Dental esthetics need to be defined from the scientific perspective in order to obtain predictable treatment outcomes and avoid the effects of subjectivisms on the part of the dental profesional. It can be deduced that the ideal dimensions in the maxillary anterior sector are difficult to establish. Therefore, the primary purpose of this study was to define the dimensions of the maxillary anterior teeth and the relationships between them. In addition, an analysis was made to reinvestigate whether they complied with the Golden proportion, the RED (Recurrent Esthetic Dental) proportion and the Golden percentage. A total of 2304 tooth corresponding to 384 subjects were evaluated. The central incisor presented a mean width of 8.58 mm and a height of 9.35 mm, while the lateral incisor presented a width of 6.69 mm and a height of 7.75 mm. The mean width of the canine was 7.69 mm, with a height of 8.68 mm. The teeth revisited in this study did not comply with the ideal dimensions in the anterior maxillary sector as established by the Golden proportion, Golden percentage and RED. The information obtained from this study can be clinically applied to restore the dimensions during periodontal surgery, restorative dentistry and prosthetic rehabilitation.
为了获得可预测的治疗效果并避免牙科专业人员的主观因素的影响,需要从科学的角度定义口腔美学。可以推断出,上颌前区的理想尺寸很难确定。因此,本研究的主要目的是确定上颌前牙的尺寸及其之间的关系。此外,还进行了分析,以重新研究它们是否符合黄金比例、RED(复发性美学牙科)比例和黄金百分比。总共评估了 384 名受试者的 2304 颗牙齿。中切牙的平均宽度为 8.58mm,高度为 9.35mm,侧切牙的宽度为 6.69mm,高度为 7.75mm。尖牙的平均宽度为 7.69mm,高度为 8.68mm。本研究中重新研究的牙齿不符合黄金比例、黄金百分比和 RED 所规定的上颌前区理想尺寸。从这项研究中获得的信息可以在牙周手术、修复牙科和修复体修复中临床应用于恢复尺寸。
