A clinical case of a 42-year-old woman patient, who had a mandibular reconstruction utilizing a three-dimensional (3D) custom-made porous titanium plate dental restoration, is presented. She showed a recurrence of a unicystic ameloblastoma involving the left hemimandible. The patient declined to be managed by a bone-free flap. A mandibular resection in the healthy areas was provided, followed by reconstruction utilizing a 3D custom-made porous titanium plate dental restoration with a hybrid dental prosthesis. The 3D rehabilitation was created considering slim tomodensitometric sections. The cutting guides and custom-created 3D plate were fabricated employing medical software via computer-aided design and fabricating with locations planned for healing abutments. The patient was contented with the rehabilitation, and the condition continued stable at the four-year follow-up.

Osteoid osteoma is an osteoblastic benign bone tumor more frequent in long bones of young male patients. It is the third most commonly diagnosed benign bone tumor and has distinctive symptomatology, nocturnal pain that relieves with nonsteroidal anti-inflammatory drugs. Nowadays, total resection is the preferred management. In the present paper, an unusual variant in the maxilla of a female elderly patient without previous symptomatology is exposed; it was surgically removed without signs of reappearance in 12 months of follow-up. Although it is not a common site of appearance, the manifestation of this tumor in the skull bones seems to be associated with a different pattern in contrast to the skeletal type as can be seen in the present case and others previously reported. The authors consider due to the clinical similarity between this and other tumors that it should be taken into consideration for future diagnosis dilemma.

A clinical case of a 13 year old male patient with a malignant tumor in the mandibular body area with two years of evolution and associated pain is reported. It was initially diagnosed as low grade central mucoepidermoid carcinoma through Hematoxylin and Eosin (H-E) staining in multiple biopsies. Considering the clinical and radiographic characteristics of the lesion, it was necessary to confirm the diagnosis through Periodic acid-Schiff (PAS). The treatment involved hemimandibulectomy, neck emptying, and complementary radiotherapy. This article aims to present a rare occurrence of this type of intraosseous malignant tumor of glandular origin in a young patient. Key words:Mucoepidermoid carcinoma, periodic acid Schiff reaction, pathology, surgery, radiotherapy.

Antecedentes: actualmente existen diversas técnicas quirúrgicas con el injerto de tejido conectivo subpediculado que permiten lograr un cubrimiento radicular total o en alto porcentaje, contribuyendo de esta manera a la estética oral y a la toma de decisiones de los profesionales durante la práctica clínica. Objetivo: el objetivo de esta revisión sistemática fue comparar la efectividad de dos técnicas quirúrgicas en cuanto al nivel de cobertura radicular obtenido en los diferentes tipos de recesiones gingivales. Metodología: se seleccionaron las publicaciones más relevantes a través de una búsqueda en bases de datos electrónicas como Medline, Pubmed, Science Direct y Dentistry & Oral Sciences Source. Para ser incluidos en la revisión, los estudios debían definir la técnica quirúrgica usada y el nivel de cobertura radicular obtenido posteriormente. Resultados: se realizó la recopilación de 18 artículos que hablan acerca de la utilización de injerto de tejido conectivo subpediculado con o sin avance coronal, o solo realizando un avance coronal sin la utilización de un injerto como ayuda, alcanzando un alto nivel de cobertura radicular, mayor del 95% aun después de transcurrido 3, 6 o 9 meses después del tratamiento. Conclusiones: al evaluar la literatura sobre injerto de tejido conectivo subpediculado con o sin avance coronal, se evidenció una mayor ganancia de tejido a nivel de cobertura radicular para los procedimientos en los que se emplea la técnica de injerto de tejido conectivo subpediculado con avance coronal, frente aquel que no involucra avance coronal.
