This prospective clinical trial aims to investigate the change of
alveolar ridge width after immediate implantation using tow
deferent techniques in expanding the alveolar ridge. In this
study, 12 patients (9 female,3 male) with narrow alveolar ri
dges
in the maxilla were treated. 20 dental implants were
immediately installed after the expansion procedures of the
selected narrow ridges , 10 implants with Bone Spreader
technique , and 10 implants with Bone Splitting technique .
The aim of the study was to compare the clinical and radiographic
changes between conventional implant and immediate implant
placement after tooth extraction. Ten patients of both sexes( 6male,4
female) included in this study were received 20 impl
ants. Each patient
received two implants in the posterior region of the mandible . Dental
implants were installed in the same surgical procedure , One of the
implants was placed immediately after tooth extraction (test group )
and the other one was placed 6 months after the extraction (control
group ) .
The purpose of this research is to study the effect of Subcrestal placement of dental
implants on marginal bone loss in immediate implantation. The research sample
comprised of 24 implants were immediately placed after extraction,12 implants have
placed at Equicrestal level (6 in the maxilla and 6 mandible) served as control group and
12 impalnts (6 in the maxilla and 6 mandible) have placed at Subcrestal level served as test
group. modified bleeding index MBI, probing pocket depth PPD and marginal bone loss
MBL Implant survival, evaluated for both groups. Mbl were 0.85 mm in control group and
1.30 mm in test group after one year of dental emplacement The results of the present
study showed that the success rate was 100% in both groups, there was no statistical
difference between the test and control regarding, MBI, while there was statistical
difference between the test and control regarding MBL, PPD. during periods of follow up .
