    UNASSIGNED: the present study aimed to establish an epidemiological profile of patients consulting the unit of maxillofacial prosthodontics in Rabat. Results deriving from this study will help enhance the quality of patient care in our center and can also serve as a comparison tool with other maxillofacial teams around the world.
    UNASSIGNED: during 11 months all patients consulting the unit of maxillofacial prosthodontics in our center were included. We opted for a questionnaire with 3 variables: socio-demographics, clinical examination data, and the type of prosthetic treatment adopted. The study was conducted in the Department of Removable Prosthodontics in the Center of Consultation and Dental Treatment of Rabat Morocco (CCDTR) from September 2020 to July 2021.
    UNASSIGNED: the study population consisted of 91 patients, with a majority of male patients at 53% (n=48). During our study period, the proportion of patients under one-year-old was predominant, accounting for 38.4% (n=35) of the total sample. Among the patients in the sample, 72.5% (n=66) had no profession, while 66% (n=60) had a low income. Regarding medical insurance, the majority of our patients, 85.5% (n=78), were covered by Public Health Insurance for the Low-income Population (PHILP). Among the total sample, 57.1% (n=52) consulted for a combination of pain function and aesthetics. Additionally, 61.5% (n=56) were referred by teaching hospitals. For the type of oro-facial defect, 52.7% (n=48) of the sample consisted of newborns with congenital facial cleft. Out of the 91 patients, 36 had maxillofacial tumors, with 47.6% (n=17) of them presenting squamous cell carcinoma. Furthermore, 63.7% (n=58) of the prosthetic treatments adopted involved presurgical orthopedic treatments for newborns with facial cleft.
    UNASSIGNED: the study on the epidemiological profile of patients attending the maxillofacial prosthodontics unit at Ibn Sina University Hospital in Rabat, Morocco provides important insights. The findings highlight the predominance of male patients and the prevalence of oro-facial defects in newborns. Socioeconomic factors, such as low income and lack of profession, are significant considerations. The majority of patients are covered by the PHILP, indicating the importance of medical insurance. These findings contribute to improving healthcare planning and specialized care for this patient population.

    It is a well-known saying that the eyes are \"windows to the soul.\" The absence or loss of any facial part, particularly the vision, can lead to severe physical as well as emotional trauma. Losing any part of the face causes the patient societal, physical, and psychological anguish. An ocular prosthesis aims to improve social acceptance and boost self-confidence by restoring the facial appearance. A pediatric dental specialist should be a part of the maxillofacial prosthesis team since maxillofacial prosthetic rehabilitation in young children can be challenging, especially with the less cooperative ones. The following case report describes these challenges in relation to a 5-year-old boy who had his eye enucleated due to trauma. The purpose of the case was to provide custom-built, acrylic ocular prostheses in as comfortable and atraumatic manner as possible by the maxillofacial prosthetic team.

    结果:在总共542个参考文献中,共入选33篇,包括25个上颌假体和8个下颌假体。数字工作流程的使用仅限于制造假体的一个或两个步骤,只有四项研究描述了完整的数字工作流程。最优选的数据采集方法是有或没有锥形束计算机断层扫描组合的口内扫描。
    结论:目前,颌面假体的制造过程需要结合数字和常规方法。简化数据采集方法并提供用户友好且负担得起的软件可以鼓励临床医生更频繁地对需要颌面假体的患者使用数字工作流程。
    OBJECTIVE: To evaluate the current evidence of digital workflow feasibility based on the data acquisition methods and the software tools used to fabricate intraoral prostheses for patients with partial or total maxillary and mandibular defects.
    METHODS: An electronic search was performed in PubMed, SCOPUS, and Web of Science using a combination of relevant keywords: digital workflow, digital designing, computer-assisted design-computer aided manufacturing, 3D printing, maxillectomy, and mandibulectomy. The Joanna Briggs Institute Critical Appraisal Tool was used to assess the quality of evidence in the studies reviewed.
    RESULTS: From a total of 542 references, 33 articles were selected, including 25 on maxillary prostheses and 8 on mandibular prostheses. The use of digital workflows was limited to one or two steps of the fabrication of the prostheses, and only four studies described a complete digital workflow. The most preferred method for data acquisition was intraoral scanning with or without a cone beam computed tomography combination.
    CONCLUSIONS: Currently, the fabrication process of maxillofacial prostheses requires combining digital and conventional methods. Simplifying the data acquisition methods and providing user-friendly and affordable software may encourage clinicians to use the digital workflow more frequently for patients requiring maxillofacial prostheses.

    In a rare condition known as vaginal agenesis, the uterus (womb) may develop only partially or not at all, while the vagina fails to develop altogether. It is common to diagnose vaginal agenesis, when a female does not start menstruation at puberty. This is a prenatal disorder that may also be linked to bone or kidney issues. Mullerian agenesis, Mullerian aplasia, and Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome are other names for the illness. Treatment modalities encompass surgical and nonsurgical interventions, including the utilization of prefabricated or customized vaginal stents for neovagina reconstruction and maintenance. This case report describes the development of a neovagina in a 27-year-old female diagnosed with vaginal agenesis, a characteristic of MRKH syndrome. A customized clear acrylic stent, designed to provide a resilient surface, serves as a straightforward and cost-efficient alternative for managing this condition. Significantly, it enhances patient\'s compliance and comfort during treatment, addressing both the physical and psychological ramifications of this congenital anomaly. This customized vaginal stent not only provides a practical solution but also contributes to enhancing the quality of life for individuals grappling with vaginal agenesis, thereby offering a promising avenue for addressing the multifaceted challenges associated with this condition.

    面部区域的任何器官的缺失导致不对称的外观。这种不对称的外观会给患者带来社会困境。颌面技师,修复医生,和病人必须紧密合作,以制造一个结论。在植入物上,首先建造了上层建筑。大部分是由环和连接植入物的杆组成。外饰的牢固的丙烯酸树脂基体配有夹子,用作外饰的保持机构。实际的附属物是由硅橡胶制成的。必须极其谨慎地塑造和着色。适当的替代品是保留植入物的耳廓假体。Microtia,畸形,畸形,和外耳的损失,部分或全部,可能是各种遗传遗传条件的结果。为了评估两只耳朵的对称性,使用人工智能(AI)软件。通过crystalwavesxx的Instagram镜头Gridset用于校正和验证患者的双侧对称性。此病例报告主要集中在使用AI制造植入物支持的耳廓假体。
    The absence of any organ of the facial region causes an asymmetrical appearance. This asymmetrical appearance can cause social dilemmas for the patient. The maxillofacial technician, the prosthodontist, and the patient must work closely together to fabricate an epithesis. On the implants, a superstructure is first constructed. Most of it is made up of rings and a bar that joins the implants. The firm acrylic resin base of the epithesis is equipped with clips that serve as the epithesis\'s retention mechanism. The actual epithesis is made of silicone rubber. The epithesis has to be shaped and colored with extreme caution. An appropriate substitute is an auricular prosthesis that is implant-retained. Microtia, deformity, malformation, and loss of the external ear, either partially or completely, can result from a variety of inherited genetic conditions. To evaluate the symmetry of both ears, artificial intelligence (AI) software is used. An Instagram lens Gridset by crystalwavesxx was used to correct and verify the bilateral symmetry of the patient. This case report primarily focuses on the fabrication of implant-supported auricular prostheses using AI.

    使用M511铂硅胶制作了总共240个样本,根据纳米颗粒的类型将其分为4组(n=60)(对照,聚四氟乙烯[PTFE],二氧化钛[TiO2],氧化锌[ZnO])添加,每组进一步分为3个亚组(n=20)进行颜色,撕裂强度(TS)和硬度(H)测试。进行了测试,并在6个月的户外风化前后获得了数据。
    在PTFE组中观察到风化后的最小颜色变化(ΔE=2.23)。在风化前,TiO2组显示最大TS(12.01N/mm),其次是PTFE组(10.85N/mm)。风化后,TiO2组(12.9N/mm)和PTFE组(12.54N/mm)显示最大TS。TiO2组风化前显示最大硬度(24.15肖氏A),PTFE组风化后显示最大硬度(33.43肖氏A)。
    在本研究的局限性内,可以得出结论,将聚四氟乙烯纳米颗粒添加到聚合物中可以增强光学和机械性能,并且可以被认为有利于延长假体的寿命。
    UNASSIGNED: The purpose of this comparative study in vitro was to evaluate the effect of organic and inorganic nanoparticles on colour stability, tear strength and hardness of maxillofacial silicone elastomer at baseline and when subjected to outdoor weathering for 6 months.
    UNASSIGNED: A total of 240 specimens were fabricated using M511 platinum silicone which were divided into total 4 groups (n = 60) based on the type of nanoparticles (control, polytetrafuoroethylene [PTFE], titanium dioxide [TiO2], zinc oxide [ZnO]) added and each group was further divided into 3 subgroups (n = 20) for colour, tear strength (TS) and hardness (H) testing. The tests were conducted and data was obtained both before and after outdoor weathering of 6 months.
    UNASSIGNED: Minimum colour change after weathering was observed in PTFE group (∆E = 2.23). TiO2 group showed maximum TS (12.01 N/mm) followed by PTFE group (10.85 N/mm) before weathering. After weathering, maximum TS was shown by TiO2 group (12.9 N/mm) and PTFE group (12.54 N/mm). TiO2 group showed maximum hardness (24.15 shore A) before weathering and PTFE group showed maximum hardness (33.43 shore A) after weathering.
    UNASSIGNED: Within the limitations of this study, it can be concluded that the addition of polytetrafuoroethylene nanoparticles to the polymer enhances both the optical as well as mechanical properties and can be considered favourable for the extended life of the prosthesis.

    背景:内植学,作为一种公认的治疗方法,越来越突出。植入治疗的决策过程和成功与患者的知识和期望密切相关。本研究旨在探讨年龄与口腔植入物知识之间的关系。
    方法:参与者分为三个年龄组(ag):ag1(35-44岁),ag2(65-74岁),和ag3(75岁及以上)。使用柏林居民登记处的数据,每个年龄组共随机选择400名参与者,德国。2016年至2017年进行了结构化电话访谈,采用了67项问卷,涵盖了意识,信息层面,成本估算,态度,和口腔植入物的经验。
    结果:尽管所有年龄组的总体知识水平都很低,年龄与口腔种植知识之间没有显著相关性。意识随着年龄的增长而增加。信息来源多种多样,和朋友们,熟人,和牙医扮演关键角色。参与者对植入物表达了不同的意见,耐久性和稳定性被确定为关键特征。年龄组之间在知识方面观察到显著差异,信息来源,以及牙医提供植入物的看法。
    结论:该研究表明需要有针对性的教育计划,强调适合年龄的信息来源,以提高口腔种植学的健康素养,尤其是老年人。对医生进行口腔种植基础知识的教育也至关重要。实施这些措施可以使个人能够就口腔种植治疗做出明智的决定,从而有助于改善口腔健康结果。
    BACKGROUND: Implantology, as a recognized therapeutic approach, is gaining prominence. The decision-making process and success of implant therapy are closely linked to patient knowledge and expectations. This study aims to explore the association between age and knowledge regarding oral implants.
    METHODS: Participants were categorized into three age groups (ag): ag 1 (35-44 years), ag 2 (65-74 years), and ag 3 (75 years and older). A total of 400 participants per age group were randomly selected using data from the residents\' registration office of Berlin, Germany. Structured telephone interviews were conducted between 2016 and 2017, employing a 67-item questionnaire covering awareness, information level, cost estimation, attitudes, and experiences with oral implants.
    RESULTS: Despite a low overall knowledge level across all age groups, there was no significant correlation between age and knowledge about oral implants. Awareness increased with age. Information sources varied, with friends, acquaintances, and dentists playing key roles. Participants expressed diverse opinions on implants, with durability and stability identified as crucial characteristics. Significant differences in knowledge were observed between age groups regarding awareness, information sources, and perceptions of dentists offering implants.
    CONCLUSIONS: The study suggests a need for targeted educational programs, emphasizing age-appropriate information sources to enhance health literacy in oral implantology, particularly among older individuals. Educating physicians on oral implant basics is also crucial. Implementing these measures could empower individuals to make informed decisions about oral implant treatment, thereby contributing to improved oral health outcomes.
