[Provisional silicone obturator for closure of hard and soft palatal defects].

Treatment of intraoral squamous cell carcinomas is guided by the clinical stage of the disease and includes surgical resection. The resulting defect may be closed surgically or prosthodontically. This article describes a technique for provisional closure of a surgical defect. The interim obturator permits normal oral functioning until permanent rehabilitation is performed.

Development of a device for removing a partial denture in a patient with scleroderma.

Scleroderma is a chronic disease that has been associated with immune dysfunction. One of the oral manifestations is microsomia, a result of collagen deposition in the perioral issues. The complexity of treating these patients includes limited mouth opening ability, and difficulty inserting and removing dentures due to finger deformity. This article will describe an appliance specially designed especially for scleroderma patients, which facilitates treatment of the patient with removable partial dentures (RPD).

Technique for fabrication of splint preventing postsurgical restenosis in choanal atresia.

Choanal atresia, a congenital narrowing or obstruction of the nasal airway caused by significant respiratory distress in neonates, may require emergency intervention. Although atresia can be repaired surgically, restenosis is a common complication with this procedure. To prevent this, tubes are inserted into the nasal cavity immediately after surgery. This article describes a technique for preparing individual surgical splints designed to prevent postsurgical obstruction of the nasal cavity.

[The use of Dental D (polyacetal resin) as an alternative for chrome-cobalt removable partial denture: a case report].

Polyacetal resin (Delrin) is well known material in many medical fields as for artificial heart valves and artificial hip joints. In dentistry the material is known as Dental D, and among its other applications, is used for removable partial dentures. The article presents a cleft lip and palate patient with missing teeth (12 and 22). The patient underwent on operations for closure of the cleft, but even so some sinus tracts from the nasal cavity to the soft and hard palate exist. The patient was rehabilitated 10 years ago with chrome-cobalt removable partial denture, but lately, episodes of swelling and burning sensation were reported. The patient was diagnosed (by the allergy clinic in Hadassah hospital) as allergic to chrome-cobalt. Some optional treatment plans were offered to the patient (fixed, which involved an operation of closing the fistulas, and then a fixed restoration, another option was removable denture with Dental D). The patient chose to be rehabilitated with Dental D removable partial denture, which closes the fistulas and reconstructs the missing teeth. Due to the physical properties of the Dental D, its biocompatibility and the improved esthetics results, the Dental D can be a good alternative for the chrome-cobalt removable partial denture. The esthetic results with the Dental D, as far better than the conventional partial denture.
