View on ClinicalTrials.gov
Updated Dec 15, 2025
Brief Summary
: Immediate Implant Placement with different materials of customized healing abutment for guiding Peri-implant Soft Tissue Healing in Posterior Teeth: A Randomized controlled clinical trial.
Detailed Description
This randomized clinical trial evaluates the effect of customized PEEK healing abutment versus composite healing abutment regarding Clinical evaluation 1. Gingival margin distance 2. Gingival margin height 3. Gingival contour width 4. Gingival volume in BL \& MD aspects on guiding the peri- implant soft tissue emergency profile in posterior teeth after immediate implant placement
Interventions
Name:
immediate implant placement with customized PEEK healing abutment
Type:
OTHER
Description:
* an intraoral examination will be done and a digital impression will be taken by the intraoral scanner (MEDIT i500) for a pre-extraction digital model, and CBCT will be taken for prosthetic-driven planning.
* Once the treatment plan formulated, both STL (Standard Triangle Language) and DICOM (CBCT raw data) files format will be sent to produce the digital surgical guide with metal sleeve.
* Then, a customized PEEK healing abutment will be made mimicking the anatomical cervical contour and pseudo-CEJ will be made by merging the STL and DICOM digitally and the exterior surface of the healing abutment will be designed to resemble a tooth.
* Then, the technicians will mill the customized healing abutment digital design from a pre-milled 14 × 14 mm PEEK block (BioHPP, Bredent®, Bolzano, Italy) with a non-hex connection type, polished it, and sterilized it.
* The digital surgical guide with a metal sleeve will be back for scheduled patient implant surgery.
Primary Outcomes
Measure:
Gingival margin distance
TimeFrame:
Day 0 - month 3
Description:
The gingival margin distance will be measured from the highest gingival margin point in the buccal, palatal/lingual, mesial, and distal sides to the longitudinal implant line parallelly with the platform plane (buccal margin distance; BD, palatal/lingual margin distance; LD, mesial margin distance; MD and distal margin distance; DD).
Measure:
Gingival margin height
TimeFrame:
Day 0 - month 3
Description:
Gingival margin height will be measured from the highest gingival margin point in the buccal, lingual, mesial, and distal sides perpendicular to the platform plane (buccal height; BH, palatal/lingual height; LH, mesial height; MH and distal height; DH).
Measure:
Gingival contour width
TimeFrame:
Day 0 - month 3
Description:
The contour width will be measured from the outer sur face on the buccal and lingual sides to the implant center on the platform plane (buccal width; BW and palatal/lingual width; LW).
Measure:
Gingival volume in BL & MD aspects
TimeFrame:
Day 0 - month 3
Description:
Gingival volume will be measured on the gingiva above the platform plane for total gingival volume and separated with a mid-mesiodistal plane through the implant center for buccal and lingual gingival volume (total buccolingual volume; BLV, buccal volume; BV and lingual volume; LV).
