Title: Isao Ishikawa: A Pioneer in Periodontal Innovation

Introduction

Isao Ishikawa, a distinguished inventor based in Tokyo, Japan, has made significant contributions to the field of dental implants and periodontal therapy. With a total of three patents to his name, Ishikawa's work focuses on enhancing the stability and effectiveness of dental procedures involving cultured periodontal ligament cell sheets.

Latest Patents

Ishikawa's latest patents exhibit groundbreaking advancements in periodontal treatment. The first patent describes a complex of an implant and cultured periodontal ligament cell sheet that can be effectively stabilized in the bone through the periodontal ligament tissue. This innovative approach involves coating the fixture of the inserted implant with calcium phosphate and ensuring close contact between the cultured periodontal ligament cell sheet and the implant.

The second patent outlines a process for producing a cultured periodontal membrane cell sheet. This sheet is developed through culturing cells on a specialized support that includes a temperature-responsive polymer. The method involves regulating the culture fluid's temperature to either above the upper critical dissolution temperature or below the lower limit critical dissolution temperature. This technique allows for high bioadherence of the cultured cell sheet to the surface of dental roots, facilitating dense transplants of target cells and promoting the reconstruction of periodontal tissue.

Furthermore, the laminating of cell sheets aims to create a three-dimensional polarity which enhances the efficiency of reconstructing the attachment apparatus, demonstrating promising applications for treating moderate to severe periodontitis and gingival recession.
