About Dr. Alassy
Dr. Hatem Alassy is a Minnesota periodontist focused on gum grafting, dental implants, bone grafting, and sinus augmentation. His approach combines advanced periodontal training, restorative experience, and research in periodontal and peri-implant disease to support clear diagnosis and practical treatment planning. He provides periodontal and implant surgical care at Twin Cities Periodontics in St. Louis Park and Summit Dental in Rosemount.
Clinical Focus
Gum Grafting - Rebuilds lost gum tissue to improve coverage, comfort, and long-term tooth support.
Implant Surgery - Surgical placement and planning for replacement of missing teeth.
Bone Grafting - Rebuilds deficient bone to support dental implants and teeth.
Sinus Augmentation - Adds bone in the upper back jaw when additional support is needed for implants.
Clinical & Research Background
Dr. Alassy earned his master's degree and advanced specialty training in periodontology and implant surgery from the University of Minnesota in 2021. His practice is limited to periodontics and implant surgery, with a focus on gum grafting, dental implants, bone grafting, and sinus augmentation. He practices at Twin Cities Periodontics in St. Louis Park and Summit Dental in Rosemount.
Research
His published research centers on peri-implant disease — why implants develop inflammation and bone loss, and how it can be detected earlier. He is first author on reviews of peri-implant biomarkers and of antimicrobial adjuncts in periodontal and peri-implant therapy. Full citations and DOI links appear below.
Background in general dentistry
Before specializing in periodontics, Dr. Alassy practiced general dentistry in Minnesota from 2004 to 2017, spanning restorative dentistry, root canal treatment, and cosmetic care. He completed the Aesthetic Continuum at UCLA in 2015 and Invisalign provider training, and received the Academy of General Dentistry Fellowship in 2019.
Gum grafting belongs to a field known as periodontal plastic surgery — the surgical correction of the gum tissue that frames the teeth. These cases are judged by gum line position, symmetry, tissue thickness and color, and how the result blends with existing crowns and fillings. Years of restorative and esthetic practice trained Dr. Alassy to evaluate a smile the way a restorative dentist does, and he applies that lens to graft design and implant site development.
