Maxillary sinus augmentation.

Attention to the principles of bone grafting, bone healing, and maxillary sinus physiology as well as anatomy is critical to the successful placement of dental implants in the posterior maxilla. The integration of these principles must take into account the restorative dental requirements and the patient's autonomy in guiding implant reconstruction. As in so many clinical disciplines, additional research is needed to provide better guidance for clinicians. Despite some gaps in our knowledge, however, sinus augmentation procedures have proven to be safe and effective and have permitted the placement of implants in sites that would have otherwise been impossible to treat. This article summarizes techniques and technologies related to maxillary sinus augmentation.

The impact of intravenous corticosteroids with third molar surgery in patients at high risk for delayed health-related quality of life and clinical recovery.

PURPOSE: To compare recovery for clinical and health-related quality of life (HRQOL) outcomes after third molar surgery in patients predicted to be at risk for delayed recovery, treated with or without intravenous (IV) corticosteroids at surgery. PATIENTS AND METHODS: Patients at least 18 years of age and with all 4 third molars below the occlusal plane were given IV corticosteroids just before third molar surgery. Clinical and HRQOL outcomes of these patients were compared with those of a nonconcurrent control group who did not receive corticosteroids. No antibiotics were administered. The control group was selected using the same criteria and treated under the same surgical protocol as the corticosteroid group. Differences between the groups were assessed with Cochran-Mantel-Haenszel row mean score statistics. RESULTS: Sixty patients were in each cohort. The incidence of delayed clinical recovery, a postsurgery visit with treatment, was higher in the control group compared with the corticosteroid group. In the corticosteroid group, 6 patients (10%) had 1 postsurgery visit with treatment. In the control group without corticosteroids, 17 patients (28%) had at least 1 postsurgery visit with treatment (P = .01). Compared with the control group, nausea tended to bother patients less on postsurgery day 1 (P = .07); sleep was improved on postsurgery days 1 through 4 (P < .05). Though not statistically significant, corticosteroids reduced the patients reported recovery by at least 1 day for pain, lifestyle, and oral function. CONCLUSION: Administration of IV corticosteroids before third molar surgery without antibiotics does not hamper clinical recovery even when healthy adult patients are predicted to have delayed recovery. Overall, IV corticosteroid administration had a limited, but beneficial effect on HRQOL outcomes.

Facial distortion secondary to idiopathic gingival hyperplasia: surgical management and oral reconstruction with endosseous implants.

Little information exists regarding the surgical and oral reconstructive options for the patient with idiopathic gingival hyperplasia, especially with regard to endosseous implant placement and recurrence of the disease. The authors report a case of severe gingival enlargement and bone resorption involving the maxillary and mandibular arches in a 21-year-old female causing distortion of facial features. The etiology could not be established but the condition was exacerbated during pregnancy, causing chewing, speaking, and esthetic problems. The hyperplastic tissue and all the teeth were removed surgically, followed by immediate placement of 2 endosseous implants. Restoration of esthetics and function with a maxillary denture and mandibular overdenture were completed 3 months later. No disease recurrence was noted at the 6-month postoperative interval.

Aspiration and ingestion in dental practice: a 10-year institutional review.

BACKGROUND: This article is an institutional retrospective review of incidents involving aspiration and ingestion of dental foreign objects at a large multidisciplinary dental educational facility. It was undertaken to determine which dental procedures were more likely to involve aspiration or ingestion, as well as to evaluate the outcome of these adverse incidents. METHODS: The inclusion criteria involved all patients who were documented to have experienced loss of dental instruments or material behind the posterior pharynx during a 10-year consecutive period. The dental and medical records of these patients were analyzed, and the outcomes of the adverse events fell into three categories: aspiration, ingestion, or neither aspirated nor ingested. The authors also noted the type of dental instrument and the specialty or area of dentistry in which this event occurred. RESULTS: There were 36 documented cases. Twenty-five of these were instances of ingestion and one was an aspiration. In 10 cases, aspiration and ingestion were ruled out through radiographic examination or the object was retrieved from the patient's mouth. CONCLUSIONS: Fixed prosthodontic therapy had the highest number of incidents of adverse outcomes. Ingestion was a more prevalent outcome than aspiration. Dental procedures involving single-tooth cast or prefabricated restorations involving cementation have a higher likelihood of aspiration. CLINICAL IMPLICATIONS: The implications for clinical practice include the recognition of risk that dental therapy demands in regard to the airway and posterior pharynx, documentation and follow-up of adverse outcomes, and the use of preventive measures such as rubber dams or gauze throat screens or floss ligatures.
