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.

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
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
