can interfere with the posterior extension of the denture base.
- A hyperplastic, mobile anterior ridge in the maxilla offers minimal support and stability for the denture base.
- Palatal morphology in the maxilla can provide limited resistance to the vertical and horizontal movement of the denture base.
- The reduction of the post-malar space by the coronoid process during mandibular opening and/or excursive movements is relevant to the design of the denture base.
- Maxillary ridge morphology can be categorized as Types A, B, C, and D based on resistance to vertical and horizontal movement and presence or absence of tori and vestibules.
- Muscle attachments in the mandible can influence the fit and function of a complete denture and are classified as Types A, B, C, D, and E based on the amount and location of attached mucosa and muscle impingement.
- Maxillomandibular relationships can influence the design and fabrication of complete dentures and can be classified as Class I, II, III, and conditions requiring preprosthetic surgery.
- A prosthodontic diagnostic index (PDI) classification system and complete edentulism checklist are mentioned for assessing the complexity of complete denture cases.
- Factors such as bone height, ridge morphology, muscle attachments, maxillomandibular relationships, and various classifications systems are discussed in relation to complete denture design and fabrication.
- The text refers to specific studies and publications in the Journal of Prosthodontics for further information.
