ينشط وضع الطعم عملية التجدد العظمي حيث قمنا في هذه الدراسة بعمل مقارنة بين استخدام التري كالسيوم فوسفات و استخدام العظم الذاتي كطعم عظمي للمساعدة في إعادة التشكل العظمي في حالات رفع الجيب الفكي.
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.

The objective of the present study was to investigate, in a sub-sinus
bone augmentation model in rabbits, effect of Three Calcium Phosphate
beta at different stages of the osteogenesis process. Histological and
statistical analyses were performed.
Rabbits underwent sinus augmentation procedures using Three Calcium
Phosphate beta (Cerasorb) and Collagen membrane ( Gen Derm ) .
Presence of maxillary septa has been known to be a complicating factor for sinus elevation procedure.
This study was aimed at detecting the prevalence, location and height of antral septa in syrianpopulation and to determine whether there is a relat
ionship between the presence of septa and the absence of upper molars .
A total of 174 sinuses in 87 patients (59 male and 28 female) aged 27 - 51 years were evaluated through a computed tomography scan analysis .
No correlation was observed between the presence of septa and the absence of upper molars.
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 floor of maxillary sinus starts to get down when the posterior upper teeth are extractedو which demand proceed sinus floor elevation when we plan to put dental implant in this place. The most common complication that happens in this procedure is
membrane perforation which took place at range of 5,5- 56.16 %. So the method of sinus lifting with balloon has spread which is considered a safe and affective method and it is indicated especially when there is a small dental loss (1-2 teeth ). The principle of this method depends on pumping a liquid ( saline usually ) into the balloon which causes sinus floor elevating slowly and continuously. The research aims to evaluate bone thickness when sinus floor elevated with balloon when there are adjacent teeth and when there are not. The balloon technique of sinus floor lifting is applied on 30 sinus lifting cases in 27 patients who have more than 2 teeth dental loss in posterior superior area and need sinus lifting for dental implantation in this area. The patients were divided into two groups: the first one included 15 cases of sinus floor lifting with balloon and there are approximate teeth to the edentulous area. The second group included 15 cases of sinus floor lifting with balloon when there are no adjacent teeth. Patients had been followed up in 5 periods using dental cone beam radiography ( after the surgery, after 3 months, after 6 months, after 9 months, after 1 year ). The research showed in the two groups that At confidence level of R = 95 % there were no statistic variations of the range of success, when there are adjacent teeth to the edentulous area and when there are not. The research recommends using balloon technique of sinus floor lifting when there are adjacent teeth and when there are not .
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 under
went lateral-approach sinus-lift
without bone grafts and implants were inserted simultaneously and
protruded 6 mm under the elevated sinus membrane.
