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.

Eligibility

Min Age: 18 YearsMax Age: 50 Years

Inclusion Criteria8

Periodontally and systemic healthy patients
Patients aged > 18 years
Non- restored teeth for many reasons (i.e. endodontic failure, unworthy for treatment in deep caries/non-caries lesion and root fracture), locate in the posterior area in the maxillary or mandibular arch indicate for customized implant with no need for additional bone and soft tissue augmentation procedures.
An adequate vertical bone for immediate implant placement.
Implants will be positioned with adequate primary stability so that transmucosal healing can be accomplished.
No taken medications known to interfere healing or periodontal tissue health or bone metabolism.
No previous periodontal surgery at involved sites.
Good oral hygiene and good compliance with the plaque control instructions following initial therapy.

Exclusion Criteria12

Patients with active periodontal diseases (bleeding on probing- probing depth > 4 mm) or those under orthodontic treatment.
Poor oral hygiene (full mouth plaque score > 25% and full mouth bleeding score > 25%)
Smoking habits (> 10 cigarettes/day)
Severe acute or chronic periodontitis
Severe bruxism habits
History of oral/IV bisphosphonates taking
Remote or recent radiation therapy in the oro-maxillo-facial area or recent chemotherapy.
Xerostomia
Pregnant and lactating mothers
Patients who have been received periodontal surgery in the study area during the last year.
Clinical or radiographic signs of periapical pathology contraindicating immediate implant placement.
Implants showing signs of peri-implant mucositis and peri-implantitis during the study period will be excluded from the following analyses.

Interventions

OTHERimmediate implant placement with customized PEEK healing abutment

* 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.
