Abstract Background Correct positioning and alignment of dental implants are crucial to successfully meet the aesthetic and functional criteria in implant-prosthetic rehabilitation. When an implant is in the wrong position, especially in the esthetical zone, there are limited options to solve it. Some techniques have been described to reposition implants, such as reverse torque, trephine drills, and segmental osteotomies; current approaches aim to reduce the damage of the periimplant tissues. Case presentation A 20-year-old man with good general health was referred to the oral and maxillofacial surgery department of the CES University, Medellin Colombia in 2017, He had undergone a previous camouflage orthodontic therapy for a dental Class III, which finished in 2014, posteriorly a dental implant was placed in 2015 to replace upper right lateral incisor (1.2) before vertical growth of maxilla was complete; therefore, the implant was retained in a coronal position. A segmental osteotomy was suggested to reposition the implant in a more caudal position, a 3D surgical cut guide obtained by virtual planning was used to increase osteotomy accuracy and lower human error, to avoid the risk of damaging the adjacent tissues and to achieve a predictable result. Conclusions The segmental alveolar osteotomy is an effective alternative to reposition an implant; however, it must be carefully planned because human error remains a possibility that may affect the final result. Therefore, 3D planning is a better way to minimize these mistakes during the surgical procedure and the final position of the implant.

Dentin Formation

Introduction. Dentin dysplasia is a rare disturbance of dentin formation characterized by normal enamel but atypical dentin formation with abnormal pulpal morphology that is inherited as an autosomal pulpal morphology.Case Presentation. A 7-year-old female who had problems in chewing function was referred to Oral and Maxillofacial Surgery Department at the Faculty of Dentistry in Ondokuz Mayıs University. In the radiographic examination, it was determined that some of the unerupted permanent teeth of the patient had short, blunted, and malformed roots with obliterated pulp chambers, although the bone below the teeth showed well-defined margins. This unusual case of generalized short roots presents a case demonstrating both classic and atypical features of dentinal dysplasia type I (DDI) in the mixed and permanent dentitions.Conclusion. There are still many issues in the diagnosis and management of patients with dentin dysplasia. Early diagnosis, clinical and radiographic findings, as well as treatment of this condition and the initiation of effective preventive strategies may help prevent or delay loss of dentition.

Abstract Background Myopericytoma is a rare mesenchymal neoplasm with perivascular myoid differentiation that arises most commonly in middle adulthood. The lesion generally involves the subcutaneous tissue of distal extremities. Myopericytoma of the oral cavity is extremely rare. Herein we report a case of oral myopericytoma in a pediatric patient, who was treated via a conservative approach with a follow up of 8 years. The case is followed by a literature review. To our knowledge this is the first documented case of oral myopericytoma affecting a patient of such a young age. Case presentation A 6 years old boy was referred to the maxillofacial surgery department for the evaluation of a solitary growth of the right maxillary buccal and palatal gingiva. Histology and immunohistochemistry confirmed the diagnosis of myopericytoma. Conclusions Our patient was treated by local excision with no recurrence in 8 years of follow up. Conservative approach should be considered for the treatment oral myopericytoma especially in young patients in tooth bearing areas.

: Tooth impaction is defined as a partial or complete eruption of a tooth regarding the eruption time. Hereby, we present an infectious canine in a 38-year-old man that primarily presented with chest pain and dyspnea. After two days, he demonstrated a painful swelling and erythema of the face, severe perspiration, nasal congestion, and pleural effusion. The patient was diagnosed with acute bronchitis, mucormycosis, and nasal septum abscess, leading to unnecessary antibiotic therapy and lack of treatment response. After oral and maxillofacial surgery consultation, cone-beam computed tomography (CBCT) revealed an impacted and infectious canine that was surgically extracted. Due to lack of desired response to treatment, he underwent CBCT after oral and maxillofacial surgery consultation. An impacted and infectious canine was detected, which was surgically extracted. Three days later, his symptoms significantly improved, and he was discharged with a stable general condition.

Gingival pathology is a daily presentation, however a small number of systemic conditions can manifest similar to a common gingival condition and have fatal results. Dentist referred 56-year-old woman to Oral and Maxillofacial Surgery department with a 2-week medical history of gingival bleeding not responding to local measures. Biopsy showed eosinophilic infiltrate and vasculitis, and blood tests showed positive markers including cytoplasmic antineutrophil cytoplasmatic antibodies. Granulomatosis with polyangiitis is a rare disease affecting the respiratory tract, blood vessels and kidneys. Oral lesions are rarely the primary presenting feature. When left untreated, most cases are fatal within a year of diagnosis. The diagnosis can only be made when certain criteria are found, including granular oral lesions exhibiting an eosinophilic inflammatory infiltrate on biopsy. With 5% of cases showing intraoral lesions as the primary feature, it is essential that dentists have the knowledge of this rare disease to refer and not to treat as a common gingival condition.

Abstract Background: In the medical literature there are multiple reconstructive procedures for small and medium size defects of the lower lip, but only a few methods for larger defects involving the whole lower lip. Choosing the repairing procedure for larger lower lip defects must take into account two aspects: flap or flaps used should be local flaps, and suture lines should correspond to the natural facial creases or follow the functional lines of different facial aesthetic units. Finally, the flap or flaps should be large enough to restore the entire postexcisional defect. However, the more tissue is lost from the lower lip, the more challenging the reconstruction is from a functional and cosmetic point of view. Material and methods: During the last 2 years in the Oral and Maxillofacial Surgery Department of the County Emergency Clinical Hospital in Tîrgu Mureș, the unilateral Fujimori technique has been successfully used for the reconstruction of large lower lip defects in 4 patients with extended, neglected squamous cell carcinomas involving almost the whole lower lip tissue. These patients underwent complex surgical and oncological treatment. Surgery was performed in two stages: first, excision of the tumor and immediate lip reconstruction, and then removal of submandibular lymph nodes (level I), in the second stage. Results: The aesthetic and functional recovery of these patients was very good, with no need of other subsequent surgical corrections. Conclusions: The postoperative reconstruction of large defects of the lower lip is far from optimal, but it is very important to restore an adequate muscle function, the lip continence and a satisfactory facial appearance.

The rise of the COVID-19 pandemic has posed new challenges for health care institutions. Restrictions imposed by local governments worldwide have compromised the mobility of patients and decreased the number of physicians in hospitals. Additional requirements in terms of medical staff security further limited the physical contact of doctors with their patients, thereby questioning the traditional methods of clinical examination. Our institution has developed an organization model to translate the essential clinical services into virtual consultation rooms using a telemedicine interface which is commonly available to patients. We provide examples of clinical activity for a maxillofacial surgery department based on teleconsultation. Our experience is summarized and an organization model is drafted in which outpatient consultation offices are translated into virtual room environments. Clinical examples are provided, demonstrating how each subspecialty of oral and maxillofacial surgery can benefit from virtual examinations. The concept of “telesemeiology” is introduced and a checklist is presented to guide clinicians to perform teleconsultations. This paper is intended to provide an organization model based on telemedicine for maxillofacial surgeons and aims to represent an aid for colleagues who are facing the pandemic in areas where lockdown limits the possibility of a physical examination.
