Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
* Soft tissue surfaces were lightly covered with barium sulfate powder using a powder spray. CBCT was taken.
* A periodontal probe and a rubber stop were used for the measurement of trans-gingival probing thickness (TPT).
* After that, flap were elevated, and actual thickness of soft-tissue (actual thickness, AT) was measured.
The Analytical phase:
* In order to assess soft tissue thickness and bone levels an electronic digital caliper (Shenhan Measuring Tools Co., LTD, Shanghai) will used for measuring the transgingival probing thickness on the pig jaws.
* A graduated Naber's probe will be used for measuring the transgingival probing thickness.
Soft tissue thickness measurements:
* Intra-observer variability was tested under the supervision of the director.
* For the measurement of radiographic thickness (RT), wet soft tissue surfaces were covered with barium sulfate powder (SoloTop; Taejoon, Seoul, Korea), a radiopaque material used as a contrast medium.
* A probes and rubber stop were used for the measurement of transgingival probing thickness (TPT).
* A rubber stop was placed in contact with the surface to facilitate the measurement of tissue thickness, and then TPT was measured with digital calipers. All measurements were rounded to the nearest 0.01 mm.
* For the measurement of actual thickness (AT), an incision was made onto each marked area. After flap elevation, actual soft tissue thickness was measured using the same method that was used for TPT.
Radiographic examination
* The pig jaws will then be imaged with CBCT.
* CBCT scanning will be performed using a PROMAX R 3DMid CBCT device (Planmeca Oy, Helsinki, Finland) with scanning protocol 90 kVp, 8 mA and 13.58 seconds exposure time with a single 360 degree rotation ROMEXIS software. The jawes will be placed on the horizontal plate of the device. The midline and mandibular position will be adjusted using the laser guide
