简要总结
The study suggests that if the investigators used customized healing abutments synthesized from PEEK may have a favorable effect on peri-implant soft tissues regarding decreased plaque accumulation and healing stimulation compared to the customized conventional titanium healing abutments.
详细描述
Successful aesthetic implant therapy has several sequential goals such as prosthetically driven 3D implant placement. Implant placement must be done in the ideal position to support the restoration and the surrounding soft and hard tissues. The placement of a definitive restoration should also be in harmony with the adjacent natural teeth and surrounding soft tissue.
Guided implant surgery can provide precise, predictable, and safe implant placement. Computer-generated surgical guides vary in design according to the dental condition (edentulous or partially edentulous), type of support (tooth, mucosa, or bone), and the degree of limitation (non-limiting, partially-limiting, or completely limiting).
The use of healing abutments has the function which enables adequate healing of peri-implant soft tissue and promoting a good profile of peri-implant mucosa that allows an adequate emergence profile of the prostheses supported by the implant. They are available in different lengths and project through the soft tissue into the oral cavity.
Janakievski stated that prefabricated healing abutments are unable to support the supracrestal soft tissues because of their circular profile. Therefore, a custom healing abutment is preferred because it provides a replica of the definitive restoration of the patient's gingival architecture.
An evaluation of the use of customized healing abutments has been performed aiming to assess possible advantages associated with this treatment modality. This procedure allows to maintain the peri-implant tissue and improve aesthetics until crown delivery. CAD/CAM enables the fabrication of high-quality implant abutments from solid blocks of different materials.
