简要总结
Dental implant treatment is widely used to reconstruct functional and aesthetic problems in partially and fully edentulous patients. However, implant-prosthetic treatment is not free of possible complications and limitations.Stability of peri-implant tissues appears to be one critical component for long term implant success and is influenced by many factors including surgical trauma, biological width establishment, lack of passive fit of superstructures, implant-abutment connection, etc.
The type of implant-abutment connection(IAC) has been considered to be one of the major factors affecting the peri-implant hard and soft tissues. IAC is the point of contact between the surgical and prosthetic phase and is required to provide adequate joint strength, rotational stability, prosthetic indexing and resistance to microbial penetration.
IAC are of two types- External and Internal connection. Internal connection are further diversified into numerous design in an attempt to achieve better microbial seal and joint stability which include internal hex and internal conical.
Few studies have been conducted on comparing these two internal connections and the obtained results were variable.
The purpose of the study is to comparatively evaluate the effect of two implant abutment connection- internal hexagonal and internal conical on peri-implant soft and hard tissue after occlusal loading.
This evaluation will be done based on following parameters-
1. Hard tissue parameter- Crestal bone loss
2. Soft tissue parameters- Probing depth and bleeding on probing
3. IL-1 beta levels in peri-implant sulcus fluid.
These parameters will be recorded during delivery of prosthesis (before occlusal loading-baseline) and 3, 6 and 12 months after occlusal loading. The recorded data will be tabulated and analysed and results will be drawn.
