To achieve minimally-invasive, precise and predictable intraoral soft and hard tissue surgical outcomes by promoting periodontal and implant microsurgery through education, hands-on trainings, and research to predoctoral students, postgraduate students, general dentists, and specialists.


Periodontal and Implant Microsurgery Academy (PiMA) offers three levels of courses with various time commitments and depth of training for interested individuals with all ranges of experience with microsurgery.

Dentists who have basic periodontal and implant surgical experiences and are ready to bring their surgical skills to the next level can apply for our flagship 6-month or 12-month non-degree periodontal and implant microsurgery program. After finishing this program, the trainee will receive a University of Michigan School of Dentistry Program Completion Letter and become an alumnus of the Academy.

Dental students and dentists who wish to study microsurgery can attend our hands-on courses. These are typically one-week courses that will introduce microscope operating and fundamental micro-suturing techniques. We also offer customized hands-on CE courses throughout the year upon request.

Those who want to know more about microsurgery can attend our webinars and other entry-level training courses. For more information about the courses that we offer, please email course Director Hsun-Liang Chan at

Trainees will have an opportunity to observe microsurgical procedures on our main campus clinic and 2 nearby satellite offices.

Graduate Periodontal Clinics at the University of Michigan

A brand new clinic opened in Sep 2020 on the 3rd floor of the Dental School Building. It has 16 treatment units for non-surgical and minor surgery needs, in addition to 4 shared surgical suites for major periodontal and implant surgeries. There is currently one floor-mounted operating microscope for microscopic procedures and will plan to have two wall/ceiling mounted operating microscopes in the surgical suites.

Padbury Periodontics & Implant Dentistry, P.C.

Conveniently located in downtown Jackson, approximately 30 min west of the Dental School, Dr. Padbury’s office is equipped with one wall-mounted Zeiss Pico microscope for performing routine periodontal and implant related procedures. Dr. Chan practices in Dr. Padbury’s office on Thursdays. Fellows will have an opportunity to observe microsurgeries in this office as part of the training requirements.

Seven Lakes Periodontics

Located 40 min north of Ann Arbor, this is where Dr. Velasquez practices microsurgeries on a daily basis. This office is equipped with 2 wall-mounted Zeiss Pico microscope. Fellows will have an opportunity to observe microsurgeries in this office as part of the training requirements.


Under microscopy, surgical incision, soft and hard tissue management and suturing can be executed perfectly. Detailed surgical skills translate into higher predictability, better clinical outcomes and reduced patient morbidity. Trainees of all Levels have an opportunity to observe various types of microsurgical procedures in our facilities. Trainees in the 12-month non-degree program could have an opportunity to see patients under a research setting, provided with satisfactory preclinical training performances and research training.

Guide tissue regeneration

Regenerative periodontal surgery was performed with the aid of operating microscope, which enabled precise incision, tissue management calculus/dental plaque removal, and suturing.

Guided bone regeneration

Operating microscope allows for precise incision, flap reflection, flap releasing and wound closure.

Lateral sinus augmentation

Operating microscope enables augmented vision during osteotomy and Schneiderian membrane elevation. Minimizing window size could reduce patient morbidity and maximize wound healing for better clinical outcomes.

Vertical sinus augmentation

Under microscopy, the Schneiderian membrane can be seen such that a blind osteotome technique becomes a visible and predictable procedure.

Periodontal plastic surgery

Excellent magnification and illumination from operating microscope enhances performances of soft tissue management and surgical outcomes.

Peri-implantitis treatment

Operating microscope can assist visualizing bony defects and Schneiderian membrane. It can facilitate decontamination of implant surface.

Socket augmentation

Use of operating microscope can ensure total debridement of the socket and via minimally invasive tissue management maximal wound stability can be achieved.


Another strength of this Academy is research activity. Trainees will have an opportunity to participate in our exciting preclinical and clinical research projects. Below are examples of current research projects.

Magnification and microsurgery improved clinical outcomes over non-magnified surgical protocols for recession coverage and treatment of periodontitis, a systematic review with meta-analysis.
