Description
Technical Field
The invention relates to the technical field of dental restoration, in particular to an oral porcelain veneering accurate bonding guide plate.
Background
At present, the adhesion of the ceramic veneers is clinically completed manually, namely the ceramic veneers are tried on an intraoral abutment preparation body, the ceramic veneers are confirmed to be completely in place and have tightly sealed edges, after the ceramic veneers are well occluded, the ceramic veneers are pretreated by a pretreatment agent (an acid etching agent, a silane coupling agent and the like), a resin adhesive is coated on the tissue surfaces of the ceramic veneers, the ceramic veneers are manually reset on the abutment preparation body by a doctor again, redundant resin adhesive is removed after primary photocuring, and the resin adhesive is completely cured through complete photocuring, so that the ceramic veneers are adhered on the abutment preparation body.
Because the abutment prepared body with the porcelain veneer lacks obvious edge dead points, when the coating adhesive is repeatedly arranged on the abutment prepared body, the redundant adhesive can overflow from the edge to shield the edge, so that the observation of whether the abutment prepared body is completely arranged is very difficult; the finger pressing method adopted for keeping the porcelain facing surface from moving during primary photocuring is also unreliable, and the phenomenon that the porcelain facing surface moves is often found after the full photocuring is completed clinically, so that the whole repairing treatment fails.
For the adhesion of multiple ceramic veneers (such as maxillary left canine-right canine), clinically, the method is usually adopted that firstly, maxillary middle incisors on two sides are adhered at the same time, and then, two side incisors and canine teeth are adhered in sequence; five times of repeated operations are needed, wherein each operation comprises hydrofluoric acid etching (1.5 min), flushing (0.5 min), coating a silane coupling agent (1 min), blow-drying (0.5 min), polishing the tooth surface and acid etching (1.5 min), flushing (0.5 min), blow-drying (0.5 min), coating a primer, slightly blowing and illuminating (1 min), resetting the resin adhesive on the preparation body of the abutment after being coated on the porcelain veneering tissue surface, performing primary photocuring (1 min), removing the redundant adhesive (2 min), completely photocuring (1 min), adjusting the occlusion and polishing edge (3-5 min), and each operation needs 15-20 min. Because the porcelain veneers are small in size, thin in thickness and smooth in surface, the phenomena of slipping, damage and the like often occur when the porcelain veneers are clinically preprocessed and bonded by hands, time and labor are consumed, and the whole repairing treatment can also fail.
