Dr. G. Cansu Öztürk, DDS, MSc, is the Clinical Director of GC Clinic, a boutique premium dental practice in Nişantaşı, Istanbul, founded in 1985. She graduated from Ege University Faculty of Dentistry in 2010 and completed her specialist training in endodontics at Marmara University between 2012 and 2016, under the mentorship of Prof. Dr. Semih Özbayrak — the academic founder of GC Clinic and former Head of the Department of Oral Diagnosis and Radiology at Marmara University from 1986 to 2013, a tenure of twenty-seven years.

From 2016 to 2019, Dr. Öztürk served as Assistant Professor and Head of the Department of Endodontics at Yeni Yüzyıl University Faculty of Dentistry, where she taught, led the department, and conducted clinical research. Her work on stem cell applications and probiotics in endodontics has been published in peer-reviewed journals, including Operative Dentistry (2018), and presented at national and international congresses. She is a member of the European Society of Endodontology (ESE), the American Association of Endodontists (AAE), and the Turkish Endodontic Society (TED) — the principal professional bodies that frame contemporary endodontic standards in Europe, North America, and Türkiye.

Dr. Öztürk joined GC Clinic in 2014, after completing her specialist training under Prof. Özbayrak. What began as a mentor–student relationship became a clinical partnership. In 2019, she took over clinical leadership of the practice and launched its international patient programme. She modernised the clinic's infrastructure with 3D Cone-Beam Computed Tomography (CBCT), Digital Smile Design (DSD), specialist endodontic microscopy, and an in-house CAD-CAM laboratory — while preserving the academic foundation her mentor had established. The clinic also expanded its clinical team: Dr. Zerrin Engin Bakkal, a Marmara University graduate in continuous practice since 1995, supports implant surgery, oral surgery, and periodontics. In 2026, GC Clinic was formally licensed for international health tourism by the Republic of Türkiye Ministry of Health.

At GC Clinic, Dr. Öztürk personally designs and performs every treatment plan, from the first consultation to the final follow-up. The clinic sees one to two patients per day. There is no rotation between dentists, no handover between technicians, and no production-line workflow. All implant cases use Straumann (Switzerland) or Nobel Biocare (Sweden / USA), with brand and lot numbers documented in writing and verifiable by the patient's home-country dentist. Every treatment carries a written guarantee — ten to fifteen years on crowns and veneers, lifetime on implant fixtures. If a complication arises, including cases originally treated elsewhere, GC Clinic covers the return flight, treatment, and accommodation in Istanbul.

Dr. Öztürk's clinical focus spans endodontic therapy and microscopic endodontics, single and multi-unit implants, All-on-4, All-on-6, and zygomatic cases, full-mouth rehabilitation, Digital Smile Design with porcelain laminate and E-max veneers, periodontal therapy, and bruxism and TMJ management. The practice is conservative and minimally invasive by design — every plan is built around the patient's clinical condition, not a standard protocol. International patients are guided through a single integrated pathway: remote consultation, written treatment plan with fees stated up front, in-clinic delivery in Nişantaşı, and structured follow-up after they return home. Treatment records — imaging, material lot numbers, and prosthetic documentation — are shared in a format directly usable by the patient's dentist abroad.

“Forty years of practice. Two generations under one roof. One standard, carried forward.”
