A randomized double-blind clinical trial of the effect of amitriptyline on nocturnal masseteric motor activity (sleep bruxism).
Using a double-blind and randomized experimental design, ten adult subjects with sleep bruxism were administered amitriptyline (25 mg/night) and placebo (25 mg/night), each compound over a period of one week. Neither the intensities and locations of pains nor the nocturnal masseteric electromyographic activities were significantly affected by the tricyclic antidepressant. In fact, intake of amitriptyline was unpredictably associated with either an increase or a decrease in masseteric electromyographic activity (microV.s/min of sleep). On the basis of this study, small doses of amitriptyline cannot be recommended for the control of sleep bruxism and associated discomforts.

A multiple tray technique for implant-retained orbital prostheses.
The use of implants in retaining orbital prostheses has gained favor in recent years. Not all patients may be candidates for use of medical adhesives or anatomic retention as advocated by some. Osseointegrated implants offer an alternative method for retaining an orbital prosthesis. Because of the confining nature of an orbital defect, it may be difficult to reproduce the spatial arrangement of implants accurately with one impression. The technique presented here accomplishes the objectives of minimal trauma to the tissues, accuracy, and elimination of consecutive impression technique.

Implant reconstruction of a facial trauma patient: clinical report.
Dental implants can be used for the replacement of lost teeth as a result of trauma, even in complex cases with extensive loss of hard and soft tissues. Cooperation between the surgeon and restorative dentist is essential. The sequence of steps each team member must take to reach the definitive prosthesis stage must be clearly defined during treatment planning. A clinical report is presented.
