Patient awareness of dental appearance has increased, resulting in more demanding esthetic requests. There is also strong evidence that increased esthetics is highly significant for complete denture acceptance and success. Taking notice of patients' perceptions of natural appearance and esthetics, the clinician can incorporate their preferences in the construction of individualized dentures that will be harmonized with their facial characteristics. Despite the evolution of materials and techniques, the vast majority of dentures still fail to look natural. Thus, producing prostheses that defy detection and successfully restore the appearance of edentulous patients remains a challenge for the clinician. This paper presents a clinical case where immediate loading of implants supporting a mandibular overdenture was combined with an opposing conventional maxillary denture to satisfy the high functional and esthetic demands of the patient. It also emphasizes the individualized esthetic performance through customization during their fabrication while taking into consideration the various clinical parameters affecting rehabilitation of the edentulous jaw.
Implant-retained overdentures can significantly improve the patients' function. The esthetic performance of these restorations however, may not be satisfying the patients' expectations and demands. Customizing the artificial gingival areas and individual staining of the prefabricated acrylic teeth may improve the esthetic performance creating natural-looking removable prostheses.
患者对牙齿美观的意识有所提高,导致他们对美观的要求更高。有强有力的证据表明,美观度的提高对全口义齿的接受度和成功度有重要影响。临床医生注意到患者对自然美观的感知,就能将他们的偏好融入到个性化义齿的制作中,从而与他们的面部特征相协调。尽管材料和技术不断发展,但绝大多数义齿仍然缺乏自然感。因此,生产出难以察觉且成功恢复无牙患者外观的义齿仍然是临床医生面临的挑战。本文介绍了一个临床病例,即下颌覆盖义齿的种植体即刻负载与上颌常规义齿相结合,以满足患者高功能和美观需求。本文还强调了通过定制来实现个性化美观效果,同时考虑到影响无牙颌修复的各种临床参数。
种植体支持的覆盖义齿可以显著改善患者的功能。然而,这些修复体的美观性能可能无法满足患者的期望和需求。定制人工牙龈区域和预制丙烯酸牙齿的个体染色可以改善美观效果,创造出自然美观的可摘义齿。
