Mouth Preperation Flashcards
Fixed prosthodontic treatment is successful only if restorations are placed on ?
Caries-free
Well-restored teeth
In a healthy environment
As a general plan, treatment procedures should be performed in which sequence ?
- Relief of symptoms (chief complaint)
- Removal of causes (e.g., excavation of caries, calculus removal)
- Repair of damage
- Maintenance of dental health
What’s tooth removal strategies ?
- is the elimination of teeth that are hopelessly involved periodontally or are nonrestorable
- Early extraction of teeth and/or roots allows the socket areas to heal and can provide better access for plaque control of adjacent tooth surfaces
How to stibalize mobile teeth ?
Depending on the patient’s need, the teeth may also be treated by splinting with provisional restorations
What’s tooth loss etiology ?
Progressive reduction in the residual alveolar ridges
Due to alveolar bone resorption
Relatively rapidly in the first year after tooth loss
Slower for next years
Greater extent in the mandible compared with the maxilla
Quantitative and qualitative reduction of the alveolar bone
What’s Anatomical Indication for grafting ?
Vertical bone deficiency
Horizontal bone deficiency
Local bone defect
What’s Clinical Indication for grafting ?
Inadequate bone volume for reliable implant insertion
Excessive risk of intra- or postoperative mandibular fracture
What’s socket preservation?
A procedure that reduces bone and soft tissue loss after tooth extraction
It is performed immediately after tooth extraction
Placing a bone graft into the socket
Results in greater orofacial dimension of bone
Compensates for the biologic resorption of the facial bone wall
Can reduce the need for later bone augmentation
What’s socket preservation results ?
Results in greater orofacial dimension of bone
Compensates for the biologic resorption of the facial bone wall
Can reduce the need for later bone augmentation
Socket preservation indications ?
Improve the appearance of the remaining teeth and gums
The placement of an implant at a site with a thin crestal ridge could result in a significant buccal dehiscence
Socket preservation should be considered when:
Implant placement needs to be delayed
When implant placement for some reason needs to be postponed for more than months
Future fixed partial denture pontic site is planned
Which bone graft biomaterial has this properties ?
Closest to the ideal grafting material
The gold standard for the bone regeneration
Osteoinductive abilities
Osteogenic abilities
Total osteocompatibility
In the graft there are cells and proteins able to induce the differentiation of the preosteoblasts
Autologous grafts. ( from same individual )
Which bone graft material obtained from animals… ?
Xenograft
Which bone graft most suspectible to transmit diseases ?
Allograft
Material from synthetic origin such as calcium phosphates, glassceramics and polymers
The biggest challenge - reproducing the surface characteristics of biologically derived materials
The degradation may be modified by changing the material’s chemical structure
Which bone graft ?
Alloplast
In which situations we most extract the tooth ?
- Perio disease
- Root fracture
- Over crowding to no damage the adjacent
- Impacted teeth
