El logro en la reduccion del tiempo de osteointegracion del implante podria favorecer la carga inmediata o temprana de los implantes. El objetivo del estudio fue evaluar la osteointegracion inducida por L-PRF y la relacion hueso-implante (BIC) en un modelo animal experimental. Material y Metodos: Se utilizaron doce conejos blancos de 4 meses de edad, de Nueva Zelanda. Despues de la anestesia general, se obtuvieron de la arteria central de la oreja del conejo 3-5 ml de sangre y se preparo L-PRF. Fueron creadas dos cavidades de implantes (5 mm de largo y 3 mm de diametro) en cada tibia, un total de cuatro cavidades de cada animal. Dos de estas cavidades se seleccionaron y se cubrieron con PRF (Grupo de prueba). El resto de L-PRF se utilizo para impregnar los implantes colocados en l...

Relaxin is able to induce the multistep differentiation process of human osteoclastogenesis and exhibits anti-fibrotic and anti-inflammatory actions, and promotes vasodilatation, wound healing, and angiogenesis. The present study aimed to evaluate the effect of relaxin hormone on prevention and management of BRONJ. Materials and Methods:Thirty six male Sprague-Dawley rats were used in this study. The rats were randomly divided into four groups. In the first group Relaxin and Bisphosphonate were applied together in the same time for 12 weeks, in the second group Relaxin was applied for 12 weeks following Bisphosphonate, in the third group only bisphosphonate was alone and the fourth group saline (control) alone were applied to four groups of rats.Results:Necrosis, inflammation and the intensity of the osteoblast cells in the mandibles and BRONJ wer...

Thirty-seven skeletal class III patients were included in this study. The Mallampati score, body mass index (BMI), maximal inter-incisal distance, and thyromental and sternomental distances of these patients were evaluated preoperatively and at 6 months and 2 years postoperatively. A sagittal split ramus osteotomy (SSRO) without genioplasty was performed in all patients by the same surgical team, and anaesthesia was provided by the same anaesthesiologist using nasotracheal intubation. The paired samples t-test and Wilcoxon signed-rank test were used for statistical comparisons of the data. There were no statistically significant changes in BMI or sternomental and thyromental distances after SSRO. The maximal inter-incisal distance was significantly reduced at 6 months postoperatively (P<0.05), but no statistical difference was found between the values obtained preoperatively and at 2 years postoperative. A statistically significant increase in Mallampati score was observed postoperatively (P<0.05). Both the patient and practitioner should be aware of the risks associated with an increased postoperative Mallampati score in mandibular setback patients. The amount of mandibular setback in skeletal class III patients with a high preoperative Mallampati score should be limited to prevent potential postoperative airway problems.

The aim of this study was to evaluate submental-cervical soft tissue contour changes following mandibular advancement and set-back procedures via bilateral sagittal split ramus osteotomy. Sixty-seven patients were included in this study. Group 1 consisted of 27 skeletal Class II patients who underwent mandibular advancement surgery, whereas Group 2 consisted of 40 skeletal Class III patients who underwent mandibular set-back surgery. Various linear and angular measurements were performed on pre-operative and sixth month post-operative cephalometric radiographs. A new method was used to evaluate the amount of sagging at submental region. The submental length did not change in Group 1; however, it decreased significantly in Group 2 (P < 0·05). The angle between submental plane and facial plane decreased to 95·9° from 98·8° in Group 1(P < 0·05), whereas it ...

The digital panoramic radiographs of 4106 dental patients (2428 female, 1678 male) were evaluated. Radiographs of patients 40 years of age or older were randomly chosen from a computer database. CAA findings were defined as radiopaque masses adjacent to the cervical vertebrae at or below the intervertebral space between C3 and C4 on the panoramic radiograph. The patients who had CAA findings were contacted by telephone, and some of them agreed to further evaluation. Evaluation included carotid ultrasound, ECG, echocardiography and treadmill exercise testing at the Department of Cardiology. Of 4106 patients, 88 patients (2.1%; 70 female, 18 male) had one or more radiopaque mass detected on digital images. All 88 patients with CAA findings were contacted by telephone and 23 agreed to further evaluation at the university hospital. Of these 23 patients, 8 (34.7%) had CAAs on carotid ultrasound and 15 (65.3%) had normal carotid arteries. From these eight patients with CAAs on Doppler ultrasound, 7 (30.4%) had plaques that were not haemodynamically significant and only one (4.3%) had significant plaque. The patient with severe carotid artery stenosis consequently underwent endarterectomy operation. There were no statistically significant differences between male and female in CAAs (P&gt;0.05). Digital panoramic images may have some diagnostic value for detecting CAAs and this early diagnosis could potentially increase the length and quality of life for people with CAAs.

Exactly 112 of the (15%) implants had dehiscence defects and 23 of them (3 %) had fenestration defects. A bone sheet was obtained from the nearest available cortical bone for covering a bone defect around an implant by using a new no: 15 scalpel. Survival rates of implants were evaluated.Results:One hundred and thirty-five exposed implant surfaces were augmented with autogenous bone, harvested by scalpel technique. The survival rate of these implants was 100% with no significant clinical finding.Conclusion:The scalpel technique described in the present study is easy, effective and reliable for the management of dehiscence or fenestration defects of dental implant...
