Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
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.
The contours of the healing abutment are based on the contours of a provisionally designed definitive prosthesis. The healing abutment promotes tissue healing and obtains contours that are well-matched with the contours of the definitive prosthesis.
Currently healing abutments made of polymers such as polyetheretherketone (PEEK) which have been used in orthopedic surgery, are used in dentistry, because of aesthetic \& biological reasons maintaining the health of peri-implant soft tissues during healing.
Polyetheretherketone (PEEK) healing abutments can be chosen instead of titanium healing abutments because of their superior properties such as biocompatibility, inert chemical properties, white color, and decreased liability for biofilm accumulation.
Research Question "May PEEK healing abutment have a favorable effect on peri-implant soft tissue that may be related to the superior biological properties of PEEK regarding both decreased biofilm accumulation\& healing stimulation?"
