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.

Research summary
تهدف الدراسة إلى تقييم تأثير تخانة النسيج المخاطي فوق قمة السنخ على الامتصاص العظمي حول عنق الغرسة السنية خلال سنة من المتابعة. شملت الدراسة 24 غرسة على 9 مرضى من الجنسين ممن لديهم فقدان أسنان خلفي سفلي. تم تقسيم العينة إلى مجموعتين: المجموعة الأولى (المخاطية أكثر من 2 مم) والمجموعة الثانية (المخاطية حتى 2 مم)، وتم وضع الغرسات في كل مجموعة على مستويين: عند مستوى قمة العظم السنخي وفوق مستوى قمة العظم السنخي بـ 2 مم. أظهرت النتائج زيادة في معدل الخسارة العظمية حول عنق الغرسة في المجموعة الثانية بفروق ذات دلالة إحصائية. خلصت الدراسة إلى أن تخانة المخاطية عند الغرس تؤثر على مقدار الخسارة العظمية حول عنق الغرسة، حيث يحدث امتصاص زائد إذا كانت المخاطية رقيقة (حتى 2 مم) وقت الغرس.
Critical review
دراسة نقدية: تقدم هذه الدراسة إسهاماً مهماً في فهم العلاقة بين تخانة المخاطية والامتصاص العظمي حول الغرسات السنية. ومع ذلك، يمكن أن تكون هناك بعض النقاط التي تحتاج إلى مزيد من التوضيح. أولاً، حجم العينة صغير نسبياً (24 غرسة على 9 مرضى)، مما قد يؤثر على تعميم النتائج. ثانياً، لم يتم توضيح ما إذا كان هناك اختلافات في نوعية العظم بين المرضى، وهو عامل قد يؤثر على النتائج. ثالثاً، الدراسة تركز على فترة متابعة لمدة سنة واحدة فقط، وقد يكون من المفيد متابعة المرضى لفترة أطول لمعرفة ما إذا كانت النتائج تستمر على المدى الطويل. على الرغم من هذه النقاط، فإن الدراسة تقدم معلومات قيمة يمكن أن تكون مفيدة في تحسين نتائج الغرسات السنية.
Questions related to the research
  1. ما هو الهدف الرئيسي من الدراسة؟

    الهدف الرئيسي من الدراسة هو تقييم تأثير تخانة النسيج المخاطي فوق قمة السنخ على الامتصاص العظمي حول عنق الغرسة السنية خلال سنة من المتابعة.

  2. كم عدد الغرسات التي تم استخدامها في الدراسة؟

    تم استخدام 24 غرسة في الدراسة.

  3. ما هي الفروق الرئيسية التي أظهرتها النتائج بين المجموعتين؟

    أظهرت النتائج زيادة في معدل الخسارة العظمية حول عنق الغرسة في المجموعة الثانية (المخاطية حتى 2 مم) بفروق ذات دلالة إحصائية.

  4. ما هي التوصيات التي خلصت إليها الدراسة؟

    توصي الدراسة برفع الغرسة فقط عندما تكون تخانة المخاطية عند قمة السنخ أكبر من 2 مم وقت الغرس، حيث أن رفع الغرسة في هذه الحالة يقلل من الامتصاص العظمي بشكل ملحوظ.

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 ( ID I-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 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.
the density of bone having an obvious effect on the osseointegration and the success of the dental implants. The aim of the present study is to evaluate the effect of different bone qualities on the values and distribution of stresses at the bone – impla
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.
