Niceden Dental Internal and External Waterways Handpiece for Dentist Surgical Handpiece Low Speed Contra Angle

advantages： Dual waterway cooling: the inner spray waterway reaches the tip of the needle directly + the outer spray waterway covers the cutting surface.

Low speed and high torque: 1:1 direct drive (20,000-27,000 RPM) + ≥3.2N*cm output torque.

Ergonomic design: curved head optimizes the entry path of the rear teeth / straight head improves the stability of repair and grinding.

1.Curved head-deep fine operation Impacted tooth extraction: The angle is directly connected to the ascending branch of the lower jaw, and the minimally invasive tooth separation with a long-cracking drill is used to avoid flap trauma. Bone implant trimming: Direct injection of internal cooling water into the bone window to protect the integrity of the sinus mucosa when preparing the maxillary sinus to open the window Apical surgery: The fiber optic lighting version can illuminate the dark area of the apical tip and accurately remove the 3mm apical lesion. Treatment of subgingival caries: the elbow is directed to the gingival sulcus to protect the gingival papillary blood vessels when preparing for the hole.

2.Straight head-high stability operation Full crown edge grinding: 1:1 direct drive reduces vibration and prevents all-ceramic crown from chipping (especially zirconia restorations) Implant modeling: Take out the transfer body with a straight mobile phone drive to avoid scratches on the abutment. Large piece of resin polishing: 20,000 RPM constant speed to achieve mirror-level smoothness. Orthodontic belt ring removal: special turning needle dissolves the adhesive to protect the enamel from zero damage.
