The aim of the study was to evaluate the influence of the mucosal tissue thickness on the crestal bone resorption around dental implants during a year of follow-up. Nine patients of both sexes included in this study received 24 implants. Patients in
the sample were divided into two groups: group I (mucosa above 2 mm, and 12 implants), and group II (mucosa up to 2 mm, and 12 implants). Implants in each group were divided into two groups: a control where 6 implants were placed at the crest level, and a test where (6) implants were placed 2mm supracrestally. The results revealed that there was an increase in crestal bone loss in group 2 with statistically significant differences. To conclude, the initial thickness of mucosa at the time of implant placement affects crestal bone loss; increased bon loss occurs when the tissue thickness is 2 mm or less at the time of implant placement.
The aim of this clinical study Was to Evaluation success
rate of the Bone Augmentation With Simultaneous Dental
Implantation using Autogenous Bone Block In Patients With
Atrophic Alveolar Ridges .
The study was contained 6 cases were augmented Wi
th
Simultaneous Dental Implantation by applying Autogenous
Bone Block technique The height and width was measured by
using computerized tomographic C T scan before and after
the surgical operation and also resorption after six months.
the purpose of this study to evaluate early implant success of small-diameter
2.5mm one-stage dental implants immediately loading in congenital missing of maxillary lateral incisor
cases associated with limited interdental space and mesial and distal bone loss after one year of loading.
Existing bone loss still remains an important challenge when implant placement
is required to rehabilitate the compromised site. A new way to place dental implants in cases of alveolar
atrophy, described in some articles, is the ridge-splitting tec
hnique, which allows the ridge to be widened
by a less invasive procedure than the traditional grafting approaches. The aim of this study is to evaluate
the efficiency of this technique in bone augmentation, evaluate the relationship between peri-implant
alveolar bone loss after Use of the Bone Splitting Technique, and to study the alveolar ridge width before
and after split.
Objective: The purpose of this randomized، double-blind،controled trial was to
evaluate the clinical and radiographic effects of 0.12% chlorhexidine digluconate gel on
peri-implant (hard and soft tissues surrounding the implant) maintenance.
Mater
ial and methods: Forty patients (80 implants) who received two implants at
least were randomly assigned to two groups: 0.12% chlorhexidine digluconate gel as test
group، and placebo without CHX as control group. Clinical and radiographic parameters
were recorded at day 10، month 2، 4، and 6.
Results: All clinical parameters except PPD showed better results in test group which
had statistically significant reductions (P< 0.05) in modified plaque index، modified
gingival index، modified bleeding index and attachment level compared to the placebo
group. There were no significant differences between groups in probing pocket depth or
radiographic parameter.
Conclusions: The results of this clinical study indicate that twice daily use of 0.12%
chlorhexidine digluconate gel may enhance the peri-implant maintenance.
The initial retention of implant-supported removable partial
dentures(ISRPD) is unknown. the purpose of this in vitro study was
to compare maximum dislodging forces of distal extension
mandibular ISRPD with three different clasp design. a stimulat
ed
class 1 partially edentulous mandible was prepared with two
implant in the first molar regions and two metal ceramic on distal
abutments. Fifteen bilateral distal extension frameworks was
fabricated with three different clasp design (Akers, I bar clasp ,no
clasp),each specimen was subjected to three type of retention
pulls ( main ,unilateral ,posterior pulls) five time with universal
testing machine.
