Method of manufacture of a dental prophy angle
A method of manufacturing a dental prophy angle with a wiper assembly is described. The prophy angle comprises a neck section and the neck section has an outer surface. The method comprises the steps of manufacturing a dental prophy angle, manufacturing a wiper assembly by molding a base, the base having an undersurface, the undersurface configured to match the outer surface of the neck section, molding a shield, the shield assembly comprising a carriage and a wiper, attaching the base to the shield assembly, and attaching the undersurface to the outer surface.
1. A method of manufacturing a dental prophy angle having a wiper assembly, the method comprising the steps of:
manufacturing the dental prophy angle, the dental prophy angle comprising a neck section, the neck section having an outer surface;
manufacturing a wiper assembly by:
molding a base, the base having an undersurface, the undersurface configured to match the outer surface of the neck section;
over-molding a shield assembly onto the base, the shield assembly comprising a carriage and a wiper;
attaching the undersurface to the outer surface.
2. The method of claim 1 , wherein the attaching step comprises at least one of gluing and ultrasonic welding.
3. The method of claim 1 , wherein the neck section comprises a first material and the base comprises a second material, the first material and the second material having a similar hardness.
4. The method of claim 3 , wherein the first material and the second material have a hardness of 60 to 90 Shore D.
5. The method of claim 3 , wherein the shield assembly comprises a third material, the third material being more flexible than the first material and the second material.
6. The method of claim 5 , wherein the third material has a hardness of 35 to 65 Shore A.
7. The method of claim 4 , wherein the shield assembly comprises a third material, the third material having a hardness of 35 to 65 Shore A.
8. A method of manufacturing a dental prophy angle having a wiper assembly, the method comprising the steps of:
manufacturing the dental prophy angle, the dental handpiece comprising a neck section, the neck section having an outer surface;
manufacturing a wiper assembly by:
molding a base, the base having an undersurface, the undersurface configured to match the outer surface of the neck section;
molding a shield assembly, the shield assembly comprising a carriage and a wiper;
attaching the base to the shield assembly; and
attaching the undersurface to the outer surface.
9. The method of claim 8 , wherein the attaching-the-undersurface step comprises at least one of gluing and ultrasonic welding.
10. The method of claim 8 , wherein the neck section comprises a first material and the base comprises a second material, the first material and the second material having a similar hardness.
11. The method of claim 10 , wherein the first material and the second material have a hardness of 60 to 90 Shore D.
12. The method of claim 10 , wherein the wiper comprises a third material, the third material being more flexible than the first material and the second material.
13. The method of claim 12 , wherein the third material has a hardness of 35 to 65 Shore A.
14. The method of claim 11 , wherein the wiper comprises a third material, the third material having a hardness of 35 to 65 Shore A.
