Class II treatment of transverse maxillary deficiency with a single bone-borne appliance and hybrid clear aligner approach in an adult patient: A case report.

This case report describes the successful orthodontic treatment of a 22-year-old female patient affected by Class II malocclusion, maxillary skeletal transverse deficiency, ectopic maxillary left lateral incisor, and mild mandibular crowding. Due to her adult skeletal age, a bone-borne appliance was applied in order to obtain both purely skeletal rapid maxillary expansion and bilateral molar distalization. After accurate matching between the pretreatment cone-beam computed tomography scan and digital models, 4 self-drilling miniscrews were inserted palatally using a computer-aided design and computer-aided manufacturing (CAD/CAM) surgical template to guide their correct and safe placement, and a bone-borne appliance was fitted. After this first phase, the hybrid clear aligner approach was used to obtain alignment, levelling, and arch coordination, with the use of a partial lingual fixed appliance on the maxillary incisors.

Quality of life in fibromyalgia patients with craniomandibular disorders.

Fibromyalgia (FM) is a rheumatic disease which affects fibrous tissues and muscles; it is characterized by chronic pain and it is often associated with craniomandibular disorders (CMD). 31 patients were assessed from March 2012 to October 2012 through the administration of specific questionnaires and following neurologic and gnatologic assessment. A relevant corre-lation between FM and CMD emerges from the present study, as 80.6% of our patients report CMD symptoms with high prevalence of myofascial pain (84%). Multivariate regression analysis revealed that the patients in the present study did not differ in score of quality of life questionnaires from patients with fibromyalgia. The neuropathic pain diagnostic question-naire (DN4) scores were positively affected by belonging to group II of Research Diagnostic Criteria of Temporomandibular Disorders (RDC/ TDM) classification, suggesting the possibility of a neuropathic component in chronic pain in this CMD group, as already speculated in our study on the correlation between burning mouth syndrome and CMD and by other au-thors in studies on chronic low back pain. However, further clinic and instrumental studies are needed in order to test this as-sumption.
