هل الكثافة العظمية الشعاعية أكبر عند الزرعة أم السن؟ و هل تتغير الكثافة بعد سنة من التحميل بين السن و الزرعة المرتبطة بجسر؟ هدف البحث إلى دراسة تغير قيم الكثافة العظمية الشعاعية خلال سنة من المراقبة الشعاعية للمنطقة العظمية حول الدعامة السنية و الزرعة المرتبطة بجسر من ثلاث وحدات بشكل (صلب أو غير صلب) اعتماداً على الصور الشعاعية الذروية الرقمية.
Isthe radiographic bone density bigger at the area of implant orof tooth?and is thisdensity changingafter one year of function betweentooth and implant connected with bridge? the aim of the studyis tostudythe changing of radiographic bone density during one year of radial observation of the bone area around the tooth and implant connected with bridge with 3 units(rigid or non-rigid connection) depending on digital periapical radiographic.

Is the changing of biomechanics between the tooth and implant affected on the
homogeneity of bone surrounding the tooth and implant connected with fixed prosthesis. the aim of the
study is to study the connection of bone area in both sides (mesial&distal) of tooth & implant connected
with bridge(in the form of rigid or non-rigid connection) during one year of radial observation of
radiographic bone density.
Background& Objective: The reduction of alveolar crestal bone density is one of the earlier signs of periimplant
disease and precedes the loss of height of the alveolar crest, because of that early detection of the
small changes in density is impor
tant and lead to the early onset of treatment and increases its success's
percentage.
This study aimed to evaluate the ability of the direct conventional digital method in detection of density
changes around dental implants by the mean value of the gray level of the histogram of the selected area
comparing with radiographic subtraction method.
Soft laser applications continue to improve local bone mineral density which is considered the most important factor in dental implant success.
This study aims to evaluate the Trabecular to Cortical bone ratio (TCr) index -as a simple easy measureme
nt index- that expresses the bone mineral density. This is to be able to predict the success of dental implants.
The study included 40 patients, who had a single implant in the lower molar region. The patients are divided into two groups: 20 patients had an implant with a soft laser application, i.e. GaAlAs laser (wavelength 830 nm), and 20 patients had an implant without a soft laser application.
Ordinary Analog periapical radiographs were used with calibration Stepwedge of pure aluminum, a medical Dijora program was used to measure radiographically local bone density in the periapical radiographs, and a panoramic Tomography was made to study TCr and two bone density indices (thickness ratio x density ratio) and (equivalent Aluminium thickness). All were measured during the period before implantation and 3, 6, and 9 months after the implantation.
The study found a strong linear correlation between the TCr and (thickness ratio x density ratio) 0.001>P, R2= 0.842 36(r = 0.8. and equivalent Aluminium thickness(
0.001> P, R2 = 0.656735, (r = 0.8).
The study shows that TCr index expresses both radiographic indices which reflect the local bone density, which means that the TCr is associated with such density. Therefore, it can be used as an easy way to predict the quality of bone, and prognosticate the success of dental implants.
To report the results of evaluation of the color digital subtraction technique in
assessing quality and quantity peri-implant bone changes in dental x-ray imaging.
Aim of the Study: To evaluate the changes to the radiographic
bone density of the mental bone grafts applied in terms of ring
technique until 18 months post operatively and to evaluate the
effect of the adjacency of neighboring teeth.
