الهدف من هذا البحث تقييم تأثير قوة عزم الإدخال على نجاح الغرسات السنية المفردة الموضوعة في مكان القلع مباشرة وعلى حدثية الامتصاص العظمي حولها. المواد والطرائق: تلقى ثماني مرضى 24 غرسة سنية من التيتانيوم من نوع (IDI-BIO ) عُولج سطحها بالحمض وبالترميل, أُدخلت جميع الغرسات مباشرة بعد القلع . قُسِّمت العينة إلى مجموعتين: في المجموعة الأولى أدخلت الغرسات بقوة عزم إدخال أقل من 35 نيوتن سم (بمتوسط 25 Ncm ), في حين أُدخلت الغرسات في المجموعة الثانية بقوة عزم إدخال أعلى من 35 نيوتن سم (بمتوسط 52,2 Ncm). تمّ التقييم حصول الاندماج العظمي ومقدار الامتصاص العظمي الحفافي حول الغرسات في كلتا المجموعتين بعد شهرين وستة وتسعة أشهر من الغرس. النتائج : فشلت أربعة غرسات وجميعها من المجموعة الأولى في الاندماج العظمي, ولم يظهر التحليل الإحصائي وجود علاقة بين قوة عزم الإدخال والامتصاص العظمي حول الغرسات السنية الفورية المفردة
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 ( IDI-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 .

The aim of the study was to evaluate the influence of the mucosal tissue thickness on the crestal bone resorption around dental implants during a year of follow-up. Nine patients of both sexes included in this study received 24 implants. Patients in
the sample were divided into two groups: group I (mucosa above 2 mm, and 12 implants), and group II (mucosa up to 2 mm, and 12 implants). Implants in each group were divided into two groups: a control where 6 implants were placed at the crest level, and a test where (6) implants were placed 2mm supracrestally. The results revealed that there was an increase in crestal bone loss in group 2 with statistically significant differences. To conclude, the initial thickness of mucosa at the time of implant placement affects crestal bone loss; increased bon loss occurs when the tissue thickness is 2 mm or less at the time of implant placement.
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 .
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.
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
