Using conservative condylectomy for management of a large osteochondroma of the mandibular condyle with 6-year follow-up.

Osteochondroma is a hamartomatous proliferation of cartilaginous tissue, which is the most common benign tumor of the long bones, but is relatively rare in the maxillofacial region. Most cases of mandibular condylar osteochondroma manifest with facial asymmetry or malocclusion with limited temporomandibular joint movements. Several approaches for management of this lesion have been proposed, as conservative condylectomy technique. This procedure has been suggested a valid approach to minimize facial asymmetry, contributing to the recovery of occlusion associated with no local tumor recurrence, and without condylar reconstruction procedure. Therefore, this article aims to describe a clinical report of a true osteochondroma of the mandibular condyle in a 35-year-old patient who was successfully treated using conservative condylectomy procedure.

Arthrocentesis procedure: using this therapeutic maneuver for TMJ closed lock management.

Temporomandibular joint (TMJ) disorder is a term that encompasses a number of overlapping conditions, such as closed lock. Closed lock of the TMJ is considered a consequence of a nonreducing deformed disc acting as an obstacle to the sliding condylar head that usually causes a decrease in the maximum mouth opening and acute pain. The management of the TMJ is still controversial. Thus, arthrocentesis of the TMJ is a valuable modification of the traditional method of arthroscopic lavage, which consists of washing the joint in order to remove chemical inflammatory mediators and intra-articular adhesions, changing intra-articular pressure. TMJ disorder has always presented as a therapeutic challenge to maxillofacial surgeons. Therefore, this paper aimed to describe a clinical report of a closed lock of the left TMJ in a 19-year-old female subject who was successfully treated by arthrocentesis procedure.

Surface characterization, biomechanical, and histologic evaluation of alumina and bioactive resorbable blasting textured surfaces in titanium implant healing chambers: an experimental study in dogs.

PURPOSE: The present study was conducted to determine whether biomechanical and histologic parameters would differ between implant surfaces blasted with bioactive ceramic resorbable media (biologic blasting) and blasted with alumina and acid-etched. MATERIALS AND METHODS: Fourteen beagle dogs were used. Eight animals received two implants of each surface per limb, and each limb provided samples that remained in vivo for 3 and 6 weeks. The other six animals received two implants of each surface in one limb, which remained in vivo for 1 week. After euthanization, half of the implants were subjected to torque-to-interface fracture; the other half of the implants were processed for nondecalcified histology to calculate bone-to-implant contact (BIC) and bone area fraction occupancy (BAFO). Statistical analysis was performed with the Kruskal-Wallis test (95% level of significance). RESULTS: While no significant differences were observed for BIC and BAFO between surfaces at all three times in vivo and for torque levels at 1 and 3 weeks, a significantly higher torque was observed for the biologic blasting group after 6 weeks in vivo. Bone morphology was similar between groups at all times. CONCLUSION: A significant increase in early biomechanical fixation was observed for implants with the biologic blasting surface. However, no significant differences were observed for BIC and BAFO at any observation point.

Miíase na cavidade bucal em paciente geriátrico: relato de caso / Myiasis in the oral cavity in the geriatric patient: case report

Pacientes geriátricos que apresentam comprometimento sistêmico severo muitas vezes necessitam de cuidados especiais. A limitação da atividade motora pode estar relacionada com as diversas condições médicas que acometem esses pacientes. O acidente vascular cerebral pode causar sequelas graves como, por exemplo, o comprometimento da motricidade do indivíduo. Neste relato, apresentamos um caso clínico de um paciente geriátrico com importante comprometimento da atividade motora, decorrente de um acidente vascular cerebral, acometido por miíase oral, devido à falta de cuidados específicos.

Geriatric patients who have severe systemic involvement often require special care. The limitation of motor activity may be related to several medical conditions that affect thesepatients. Stroke can be cause serious sequelae, such as motor impairment of the individual. Here we report a case of a geriatric patient with a significant impairment of motor activity, resulting from a stroke, affected by oral myiasis due to lack of specific care.
