Embodiment Construction

[0019] Below in conjunction with accompanying drawing, the present invention will be further described: gap δ is produced between stainless steel dental crown (1) and adjacent tooth (or stainless steel dental crown) (2), as figure 1 shown. Grind the grooves on the stainless steel crown (1) and the adjacent tooth (or stainless steel crown) (2) on both sides of the gap. According to the situation, the double-sided groove can be ground, and the single-sided groove can also be ground, such as figure 2 shown. Prepare a stainless steel T-shaped stainless steel insert (3) of suitable size for double-sided bevelling, or an L-shaped stainless steel insert (3) for single-sided bevelling, such as image 3 shown. The negative pole (5) of the welding power supply of the capacitor energy storage welding machine (4) is clamped on the stainless steel crown (1) with a large contact area, and the positive pole is connected to the welding pen (6). The pen tip is made of silver and silver all...

Abstract

The invention provides an oral cavity welding process for repairing stainless steel dental corona. When the gap between the stainless steel dental corona and the adjacent tooth (or dental corona), the repair is completed by the several steps of direct welding in the oral cavity by a condenser discharge pulse welding machine instead of replacing the dental corona, prefabricating a T-shaped or L-shaped stainless steel insert through grinding grooves at two sides or a single side of the gap between the teeth, multipoint welding and bite repair and grinding of upper and lower teeth. The method has high restoration quality of the gap between the teeth, good effect, low cost, safety and reliability and no pain of patients, and can completely solve the problem of stuffing the gap between the teeth by food.

Description

technical field [0001] The invention belongs to the field of oral hygiene, and in particular relates to an intraoral welding process for repairing stainless steel crowns. Background technique [0002] Dental hospitals often repair some damaged teeth with stainless steel crowns. After a period of use, the gap between the stainless steel crown and the adjacent tooth (or stainless steel crown) will gradually expand, causing food to be easily inserted into it. And the patient has to pick between teeth after each meal, which aggravates the destruction of teeth. The dental hospital's current repair method for this situation is: cutting and removing the original stainless steel crown, and reprocessing a new stainless steel crown. This method not only has high medical expenses, but also requires a long period of time due to the steps of removing the crown, making a dental model, making a stainless steel crown, and installing and running-in, which increases the pain of the patient....
