NEW YORK, NY – September 10, 2026 – Centre Dental, a general and implant dentistry practice in Manhattan’s Chinatown founded in 2004, has set out publicly what a same-day full-arch implant case does and does not involve, in response to what the practice describes as a common habit among implant providers of promising “teeth in a day” without explaining which teeth, or on what condition.

The practice’s position is that the phrase describes a real and well-established procedure, and that the way it is commonly advertised leaves patients expecting something different from what they receive.

Provisional arch versus final teeth

In a same-day All-on-4 case at Centre Dental (the practice also places All-on-X arches with additional implants where bone volume and bite forces support them), a patient who qualifies leaves on surgery day with a fixed provisional, or temporary, arch: a screw-retained acrylic bridge, typically reinforced with a titanium bar, fitted to the implants placed that morning. It is fixed, it is functional, and it is not the finished restoration.

The final prosthesis, usually a full-contour monolithic zirconia arch where restorative space allows, is fitted roughly four to six months later, after the implants have osseointegrated. That interval is not a scheduling inconvenience. It is the biology the result depends on.

When the practice will not fit an arch the same day

Same-day loading at Centre Dental is offered for qualifying patients. Qualification is decided on the bone and on the patient’s medical history, since smoking, uncontrolled diabetes, bone medications and grinding all weigh on it, rather than on the appointment book.

The practice’s protocol requires insertion torque of 35 Ncm or greater before an implant is loaded immediately. If an implant does not achieve sufficient primary stability at placement, the arch is not fitted that day. Bone volume, trabecular pattern, sinus position and nerve pathway are mapped from a large-field cone-beam CT scan before any incision is made, which means the practice generally knows before surgery day whether same-day loading is realistic, and says so at that point.

The practice’s position is that a same-day arch fitted on an implant that has not achieved primary stability is not a faster result. It is a worse one.

The equipment the timeline depends on

A single-day full-arch workflow is a logistics problem as much as a surgical one, and Centre Dental has built the sequence around in-house equipment rather than external turnaround.

An in-house cone-beam CT scanner captures a volumetric image data set of the upper and lower jaws in a single short scan, at a lower radiation dose than a comparable medical CT, showing where the inferior alveolar nerve runs in the lower jaw, where the maxillary sinus floor sits in the upper jaw, and how much bone is available at each planned implant site. Each implant’s depth, angle and position is then planned in software from that scan, before any incision.

The custom surgical guide built from that plan is printed at the practice on an in-house 3D printer, along with study models and provisional prosthetics. Keeping production on site removes the wait for a third-party laboratory and keeps any guide adjustment inside the office. The guide constrains each osteotomy to its planned path, narrowing the variance that freehand placement accepts. Dr. Shi plans every implant in three dimensions and performs every placement himself.

One clinician, surgery through final restoration

Centre Dental was founded in 2004 by Dr. John Shi, who holds a Doctor of Dental Surgery degree from Columbia University College of Dental Medicine, where he was a Gies Scholarship recipient and, in 1999, the only student in his graduating class awarded membership in Omicron Kappa Upsilon, the national dental honour society. He completed a General Practice Residency at Hackensack University Medical Center and implant training through New York University. He is a member of the International Congress of Oral Implantologists, the Academy of General Dentistry, the American Dental Association and the New York State Dental Association, and has more than 20 years of clinical experience.

Dr. Shi performs the work himself from the surgery through to the final restoration, which is also why the practice can commit to a same-day sequence, or decline one, without coordinating across separate surgical and restorative offices.

Serving Chinatown and Lower Manhattan

Centre Dental practises at 139 Centre Street, Suite 306. Dr. Shi is fluent in English and Mandarin, and the practice serves patients in English, Mandarin and Cantonese. The practice’s position is that full-arch implant treatment is a decision patients should be able to understand in the language they think in, including the parts that argue against proceeding on a given day.
