Collins Street Specialist Centre — Dr Joshua Ch'ng

Specialist Orthodontist BDSc (Melb) · FRACDS · D.Clin.Dent — Orthodontics (Melb)

Clinical expertise

Dr Joshua Ch'ng is a specialist orthodontist at Collins Street Specialist Centre, with a clinical focus on digital orthodontics and three-dimensional treatment planning. His research background in 3D image analysis shapes how he approaches diagnosis — more quantitative than a standard clinical examination, and more precise in predicting outcomes. That combination of specialist training and research experience is increasingly what separates good orthodontic care from genuinely rigorous care.

For referring dentists, the practical upshot is that your patients receive a diagnostic workup that goes beyond what a conventional exam can offer, with treatment outcomes planned and documented in a way that's clear and communicable.

Dr Ch'ng's clinical interests include:

• Digital orthodontics — three-dimensional treatment planning and fully integrated digital workflows from intraoral scan through to appliance fabrication
• Clear aligner therapy (Invisalign) — including complex and comprehensive cases that benefit from specialist-level planning
• Traditional metal and ceramic braces across all age groups
• Three-dimensional image analysis for diagnosis, airway assessment, and outcome evaluation
• Invisalign First — early interceptive treatment for children using clear aligner technology
• Orthodontic treatment for adults, including bite correction, pre-prosthetic alignment, and aesthetic concerns
• Management of complex crowding, spacing, and skeletal discrepancies

His collaborative research at the University of Michigan introduced him to some of the most advanced methods of three-dimensional craniofacial image analysis in the world — methods he applies directly in clinical decision-making to achieve outcomes that are predictable, stable, and well-documented.

Training pathway

Dr Ch'ng completed his Bachelor of Dental Science (BDSc) at the University of Melbourne. He graduated with distinction, receiving the Kenneth Sutherland Prize for the highest marks in General Dentistry in 2017, alongside his Fellowship of the Royal Australasian College of Dental Surgeons (FRACDS).

He then completed his three-year specialist Doctorate of Clinical Dentistry (D.Clin.Dent) in Orthodontics at the University of Melbourne in 2018. This postgraduate programme is the recognised pathway to specialist registration in orthodontics in Australia, combining advanced clinical training with a formal research component.

During and after his specialist training, Dr Ch'ng undertook collaborative research at the Digital Clinical and Biological Imaging Archive (DCBIA), University of Michigan — one of the world's leading centres for three-dimensional craniofacial image analysis. That international research experience has directly shaped his approach to digital orthodontic diagnostics and treatment evaluation.

Research and presentations

Dr Ch'ng has presented his research at two of the most respected orthodontic conferences in the world:

• Australian Society of Orthodontists (ASO) annual conference
• European Orthodontic Society (EOS) annual conference

His research centres on three-dimensional craniofacial image analysis and the evaluation of digital treatment outcomes — work that feeds into the evidence base for contemporary orthodontic practice.

Awards and honours

• Kenneth Sutherland Prize — awarded for the highest marks in the Royal Australasian College of Dental Surgeons Membership (GDP) examinations (2017)

Languages spoken

Dr Ch'ng consults in English and Mandarin Chinese, which means Mandarin-speaking patients and their families can engage fully in their care from the first consultation through to treatment completion.

What to expect at Collins Street Specialist Centre

Dr Ch'ng practises within the Orthodontics service at Collins Street Specialist Centre, located at Level 12 & Tower, Manchester Unity Building, 220 Collins Street, Melbourne CBD.

At your first appointment, he conducts a thorough specialist assessment. Depending on what's clinically indicated, this may include digital intraoral scanning using the centre's iTero technology, three-dimensional imaging, and a detailed discussion of your treatment options, expected outcomes, and timeframes. Treatment planning is done digitally, so you can often see an approximation of your anticipated result before treatment starts.

The centre's iTero scanning and 3D imaging capabilities mean patients move through a fully integrated orthodontic pathway — from initial scan through treatment planning, ongoing monitoring, and retention.

No referral is required to see Dr Ch'ng, though many patients come via their general dentist or treating specialist. His specialist credentials are independently verifiable through the Australian Health Practitioner Regulation Agency (AHPRA) public register.

Note: Dr Ch'ng's surname is correctly spelled with an apostrophe — Ch'ng.
