GC Clinic

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.

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. 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. 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

Dr. Zerrin Engin Bakkal is a specialist dentist at GC Clinic, a boutique premium dental practice in Nişantaşı, Istanbul, founded in 1985. She graduated from Marmara University Faculty of Dentistry and has practised continuously since 1995 — nearly three decades of uninterrupted clinical experience. She joined GC Clinic in 2024 as part of the clinical team expansion supporting the international patient programme led by Dr. G. Cansu Öztürk.

Her clinical focus spans surgical and flapless implant placement, oral surgery — including sinus lifting and bone grafting — comprehensive periodontics, and aesthetic dentistry. Within the GC Clinic surgical workflow, Dr. Bakkal contributes to complex implant cases that require advanced bone management, soft-tissue handling, or staged surgical planning. She works exclusively with Straumann (Switzerland) and Nobel Biocare (Sweden / USA) implant systems, with brand and lot numbers documented in writing for every patient and verifiable by the patient's home-country dentist.

Dr. Bakkal approaches every case with an independent clinical assessment — treatment is planned around the patient's actual condition, not a standard protocol. This is consistent with GC Clinic's wider clinical philosophy: conservative, minimally invasive, and never volume-driven. The clinic sees one to two patients per day. There is no rotation between dentists, no handover between technicians, and no production-line workflow. Every treatment plan is owned end-to-end by a named clinician.

GC Clinic operates under the Health Tourism Authorization framework of the Republic of Türkiye Ministry of Health, the regulatory standard for clinics treating international patients in Türkiye. 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. Bakkal's nearly three decades of independent practice bring a distinct depth to the GC Clinic surgical team. Her contribution sits alongside that of Dr. Cansu Öztürk, specialist endodontist and Clinical Director, within an integrated clinical pathway designed to deliver continuity of care from the first consultation through to the final follow-up after the patient returns home.
