Question 1

What are the long-term treatment outcomes of single maxillary buccal peri-implant dehiscences? - 10 year prospective study

Roccuzzo et al. CIDRR

Answer 1

10-year prospective study
Examining peri-implant soft tissue dehiscences (PSTD’s)

16 patients
Treatment: CTG + CAF over implant soft tissue dehiscence.
There was no control group.

RESULTS:
The mean peri-implant mucosal recession decreased from 1.9 mm. Mean coverage was 90% at all follow-ups. Complete PSTD coverage was obtained in 58% of cases at 10 years.

Question 2

Describe the outcomes of ridge augmentation and 2-stage implant placement using either tooth roots or bone blocks

Schwarz et al CIDRR

Answer 2

Compared tooth root blocks vs. allograft blocks
* 13 tooth root blocks
* 14 autogenous bone blocks

Results:
Tooth roots and autogenous blocks had similar changes in mean BOP, PD, and mean recession values. There was also 100% survival of all implants.
There were no radiographic results

Question 3

How does KTW correlate with resolution of peri-implant mucositis? Prospective cohort study

Blasi et al CIDRR

Answer 3

Performed mechanical therapy on peri-implant mucositis implants.

Observed resolution of the mucositis and the peri-implant microbiome changes.

Prospective two-arm study with 6 mo followup
n=40 patients
* Narrow KT : < 2 mm
* Wide KT: ≥ 2 mm
KT was measured from the mid-buccal

RESULTS:
NSSD in almost all results, because both the narrow and wide KT implants had significant decreases in plaque, full mouth bleeding, full mouth probing, and suppuration.
* However, BOP = greater reduction for Wide KT implants, but no changes for narrow KT implants –> this could be because the narrow KT implants lacked attached gingiva, so probing induced BOP
