s10 - principles of proshtodontics Flashcards
- What impact does the aging population have on the need for dental implants?
The increasing life expectancy means more elderly patients, leading to a greater demand for dental implants as a long-term solution.
- How does age-related tooth loss affect implant needs?
As people age, tooth loss increases, leading to a higher need for stable and functional tooth replacement options like implants.
- What are the anatomic consequences of edentulism?
Edentulism causes bone loss in both width and height due to the lack of tooth stimulation, leading to structural changes in the jaw.
- How does tooth loss psychologically affect patients?
Missing teeth, especially front teeth, can significantly impact a patient’s self-esteem, confidence, and social interactions.
- What are the limitations of conventional prostheses in comparison to implants?
Removable dentures often have poor retention, comfort, and may reduce taste sensation, while implants offer more stability and comfort.
- What are the long-term success rates of implant-supported prostheses?
Implants have a high success rate, offering long-term stability and predictability compared to conventional prostheses.
- How do implants improve a patient’s quality of life?
Implants enhance comfort, esthetics, speech, and function, leading to greater patient satisfaction and confidence.
- What is the effect of edentulism on alveolar bone?
After tooth loss, there is a 25% decrease in bone width and up to 4mm loss in bone height during the first year.
- What happens to the mucosa after tooth loss?
The mucosa thins and the keratinized mucosa decreases, reducing the support for prostheses.
- How do bony structures change after edentulism?
Prominent bony structures such as the mylohyoid ridge and genial tubercles become more visible due to bone loss.
- How does edentulism affect neurological function?
Bone loss can expose the mandibular canal, causing paraesthesia and other sensory issues in the jaw.
- Why does prosthesis stability decrease with edentulism?
Prostheses may move or tilt due to muscle contraction and changes in bone structure, reducing their effectiveness.
- How does the tongue adapt after tooth loss?
The tongue may enlarge and take on a more active role in mastication, compensating for the loss of teeth.
- What esthetic problems arise due to edentulism?
Bone loss can cause a collapse of the lower third of the face, leading to an aged appearance.
- How does implant placement help preserve bone?
Implants provide functional stimulation, preventing bone resorption and maintaining bone structure.
- What role do implants play in maintaining occlusal vertical dimension?
Implants help preserve the vertical dimension of occlusion, maintaining facial esthetics and jaw relationships.
- How do implants improve occlusion and function?
Implants offer better occlusion and improved chewing efficiency by providing stable support for prostheses.
- What are the esthetic benefits of implant-supported prostheses?
Implants support natural tooth positioning, improve facial esthetics, and enhance patient self-esteem.
- How do implants improve speech and comfort compared to conventional dentures?
Implants improve phonetics by eliminating the need for a bulky palatal coverage and provide better comfort.
- What is the success rate of implant-supported prostheses?
Implant-supported prostheses have a high success rate, providing a more durable and stable solution than removable prostheses.
- How do implants support facial muscles and improve function?
Implants help maintain the function of masticatory muscles and facial expressions, supporting overall facial structure.
