COIR Jan - March Flashcards
Bouckaert (Cosyn)
61% more mucosal scarring in GBR group - but performed verticals and didnt in CTG
GBR vs CTG for buccal convexity (RCT)
35pts - 9M9F (GBR) vs 9M8F (CTG) - no verticals in CTG group - No hx of perio - Anterior - Minimum 6mm B-P bone - Seibert I
6mo, 1yr, 3yr follow up!
NSSD in BSP at any timepoint
Buccal bone: 1yr/3yr at 3mm
GBR: 2.2mm/1.9mm
CTG: 1.5mm/1.4mm
Buccal CT: 1yr/3yr at 3mm
GBR: 1.9mm/2.3mm
CTG: 2.5mm/2.3mm
NSSD Pink esthetic score
Stacchi
Does new bone vary at different sites after sinus aug based on Bucco-Palatal width and Residual bone height (RBH)
18pts
RBH 5mm+
BPW (at 10mm in sinus) 6mm+
CBCT at 6mo
Sinus is wider distal vs (17mm vs 11.3mm)
More Newly Formed Min Tissue in narrow areas (mesial): 11.6% vs 17.5%
Strong negative correlation between sinus width and new bone formation
No correlation between RBH and new bone formation
Almohandes (Carcuac, Berglundh, Abrahammson)
Assessment of bone levels after experimental periimplantitis
CBCT vs PA vs Histology
5 dogs - ligature induced Pi - treated w/ 4 different regenerative procedures - 6mo later CBCT, PA, Histo
NSSD
PA consistantly overestimated by 0.3-0.4mm
No standarization of defect morphology
No standarization of PA vertical or horiztonal angulation (Hausmann 1995 - up to 2mm error when combined vertical and horizontal)
Bitencourt
Morbidity after FGG harvest RCT w/ Photobiomodulation therapy
Gallium Alluminum Arsenide Semiconductor Diode Laser
Red-Infrared (660nm-808nm)
Imm, 6hrs, 24, 48, 72hrs
VAS for pain
Control: pain level didnt get lower over followup
Test: pain level significantly lower at every time
Test vs Control: NSSD
2.5x less post op pain releiver use in test group
SS acceleration of % wound closure at 7days (33% vs 21%)
PROMs
Significantly less patient morbidity reported by patients (General function/oral function…)
Lamperti (Hammerele, Thoma)
Cemented vs Screw Retained on Zirconia Abutments base
5yr follow up of RCT
23 patients made the 5yr follow up (13 vs 10)
position had to allow for both screw or cement retained
adjacent teeth
primary outcome was marginal bone loss
NSSD: CEM vs SCREW
MBL: -0.15 vs -0.23
Tech complications: 15.4% vs 15.4%
Stable clinical parameters
No standardization for abutment height
Small sample
Puisys (Linkevicius)
Immediate + CTG + temp vs EXT + CTG then Implant + GBR then Temp
Inclusion - intact socket walls (Elian Class I socket)
NSSD between test and control
Distal papilla had SSD, but 1.3 vs 1.7mm in immediate
Crest al bone levels improved in both groups (NSSD) from T3 (final resto) to T4 (12mo)
Chair time: 127 vs 259min
4mo vs 8mo
single surgery vs multiple
Estheics - same
Gasser (Hammerele, Thoma)
Interproximal contact loss at implants - 10yr follow up
Impressions taken, model scanned, computer analyzed
n=39 patients
80 implants
90 interproximal contacts
50% (45) lost contact at 10yrs
Open contact >0.1mm - SS increased PD (0.45mm)
BOP, MBL, not affected by open contact
Walter
RCT evaluating Astra vs Strauman after 8yrs
No standardization of implant depth
No standardization of surgical protocol (GBR when needed, etc)
No standarization of abutment height/prosthetic
Terrible study
Astra had better numbers
