Increasing the vertical dimension is essential to resolving problems associated with deep bite. Restorative dentistry, orthodontia, and oral surgery are the three disciplines that can help to gain the vertical dimension necessary in these patients. This clinical report presents the results of increasing vertical dimension with a full-mouth restorative treatment procedure for a 40-year-old male patient who exhibited severe deep bite. After clinical evaluation, extraoral examination showed a reduction of the lower facial height and protuberant lips, wrinkles, drooping, and overclosed commissures. In addition, intraoral examination showed a severe anterior deep-bite articulation, and upper incisors were in contact with the lower incisor labial tissue. A removable partial denture was made at increased occlusal vertical dimension (OVD) to use in the first stage of rehabilitation. Diagnostic wax-up was performed at the increased vertical dimension. Then, provisional crowns were fabricated according to this increased vertical dimension. Interim prostheses were used for 3 months as a guide for preparing the definitive restorations. The adaptation of the patient to the increased OVD was evaluated. During this period, he was asymptomatic. Following the evaluation period, definitive restorations were completed, and routine clinical assessments were made after 1 week, 1 month, 3 months, and 6 months, then after 1 and 2 years with visual and radiographic examinations.
增加垂直距离对于解决与深覆合相关的问题至关重要。修复牙科、正畸学和口腔外科是可以帮助获得这些患者所需垂直距离的三个学科。本临床报告展示了对一名患有严重深覆合的40岁男性患者采用全口修复治疗程序增加垂直距离的结果。临床评估后,口外检查显示面部下1/3高度减小,嘴唇突出、有皱纹、下垂且口角过度闭合。此外,口内检查显示严重的前牙深覆合咬合关系,上颌切牙与下颌切牙唇侧组织接触。制作了一副增加咬合垂直距离(OVD)的可摘局部义齿用于康复的第一阶段。在增加的垂直距离下进行诊断性排牙。然后,根据增加后的垂直距离制作临时冠。临时修复体使用3个月作为制作最终修复体的指导。评估患者对增加的OVD的适应情况。在此期间,他没有出现症状。评估期过后,完成最终修复体,并在1周、1个月、3个月和6个月后进行常规临床评估,然后在1年和2年时进行视觉和影像学检查。
