تعيق الحافة السنخية الممتصة غرس الزرعات السنية بالشكل الأمثل. يعد توسيع الحافة السنخية بتقنية الفلع من الطرائق السريعة في معالجة نقص عرض الحافة السنخية. هدف هذا البحث بتقنية فلع العظم إلى تقييم فعالية نظام فولمر- فالنتين في زيادة عرض الحافة السنخية، و تحديد مقدار الامتصاص العظمي العمودي حول الزرعة السنية، و دراسة العلاقة بين عرض الحافة السنخية و كمية الامتصاص العظمي العمودي التالي حول الزرعة السنية.
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 technique, 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.

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 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 .
Our present study aimed at evaluating vertical resorption
following ramus and chin grafts applied in the split space after sixmonth
implant delay.

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 .
