Materials that can be used for the impression of implant restoration work do not include

Implanting working impression is an important step, which can provide accurate oral data and help dentists make dental restorations that meet the needs of patients. In planting and restoration work, commonly used materials include the following:

1. silica gel:

Silicon rubber is one of the most common impression materials. It has good elasticity and viscosity, and can provide high-precision oral impression. Silicone rubber is divided into silicone rubber and vulcanized silicone rubber. Polysiloxane rubber has high elasticity and is suitable for making fixed restorations. Vulcanized silicone rubber has a high viscosity and is suitable for making removable restorations.

2. Polyvinyl alcohol:

PVS is a high-precision impression material, which is very suitable for implant restoration. It has high viscosity and fluidity, and can provide excellent detail display and accuracy. PVS materials are divided into ordinary type and high viscosity type, which are selected and used according to actual needs.

3. Polysulfide (polyether)

Polysulfide is a durable and easy-to-handle impression material. It has high consistency and viscosity, and can provide excellent accuracy and detail display. The polysulfide material performs well in humid environment, so it can achieve good results even if the patient secretes a lot of saliva.

4. Impression mixture:

Impression wax is a traditional impression material, which is mainly composed of synthetic resin and wax. It has high plasticity and stability, and can effectively fix and transfer oral impression. However, due to the lack of elasticity, it may affect the accuracy of the impression, so it is less used in implant restoration.

In a word, the materials that can be used for working impression of implant prosthesis include silicone rubber, polyvinyl alcohol, polysulfide and impression wax. Each material has its own characteristics and scope of application, and dentists will choose the most suitable material according to the specific situation of patients. Professional dentists will be selected according to experience and clinical needs to ensure accurate oral impression and provide the best restoration effect for patients.
