Treatment Cases

Director Kim Seo-yoon's team presents a short-implant case that avoids bone grafting

For a patient told that a sinus lift was needed because of insufficient bone height, a 6 mm short implant and a digital guide halved the operating time. At the one-year follow-up the bone remained stable with no resorption, and the approach is drawing attention for greatly reducing the surgical burden on elderly patients and those with systemic conditions.

Dr. Park Ji-hoon presents a non-extraction orthodontic case combining clear aligners and mini-screws

For an adult patient advised to have teeth extracted because of protrusion, clear aligners and mini-screws were combined to improve the profile without extraction. Tooth movement was calculated in advance with 3D simulation, shortening treatment to 14 months, and a stable bite was achieved with no gum recession or root resorption.

Dr. Lee Su-ah saves a molar at risk of extraction with microscope root canal treatment

After two rounds of root canal treatment the pain persisted and extraction was recommended. The molar was retreated under a dental surgical microscope; a fourth canal missed in earlier treatment was found, disinfected and sealed, and a radiograph six months later showed that the inflammation at the root tip had clearly decreased.

Dr. Jung Ha-yoon completes treatment of a child afraid of the dentist using a pediatric sedation protocol

A five-year-old who could not sit in the dental chair because of fear had six cavities treated in one visit with a pediatric sedation protocol. Combined with a waiting room where parents can stay and step-by-step acclimation training, the child can now attend regular checkups without sedation, and parent satisfaction surveys were highly positive.
