•1. Develop a treatment plan and complete the pre-repair preparations
The doctor makes a thorough restoration treatment plan and selects the appropriate type of restoration according to the patient's dental defect etiology, defect size, position of the missing tooth, occlusion, remaining teeth in the mouth, eating habits, and patient requirements. Various preparations before restoration, including: endodontic, root canal treatment for apical diseases, periodontal treatment, orthodontic treatment before restoration, etc.
•2. Tooth preparation
The doctor prepares the tooth according to the type of restoration selected, the condition of the remaining tooth in the mouth, the position of the missing tooth, and the occlusion situation, etc., to provide restoration space for the production of the restoration.
•3. Making impressions and models
After the tooth preparation is completed, the doctor selects appropriate impression materials to make an impression and casts a plaster model. For the teeth with the edge design located under the gums, it is necessary to use a retraction cord or other methods to line the gums so that the impression material can enter between them to form a clear and accurate edge shape and ensure the shape and closeness of the restoration edge.
•4. Color comparison of restorations
(1) The physician perceives and differentiates the color information of the patient's remaining teeth.
(2) Recording the color characteristics of the teeth.
(3) Accurate transmission of tooth color information to the porcelain technician via technical process instructions or computer network image transmission.
•5. Technician fabricates the restoration
(1) Fabrication of metal base crowns
Mainly includes the following steps. 1) working model production: including working model trimming, nail insertion and other nearly ten processes; 2) wax model production: including wax model stacking, back cutting, finishing, sealing, making grip wax model, inserting gating and base; 3) wax model embedding, casting, ring opening, sandblasting, trial casting on working model; 4) polishing; 5) base crown and porcelain bonding surface treatment: fine polishing, sandblasting cleaning, oxidation. A total of nearly 30 processes.
(2) Porcelain layer production
Porcelain layer generally includes opaque porcelain, dentin porcelain, enamel porcelain three layers, need to use porcelain powder after repeated accumulation, sintering formation.
(3) Metal porcelain crowns are tried on the model, stained and enameled.
•6. Clinical trial wear and bonding of restorations
The metal porcelain crown is placed in the patient's mouth. The contact relationship between the crown and the adjacent teeth, the tightness of the edges to the teeth, the adjustment of the occlusal relationship, and sometimes the modification and adjustment of the shape and color of the full crown are required. After the above fitting steps are completed, polishing and glazing are performed, followed by bonding in the clinical setting.
