This prospective randomized clinical trial will evaluate the clinical outcomes of the implant crown fabricated with standard scan body (control) and polyetheretherketone (PEEK) anatomic healing abutment (test).
Subjects of either sex or aged 18 above
requires replacement of a single missing posterior tooth with adequate mesiodistal dimension (≥8 mm)
intact adjacent teeth on both sides with existing opposing tooth condition

Presence of active acute infection
History of malignancy, radiotherapy or chemotherapy
Bone metabolic diseases (e.g.: osteogenesis imperfecta, Paget's disease) or current use of medications affecting bone metabolism
Untreated bruxism or parafunctional habits Docusign Envelope ID: FFD7C6C1-66CB-4359-9662-63230F769528 22

Pink Esthetic White Esthetic Score
The PES will be used to evaluate peri-implant soft tissue esthetics and will be assessed at 3 and 12 months after implant placement. PES includes seven parameters: mesial papilla, distal papilla, soft tissue level, soft tissue contour, root convexity, soft tissue color, and soft tissue texture. Each parameter is scored from 0 to 2, where 0 indicates an obvious discrepancy with the contralateral tooth, 1 indicates a minor discrepancy, and 2 indicates no discrepancy. The maximum possible PES is 14, with scores ≥8 considered esthetically acceptable and scores ≥12 indicating an excellent result. The WES will be used to evaluate the esthetic integration of the implant crown and will be assessed based on five parameters: tooth outline, volume, shade, surface texture, and translucency. Each parameter is scored from 0 to 2, following the same scoring criteria as PES. The maximum WES is 10, with scores ≥6 considered esthetically acceptable.
