Design and application of modified CAD/CAM socket‐shield preparation template in immediate implantation in the esthetic area

Abstract Objective Designed and applicated a modified customized CAD‐CAM socket‐shield preparation guide template in immediate implant and followed up for 3 years. Clinical Considerations Socket‐shield technique could improve the esthetic effect of immediate implant restorations by preserving the labial fascicular bone‐periodontal complex at the implant site. While the socket‐shield technique is highly technique‐sensitive. A modified customized CAD/CAM guided template was designed and fabricated by 3D printing. The movement of the carbide bur during preparing the socket‐shield was limited by the socket‐shield preparation template. In this case report, the socket‐shield preparation template was used for preparing the socket‐shield in the tooth root with irregular morphology and the case was followed up for 3 years. Conclusions The modified CAD/CAM socket‐shield preparation template effectively improved the accuracy and efficiency of preparing the socket‐shield by limiting the movement of the high‐speed carbide bur in both in both lip‐to‐palatal and crown‐to‐root orientation. The socket‐shield with accurate morphology could effectively maintain the gingival marginal level and contour. Clinical Significance The modified CAD/CAM socket‐shield preparation template with the depth‐locking ring effectively reduced the technique sensitivity and time consumption of the socket‐shield technique, especially for tooth roots with irregular morphology.
