The limitation of residual bone height (RBH) and vital structures such as sinuses in the maxillary often make the implant placement procedure becomes complicated. Clinicians may perform sinus elevation prior to implant placement to accommodate the length of the implant fixture. Sinus elevation is an invasive procedure and complication may occur during the surgery including the most frequent complication is perforation of Schneiderian membrane. Objectives: To discuss a comprehensive management of implant placement and its complication step by step from surgical procedures to crown placement Case Report: 67-year-old female patient with partial edentulism in the right maxillary region, presence of sinus septum, and RBH was 4mm. The patient was planned to do sinus elevation surgery prior to implant placement, perforation of the Schneiderian membrane occurred while surgery performed and pericardium membrane was attached around the perforation site. Sinus re-entry and implant placement were performed after 3 months followed by prosthetics procedures in the next 6 month. Conclusion: Dental implant is a complicated treatment and complication may occur during the placement, thus a comprehensive management is very essential to minimize the risk of complications.

<p class="abstract">Subcutaneous fungal infections are caused by penetration of the causative fungi into the subcutaneous layer and usually present as single, localised non-tender nodular swelling. The diagnostic process is a vital dynamic process that requires effective communication and efficient collaboration. Aspergillus hyphae invade host tissues through release of various toxins like proteases, phospholipases, hemolysins, gliotoxin, aflatoxin, phthioic acid and other toxins. Under general anesthesia and proper aseptic conditions using Moure incision surgical debulking of the pre-maxillary mass was done and post-operatively oral antifungal medication was started. Multiple cystic swelling was sent for histopathological examination and found to be non-invasive Aspergillus fungal infection. Subcutaneous form of aspergillosis manifest as subcutaneous fungal infection. We presented an unusual case report of 45 years old immunocompetent female with cystic presentation of aspergillosis involving premaxillary region.</p>

Purpose. To present an extremely rare case of localized amyloidosis of the mucosa of the maxillary alveolar ridge. Case Report. A 71-year-old man was referred to the Department of Oral Surgery, School of Dental Medicine, University of Zagreb, for a persistent nodular formation in the edentulous ridge of the anterior maxillary region. The nodular formation had a reddish color, solid consistency, and an approximate size of 40 × 15   mm . Orthopantomographic imaging excluded bone resorption and defects. Histopathological assessments of the biopsy specimen showed that the stroma was occupied by a multiplied, partially hyalinized connective tissue. The samples were subsequently stained with Congo red, and collagen accumulation under polarized light showed an apple-green birefringence indicating amyloid. Subsequently, the nodular formation was completely excised and a maxillary total denture was made. The patient showed normal tissue healing with no sign of recurrence at a follow-up assessment 1.5 years after the procedure. Conclusion. This is only the third reported case of localized amyloidosis of the alveolar ridge mucosa. Histopathological analysis is the first step for diagnosis, but systemic tests, blood counts, urinalysis, bone marrow biopsy, electrocardiography, and digestive endoscopy are recommended to rule out a systemic disease.

AbstractAlteration in conventional techniques in anterior maxilla is essential for making a restoration look more natural and harmonious with the rest of the mouth, as this area is more prone to aesthetic failure. The visibility of anterior crowns is obviously more, making it necessary for a restoration to blend with the natural dentition. This makes a person’s smile more pleasant and aesthetic. Proper risk assessment must be considered while placing implants in anterior maxillary region as any deficiency in bone and soft tissue could compromise the aesthetics as well as overall success of a dental implant restoration. Timing of implant placement also plays a crucial role in providing aesthetic success in this region. This article presents a case where implant placement is done, enhancing the aesthetics as well as function in the anterior maxillary region.

В данной статье описывается изучение распространенности зубочелюстных аномалий, в том числе и дистального прикуса среди детей и подростков школьного возраста. В настоящее время широко распространены зубочелюстные аномалии, в том числе дистальный прикус среди детей и подростков. Зубочелюстные аномалии приводят к функциональной патологии морфологических нарушений челюстной области. Изменения возрастно увеличиваются и сопровождаются деформацией лицевой области черепа наряду с эстетическими отклонениями.У больных часто наблюдаются нарушения положения позвоночника,функциональные изменения в системе малого кровообращения и задержка психосомтического развития.Это говорит о ранних нарушениях профилактики и несвоевременном оказании ортодонтической,зубопротезной и комплексной медицинской помощи.В связи с этим важную роль играет эпидемиологическая ситуация по зубной аномалии. исполняют информацию. Диагноз дистальной окклюзии называется боковым сегментом верхнего зубного ряда, расположенным перед боковым сегментом нижнего зубного ряда и появлением между ними дистальной стадии. Лечение и прогноз дистальной окклюзии зубного ряда зависит от возраста больного и характера аномалии [1] The article is devoted to the study of the prevalence of dentition anomalies, including distal occlusion among children and adolescents of school age. Currently, dental anomalies, including distal bite, are widespread among children and adolescents. Dental anomalies lead to functional pathology of morphological disorders of the maxillary region. The changes increase with age and are accompanied by deformation of the facial region of the skull along with aesthetic deviations. Patients often have disorders of the spine position, functional changes in the small blood circulation system and delayed psychosomal development.It tells about the early breaches of the prevention of and untimely provision of orthodontic, prosthodontic and comprehensive medical care.In this regard, an important role is played by the epidemiological situation of dental anomalies. execute information. The diagnosis of distal occlusion is called the lateral segment of the upper dentition, located in front of the lateral segment of the lower dentition and the appearance of the distal stage between them. Treatment and prognosis of distal occlusion of the dentition depends on the patient's age and the nature of the anomalies [1].

Objectives. The objective of our study was to evaluate the bone-implant interface in 10 cases of failure of fixed implant-prosthetic treatment by electron microscopy and spectrophotometry, in correlation with the evolution of Renouard-Rangert biomechanical scoring. Material and method. The study material was represented by 10 dental implants of 3 different morphological types (A, B, C), from the Biomat © collection, Polytechnic University of Bucharest, which were examined under the Phenom ProX electron microscope. The studied samples had a file in which there was noted the biomechanical score Renouard-Rangert from the treatment planning phase, but also from the patient dispensary phase. The survival time of the analyzed samples at the level of the maxillary bones was 7-24 months. Results. Following the examination at the electron microscope, the presence of an adherent neoformation bone tissue was detected on every implant, which covered each implant relatively uniform, with different degrees of mineralization depending on the type of implant, the duration of bone implantation and evolution of biomechanical scoring in red or yellow. Discussions. The use in our study only of standard size implants is an important advantage over other studies using mini-implants or temporary implants. The cases in which the biomechanical scoring reached "red" showed a lower degree of mineralization, and those that reached "yellow" had a higher degree of mineralization. Among the cases with biomechanical soring "in yellow" were samples collected from the posterior maxillary region, generally considered a risk area in implantology. Conclusions. In our study we found a correspondence between the modification of the Renouard-Rangert biomechanical scoring and the degree of mineralization of the bone deposited on the surface of the explants. Regardless of the evolution of biomechanical scoring, on all 10 analyzed samples we found a close contact between the neoformation tissue and the implanted devices, which indicates the high biocompatibility of the three types of implants. The relatively small number of samples analyzed is a limitation of our study. In the future, we recommend, in order to validate the results, to extend the study to a greater number of cases.

Mesiodens is the more frequent supernumerary tooth, located between the upper central incisors and can be found in deciduous or permanent dentition, with greater predominance for males, which can cause functional, aesthetic and psychological changes. Aiming to report a clinical case that presents two mesiodens bilaterally in the anterior maxillary region, causing impaction of the permanent upper central incisors. A non-syndromic, male, 5-year-old patient sought care accompanied by his legally responsible at the Pediatric Dentistry Clinic of the Universidade do Grande Rio, referred by the private clinic because it was believed that the procedure could only be performed with the use of conscious sedation. The treatment plan was carried out through imaging exams and clinical evaluation. It is concluded that a good evaluation, diagnosis, and adequate planning are fundamental in therapeutics. Therefore, they have allowed the eruption of the central incisors, contributing to a better quality of life and self-esteem.

The aim of this study was a comparative statistical analysis of three categories of maxillary odontogenic cysts, evaluating frequency in relation to localization (mandibular or maxillary region), age and gender of patients. The study was a retrospective cohort study conducted at the University Hospital of Messina. Three hundred and fifty-six maxillary odontogenic cysts were classified into 283 inflammatory, 43 developmental and 30 neoplastic cysts. Female patients are more affected by developmental odontogenic cysts, while male patients are more affected by inflammatory odontogenic cysts. Both the mandibular and maxillary regions were affected mainly by inflammatory odontogenic cysts; no significantly statistic relationship was found between lesions and age. A significant association between odontogenic cyst lesions and patient gender was found. No significant association between histological features of lesion and age of patient was observed, nor subtype of odontogenic disease and localization (mandibular or maxillary).

Introduction : A double tooth can be a consequence of fusion or gemination and is characterized by a size increasing of the tooth and a morphological modification. This anomaly concerns the anterior teeth and occurs in temporary and permanent dentition. Double teeth causes various problems (easthetic, occlusal, endodontic, orthodontic, periodontal…). The management of clinical situations involving such abnormalities is often complex. Our aim is to present reasoned analysis based on a systematic review of  therapeutic attitudes used in different clinical situations when the abnormal tooth is located at the anterior maxillary region. Material and methods : we carried out an electronic research via Pubmed and Sciencedirect to collect case reports published during the 20 recent years (1999-2020).  We included 46 articles corresponding to 57 relevant case report that we classified based on Aguilo and coll. Classification (1999). Results : Partial crown and root section is indicated for type I. Stipping is indicated for type II. The management of type III is compromised by the canal morphology .Extraoral and entraoral hemisection are only incated for type IV. Coronoplasty is usually unavoidable. Endodontic, orthodontic or periodontal treatment can be indicated depending on the situation. The extraction is considered as a last resort, the space is restored by autotransplantation of a supernumarary tooth, a prosthetic restauration or an implant by the end of the craniofacial growth. Conclusion : The managment of double teeth is a therapeutic challenge, every case is different, a multidisciplinary approach is recommended.
