هدفت هذه الدراسة إلى دراسة تغيرات الارتفاع العظمي تحت الجيبي و نسبته المئوية التي يمكن تحقيقها عند رفع مخاطية الجيب الفكّي دون تطعيم لمسافةٍ قدرها 6 مم و ذلك اعتمادا على التصوير المقطعي المحوسب ذو الحزمة المخروطية CBCT. شملت العينة الكاملة للدراسة 18 غرسة لدى 11 مريض من الجنسين, حيث خضع جميع المرضى لرفع الجيب الفكي الخارجي دون تطعيم مع إدخال الغرسات السنية مباشر ةً أسفل المخاطية الجيبية المرفوعة بشكل حرٍّ و لمسافةٍ موحّدة قدرها 6 مم.
This study aimed to study changes in subantral bony height when sinus membrane was elevated 6 mm without bone grafts depending on Cone Beam CT imaging. The study sample contained 18 implants placed on 11 patients of both genders, each patient underwent lateral-approach sinus-lift without bone grafts and implants were inserted simultaneously and protruded 6 mm under the elevated sinus membrane.

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).
Graft insertion can effectively enhance the regeneration of
debilitated bone.
Aim: The effects of an alloplastic bone-replacing material, b-tricalcium
phosphate, and of autogenous bone graft were compared.
Sinus augmentation is a common approach for patients with
severe alveolar ridge atrophy.
Purpose of study: The objective was to compare the hydroxyapatite + PRP
with hydroxyapatite + Blood Clot in maxillary sinus grafts.
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 .
