JCP Apr - Jun 2022 Flashcards
Cortellini & Tonetti
10yr follow up of RCT
M-MIST vs M-MIST/EMD vs M-MIST/EMD/DBBM
Tooth retention, recurrence, cost
NSSD between groups from 1-10yrs for retention/recurrence
Lower cost for M-MIST alone (no biomaterials)
At 1 year, using DBBM had significantly more bone fill by ~2mm vs MMIST, and 1mm vs MMIST EMD
Funded by EMD
Re-treatments performed as necessary?
Park et al (Thoma)
Impact of membrane fixation on ridge volume a nd new bone volume
2 types of collagen membranes (CM1 - porcine peritoneum derived - moldable and rougher/fibrous surface)(CM2 - porcine tendon derived - stiff smooth surface)
Fixed vs Unfixed
Fixation had no impact on volume
**Augmented tissue width AT CREST (0mm)
CM1Fixed: 2.4mm
CM1Unfixed: 2.4mm
CM2Fixed: 2.3mm
CM2Unfixed: 1.5mm
More new bone volume and % in CM1 vs CM2
Rougher surface may improve integration (noted greater tissue integration and fibrous encapsulation)
Guglielmi et al (de Sanctis)
Immediate implant + CTG vs Immediate implant alone 6mo RCT
Inclusion - no more than 3mm dehisence and must be anterior
NSSD in vertical bone changes
SSD in horizontal bone changes - favor CTG (-2.09 vs -1.16mm)
Change in Soft tissue volume: 6.7mm^3 vs 0.16mm^3
Change in Soft tissue Thickness:
Measured apico-coronal for 5mm
CTG: 1.33 to 2.42mm
IIP: -0.16 to 0.88mm
Pitman et al. (Cosyn)
IIP (24hrs) with immediate (72hrs), early/delayed (6wks+) provisional - systematic review and meta analysis
323 implants in 323 patients reviewed
NSSD in soft tissue or hard tissue changes
BUT - SSD LESS midfacial recession with IP when theres an intact alveoli: 0.87mm
NSSD if non-intact
Low strength of evidence - need more RCT
Cosyn et al.
CTG vs CMX for buccal thickness on single implants
Pre-op/Post-op/3mo/12mo
Digital scan/subtraction
Inclusion: at least 5mm KG
Baseline:
CTG: 1.4mm
CMX: 1.9mm
Amount of shrinkage:
Over course of 1yr, CTG had ~0.45mm resorption, CMX had ~1.35mm resorption
90% CTG and only 10% CMX had >0.75mm increased volume at area of interest
MBL: SSD
CTG: 0.66mm
CMX: 1.05mm
At 3mo:
CTG: -0.27mm
CMX: -1.05mm
From 3-12mo
CTG: -0.18
CMX: -0.28
Gotfredson (Stavrapolous)
Effcacy/risk of RPD in perio patients - systematic review
2 Retrospectives 5 prospectives
No strong evidence that RPDs increase risk of tooth loss
Increased plaque accumulation
Improved OHRQoL
No significant improvement in masticatory function (chewing time/force/strokes/etc) or nutritional status vs short dental arch
Ying-Shan Yu
Association between Periodontitis and Tinnitis - population based cohort study in Taiwan
Retrospective matched cohort - looked at National health insurance research database
Matched age/sex/follow-up
G1: 11,000 Perio patients that received treatment
G2: 11,000 Perio patients w/ no treatment
G3: 11,000 non-perio patients
G1: 412 w/ Tinnitus (aHR: 1.71)
G2: 404 w/ Tinnitus (aHR: 1.64)
G3: 321 w/ Tinnitus
Earlier onset in G1 and G2
Significantly more in G1 and G2
NSSD between G1 and G2
Its associated! - but, didnt control for smoking/systemic issues… more investigation needed
