Abstract
The invention relates to an intra-oral dental radiology sensor. The sensor comprises an electronic image acquisition module and a molded casing made of a hard plastic which is locally provided with overmoldings made of a softer plastic having the consistency of smooth rubber, covering the hard plastic in areas located on the outside of the casing and corresponding to projecting angular portions of the hard plastic, and also in areas located inside the casing at places where the electronic module may bear. The soft plastic is preferably a copolymer of the SEBS (styrene/ethylene-butylene/styrene) type whereas the hard plastic is preferably a polyamide. The patient's comfort is improved and the module is better protected against shocks without increasing its size.
