Question 1

Describe how different socket seals affect the bone - measured by histology and CBCT

Magrin et al. IJOMI

Answer 1

RCT
22 patients
Four groups:
* Control: spontaneous healing
* Collagen matrix (mucograft) + BioOss
* Collagen Membrane (Bio-Gide) + BioOss
* Palate punch graft + BioOss

Took trephine biopsy and CBCT 4-6 mo after grafting.

Results:
NSSD regarding buccal bone height, palatal bone height, bone ridge thickness.
SSD for ridge cross-sectional area.

Conclusion: NSSD between the groups - small sample sizes.

Question 2

Compare bovine pericardium membrane versus titanium mesh for horizontal ridge augmentation of the atrophic maxilla.

Abaza et al. IJOMI

Answer 2

RCT
20 patients
* Pericardium + 1:1 mix of BioOss + autogenous
* Ti mesh + 1:1 mix of BioOss + autogenous

Results:
SSD in % change in bone volume –> Pericardium is 31%, titanium mesh is 63%

However, NSSD in anything else.

Only 4 mo follow-up

Question 3

How does KT influence short dental implants?

Felice et al IJOMI

Answer 3

Parallel cohort retrospective study
110 patients with 217 implants.

NSSD between implants with adequate (2+mm) or non-adequate (<2mm) KTW.

Question 4

Does splinting vs. not splinting adjacent implants have any effects?

Yi et al IJOMI

Answer 4

Retrospective radiographic analysis
888 implants in total Placed from 2006- 2014 in Seoul National University Dental hospital

Results:
Biologic complications in 39% of implants and 41% patients

Mechanical complications in 50% of implants
* Screw loosening: 47%
* Fractures were most common in the abutments (13%)

Conclusion: Splinted implants have higher risk for biologic complications, but lower risk for mechanical ones.

Question 5

Describe how single immediate implant placement into anterior maxillary socket with facial bone defects fare over 5 years.

Zhao et al IJOMI

Answer 5

46 patients total
Sockets needed to have deficient buccal plate.
Immediate implants placed with GBR (using Hydroxyapatite “TianBo”, and membrane (Haiao)

CBCT taken at 0, 6mo, 5 years after surgery

Results: Examined bone loss over time
Labial bone thickness (LBT) changed by -0.5 mm over 5 years at all regions. Greatest change was -1mm at the implant platform at 5 years.

Average MBL: 0.7 mm on the mesial and distal (measured by PA’s)

Question 6

Describe the systematic review on preventative antibiotic therapy for sinus elevation

Salgado-Peraivo et al. IJOMI

Answer 6

Systematic Review
12 studies included

Result: NSSD for using vs. not using antibiotics for sinus elevation procedures

this was because “not enough evidence was available” to either support or disprove either group.
