Tx of Partial Edentulism Flashcards
What does survival of restoration mean?
Restoration still in mouth at time of exam - state of prosthesis or pt satisfaction ignored
What does success of restoration mean
Restoration in mouth w/ satisfactory function, meets pt and clinical standards
Survival rate of partial denture at 10 years and 5 years?
50-70% at 10 years
75% at 5 years
Survival of fixed-fixed conventional bridge after 10 years?
90%
Survival of conventional bridge after 10 years?
80%
Survival rate of RBB after 10 years?
80%
Survival PFM crown 10 years?
96%
Survival implant after 10 years?
96%
How does PAP impact success of RCT?
PAP reduced chance of success by 50% - reduced by 14% for every 1mm of increasing size
How is success affected if RCT is short?
Lowered 12% for every 1mm short apex
What reduces success RCT?
Long root filling
Perforation
Sinus/ PAP
Irrigation CHX
What increases success RCT?
Good coronal seal
Why shouldn’t provide cantilever bridge to RCT’d tooth?
Root treated teeth more prone fracture cervical margin - risk more significant when cantilevered
What is tooth restoratibiltiy index?
Assessment of amount of remaining coronal tissue
What is critical when providing resistance and retention to a crown?
A ferrule of at least 2-3mm
What is a key factors to consider when providing prosthesis?
Periodontal health and occlusal assessment
What happen if poor periodontal health?
Inappropriate support leading to mobility and failure of rigid abutments etc
What should be included in occlusal assessment?
Occlusal contacts, guidance patterns and identify occlusal anomalies
Risk w/ partial dentures in absence good OHI
root caries - increased risk
Accumulate plaque and predispose to gingivitis
% of pt w/ implants will suffer w/ mucosiitis or peri-implantitis?
Peri-mucositis = 60% Peri-implantitis = 20%
What is intervention for peri-implantitis?
Open flap debridement
Advantage of overdentures?
Retain proprioception Improved stability and retention Maintain alveolar bone heigh Psychological benefit Increased biting force/ accuracy
What should pt be aware of prior implant surgery?
Normally two surgeries needed
May want sedation
Grafting may be required
Then need rehabilitation and maintenance
What are some implant complications?
Bone loss
Screw or abutment loosening
Loss of retention
Fracture of veneering material
