Previous studies have reported the management of Class I and II papillary defects, but knowledge on Class III defects, estimated to have a poor periodontal prognosis, remains minimal. In this case report, a Class III papillary defect reconstruction was attempted mainly since the patient reported with difficulty in phonetics. In Stage I, autogenous bone graft from the maxillary tuberosity and subepithelial connective tissue graft was augmented to decrease the distance between the interdental bone crest and contact point, simultaneously achieving a switch in the periodontal biotype. In Stage II, subepithelial connective tissue graft was augmented to achieve papillary fill. To avoid manual errors associated with quantifying the posttreatment outcomes, image data processing ImageJ software was used to assess the length, perimeter, and surface area of papillary loss using the preoperative images.
先前的研究报道了I类和II类乳头缺损的处理方法，但对于估计牙周预后较差的III类缺损，相关知识仍然非常有限。在本病例报告中，主要由于患者自述存在发音困难，因此尝试进行III类乳头缺损重建。在第一阶段，取自上颌结节的自体骨移植和上皮下结缔组织移植增加了牙间骨嵴与接触点之间的距离，同时实现了牙周生物学类型的转变。在第二阶段，增加上皮下结缔组织移植以实现乳头填充。为避免与量化治疗后结果相关的人为误差，使用ImageJ软件对术前图像进行处理，以评估乳头缺失的长度、周长和表面积。
