3D finite elements analysis study aims to conduct a
biomechanical comparison between two cantilever’s lengths with two different
degrees of tilting the implants.
Objectives: The purpose of this study was to evaluate the influence of
glass fibers in strength acrylic resin fracture around a overdenture
abutment.
A model was designed to simulate the
clinical situation of an implant overdenture abutment (50-1
2-1.5mm).
thirty specimens were divided divided into 3 groups, ( 10 specimens
without glass fibers , 10 specimens with one glass fibers, 10
specimens with two glass fibers). All specimens were submitted to a
3-point bending test
Surgical placement of dental implants may cause a certain degree
of pain and discomfort to some patients. Conventional nonsteroidal
anti-inflammatory drugs have been widely used in the
control of postoperative pain, but sparse information is avail
able
about the efficacy of celecoxib, a selective cyclooxygenase-2
inhibitor, after surgical placement of dental implants.
The aim of this study was to compare the analgesic efficacy of
celecoxib and ibuprofen on pain control after the surgical
placement of dental implants .
The purpose of this research is to evaluate the possibility of implantation in chronic
periodontally infected sites The research sample comprised of 20 implants were placed in 6
patients from both sex , the sample were divided into 2 groups: the co
ntrol group, 10
implants were placed after waiting period of four months after the extraction and the test
group, 10 implants were immediately placed after extraction in areas of chronic
periodontally infected sites. Gingival index GI, marginal bone loss MBL, proping depth
PD, Implant survival, evaluated for both groups. The results of the present study showed
that the survival rate was 100% in control group and 80% in test group. There was no
statistical difference between the test and control regarding, GI, while there was statistical
difference between the test and control regarding MBL and PD during periods of follow
up.
The purpose of the present study was to radiologically assess the
hard tissue changes around the immediately loaded implants single
tooth bioactivated with plasma rich in growth factors ,placed in the
mandibular posterior region . Twenty dental im
plants placed in 13
patients had at least single edentulous space in the posterior
region of the mandible using single stage procedure after
bioactivation the implants surfaces with plasma rich in growth
factors.
the aim of our study is comparing
theretentive and stability forces between mandibular overdentures
retained by two implants and mandibular overdentures retained by
four implants by using ball attachments.
The aim of this study was to evaluat the influence of insertion torque on the survival of immediately placed single tooth implants and bone resorption process around it . Materials and methods : 8 healthy patients received 24 conical implants ( ID
I-BIO ) with sand blasted and acid etched surface . All implants inserted immediately in extraction sites, the sample were divided into two groups: The implants in the first group were inserted with insertion torque below 35 Ncm (mean 25 Ncm ) , while in the second group the implant were inserted with insertion torque above 35 Ncm (mean 52,2) .Implant survival and marginal bone loss MBL were evaluated after two , six and nine months for both groups .Results : four implants from the first group failed to osseointegrate, and statistical analysis of the data showed no correlation between insertion torque and peri- implant bone resorption .
Maxillary sinus augmentation is frequently necessary before placement of
dental implants in the posterior maxilla. Besides autogenous bone graft, various bone substitutes have
been used widely to augment the maxillary sinus,successful bone augmenta
tion in the maxillary sinus
without bone grafting and osseointegration of implants have been reported in several studies, recently,
successful bone reformation in the sinus using autologous platelet-rich fibrin (PRF) concentrateas an
alternative to bone grafting has been reported.
The aim of this study: was to assess the useof PRF clots and membranes as the sole filling material during
a lateral sinus lift with immediate implantation using radiologic exam (cone beam ct).
Background& Objective: The reduction of alveolar crestal bone density is one of the earlier signs of periimplant
disease and precedes the loss of height of the alveolar crest, because of that early detection of the
small changes in density is impor
tant and lead to the early onset of treatment and increases its success's
percentage.
This study aimed to evaluate the ability of the direct conventional digital method in detection of density
changes around dental implants by the mean value of the gray level of the histogram of the selected area
comparing with radiographic subtraction method.
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.
