Suction tool

A method of reducing noise caused by suction through a dental suction tool, comprising:

• providing the dental suction tool comprising:
• an elongate body including a first material and a central passageway extending from a proximal connection end portion to a distal suction end portion, the elongate body defining a unitary body;
• and
• a tip portion extending over at least a portion of the elongate body and positioned at the suction end portion of the elongate body, the tip portion including:
• a second material different from the first material;
• and
• a pressure prevention recess positioned between an upper portion and a lower portion of the tip portion, the upper portion and the lower portion positioned on opposite sides of a longitudinal axis extending between the tip portion and the suction end portion, the upper portion comprising a distal-most upper outer edge facing a distal direction away from the elongate body, the lower portion comprising a distal-most lower outer edge facing the distal direction and perpendicular to the longitudinal axis, and the pressure prevention recess comprising a distal-most recessed outer edge facing the distal direction:
• wherein the distal-most recessed outer edge of the pressure prevention recess is positioned closer to the elongate body than the distal-most upper outer edge of each of the upper portion and the distal-most lower outer edge of the lower portion;
• wherein the distal-most outer edge of the lower portion is positioned closer the elongated body than the distal-most outer edge of the upper portion;
• and
• wherein at least the tip portion reduces noise caused by suction through the dental suction tool.

A method of manufacturing a suction tool, comprising:

• forming an elongate body defining a unitary body including:
• a first material;
• a longitudinal axis extending between a distal suction end portion and a proximal connection end portion that is configured to connect to the dental suction system;
• an inner surface defining a central passageway extending from the connection end portion to the suction end portion;
• and
• an outer surface;
• and
• a screen mechanism positioned within the central passageway, the screen mechanism including a plurality of openings that are configured to allow evacuated matter to pass through;
• and
• forming a tip portion extending over at least a portion of the elongate body and positioned at the suction end portion of the elongate body, the tip portion including:
• a second material different from the first material;
• an upper portion comprising a distal-most upper outer edge facing a distal direction away from the elongate body:
• a recessed portion comprising a distal-most recessed outer edge facing the distal direction:
• and
• a lower portion comprising a distal-most lower outer edge facing the distal direction and perpendicular to the longitudinal axis, the lower portion integrally formed with the upper portion and at least partially spaced apart from the upper portion by the recessed portion, the upper portion and the lower portion positioned on opposite sides of the longitudinal axis:
• wherein the recessed portion connects the upper portion and the lower portion;
• and wherein the distal-most recessed outer edge is positioned closer to the elongate body than the distal-most upper outer edge of the upper portion and the distal-most lower outer edge of the lower portion, wherein the distal-most outer edge of the lower portion is positioned closer to the elongated body than the distal-most outer edge of the upper portion.
