Fixed rehabilitation of a patient with hypohidrotic ectodermal dysplasia using zygomatic implants

We found few references in the dental literature on implant rehabilitation of patients with hypohidrotic ectodermal dysplasia and only 1 case on zygomatic fixations and maxillary prosthesis in a patient with hypohidrotic ectodermal dysplasia. Two zygomatic fixations were placed according to the sinus slot technique, together with 3 implants in the anterior maxillary region. After 6 months, an upper complete prosthesis was screwed onto the implants, and lower overdentures were placed over the remnant canines. After 18 months of follow-up the patient reported important improvement in oral function and self-esteem.     

Restoration of irradiated patients using osseointegrated implants: Current perspectives

Statement of problem. The success rates of osseointegrated implants used to restore patients who were irradiated for head and neck tumors are influenced by radiation-induced changes in the hard and soft tissues.Purpose. This article examined, by review of the literature, current perspectives on the restoration of irradiated patients using osseointegrated implants.Results. In published reports that investigated both intraoral and extraoral applications, irradiation decreased implant success rates and the amount of reduction was dependent on the location within the craniofacial skeleton. The limited number of implants and patients in these studies precludes definitive conclusions regarding the efficacy of placing implants into irradiated tissues. The implants placed into the irradiated anterior mandible have demonstrated an acceptable implant success rate of 94% to 100% with a minimal risk of osteoradionecrosis. The efficacy of implants in the posterior mandible has not been examined. Implant success rates ranged from 69% to 95% in the irradiated maxilla for intraoral applications. Extraoral applications demonstrated excellent implant success rates in the temporal bone (91% to 100%). The rates in the anterior nasal floor have varied from 50% to 100%. The implant success rates in the frontal bone decreased as the length of the studies increased (96% to 33%). The long-term efficacy of implants in the irradiated frontal bone is poor.

False aneurysm of the facial artery

A case of an unusual traumatic aneurysm of the facial artery secondary to blunt trauma is reported. The lesion was typical in that it was pulsatile, had a systolic bruit, and had a filling defect that was evident on carotid angiography. Although a traumatic aneurysm is a rare occurrence in the facial region, the inclusion of this lesion in the differential diagnosis of soft tissue lesions is important if the serious consequences of hemorrhage are to be avoided.     

Surgical correction of mandibulofacial deformities secondary to large cervical cystic hygromas

The clinical features of cystic hygroma are presented. The effect on mandibular morphology is described, and surgical correction of the deformities is discussed.     

The Relationship Between Dental Utilization and Preventive Participation Among a Well-elderly Sample

Previous studies have shown that dental utilization by older people is lower than for the general population. This study hypothesizes that an elder's tendency toward participating in preventive health activities may be an important factor in explaining the likelihood of accessing the dentist. Subjects included 1,911 older individuals who enrolled in the UCLA Medicare Screening and Health Promotion Trial. All were interviewed about their utilization of preventive health services and participation in preventive behaviors. A recent dental visit was positively associated with all sociodemographic variables examined except age and sex. It was also related to health status questions and utilization of the preventive health services and health behaviors studied. Logistic regression analysis showed that both summary preventive health behavior and preventive service utilization variables were important factors in explaining a recent dental visit (model chi-square/221.4, P=.001) along with income, not having a removable prosthesis, and perceiving the need for dental care. This study showed that dental utilization is related to older people's participation in other preventive activities. When in contact with older people, health care professionals should consider current oral and general preventive health status and encourage appropriate referral for preventive activities.     

Adenomatoid odontogenic tumour of the jaws

The adenomatoid odontogenic tumour of the jaws is rare. It is important to differentiate it from other odontogenic tumours because of its benign behaviour and this can be reliably done by the histological features.     

Autogenous bone graft in conjunction with enamel matrix derivative in the treatment of deep periodontal intra-osseous defects: a report of 13 consecutively treated patients

AIM: The purpose of the present study was to investigate the effectiveness of a regenerative procedure based on supra-crestal soft tissue preservation in association with combined autogenous bone (AB) graft/enamel matrix derivative (EMD) application in the treatment of deep periodontal intra-osseous defects. METHODS: Thirteen consecutively treated patients, seven females and six males, aged 30-65 years, three smokers, were included. A total of 15 deep, one- to two-wall intra-osseous defects were selected. Immediately before surgery and 6 months after surgery, pocket probing depth (PPD), clinical attachment level (CAL), and gingival recession (REC) were recorded. RESULTS: PPD amounted to 9.4+/-1.8 mm before surgery, and decreased to 4.7+/-1.2 mm post-surgery (p<0.0000). CAL varied from 10.5+/-2.0 mm pre-surgery to 6.2+/-1.7 mm post-surgery (p<0.0000), with CAL gain averaging 4.3+/-1.4 mm. Fourteen (93.3%) defects presented CAL gain >/=3 mm. REC change was 0.4+/-0.7 mm. CONCLUSIONS: Results from the present study indicated that a regenerative procedure based on supra-crestal soft tissue preservation and combined AB/EMD treatment leads to a clinically and statistically significant improvement of soft tissue conditions of deep periodontal intra-osseous defects.
