ObjectivesThe role of alloplastic materials in maxillofacial reconstruction is still controversial. Determining the utility of porous, high-density, polyethylene implants as a highly stable and flexible, porous alloplast, with properties such as rapid vascularization and tissue ingrowth, is crucial in cases of maxillofacial deformities and aesthetic surgery.Materials and MethodsThirty high-density porous polyethylene implants were implanted in 16 patients that had been referred to a private office over a three-year period. These implants were used for correcting congenital deformities, posttraumatic defects and improving the aesthetic in nasal, paranasal, malar, chin, mandibular angle, body and orbital areas.ResultsThe outcomes of the cases in this study showed good aesthetic and functional results. The majority of patients had no signs of discomfort, rejection or exposure. Two implants suffered complications: a complicated malar implant was managed by antibiotic therapy, and an infected mandibular angle implant was removed despite antibiotic therapy.ConclusionBased on the results, the Medpor implant seems to be an excellent biomaterial for correcting various facial deformities. Advantages include its versatility and relatively ideal pore size that allows for excellent soft tissue ingrowth and coverage. It is strong, flexible and easy to shape.

Objectives. This study aimed to assess the radiographic position of impacted mandibular third molars (IMTMs) and their association with pathological conditions. Materials and Methods. The impaction depth, relationship with ramus, and angulation of 1600 IMTMs and their association with 2nd molar distal caries and root resorption, pathological conditions, and proximity to the mandibular canal were evaluated on panoramic radiographs. The IMTM position was determined based on the depth of impaction according to the Pell and Gregory classification, relationship with ramus according to the Pell and Gregory classification, and angulation according to the Winter’s classification. The classical and Bayesian logistic regressions were applied to analyze the effect of IMTM position on the associated complications using the odds ratio (OR) and 95% confidence interval (credible interval for Bayesian models). Two-tailed P value < 0.05 was considered statistically significant. Results. Of 1600 IMTMs evaluated in this study, 195 (12.2%), 252 (15.8%), and 119 (7.4%) had caused second molar distal caries, second molar root resorption, and pathological lesions, respectively, and 872 (54.5%) had contact with the mandibular canal. Impaction angulation was a risk factor for second molar distal caries (maximum OR = 5.01, 95% CI: 3.12–8.18). Changed angulation and greater impaction depth were the risk factors for second molar root resorption (minimum OR = 1.64, 95% CI: 0.58–4.02). Decreased distance between the ramus and distal side of the second molar was a risk factor for associated pathological lesions (minimum OR = 2.73, 95% CI: 1.79–4.25). Mesioangular and horizontal angulations and greater impaction depth were the risk factors for contact with the mandibular canal (maximum OR = 3.44, 95% CI: 2.6–4.57 and minimum OR = 1.3, 95% CI: 094–1.8). Conclusions. The frequency of complications associated with IMTMs was low, but considerable. The occurrence of these conditions might be affected by the impaction position. Thus, regular follow-ups are recommended in order to be able to surgically intervene when the first signs of pathologies arise.

Objectives: The use of fat grafts in maxillofacial sculpturing is currently a common technique. Unlike fillers, autologous fats unite with facial tissues, but long-term results may still be unsatisfactory. Sharing long-term follow-ups can be helpful in making outcomes more predictable. Materials and Methods: The data from patients who were admitted from 2014 to 2016 for fat augmentation were collected. In all cases, fat grafts were injected by blunt cannula using a tunneling technique in different planes. A fan shape order for the malar, periorbital, nasolabial fold, mandibular angle and body, and perioral area was established. Results: Autologous fat was used for different sites of the maxillofacial regions. Of 15 patients, two patients were not satisfied due to fat graft resorption. For this, further injections were performed six months after the first injection using preserved fat grafts. One patient continued to be dissatisfied. There were no other complications related to fat transplants. Conclusion: Fat transplantation is a safe, reliable, and non-invasive method for facial contour and facial soft tissue defect restoration. Additional methods such as mesenchymal stem cells along with fat injection increase the survival rate of transferred fat.

Objective: Evaluation of the quality of education and the relevant curriculum is one of the most important steps for optimizing the educational process. One of the ways to address the quality control is to continuously assess the postgraduate students’ opinions. This study aimed to evaluate satisfaction of senior postgraduate students of oral and maxillofacial surgery with the specialty curriculum. Materials and Methods: The target population in the present cross-sectional study consisted of all the senior postgraduate students in the field of oral and maxillofacial surgery all over Iran during the 2016−2017 educational year. The research questions consisted of 3 questions on demographic variables and 23 on educational variables, the characteristics of clinical education (including physical conditions and the number and varieties of the patients), the possibility of access to academic sources, the independent activity of post graduate students in taking history, the quality of educational activity of the professors, the quality of hospital wards and their interest in their field of study. Results: The mean age of the post graduate students was 32.4Å}3.8 and 93.5% % were male. Among the post graduate students, 58.1% were fully satisfied and 41.9% were moderately satisfied with the curriculum. A total of 64.5% of the post graduate students were fully satisfied with theoretical lessons, while 32.3% and 3.2% exhibiting moderate and low satisfaction rates, respectively. For practical training, 61.3% of the post graduate students were fully satisfied and 38.7% exhibited a moderate level of satisfaction. In clinical training, 7.38% of the post graduate students reported full satisfaction, while 58.1% and 3.2% reporting moderate and low rates of satisfaction, respectively. A total of 58.1% of the post graduate students were moderately satisfied with the facilities available and 41.9% reported a low satisfaction rate. Satisfaction was the same among females and males. Conclusion: Since the educational curricula and the educational facilities have been designed for high-quality education of the post graduate students, it is necessary to take the necessary steps to revise the curricula and improve the educational facilities.
