The loss of anterior teeth leads to extreme psychological trauma, along with functional and esthetic debilitations. Healthy anterior teeth play an important role of protecting the posterior teeth during excursive mandibular movement. Loss of anterior teeth induces posterior interference with extended disocclusion time. Posterior disocclusion is critical to remove the harmful force on the teeth temporomandibular joint and eliminate muscle hypertonicity. Occlusal interference is considered as contributing factor to temporomandibular disorder (TMD) symptoms. Prosthesis design should eliminate deleterious tooth contacts. Establishing optimum anterior guidance is a key to establishing harmonious functional occlusion in addition to the correction of the esthetic and phonetic disabilities. This case report explains the steps involved in the rehabilitation of the TMD patient with loss of maxillary anterior teeth.
前牙缺失会导致严重的心理创伤,同时伴有功能和美观方面的损害。健康的前牙在下颌运动过程中对后牙起到重要的保护作用。前牙缺失会导致后牙干扰,使无咬合时间延长。后牙无咬合对于消除牙齿和颞下颌关节上的有害力量以及消除肌肉高张力至关重要。咬合干扰被认为是颞下颌关节紊乱病(TMD)症状的一个促成因素。修复体设计应消除有害的牙齿接触。除了纠正美观和语音障碍外,建立最佳的前牙引导是建立和谐功能咬合的关键。本病例报告阐述了上颌前牙缺失的TMD患者康复过程中的步骤。
