|
Implant related (implant fracture)
Connection-related (loosening, fractures) Suprastructure-related (framework, veneer, loss of retention) |
|

|
|
List the types of mechanical complications
|
Caries in abutment
Loss of vitality Loss of retention Framework fracture Ceramic chipping or fracture Abutment tooth/ implant Loose abutment or screw |
|
|
What is the aetiology for fracture ceramic chipping or fracture?
|
Absence of periodontal ligament
Leading to loss of proprioception Dependence of mechanoreceptors in the surrounding bone (osseoperception) - difficulty in food location, control of force and direction, no reflex Patient factors: bruxism, hx of complications Technical factors: length of suprastructure, cantilever, screw vs cement |

|
|
|
|
|
|
|
What to look for during the clinical exam to Dx?
|
• Plaque assessment
• Mucosal conditions: Swelling, fistula, redness, etc. • Peri-implant probing depth/ attachment level: PPD≥5mm • Bleeding on Probing (BoP) • Radiographs |

Can a regular probing damage the peri-implant soft tissues?
|
Separations do occur but will restore in 5 to 7 days
|
|
|
What are the methods of management of peri-implant mucositis?
|
• Removal of suprastructure if possible
