1- Accuracy
of image-guided implantology DOWNLOAD.
Study compared accuracy of two
image-guided implant insertion devices (Robodent and IGI).
Machine-guided insertion was
significantly more accurate than manual implantation . . . accuracy of
manual is sufficient for most clinical situations.
2- Load-related
implant reaction of miniimplants used for orthodontic anchorage DOWNLOAD.
South Korea is currently very
active in use of implants for orthodontics . . . recent Nobelbiocare OnPlant
(HA coated) was not popular - lacked promotion . . . current technology is
essentially a pin which passes through and through alveolar ridge
(avoiding roots) - can be loaded immediately if fully inserted.
3- Prevalence
of subjects with progressive bone
loss at implants DOWNLOAD
Looked at number of patients
(not number of implants) with fixed prostheses only . . . progressive bone
loss defined as 3+ threads at five years, all implants were machined surface
. . . found that 30% of patients had PBL at 5+ years

Influence of platelet-rich plasma added to xenogenic bone grafts on bone
mineral density associated with dental implants. DOWNLOAD
Dog study: 9 dogs, 90 sites . .
. bottom line: No difference with or without PRP
5-
Dental implant failure rate and associated risk factors. DOWNLOAD
What are risk factors for
implants - some surprising results . . . highest risk factors: radiation
treatment, menopause AND receiving hormone replacement . . . surprisingly,
chemotherapy and steroid treatment LOWERED risk . . .

Stress analysis in edentulous mandibular bone supporting implant-retained 1
piece or multiple superstructures. DOWNLOAD
Model-based study . . . most
forces concentrated at crestal bone and implant apex areas . . . not much
force concentrated along length of implant . . . forces are greatest at
endpoints of FPD span - may explain why more failures are seen in
posterior

Impact of smoking on marginal bone loss. DOWNLOAD
Israeli study (25% of
population are smokers) - looked only at non-grafted sites . . . 60% were
immediate-placement . . . measurements were taken directly from panoramic
radiograph (accuracy?) . . . found more initial marginal bone loss in
smokers . . . comment: with a clean, closed surgical site = not much
difference between smokers and non-smokers

Peri-implant pathology caused by peri-apical lesion of an adjacet natural
tooth: a case report: DOWNLOAD
Pathology not visible on PA
radiograph will be visible on CBCT . . . maybe teeth adjacent to planned
implant sites should be routinely vitality tested prior to implant placement

Neurosensory disturbances following bone harvesting in the symphysis: a
prospective clinical study. DOWNLOAD
Swiss study . . . devitalizing
of teeth as well as loss of proprioreception is seen in cases where
horizontal incision is made for bone harvesting from symphysis . . . flap
design can be altered (as discovered by endodontists) to minimize these
potential sequelae . . . hard to justify harvesting of autogenous bone
from symphysis now that evidence shows equal success rate in sinus grafting
with non-autogenous sources
