Dental Implants

STUDY
PLAY
Implant fixture
the potrion of the implant that is surgicallypalced into the bone
acts as the root of the implant
made of titanium
screw=more interface
Titanium
biocompatible
poor conductor or heat and electricity
but scratches easily
Transgingival abutment post
titanium post that protrudes through the tissue into the mouth
supports the restorative prosthesis
Peri-implant tissues
tissues that surround the dental implant
Osseointegration
the direct contact of the bone with the implant surface
no PDL
3-6 months mand
6-9 maxillary
Junctional epithelium
attaches to the implant surface with LGE
Connective Tissue fibers
run parallel or circular to implant surface
Periodontal ligament and cementum
absent
Alveolar bone
in direct contact with the implant surface
Endosseous
placed into alveolar bone/basal bone—protrudes thru mucoperiosteum
most widely used
most predictable
titanium screws
must have enouch depth and width
use CAT scan
Subperiosteal
placed on the surface of bone beneath the periosteum
Mini implant
less width
not bone graft compatible
ortho
Peri-implant gingivitis
plaque-induced gingivitis
Peri-implantitis
chronic periodontitis
loss of bone
beyond 2nd thread
Self-care
Dental floss
Tufted Floss/toothpick in a holder for larger embrasure spaces and into sulci
(Soft orangewood toothpicks like a Stim-u-dent are preferred)
Nylon coated interdental brush
End-tuft toothbrush (can be dipped in Listerine or Chlorhexadine)
Oral irrigator used on low setting; NOT directed into down into gingival sulcus; following brushing/flossing
no metal
Bacteria in peri-implantitis
Porphyromonas gingivalis
Prevotella intermedia
Fusobacterium nucleatum
Occlusion
no PDL
Healthy gingiva
firm pink tissue
no mobility
no bone loss
Diseased ginigva
red, swollen
mobility
radiolucency
Probing
no probing necessary if healthy
gentle pressure
allow enough time for osseointegration
