يعتبر الحفاظ على العظم المحيط بالزرعة أحد أهم العوامل في نجاح هذه الزرعة وديمومتها وأن التغير في كمية ونوعية العظم المحيط بها لا يؤثر فقط على الاندماج العظمي لها وإنما يسبب بالإضافة لذلك تغير في شكل النسج الرخوة المغطية وبالتالي يؤثر على الناحية الجمالية والوظيفية للمعالجة.
Preserving the bone surrounding the implant is one of the most important factors in the success and durability of this implant, and the change in the quantity and quality of the surrounding bone not only affects the bone fusion of it, but also causes a change in the shape of the soft tissues covering and thus affects the aesthetic and functional aspect of the treatment.

Chin area is considered as a suitable donor site for autogenous bone grafts for
alveolar ridge reconstruction before dental implantation, using large trephine bur(10mm) considers one of
several ways which appeared for bone graft harvesting. The aim
of this search is to study radiographic
density changes following chin bone harvesting for dental implantology by using large trephine bur
depending on digital panoramic radiographs.
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.
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.
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.
In this study, 24 patients with posterior skeletal cross-bite were
treated at Orthodontics Department-Faculty of Dentistry in Hama
University. Hyrax expansion device was applied in all patients and
the results were assessed after active expansion
period. Cone
beam computed tomography radiograph were taken at the
assessment times.
Results showed that the midpalatal suture width has increased
significantly at all measured areas. The results revealed that
significant tipping in the canines , premolars and molars was
recorded in this study.
