BRUSH HEAD MANUFACTURING METHOD
A brush head (10) and a method for manufacturing a welded tuft assembly (20) for a brush head (10). The method includes inserting a bristle tuft (21) into an opening (51) in a retention element (52). A proximal end of the bristle tuft (23) and a proximal side (53) of the retention element are laser welded to at least partially melt the bristle tuft and at least a portion of the proximal side of the retention element together to create a merged proximal end head portion (26) that holds the welded tuft assembly together.

METHOD FOR MANUFACTURING A DENTAL BRUSHING PART, AND DENTAL BRUSHING PART
A method for manufacturing a brushing part, the brushing part being configured in a U-shape in order to be placed on the dentition of a jaw of a user, the brushing part forming a channel inside which is designed to receive all or a portion of said dentition, the brushing part comprising at least one tuft of brushing bristles projecting into the interior of said channel by a free end of the bristles of the at least one tuft, the method comprising the following steps: —forming the at least one tuft of bristles by assembling a plurality of bristles by an end opposite the free end, so as to form a base of the at least one tuft; —fusing the ends forming the base of the at least one tuft so as to form a fused area in one piece, such that an extension of the fused area in a direction that is transverse to an extension direction of the at least one tuft is greater at one extension of the base in the transverse direction prior to the fusing step; —placing the at least one tuft on a mold for overmolding the channel of the brushing part; —overmolding the channel and the at least one tuft.

BRUSH HEAD ARRANGEMENTS
A brush head (100) and a method of making a tuft spike (20) and a brush head with a plurality of tuft spikes. The brush head includes a matrix (30) having a plurality of receptacles (32) formed therein. A plurality of tuft spikes are each formed of a plurality of bristle strands (22) arranged in a tuft (21) having a free end (25) and a proximal end (23) inserted in a spike body (24). Each tuft spike is disposed in one of the receptacles of the matrix. A brush head neck (40) has a distal platen (42) that is connected to and at least partially encompassed in the matrix.
