02-6298-2875A board-certified prosthodontist is a dental specialist trained in the restoration and replacement of teeth. Dr. Ahn Do-gwan of Yonsei Severance Dental holds dual board certifications in Prosthodontics and Comprehensive Dentistry.
Using Ray 5D technology, a precise digital model of the patient's anatomy is created and computer-simulated surgery determines the optimal implant position before the actual procedure is performed.
Raymill, Rayface, and Ray Studio equipment allow prosthetics to be designed and fabricated in-house. This delivers higher precision and shorter turnaround times compared to external labs.
You can book via Naver Reservation or by calling 02-6298-2875. We are open Mon/Wed 10:00–21:00 (evening hours), Tue/Fri 10:00–19:00, and Saturday 10:00–14:00. Closed on Thursdays, Sundays, and public holidays.

Post-filling sensitivity usually has three causes: ①wrong adhesive system selection, ②not following proper bonding steps and application timing, and ③saliva or moisture contamination during treatment. Using a rubber dam to isolate the tooth, choosing the correct bonding agent for cavity depth, and strictly following each step's timing are essential. When speed is prioritized over protocol, these steps often get skipped — which is why choosing a clinic that follows the correct process matters.
Secondary decay under a crown is typically caused by an imprecise crown margin. When the margin is not cleanly defined to a consistent 0.5mm boundary, microscopic gaps form between the crown and tooth, allowing bacteria to infiltrate. Precise tooth preparation — where the margin line is clearly visible all around — is the critical safeguard against secondary decay and the reason crown preparation demands exceptional skill.
The tooth a patient believes is painful is not always the actual source. Like a detective eliminating suspects, the dentist runs cold tests, percussion tests, and bite pressure tests to systematically rule out possible diagnoses. Cracked Tooth Syndrome is particularly deceptive — it is often invisible on both visual examination and X-rays, making multi-step diagnostic logic essential before any irreversible treatment is started.
Vital Pulp Therapy (VPT) preserves the living tooth nerve when infection is limited and the pulp remains viable — avoiding the need for a full root canal. From a biomimetic dentistry standpoint, retaining the natural nerve and dentin structure is strongly preferable for long-term tooth survival. Eligibility depends on the extent of infection and pulp status, which is assessed by the specialist at diagnosis.
Full lower dentures on a severely resorbed jawbone are among the most technically demanding prosthetic challenges in dentistry. Achieving proper fit requires multi-stage precision impressions (selective pressure impressions), careful bite registration, and biomechanical design — such as the RPI stress distribution system — to prevent denture clasps from damaging the remaining teeth. A board-certified Prosthodontist is the right specialist for persistent denture fit problems.
Gumline erosion is not always caused by over-brushing. The primary cause is the cumulative stress from chewing — every bite causes the tooth to flex slightly, and repeated microflexion at the neck of the tooth causes the enamel to chip away. This is called a Non-Carious Cervical Lesion (NCCL). When sensitivity develops, the lesion can be restored with composite resin contoured precisely to the original tooth shape.
Black triangles between front teeth can be filled using composite resin sculpted to match the natural tooth curve. The process requires bevel preparation to widen the adhesive surface, careful layering and shaping of the resin, and a thorough polishing to achieve a smooth, natural-looking result. Though often dismissed as a simple resin procedure, the outcome depends greatly on the clinician's artistic precision and technique.
Same-day milled veneers are limited by the drill diameter of the milling machine, making it difficult to replicate the subtle micro-contours of natural enamel — often resulting in the flat, uniform look patients criticize online. Handcrafted veneers, made by a skilled dental artisan over several weeks, can match color translucency, surface texture, and light reflection to each patient's unique face shape and tone. Veneers are closer to cosmetic artistry than routine dentistry.
