Ectodermal dysplasia (ED) is a congenital syndrome characterized chiefly by abnormalities of tissues of ectodermal origin, namely skin, nails, hair, and teeth. Dental treatment of patients with ED is necessary because it affords the opportunity to develop normal forms of speech, chewing, swallowing, and normal facial support. Because there are few reports focusing on implants inserted in bone grafted in patients with ED, we therefore performed a retrospective study on 44 implants inserted in 4 patients to detect those variables acting on survival and crestal bone remodeling around implant neck in such subjects. Forty-four fixtures were analyzed. Several patient-related (age and sex), anatomic (maxilla and mandible and tooth site), implant (type, length, and diameter), surgical (sites and types of grafts), and prosthetic (type of loading) variables were investigated. Implant failure and peri-implant bone resorption were considered as predictors of clinical outcome. Kaplan-Meier algorithm and Cox regression were then performed to detect those variables statistically associated with the clinical outcome. Implant length and diameter ranged from 11.5 to 15 mm and from 3.5 to 4.0 mm, respectively. Implants were inserted to replace 12 incisors, 12 cuspids, 11 premolars, and 9 molars. No implant was lost. On the contrary, implant's length, grafted sites, and type of loading affected univariate analysis, but these data were not confirmed by multivariate algorithm. Dental implants and bone grafts to orally rehabilitate patients with ED are valuable devices with no difference if compared with unaffected patients, at least in adults.
Ectodermal dysplasia (ED) comprises a large heterogeneous group of inherited disorders that are characterized by primary defects in the skin, hair, nails, eccrine glands and teeth. The most characteristic findings are the reduced number of teeth. All rehabilitative programmes involve proper evaluation of skeletal relationships. Prosthetic-implantological treatment at the end of bony growth can be used. In this article a case of ED treated with Le Fort I for maxillary advancement, femur homografts, implants' insertion and immediate loading is described. In December 2007, a 38-year-old female was referred to the Maxillofacial Department of Galeazzi Hospital (Milan, Italy) who had a diagnosis of ED. Twelve implants were inserted in one-step surgical procedure. No implant was lost and all are stable. The occlusion is stable after 15 months of follow-up. The results indicate that the one-step oral rehabilitation can be performed in adults who are affected by ED. Also, this significantly reduces the time of oral and facial rehabilitation.
New applications of piezoelectric device have been already documented from otologic and ophthalmic endoscopic studies. The authors describe a first experience in endoscopic sinus surgery with piezosurgery to approach the paranasal sinus. Patients involved in this study presented for rhinogenous headache, rhinorrhea, nasal obstruction, and sinusitis. Radiological studies such as computed tomography of paranasal sinus and a correct clinical examination with a rigid endoscope 0 degrees were carried out, to exclude from the procedure patients with polyposis or other soft-tissue diseases. In fact, because of piezosurgery properties of micrometric and selected cutting on mineralized tissues, it has been used only to treat bone or cartilage anomalies of nasal sinus. The main advantages of the technique include soft-tissue protection and optimal visibility in the surgical field with decreased blood loss. From this preliminary report, the stability of mucous membrane previously cut has been documented by endoscopic follow-up, and the resolution of the main symptom of headache was referred. The main indications for piezosurgery shown in literature are in oral surgery, such as sinus lift, bone graft harvesting, osteogenic distraction, ridge expansion, endodontic surgery, and periodontal surgery. Other applications have been shown in otology, neurosurgery, ophthalmology, and orthopedics. Authors describe as a promising technique the piezoelectric device use in functional endoscopic paranasal sinus surgery in selected cases, with a minimal mucosal approach and thus the preservation of ventilation.
