摘要

氧化鋯相較於陶瓷具有良好的機械性質，所以近年來被大量地使用在製作固定義齒。然而臨床上發現氧化鋯固定義齒主要的問題在於容易產生瓷鑲面碎裂。為了減少併發症的發生以及維持美觀，因此有頰側燒瓷的改良式全氧化鋯義齒設計的研發。本病例報告為上顎全部缺牙的患者接受電腦輔助無翻瓣植牙手術並立即負荷，以植體支持改良式全氧化鋯完成固定贋復物。詳述術前、手術、技工室操作以及贋復物各個時期的過程以及追蹤四個月的結果。

並列摘要

Zirconia has become widely used for crown and fixed dental prostheses (FDPs), which exhibits superior mechanical properties compared with other ceramics. However, fracture of the veneering ceramics is a major complication for the zirconia-based implant-supported FDPs. Modified monolithic zirconia has been introduced to reduce porcelain chipping and to preserve the esthetics. This clinical report presents a case receiving computer-guided flapless implant surgery with immediate loading protocol and reconstruction with modified monolithic zirconia implant-supported FDPs in fully edentulous maxilla. The pre-surgical, surgical, laboratory, prosthetic stages and 4 months follow-up outcomes are illustrated for complete arch rehabilitation.
