OMFS EXAM 2 UPDATED QUESTIONS AND ANSWERS
bone morphogenic proteins - CORRECT ANSWER✅✅✅BMPs are multifunctional growth factors that
belong to the transforming growth factor b superfamily (TGFb)
50 diff types but BMP-2,4,6,7 and 9 play role in bone formation
BMP-2 is most potent growth factors that induce mesenchymal stem cell and osteoprogenitor cell
differentiation into osteoblasts
requirements of bone grafts survivability - CORRECT ANSWER✅✅✅osteocompetent cells
source of blood supply
immobility
soft tissue coverage
wound care after grafting - CORRECT ANSWER✅✅✅dont remove sutures for at least 2 weeks: 14-21
days
soft mechanical diet for 10 days
abx rec if putting in foreign body
gentle rinsing w local abx like chlorhexedine beg on day 4
may have some
"spitting" of particuate bone
BMP treated sockets have more swelling
, esthetic zone graftin - CORRECT ANSWER✅✅✅depending on degree of smile, esthetic zone may be
1st pm to 1st pm
maintenance of soft tissue papillae is super imp for esthetic results
requires use of thermoplastic appliance and ovate Pontic to shape/maintian tissue
goals: atruamtic. ext, maintain soft tissue controues, implant w immediate temproization
ridge preservaiton
socket grafted w mineralized particulate cortical-cancellous granules and a collagen sponge
used PRP tech w graft
soft tissues maintained by use of thermoformed appliance and ovate Pontic
healing=4mo
immediate temp allows for continued support of the soft tissues during implant integration
keep contours just full enough to support tissues
good polished margins
inter proximal cotnact=ok but keep tooth out of occlusion, centric and excursions
allow max implant to heal for 4 mo then proceed w final restoration
