Figure 1 Preoperative clinical assessment of tooth wear and gingival architecture. (A) Maxillary occlusal mirror view: A red oval highlights the maxillary central and lateral incisors (12, 11, 21, and 22), where a moderate loss of approximately one-third of the clinical crowns is evident with significant dentin exposure. The plane of view demonstrates characteristic cupping and grooving on the cusps and incisal edges. (B) Frontal intraoral view: Clinical examination shows gingival asymmetry; the margins of teeth 11 and 12 are positioned more incisally relative to the contralateral zeniths of teeth 21 and 22. Red rectangular highlight this discrepancy in gingival levels. (C) Mandibular occlusal mirror view: This view shows generalized mild attrition and erosion within the enamel of the anterior and posterior teeth. Additionally, the mandibular posterior dentition exhibits multi-surface composite restorations. (D) Right lateral and (E) Left lateral intraoral views. These views demonstrate Angle’s Class I occlusion on both sides.
