Assessment of PCL between dental implant prosthesis and natural teeth using a digital force analyzer.

Background: The prime concern of an implant-supported prosthesis (ISP) is to maintain an optimal proximal contact tightness, which further maintains arch integrity, improves masticatory effectiveness, and minimizes peri-implantitis.

Objective: To investigate the loss of proximal contact tightness between single tooth implant-supported prosthesis and the adjacent natural teeth.

Methods: Forty patients treated by a single mandibular first molar ISP, aged between 18-50 years were selected.
